261256 | Thomas Conroy | 2017‑01‑13 | Angle of skew chisels |
O Galoots: This one rambles a bit before it gets to the poin, but with patience we can get aroound all four bases. When we went fleaBAGging in December, Bill Kasper gave me a couple of little handleless chisels he had picked up to me. One is a 1/4" Dunlap, not a stellar brand, with about 3" of blade, but in good condition----back reasonably flat, discoloratin but no corrosion. I put it to the back of my mind and cooed over the other one, a bevel-edged socket Ward's Master Quality 3/4" wide whose only drawback is that I already have quite a number of 3/4" chisels. Then Bill Ghio sent me, unsolicited, a dead pretty little Buck Cast Steel 5/8" of about the same length (3-1/2" blade) with a short, comfy handle and a note that "I was given this chisel several years ago by another Galoot. I liked its small size so much that I decided to make up a set of butt chisels for the bench. Over time that grew into a complete set of short PEXTO chisels and this one became redundant. However, I have felt that since it was gifted to me I could not sell it. Today while wrapping my Galootaclaus gift I noticed it and it occurred to me that you would appreciate this little guy<" I do indeed; I love small chisels. Thanks, Bill, I am looking forward to this doing its business again, and forming the nucleus of s set of 3-1/2" bevel-edged butt socket chisels. If it turns out to be a set of uniform Ward Master Quality, then I will pass your Buck along to yet another galoot. And in the meantime I have it sharp and ready to use on my desk, sitting next to the Ward from Bill Kasper. I keep wondering if I will end up with a whole set of chisels obtained from guys named Bill. I'm joking, but what I mostly feel is joy at having good friends. So, back to the other chisel Bill Kasper gave me, a non-stellar Dunlap BE socket. After a month or so it occurred to me that it is just about a match for another I have, a Fulton (another non-stellar brand), one of my first chisels and long since relegated to the "second or third set" box. I bought this one before I grew snobbish about chisel brands and it gave good service for years, but was replaced in my bench rack by a longer, more elegant Swedish chisel. With two fairly close in shape and quality, I have a potential pair of 1/4" skew dovetailing chisels. Twenty-five or thirty years ago I ground a couple of nice 3/4" chisels into a skew set, and have never found a use for them. I don't think I have used them even once. Then, maybe ten years ago, a big box of cast-offs burped up a couple of cast steel tang chisels worn down to 2-1/2" of blade, and I ground them skew and put them in matching ebony London Octagonal handles. Around the same time I read that skew could be used for cleaning out dovetails, and experiment showed me that this waas indeed a good use for them. However, for the size dovetails I was doing (in boards under 1/2" thick) even a 3/8" chisel seemed too large and heavy; so I've been looking for a couple of quarter-inchers to regrind. I was imagining another pair of thin tang chisels worn short, but with the Fulton and Dunlap falling into my lap.... So I'm regrinding my non-stellar pair. They are, as 1/4' chisels often are, grossly thick, as thick as they are wide near the socket, so to get them thin enough for a dovetailing pair I will have to grind off at least half the thickness in the inch or two nearest the edge. I've taken the Fulton down to 1/8" at an inch from the edge, and 1/16" a quarter inch from the edge. This completely removes the bevel-edging in the ground areas; I haven't yet decided whether to re-bevel the edges. I would hesitate a long time before doing this much surgery on a name chisel, or even one marked "cast steel" and nothing else, but hey, it's a Dunlap and a Fulton--- no great worry if the regrinding proves a frost. And we get to the point of this email. I'm almost ready to grind the skew on the front. And I need to decide what angle is best for small dovetails. Opinions seem to differ on this. Anyone care to give an opinion about what angle is right for a dovetailing skew? Lie-Nielsen does a very mild 20 degree skew. Most makers seem to favor a more pronounced skew; some seem to go all the way to a 45 degree skew. I'd probably go for a pretty pronounced skew, maybe 30-35 degrees (my first set was around 40 degrees, and y second around 25). But I'd like to hear what other galoots think is most useful. Also, I have to decide on ha dle size. I might retain the conventional handle on the Fulton, and make one similar for the Dunlop. The fulton is 8" overall, with a handle 3-3/8" long and a blade 2-3/4" long to where the shoulders would be on a wider chisel. However, I am strongly tempted to give both chisels burin-style mushroom or palm handles,moving the right hand closer to the edge. Again: Anyone have opinions or experience on handle length for a dovetailing skew? Enquiring minds want to know. Tom Conroy |

