Good catch on the tape; I use blue masking tape and plane until I hit it, which is easier than gluing cardboard on as some advocate. I've also seen articles discussing the use of a saw with a mitre jack, and claiming a French origin for the tool: http://theparttimewoodworker.blogspot.com/2010/08/saw-that-never-was.html http://www.leevalley.com/en/newsletters/Woodworking/5/5/collection.htm The idea is that you saw first, then finish with a mitre plane. The saw shown in the photos looks perfect for this purpose, and I'd really like to find or make one. Are there any other ways to use these things? Any other galoots who have made and/or used one of these want to weigh in? -- Adam, sometimes backwards in Port Angeles WA ------------------------------------------------------------------------ |

ggs: I used a mitre jack with a plane for a good while, but then I got a guillotine mitre trimmer (just like a Pootatuck but made by his brother-in- law, I believe) can't recall the maker's name---anyway, I sold the mitre jack last August at the Best in the West PNTC extravagoonza and a guy from Lee Valley bought it. I can't remember his name either, but he told me all the old time guys used paring chisels, on account of the plane cutting in to the jaws doing it my way. My way was to send the work through the jaws a little more than I wanted to plane off; I used a mitre plane, and practically never hit the jaws. They'd been hit before I got it, plenty, but it still worked fine for me. Since using such a tool is art, not science, you can do it with a roller or a brush, so to speak, and if you're building your own mitre hack (how hard can it be?) you can be the boss of how it's utilized. I do *like* the idea of paring with the work held suchlike, but it never occurred to me. best to all---gammage If you were Einstein's father, we wouldn't have the bomb."

Crawling out from under the porch and dusting myself off... I made a different type of mitre jack a few years ago when I was making some furniture with triple miter joints. Wiktor was kind enough to host my story about this on his website: http://www.wkfinetools.com/tMaking/art/miterJack/miterJack-1.asp This worked really well and I don't think I could have gotten these joints to fit properly without it. For the last couple of years I have been working on building bamboo fly rods. Just finished my fifth one and I feel like I am still on the steep part of the learning curve. I've gotten to the point where I can enjoy using them for fishing, but still have a ways to go before I could ever charge money for one. The assembled bamboo rod has a hexagonal cross section and is made of 6 strips which have an equilateral triangle section. The grooved block plane used for planing these on the steel form has a groove which is 0.003 inches deep. This allows the plane to be used on the form without planing into the surface of the form. I only use this plane for the final passes, using a Stanley #18 for taking off most of the material to that point. A key point about using the grooved plane for this application is that the groove must be wider than the strip which is being planed. I don't know that this would be the case when using a grooved plane on a miter jack? This restriction would limit the stock to be less than about 2/3 the width of the plane sole. Best Regards, Ted, who is still around, just not speaking up very often. ------------------------------------------------------------------------ |

Fly rod makers use a block plane with a groove rabetted down the center of the length of the bed. They use a metal tapering jig that is very clever that allows them to make the hexagonal pieces that glue into the rod sections and make them tapered in a controlled fashion. The sole of the plane rides on the jig, while the rabetted part planes the piece - the blade never touches the jig. How about a #3 or #4 sized plane with a 1/16" or so groove down the length of the sole for the same purpose on a miter jack. Better minds than I have looked at this for centuries, and I have never used a miter jack, but, hey, I'm just sayin'.

I found that I needed to use a shoulder plane to square the joints in my triple miter tenons. See the second to the last photo of my story on Wiktor's site. I did occasionally gouge into the surface of my mitre jack with the plane while making my joints, but it really isn't a problem until you mangle it sufficiently to mess up the geometry. Even then, it is not too difficult to bring it back with a few minutes of careful planing of the surface. Regards, Ted ------------------------------------------------------------------------ |

Hey Ed--- I once saw in "Smithsonian" magazine, I believe, an article about Hoagy Carmichael, Junior, who does that---builds split bamboo fly rods and works them as you describe. This particular article had some seriously detailed close photos of the bench and the process. That would be pretty light work, the 'timbers' weighing a couple of pounds apiece, and the jointer plane being a #60 1/2, or a #65--- what a wonderful world--- gam off to work in OlyWA If you were Einstein's father, we wouldn't have the bomb."

Ted Good point. Could we add a small extension to both sides of the plane - like a thin piece of wood clamped to each cheek - for the plane to ride on the jack? I am picturing a 1/16" piece of flat steel just smaller than the plane sole sitting on another flat piece, then clamping a piece of 3/8 hardwood onto each cheek so that it fully contacts the lower piece of steel. Too much trouble - like GAM says - just be careful. Ed Minch ------------------------------------------------------------------------ |

Better minds than I have looked at > this for centuries, and I have never used a miter jack, but, hey, I'm > just sayin'. A farmer and part-time fly-rod maker who once borrowed a book from me on fly-rod construction, still, so far as I am aware, shapes his rod segments using wooden forms and a couple of the humble Stanley 110 block planes. I do not think that he has had grooves or slots milled down their mid-lines. However, Ed's description of a grooved plane and its use for rod-making sheds a sudden light, for me, on a "curiosity" which was displayed by a fleaster for several weeks before someone bought it. This "curiosity" was a block plane, it may have been a Stanley 110 but I do not remember, which had four pieces of what appeared to be shim brass of moderate gauge sweated to its sole in such a way as the mouth was left unobstructed to its full width whilst, as I view it through my mind's eye but from a new, Ed-generated perspective, there was, in effect, a channel or groove left along the sole's midline, about 1/3 of the sole's width, as I recall. There is little doubt that, if perusal of the List remains part of one's daily routine, all of life's little mysteries will, sooner or later, be revealed.
