While my leg vise hardware is still being machined to mate screw and the wheel I’ve been working on the legs. In particular got ready for draw-boring.
My target was 10mm pegs (3/8” approx).
I made them from rough oak stock: first planed it a little, then ripped into beams and planed square blanks about 11×11mm (7/16” approx), so I had about 1mm allowance (1/32” approx). Then I rounded them roughly with the block plane:
At this point dowels were a little bit non-round and a little bit over-sized: time to employ some dowel-cutting jig.
First attempt was with pencil-sharpener jig that I first saw at Wood Gears. Here’s what I came up with:
Despite my hard trying I wasn’t able to tune it to make it work: it just trashed blanks. Failure.
Second attempt was with John Heisz's dowel maker. My version was much less accurate, no surprise it didn’t work well.
The third attempt was my own [re-]invention: I drilled 10mm hole in 4mm (5/32”) thick steel bar—the same bar I used for John Heisz’s dowel maker—then I filed a bevel from input side of the jig (maybe 5 to 7 degrees I guess), then I filed teeth on the bevel:
And it worked like a champ!
So finally it took me just 5 minutes to make it work: two minutes to drill a hole, two more minutes to file bevel and teeth, and one more minute to fine-tune the jig (I enlarged the hole just very-very little so I’d have some little allowance for sanding). And yes, I used corded drill to drive dowels through the jig.
Don’t get me wrong, it’s me who failed with first two attempts, and those jigs are more than fine. But I found that my final version just gives you fewer chances to screw up.
Ok, here’s my draw-boring set: dowels and a guide I made especially for this occasion:
I hope next week my leg vise hardware will be ready so I can make all vise-mounting stuff on the leg and assemble legs finally.
Thanks for reading!
