  1. Thanks! That's really good of him to be available like that. I'll keep that in mind for the next mystery tool that comes my way.
  2. Now that we know what it is there is a modest interest in trying in out, at least to cut some circles, and maybe a compound curve or two. If/when that happens we'll definitely video the event and post it for your viewing pleasure :-)
  3. That never occurred to me - I just wrote to their customer service email account. So Rob Lee takes email directly from guys like us?
  4. I think I have it figured out. Thanks to everyone who had a suggestion. The two points are not scribes, they are pivots. The idea is to line up your work, pin down the pivot point, and the curve you want to cut will be kept tangential to the blade. You push the work through the blade and it will rotate about the pivot point. There are two points so you can smoothly cut two successive tangential curves in the same workpiece in a single operation, e.g. an S-shape. The pivoting arm is there to let you set up your work before putting it up to the blade, and the stop is of course there to prevent the arm from accidentally encountering the blade. Lee Valley abandoned the tool after a short production run because the pivot points are too small (weak) to hold thicker workpieces reliably and there's no easy way to fix this short of redesigning the trammel points and their holders. But I think it'll work great for thinner stock. <ahem> If anyone is interested in acquiring this tool, well, let's talk! --WorkMonk
  5. I do think this tool is from the pre-internet-everything era. Maybe it was for some sort of inscribing of arcs, but it seems a bit overwrought for such a simple task - why not just use a regular beam compass with multiple trammels? Also the pivot is so heavy duty, and it's bolted down to a plate, and there's the business of the stop - why would you need a stop? It limits the arm travel to about 350-degrees. I'm thinking maybe it was supposed to move material through a bandsaw blade on a repeatable partial curve, and the little pins (which are spring loaded) are there to secure the work during movement. Lee Valley says '5-6 business days before we can respond to new emails'.
  6. More information! After fishing around in the barn we found the base for the bar. It's a Veritas tool called "Multi-curve". It is very nicely made, and the donor included a base plate made of melamine. But I still don't know what it's supposed to do! Maybe the Lee Valley guys will remember something about it...
  7. Ha, ha! Yes, well, I sent them a picture and am waiting for a reply; in the meantime the internet is my friend!
  8. The 'pencil holder' won't fit any standard pencil, but will grab a fat-bodied marker, like a Sharpie. It might actually be a some sort of special beam compass, maybe there's some missing parts. Asking Lee Valley is a really good idea! I'm going to take it in with me whenever the lockdown here in Ontario lifts...
  9. A friend gave this to me 6 years ago, said it was from Lee Valley, but I don't know what it is... At first I thought it was a beam compass with trammel points, because of the two slide-able spring-loaded pointy bits and the nice aluminium extrusion beam. But the trammel holders are mounted at 45-degrees on a rib coming off the main extrusion, and there's a hollow brass pivot or attachment point which is off-center from the trammels. There's also a spring-loaded round-hole clamp near the brass pivot, with a brass knurled activator knob. It's a puzzler for sure. Any clues appreciated!