Tom, My .02 for free here. I learned to cut half-blind dovetails when taking a class from Lonnie Bird. He does not use a skew chisel when cutting these dovetails, instead he uses a 1/8 inch chisel to accomplish the same purpose of getting into the corners of the sockets. His 1/8 inch chisel is a bit different though. He had a 1/4 inch chisel that he had ground to 1/8 inch wide for an inch or so up from the tip. He said he did this because a 1/8 inch chisel is so narrow that it tends to roll in the fingers (he holds, and taught us to hold the chisel by the blade close to the tip using the thumb and first two fingers), whereas a 1/4 inch chisel does not tend to roll but easily stays flat in the hand. I had an 1/4 inch Two Cherries chisel that I ground in the same fashion and that's what I use when cutting half-blind dovetails and it works a treat. I don't own narrow skew chisels for cutting dovetails as there is no need with this modified tool. Cheers, John John M. Johnston jmjhnstn@m... “P.S.

Hi Galoots Well, apparently I needed to write today. I hope its not unpleasant. I am really liking where this subject is heading! I would appreciate seeing the triangular ground chisels?? And I would like to know if anyone thinks another geometry might work even better? I am thinking a whole triangular shaped chisel, say 1/2" where it meets the socket, and then the whole Maryanne tapered in practically every dimension to make, like an angular jointsticker? Stiletto corner jabber? .... Or something? What I am saying is that is has been too long since a took a piece of innocent steel to the grinder and had at it. Breathing grinding dust, can be addictive. (as long as you watcha you ass, you'll be ok. Just don't get tooooooooo greedy lol) Taking a piece of hardened tool steel, and making it bow to your will, is not nothing. When its radically changed and you saw it happen? That is something. Keep yer dunk cups handy Boys! heeheheh Oh, and if there is a woman in your life, remember to wipe your teeth! The worst telltale giveaway sign you have been dabbling in steel? Yeah it accumulates on your front teeth. You smile at your sweetie and she points and hollers............Little Rascals! @ ! Cause you look like Alfalfa. So Conroy, did you really mount ebony handles on 2 1/2" chisels, and can I see? I never had ebony chisel handles. I love the idea, just not enough spare ebony, ever in my life, to make any. Chisel blades I can get easy, it seems. They must just want to live at my house. I have a drawer now. And yet I still desperately need a 1/4" bevel edged chisel! My heart was horribly broken recently. So I still need a full length, straight, 1/4" socket chisel. I would like the full 6" of blade, or near enough. Most any brand will do. If its a 6" blade, plus the socket, chisel............. and its still straight? It had to have been something in the first place. Nobody ever made a bad 6" blade chisel is my point. Not that I ever saw anyway. My heart is broken, because I found an actual Baker and Hamilton, San Francisco chisel last year. A full length 1/4" socket chisel. I bought a small lot of homeless chisels just to get it. But it was bent. And badly. And all my best tricks failed. I get to save 3 out of 4, but there is still a 25% failure rate at straightening old chisels. And the poor little B&H just exploded before my eyes. Along with my nervous system and then my heart, one split second later. Booooooooooooooo Baker was an early wheeler dealer of near Gold Rush California. He was partners on the first glassmaking enterprise (Baker and Cutting) and then got involved in the first try at building a big hardware firm. Baker and Hamilton. The glass was a miserable failure, btw. B&C glass is poorly annealed and it explodes at a touch. Its killer beautiful, if you ever find a piece of it. Early, crude, brilliantly colored, loaded with bubbles. Rare........ Everything a bottle collector could ever want. Just don't handle it much. lol But Baker and Hamilton was a different story and the hardware business was solid for many years. Stiletto tools was Baker and Hamilton's house brand. They seemed to have ordered quality goods, as every Stiletto marked tool I ever had was good stuff. Oh btw, some of the early Fulton's were pretty damn good. Sears went from one maker to another over the years, always looking for a cheaper price. (and we have the nerve to complain about quality?) But occasionally, they were forced to buy quality merchandise. Some of the Fulton were good...... Most were not, but some of them. By the time they got to Dunlap though, it was pretty much construction tools from there on out. Sears went to mostly the construction market. Can't blame them. 100 carpenters for every joiner/cabinetmaker. Follow the money. yours Scott -- ******************************* Scott Grandstaff Box 409 Happy Camp, Ca 96039 scottg@s... http://www.snowcrest.net/kitty/sgrandstaff/ http://www.snowcrest.net/kitty/hpages/index.html |

I made a pair from random 1/2" bevel edge socket chisels and I made the angle 45°. It is very easy to use the entire edge of the chisel to cut into the side of a tail or pin by pushing on the side of the blade. One has an original handle that was short, and one I made out of Osage Orange a little longer and they are about right https://www.flickr.com/photos/ruby1638/32169097121/in/dateposted-public/ Ed Minch |

