GG's: The real problem in interpreting that recipe isn=3Bt the gill=2C which is a quarter of a pint (somewhat still in use=2C although today we'd probably describe that as "1/2 cup". The real problem is the pennyWORTH. Note that that is not a pennyWEIGHT=2C which is 1/20th of a TROY ounce.

Further to, or in addition to the usual discussion on soaking in linseed oil (or not), I just found this in Spons Workshop Reciepts, 1883, page 86: Polishing or Oiling: Planes. Planes made from naturally dried beech- wood are much lighter in colour than those made from artificially dried or steamed beech. For planes made of the first-named beech, use raw linseed oil, 1 gill; dragon's blood, 1 pennyworth ; yellow ochre, as much in bulk as dragon's blood ; mix these together, and rub the planes all over except the sole or bottom ; let them remain about a week. Take them and rub well all over with a clean soft rag ; give one more coat of oil alone. Let it dry for three or four days, then rub well with a clean rag ; lay them by for a week or two ; rub again with rag, and use them if wanted. Let care be taken to keep them free from dust while the oil is wet, or they will be a dirty colour. For steamed beech proceed the same, except not to use more than about half the quantity of dragon's blood. No soaking there.

Matthew Groves asked: > Does Clark and Williams finish the sole of their planes? > Yes, all surfaces are finished with Minwax's Antique Oil Finish - applied as a wiping varnish. In other words, the oil/varnish is liberally applied to the surfaces, then all the surplus wiped off before being allowed to dry. This is followed with a light rub-out and a coat of high quality furniture wax (i.e., without silicone, etc.). When the sole needs trued, usually due mostly to seasonal/environmental changes, it is an easy matter to refinish and re-wax as desired, with these readily available materials.

Yes; it is this treatment that I'm addressing. It appears from Spons that this was NOT "usual" in 1883, or at least that an alternative existed. And by 1928 Woodworker said that soaking was wrong - so wrong that manufacturers would not warrent a tool so treated So the question becomes; "in what period was a full linseed soaking usual?" I certainly recall a reference speaking of a plane being weighed, soaked in oil, weighed again, and the weight of the taken-up oil being charged by the shop that owned the barrel of oil, but I can't remember which reference :-( BugBear ------------------------------------------------------------------------ |

John and all, It is my understanding that the linseed oil treatment was something they did in Great Britain. For some reason it was not as common in America. If you look at old American planes they are typically lighter in color because of this. Mike John Manners wrote: > |

The inimitable Bernard Jones had this to say on the topic (The Practical Woodworker, original c. 2nd decade of the 20th century, this from the 10-Speed Press facsimile edition, 1983), p. 55: "A plane should be 'oiled' before using; this makes it heavier, lessens the friction, and thus makes the plane work easily. A reasonably heavy plane is better than a light one, as it works more solidly and does not require so much pressing down on to the work. If the plane, therefore, has not been oiled, or is too light, it should be soaked in raw linseed oil or other suitable oil until it is a suitable weight. This is usually done by suspending it in an oil tank. If this is inconvenient the cutter and wedge are taken out, the bottom of the mouth of the plane is stopped with putty, and the mouth filled with oil After a few days the oil will have soaked into the plane; add more oil until sufficient has been absorbed. Planes are sometimes french-polished, but this is not necessary." The companion volume (The Complete Woodworker, p. 38 of the 10-Speed Press facsimile edition) has this to say: "In the case of new planes it is a good plan to soak them well with linseed oil a short time before using, and then, by well rubbing the surfaces, a dull finish is obtain, and by following this with an occasional rub, the surfaces are kept clean and in good condition. Some people oil a new plane by removing the wedge and irons, stopping up the mouth on the face with putty, and then filling the mouth with linseed oil, leaving it until the oil exudes from the pores and the end of the stock; it is allowed to dry, and then polished with friction."

The lighter color has to do more with the difference between English beech and American beech. I have seen American planes that were oil treated as I have seen English planes that were done that way. Usually it was a once and done type job and not something done on a regular basis. The other issue is the fact that the English continued to work in the traditional way for a lot longer than the American's did. By the end of WWI, almost all furniture making in this county was done in factories. Not saying that there weren't any smaller traditional shops but they were fewer in number. Over in England a lot of the cabinet makers continued to use hand tools up to the WWII era. A lot of rural England (if my reading is correct) wasn't electrified or only marginally so until after WWII. So English planes have a lot more working patination on them. This is also born out in the fact that the last American wooden plane makers were gone, at least the major ones by the time of WWI and there were still firms making planes in England again up to WWII and a little beyond in a few cases.

