Wooden rabbets
Adam Cherubini, NJ
>Bugbear,
I read the link you included and am surprised at what appears to be a few obvious omissions. For anyone looking in that didn�t read the link, we�re talking about tuning wooden rabbet planes. Bugbear labels this effort as �non trivial� with which I agree wholeheartedly.
1)I don�t think the taper of the body (body not square to the sole) is intentional. I suspect the taper is purley a function of the quartersawn, heart down, orientation of the stock.
When tuning an old wooden fillester or rebate, you got to take into account the fact that the body has shrunk and the blade has not changed. I think its presence isn�t the problem. The problem you experienced is that it projects too far from the side of the plane. I think you need to leave that arris on the side of the blade, since that will be the corner of your blade next time you sharpen. What you should do is grind off the side of the blade until it matches the body again. I think you�ll find the side of the blade is not tapered, so don�t add any. Again, as you grind the blade away, you need the same width of cut as before or the plane will cease working.
2) I�d like to toss in my idea for squaring a skewed blade in a wood plane. You may not like it. How do you flatten a wooden smoothers sole? Do you plane it? I plane long planes� soles, but I put my smoothers on sand paper on glass. Here it comes. Ready? I�ll understand if this makes your stomach hurt: To straighten a skewed plane iron, I set the plane blade to take the finest possible full width cut then, place the plane on the sand paper and�.yeah, I do. I rub the plane with its blade sticking out on that sand paper until the blade is even with the sole. It makes sense, doesn�t it? The plane�s body is the perfect blade holding jig. I mean, that�s what it is, right? Regrinding and honing the blade after that is a simple affair. Certainly no different than our standard approach.
I should have mentioned that most wooden planes have a little lateral slop. Make sure your plane has some. An old rabbet may have a bit less than its maker intended just because of shrinkage. I have tried grinding a bit of the iron�s tang away to �restore� the maker�s intent, but I don�t anymore (and don�t recommend it). Just make sure the tang is somewhat centered in the body before you go to the sand paper.