I hear some say that they use a 1/8” chisel to clear the corners of dovetail sockets. What this tells me is that they do not make drawers with fine (“London” style) dovetails. Such as these … http://www.inthewoodshop.com/Furniture/TopOfTheWorldToYou_html_m233f38e0.jpg or these … http://www.inthewoodshop.com/Furniture/MakingBetter%20Dovetails_html_47 d0c311.jpg">http://www.inthewoodshop.com/Furniture/MakingBetter%20Dovetails_html _47d0c311.jpg Sawing and chiseling fine pins does not leave any room for error .. http://www.inthewoodshop.com/Furniture/Londonhalf- blinddovetaileddrawer_html_m6296be34.jpg">http://www.inthewoodshop.com/Furniture /Londonhalf-blinddovetaileddrawer_html_m6296be34.jpg Some prefer skew chisels. I find that these need a shallow angle (20 degrees), otherwise you are forced to skew the chisel to slice a cut. Much better - my preference - is a fishtail chisel. These just need to be pushed into the corner.

261271 | "Linda & Tom Hall" <l-thall@c...> | 2017‑01‑14 | Re: Angle of Skew Chisels |
I bought a set of Japanese chisels about 30 years ago from Garrett Wade for making dovetails and have never used them, time fly's. There two crank necks, 6mm and 28mm, matching right & left skew chisels at 6mm and 28mm. The angle of the skew looks to be a little under 35 degrees, quiet pointed. They look to be ground for making dovetails also the crank necks look like what you see in ad’s today. I haven’t seen ad’s for the Japanese skew chisels. Recently I contacted Garrett Wade and Product Specialist Joe Wolfe got back to me that he believes they were made by Iyorol. I would love to get them into users hands, I’m quite embarrass they have just sat there all these years. Is there anyone out there that uses Japanese chisels that would be interested in buying or trading other tools. Contact me of list l-thall@c... for pic’s. But to Tom Conroy request the skew is about 33 degrees. Tommy Hall Amesbury, MA |

I knew they existed but never thought why. Agree with Ed, though. If there is an error to be made, I make that error, so there had better be room for it. Of course, at this point my skills are not at a par with either of you. Today I am putting the third coat of shellac on a cradle designed and made by me of wood I cut on family property. I'll do four coats wet-sanded and then a top coat of Behlens Rock Hard to make it diaper proof. Here's the thing, though: I have spent more time correcting mistakes than I have building and finishing. Of course, except for the cradle floor, the cradle and stand are ENTIRELY curvilinear so once cut reference to true is largely lost unless the maker had the foresight to mark everything necessarily carefully and indelibly in the square. This maker lacked that foresight, so it has been an exercise for the eye. Right now, in mid-finishing stage, small issues are still coming to light -- visual, not structural. Some I can correct, others must simply stay. My son and daughter in law for whom this is intended are both architects, with, therefore, trained eyes. I will have to ask them to be forgiving as although it is imperfect, I have done my best. Joe |

Derek, mostly I've used a 1/8 inch reground from a 1/4 inch to deal with the inevitable shmutz in the corners of dovetail sockets. In addition to large case pieces with large pins and sockets, here is a piece I did several years ago using that modified 1/8 inch chisel. http://galootcentral.com/component/option,com_copperminevis/Itemid,2/pl ace,displayimage/album,lastup/cat,0/pos,0/">http://galootcentral.com/component/o ption,com_copperminevis/Itemid,2/place,displayimage/album,lastup/cat,0/pos,0/ Apart from that, I'm looking at four drawers for a Pennsylvania slant-front desk in the immediate future so I am very interested in knowing more about your particular fishtail chisel, where you obtained it, and any particular further observations based on your experiences using it.

Before they came out with those fish chisels I just got a couple of crap chisels and ground them at an angle. Crap chisels are a dime a dozen and the rarity of use ( cleaning corners) lets them shine because the demands are so low. |

I also used a thin knife to get in there and work the corners. If I had to do a bunch of them, I think the fishtail or a narrower skew would do it, but since time was not of the essence, the knife worked well. And if you opened up my joints you would not find the precision and beauty that were able to achieve. Ed Minch |

Joe It’s not a mistake unless you can’t fix it - and I have found that paint is wonderful invention. Last year I built a toy chest for third grandchild - lovely Georgia. I made a mini - blanket chest with dovetailed corners, a till, and two drawers at the bottom, all done with hand tools except the surface planing. I finished the corners, then hand-cut the dados for the till, only to find that I had dadoed the outside of the front rather than the inside of the front. The dovetails, of course, did not fit when I flipped the front over, so they had to be patched up, but my choice between stain/varnish and paint was made FOR me. Ed Minch |