Thomas Ellis wrote: > Anyone have any idea how long it would take a > plane treated like this with raw oil to dry well > enough to use? Almost exactly thirty years ago, I tried this very treatment on a plane I'd just made. Never again! To this day, if it hasn't been used for a short period of time, the wedge/iron assembly still tends to stick in place. And, it has always been harder to adjust than it needs to be because of the "stickiness" in the escapement. As to adding weight, as one who has done long planing sessions over a number of years, any extra and unnecessary weight just adds to the work load. Consider that many of the 19th century patents for metallic planes included claims regarding lessening the weight of the planes. Also, consider that the small amount of weight added by the oil is completely inconsequential when compared with the downward pressure we can, and do, apply to the plane during the stroke. There may be some slight lubricating advantage to this practice, but keeping some means of lubricating the sole of your planes at the ready on your bench obviates this. Finally, as to claims for stabilizing the wood body of wooden planes - again, I think there is no clear evidence for this. One contemporary wooden plane maker habitually soaked all of his planes in oil and made very strong claims about the stability this engendered. After a couple of years of feedback from his customers, he completely reversed himself regarding any such claims - and ... quit soaking them in oil. In line with this, it's been my observation that very few of the antique wooden planes I've encountered over the years show evidence of this kind of treatment.

Bill Taggart writes: > How about glazer's putty? Seems to me that should work, non? Indeed it should in circumstances where linseed oil and whiting putty made the glazier's traditional putty. Some used the later latex putty on the grounds that it "shock-proofed" the pane but it never seemed to dry and was almost impossible to paint over. Linseed oil putty can be made to dry and harden a little more quickly than otherwise, which is helpful for glazing, or, at least, for painting over the putty, by the addition of some mineral turpentine to the oil. Surplus linseed oil putty can be kept in jar of water and later used after wringing out the water and kneading again with a little linseed oil. Modern putties which come ready- prepared with a secret recipe of herbs and spices may be a different kettle of fish (or chook), of course, but many glaziers still prepare their own putty for big jobs just like their grand-dads did.

To answer the last question, I don't recall ever seeing a whole plane submerged in linseed oil and my earliest recollection of seeing the mouth puttied up and the throat filled with oil is from about 60 years ago, the plane being one newly bought by my uncle and left sitting on a shelf above his father's (my grandfather's)workbench with a stern injunction to me and my brother not to touch it. Thereafter I became further acquainted with the practice from conversations with tradesmen and, in particular, from a piece recommending it in one of the weekly articles on carpentry and cabinet- making which appeared in our daily newspaper in the early fifties. I was a little bit awed to see in print a write-up of the same process which an uncle of mine had undertaken a few years previously. It is not thought that the tradesmen of my acquaintance in the late forties and early fifties ever had the advantage of reading Spons or the 1928 "Woodworker". They read about the politics of the day and the "Guide to Form" and were quick to criticize the weekly article on carpentry if they believed it to be in error. A classmate of mine who left school at 14 and became apprenticed to a carpenter showed me one of his Technical College books which consisted solely of reprints of all of the newspaper articles. I doubt if many copies of this tome survive as it was printed on newsprint and stapled between light cardboard covers in those days of austerity. A warranty for a tool? No tools were warranted here until the late sixties or early seventies except Sidchrome spanners. If the plane split apart on its first run down a board or the head flew off the hammer the hardware store proprietor would insist that it was the customer's fault and avoid drinking in the same pub as his customer for the following six months. All we had was the Sale of Goods Act, all very fine in its own way but, in reality, confined in its use to the more plutocratic members of the commercial community who could afford to engage legal representation concerning, say, the quality of a shipment of several hundred tons of wheat to a flour-mill. No "consumer watch-dogs" then. It is clear from the wooden planes that I have acquired that, although some still show putty marks just inside the mouth, most were not give any treatment preliminary to their being put to work and it is just as clear from some of the metal planes I have bought that their new owners did not even bother to stone the iron. With so little guidance ever being on offer to the neophyte handy-man it is little wonder that he resorted to power tools in a big way when they became plentiful and comparatively cheap, even before the Chinese saturated the power-tools market, and were the only things written about in the newly arrived, generally available woodworking magazines. The proof, for me, is in the pudding. Every newly acquired wooden plane gets, at least, its dose of oil poured down its throat. Cracks significantly larger than the hairline variety disappear within a few days and the tendency on the outside grain of coffin smoothers to run out at the midway bulge is subdued. Longer planes, such as jointers, try planes and jacks, which show signs of having had a bit of merciless treatment with a hammer at either end, are further treated by having their ends dunked in linseed oil for a couple of days and are then permitted to drip out for a day or so, closing up most of the more fearsome cracks developed by their early mistreatment. The obdurate cracks in the top are simply puttied up with very moist linseed oil putty with a bit of turps added to hasten drying. When the plane looks and feels dry enough, and this seems to depend on the ambient humidity, I then attend to flattening it sole and, if needs be, patching the mouth. The patch material is oiled, a bit of mineral turps being mixed with the oil to foster drying, and left to dry for a few days before it is cut and fitted but this does not appear to affect the glue job adversely. I hesitated to treat my European planes having lignum vitae or suchlike soles in this way for fear that the sole might detach or the different woods would expand at different rates. Eventually, I experimented with one of these planes which was something of a wreck and found that everything proceeded happily enough and, gradually, I successfully oiled all of them and flattened their soles. It is probably something to do with the harsh, dry seasons which we experience here but some old wooden planes manage to digest their throat full of oil in less than a day. However, I leave things at that and do not bother re-priming them. A treated plane certainly whips down the workpiece with much less friction resistance than its desiccated cousin.

