“Hey, aren’t you done with that thing yet?” You know I can’t make something without a carving decoration. So…
Here’s the harder one first. Carving straight lines along the grain line is harder than carving curves. While I’m never satisfied with a carving, this one is done enough to set aside and wait for its partner.
It’s all Shannon’s fault. During his review of a Bontz saw, he mentioned an Art Deco feature in how the saw’s back was shaped. That sparked an old interest and I was off to re-explore the genre and come up with a couple of designs.
The curvy one is next. And yes, I’ll cut a saw plate some day.
So, what are those threaded holes for? Threaded rods, of course. And the adjustable fence.
The fence itself is pretty simple, two pieces glued together with holes drilled to allow sliding along the threaded rods. Tom Fidgen planed off the bottom piece at an angle, providing a way of resting the plane at an angle which keeps the blade off the bench. I liked the idea and did the same.
Now, the threading… I’ve read good and bad (too often more bad than good) about the quality wood threading kits. I was almost tempted to use metal parts (Hello McMaster-Carr), but decide to give the Woodcraft 3/4″ threading kit a try. It’s worked out very well! No problems, no horror stories. The cutters are plenty sharp enough for producing good results on cherry. I was careful to chamfer entry points, to lube the tap with BLO, and to soak the dowels overnight in BLO before threading.
The dowels are right on 3/4″ diameter, ripped from 4/4 stock and then turned on the treadle lathe.
The nuts too are turned. I stacked four 4/4 blocks together with double sided tape, sawed off the corners and turned on the lathe. Each was then drilled with a 5/8″ auger and tapped. Easy-peasy. I left them round, rather than putting flats on the sides, because they are easy enough to grip and don’t need much torque to do their job.
It comes together very nicely, allowing the fence to be adjusted right up against the blade. I’ll cut the threaded rods down some after I decide how far I might really want to extend the fence.
Resawing lumber is a part of many projects, from big long boards for the hulls of boats, to fine hardwood boards for boxes. It’s time to take resawing accuracy to the next stage. I follow the usual technique of sawing from all 4 corners and flipping frequently to stay on track, or for a very long board, still flipping frequently side to side. Even so, going astray a little bit and recovering often produces the dreaded “X” in the middle of a board. That’s sometimes a hump, with matching divot in the other piece. I’ve never had an error of that sort serious enough to ruin a project, but I would like to spend less time “cleaning up.”
No, don’t blame it on my saws. They are terrific and I keep them wicked sharp. It’s the guy pushing the saw.
Tom Fidgen published his solution, a “kerfing plane,” on his blog and in his recent book Unplugged Workshop. The idea is to produce a kerf of reasonable depth on all edges of a piece of lumber, and then use that kerf to guide the saw. We’ll see if it makes a difference.
Tom started with a fixed fence version and converted to an adjustable fence version. I’m going straight to the adjustable version. Here’s a start at the main body, in cherry. The “stains” near the upper holes are from linseed oil used to lubricate a tap for threaded holes (more on that later). The blade, needing teeth, is from an old Disston. The saw nuts are from Issac Smith’s Blackburn Tools.
Does anyone want a “honey pot” for advertising spam? This blog collected 3,355 spam comments in the past 24 hours. Very fortunately, AKISMET (most highly recommended) caught all but 4 of them.
That’s about 5 million percent better than the spam filtering on Blogger! … and the reason all those Blogger folks use CAPTCHAs. Blogger itself should be doing the spam filtering instead of making visitors jump through CAPTCHA hoops. (Blogger’s parent, Google, has a most excellent spam filter as part of GMail, but can’t seem to find a way to use it on Blogger.)
Way to go AKISMET!