'Lo Galoots Assembled, To return to the matter of a 3/8 inch wide fishtail being too wide for small work. Probably the smallest dovetail work I'll ever do is in gallery of little drawers in a spice box, or in the gallery of a Pennsylvania slant-front desk. These are also similar in size to small boxes I've made using half-blind dovetails. I just measured all of the drawers in the spice box (13 drawers) and none of them are too narrow to admit a 3/8 inch chisel, either at the base of the socket or between the narrowest opening of the pins along the face. Having never used a fishtail chisel for trimming half-blind dovetails, I could see using it to trim the inside corners from both directions, registering the chisel flat on these surfaces and cutting with just the one tip in the corner. Derek, do you use your mallet with it, or just hand pressure? I could see the fishtail chisel as a more precise and less damaging alternative than a standard 1/8 inch chisel. I'd like to hear more from Derek about his fishtail chisel and how he uses in in cutting half-blind pin sockets, and other woodworking applications. Cheers, John John M. Johnston jmjhnstn@m... "P.S.

261305 | Derek Cohen <derekcohen@i...> | 2017‑01‑15 | Re: Angle of skew chisels |
John asks about making a fishtail chisel, and grinding lands. John, the reason the fishtail does not appear on my website it is that it was made more than 10 years ago, which is when I migrated from Wiktor’s fine site (where I had the honour of being the first contributor) to start my own. There are some tools that are really so easy to make, and the fishtail is one. As many here will attest, grinding steel just needs a light touch and a coarse wheel, and it will not burn. I chose a ratio of 1:7 for the shape of the fishtail, since that is what I use most often. Mark the shape you want on the steel, and then slowly grind away, dipping in water to keep it all cool. I must mention that I have a few other fishtails, both shop made and production. One does not need more than one of these chisels (… do as I say, not as I do!), and the only size I use is a 3/8”. Wider than this is unnecessary since the chisel is only used in the corner of the socket. A bench- or paring chisel is used for removing most of the waste. Grinding lands on chisels is a little more complicated. One could do this freehand and get decent results, but a jig/guide is a better way of achieving uniform results if you plan to grind the entire length of the blade. This is increasingly difficult as the blade width becomes narrower. Wide blades have more registration and are easier to orientate. But one wants narrower chisels for skinny tails. Of course, one only really needs to ensure that the first 1” of the blade has minimal lands, since the depth of a board is unlikely to be greater than this. The smallest chisel I have ground was made from a 1/8” wide HSS bar. I used a bench grinder with a cambered wheel, and a Tormek track with Veritas small blade holder … http://www.inthewoodshop.com/ShopMadeTools/Soyouwanttomakeadovetailchis el_html_35d3f454.jpg">http://www.inthewoodshop.com/ShopMadeTools/Soyouwanttomake adovetailchisel_html_35d3f454.jpg http://www.inthewoodshop.com/ShopMadeTools/Soyouwanttomakeadovetailchis el_html_50398606.jpg">http://www.inthewoodshop.com/ShopMadeTools/Soyouwanttomake adovetailchisel_html_50398606.jpg Hope this helps.

I had three, now have only two pairs, don't know where the third pair ended up, but I think I gave it as a galootaclaus gift to someone. The first set was home made, using cheap garage sale plastic handled Stanley and Millers Falls. Don't recall the width or angle Second set was a Lee valley set, ground to about 32 degrees, thicker and clunkier than most. http://www.leevalley.com/us/wood/page.aspx?c=&p=30025&cat=1,41504,41539&ap=1 Third set was a set of 12mm Nooitgedagt pair hand ground by Dutch galootaclaus Marten Haugen (SP?) at about 20 degrees. This is the most used set of the three, but not for Dovetails, but rather all other work. https://kirkhmb.smugmug.com/Woodworking/Woodworking-Tools/i-J2sbQ78 And while struggling with dovetails, Scott the Happy Camper hand ground a triangular 1/4" one for me, seen here. https://kirkhmb.smugmug.com/Woodworking/Chisels-Gouges/i-wb6JRVh This gets hauled out every time I try dovetails. Kirk in HMB, CA, where rain starts again tomorrow. |

I remember you had sent me a miserable plastic handled grocery store quality something to grind. (ewwwwwwwwww) When you said you might mention it, I was mortally afraid that is what I had sent back. But..........at least I scrounged up a little socket chisel for the occasion!