Just to clarify: I wasn't advocating, mind you. I was attempting to add some specifics on the lore discussed especially by our antipodian brethren regarding puttying the mouth and filling up the resulting cavity with linseed oil, and letting'er soak and soak. I have not tried it, and don't intend to, but Bernard Jones apparently thought it was the cat's pajamas, in the early 20th century. I have wiped wooden planes down with my usual mix of boiled linseed oil cut half-and-half with mineral spirits, but Don's experience confirms my suspicion regarding full soaking with raw (or even "boiled") linseed oil.

The aftermath of WWI followed by the depression in the thirties and the post WWII austerity years meant that very few could afford to set up what then would have been state-of-the-art furniture factories and quite a lot of common and cheap furniture was produced by relatively labour- intensive means in numerous localities. I don't know when Mathieson & Son in Glasgow stopped exporting their wooden planes to us but, judging by the number still appearing at the fleas, it seems that these exports must have been resumed at some time following WWII. However, there seems to have been a period after WWII when we were driven to rely on our own resources as is testified to by the appearance of wooden planes of European pattern but made of Australian hardwood by Bergs during, I think, the late forties or early fifties. At the same time as Bergs wooden planes made their appearance quite a few Australian manufacturers of metal planes came on to a market which really had been starved for new tools. All of the planes at the manual arts schoolroom which I attended were wooden ones with the exception of one metal jack, jealously guarded by our teacher. I think that wooden planes retained their position in the market here for quite some time because of their comparative cheapness.

My thanks to Tom Holloway for furnishing some nice, definitive statements from yesteryear on the subject of oiling wooden planes. It had not occurred to me that increasing the plane's weight was a consideration, my own endeavours being directed to the thoughts of holding the plane's body together, getting it to resume its correct shape before flattening the sole and reducing friction. I am now emboldened to give some of my planes which proved to be particularly thirsty additional doses of oil. Regards from Brisbane, John Manners ----- Original Message ----- From: "T&J Holloway" |

Tom Ellis writes: Anyone have any idea how long it would take a plane treated like this with raw oil to dry well enough to use? Usual unsatisfactory answer is, "It all depends". Mostly, I think, on the ambient humidity. It certainly dries more quickly if some mineral turpentine in, say, 1 part of turps to 4 parts oil ( I seldom measure these things with any accuracy) is added to the oil. If this is done it should be dry in less than a week. If considerable oil sweats through the wood (this rarely happens) it is cleaned off with turps and if the oil disappears from the throat but leaves a slight residue the throat is washed out with turps, leaving the throat dry. It is supposed that a plane may become super-saturated with oil but the right balance seems to be easily regained with use of turps. I most cases the oil just disappears within a week.

Galooterati: Tom Ellis asked: "Anyone have any idea how long it would take a plane [soaked in] raw oil to dry well enough to use?" I don't know about raw oil, but around twenty years ago I bought a "new old" English smoother, one of dozens of identical planes found in a barrel in a hardware store completely unused and never finished in any way. I stopped the mouth with glazier's putty and kept it full of boiled linseed oil until the oil showed at the ends. As best I remember it was dry enough to handle and to have been used in a couple of weeks. As it happens the plane never has been used, but that has nothing to do with the oil: the problem is that the blade is made out of pot metal. This was my first wooden plane and I sharpened it and set it and tried it over and over again trying to get it to work; it was only when I had other, old, planes to compare with it that I really convinced myself that the steel was bad and simply wouldn't hold an edge. I've often remembered bitterly the amount of work I put into that plane before I tried sharpening it. Someday I'll get a decent blade for it, or maybe try hardening the one it has. Before soaking in oil the wood of this plane was very pale, but the oil turned it a gorgeous dark red. I had a similar experience with my first bookbinder's sewing frame, also of unfinished beech and many years old when I bought it: it turned from the palest biscuit to deep red when I soaked it in oil. Somewhere in my experience I think I have seen two items from the same piece of wood, soaked in oil immediately after purchase with fresh-cut surfaces and soaked in oil some years later after sitting and oxidizing for all that time. Both looked pale-biscuit before finishing, but the fresh surface didn't darken much with oil while the old/oxidized surface darkened strikingly to a deep red. In consequence I have never been quite convinced by the claim that American beech is paler than European beech: I have seen old/unfinished European beech as pale as any American beech I have seen, and I have seen American beech that darkened markedly when an old surface was oiled. I think the apparent difference is more a matter of different seasoning and finishing practices than any real difference in the wood.

A few (well, OK "many") year ago I did some experiments with this method. I used BLO - the heavy metals dryer type. I took a bunch of beech blocks - about 3"x3"x15", bored a good sized hole in the middle (where the blade would go if it was a plane), and filled it with oil. After a good soak - long enough that the oil was coming out the ends of the wood, I checked them daily. Most of them had skinned over in a few days, but a decent scratch in the wood would expose wet oil. After a few weeks, a deep scratch wouldn't expose wet oil, but a split would show that the oil was still wet in the middle. Some months later, splitting one open revealed that he oil had polymerized all the way to the center. I didn't check to see if the hardness or durability was effected, and I didn't have either raw or non-heavy metal laced BLO available... -James -----Original Message----- From: oldtools-bounces@r...

Boiled linseed oils dries out quickly to form a film and it is thought that it would not penetrate the wood to any great extent.

With two of them, although the beech timber was sound enough, the irons were as Tom describes, incapable of holding an edge. A Czechoslovakian firm made similar planes but with a bead along the side under the "Tigre" brand but their irons are superb. The maker of the planes with the dud irons did not bother to disclose his name or country of origin on his products but I suspect that were made in the U.K. shortly after the war when good materials were as hard to come by there as they were here. My reason for suspecting that they were made in the U.K. is that I have what appear to be older planes of identical pattern with "Sheffield" on the irons. Fortunately, I had managed to acquire at the flea what must once have been someone's stash of old irons, doubles and singles, amongst which were several 1 1/2" or 40 mm irons, one being a "Two Cherries", which replaced the original apologies for irons quite satisfactorily. These little planes can easily be used in one hand and are useful for all sorts of light cleaning-up work.

The problem with the use of oils to stabilize wood is that they don't do it. What oils actually do, for a short period of time, is to add bulk to the cells of desiccated material. However, the oils tend over time to weaken the wood, and to chemically react to things present in the wood (such as tannins) and to outside influences (such as air pollutants and who knows what that comes in contact with the wood). These reactions can under some circumstances be very bad for the wood. It is possible to use various kinds of polymers to semi-permanently strengthen and bulk the cells of the wood. These treatments have not yet been commercialized, but they are used in some of the top archaeological preservation labs. It is a question of longevity. Oil today may help today, but may assure that the tool does not last another full generation. Does one care? Joe Joseph Sullivan -----Original Message----- From: oldtools-bounces@r...

Indeed. However, the treatments I mentioned are quite a bit different from the stuff the boat guys use. The labs use specialized active polymers that penetrate the wood and cross-link, but are invisible to the eye. I have handled leather, wood and textiles that have been submerged anywhere from 300 to 4,000 years, treated with the new methods, and thereby stablized to the point that climate control and even white gloves are no longer necessary.

This is interesting - here we always sing the praises of a nice, beefy, tapered, forged blade - and here is Woodwork 1930 dissing it in favor of a drawn (I presume) steel parallel-sided blade. I dunno that I would characterize such a thing "A much better type of blade"... Especially in a woodie. And the assertion that the reason there was a steel bit forged onto an iron back was because "it is easier to grind ha1f-and-half steel and iron than to grind a solid steel blade"? I have always understood it was because (1) steel was a more precious commodity back then and (2) the iron absorbed the shock better, while the steel held an edge better, so the combination of the two made a better blade. And as far as the back being "left rough-forged"? That doesn't always have to be the case.

The reference was Woodworker 1930, not 1928, and included the notion of dipping and weighing. Herewith: Forty years ago it was the general practice to take a new beechwood plane to the chandler's or oil stores to have it soaked in raw linseed oil. The oilman generally weighed the plane minus the blades and then proceeded to tie a piece of strong twine to it, after which he threw it bodily into the drum of linseed oil. In a week or ten days the owner, usually an apprentice, would call and the oilman would withdraw the plane from the drum by hauling in the twine. After the plane was drained the oilman again weighed it and charged the owner for the oil absorbed plus his labour. The plane was left for a few days to allow for oxidation of the oil, after which the blade, etc. was adjusted and the plane put into action. Another method was to putty up the mouth of the plane and then to pour raw linseed oil into the escapement, after which the plane as allowed to soak up the oil, which was, if necessary, replenished once or twice. Nowadays the plane makers decry such treatment, and at least one firm issues a danger label printed in red which distinctly states that if the plane be soaked in oil their warranty ceases. The accepted treatment at the moment is to wipe the plane over thoroughly with a freely charged linseed oil rag every day for from seven to ten day's, after which the plane is fadded-in with french polish. One is apt to refer to work done in the "good old days" so why this alteration in treatment? First of all let us examine the end of a plane and we shall see that, if a careful selection of timber has been made. the annual rings and the medullary rays wll run approximately as shown at Fig 1. In other words, the blocks from which the plane is made has been quarter sawn. If cut as at Fig. I the sole stands up to the wear better and the tendency for shrink is minimised because it is more or less in the direction of the arrow. To illustrate this this more forcibly look at Fig. 2, where the effect of circumferential shrinkave is shown, and it will be obvious that, if the plane block were cut like this, the side of the plane and its sole would soon cease to be at right angles and this shape would be practically useless when used in conjunction with the shooting board. Soaking the plane in oil has a tendency to swell the wood and cause undue distortion, whereas if the plane is gradually oiled the pores are filled gradually as the oxidation of the oil takes place. The appli- cation of a little french polish as a finishing process further seals the pores and makes for cleanliness. Swelling the wood with oil also causes the frog (or the part on which the blade beds) to become twisted, and this produces "chattering" and imperfect cutting when the plane is in use. Another cause of chattering i(s a faulty blade. Most planes are fitted with a tapered blade, as at Fig 3, consisting of a small piece of steel which is forged on to a wrought iron blade, The idea being that it is easier to grind ha1f-and-half steel and iron than to grind a solid steel blade. Many of these irons are left rough forged at the back and consequently they do not bed accu- rately on to the frog of the plane.

I daresay it is a terrible pity that John Leather, Fellow of the Royal Institution of Naval Architects, member of the Society for Nautical Research and author of the book that launched, around these parts at least, a thousand? small boats, did not have the benefit of the theology founding the above proclamation in all its binding infallibility. In his "Clinker Boatbuilding" of 1973 he clearly badly misguides himself and his readers and sends men down to the sea in death-trap dinghies when he heretically states: "With all possible waste and dust removed ........ the boat may be given a preservative coating. Traditionally, this was a coat of linseed oil and paraffin (kerosene), mixed in proportions of two of paraffin to one of oil. This can be brushed on liberally and will soak well into most timbers forming effective and cheap preservative." There must be a first class miracle or two still in prolonged operation, however, or some form of naval exorcism has been undertaken, as some clinker dinghies, built after John Leather's style in the eighties, are still furnishing enjoyment to their owners who sail them.
