« Part 15: Hot Pipe Bending Part 16 of Simple Jigs and Techniques series no next part

I’ve built two wooden veneer chopping guillotines I the past and they have worked very well for me but faced with the task of producing over a thousand little fillets for the parquetry on my current project, I decided to go metal. After a (very) little thought I decided that the easy way to go would be pipe fittings.

So ….. I give you the steampunk veneer guillotine!

The process reminds me of Japanese Kumiko screens. Though they are sawing the tiny pieces. Great to see your progress.

OK, stupid question- the pipes aren’t threaded at the pivot, right? Else the cut might be tapered a little? Given the length of the arm, maybe not enough to worry about? With that number of pieces, I can see why you went this route. Cool guillotine, in any event!

3/4” pipe is 14 tpi. so in 360 degrees travel the side travel would be 1/14”. The circumference of travel of the cutterhead is about 64” so that would be a side travel of about 1/900 per inch. My veneer is 1/16” so the side travel while cutting is about 1/14000”
Thanks for making me do the calculation. :-)

Paul,

Thanks for the math lesson (even though it’s probably not woke). That certainly looks like a nice setup for your cuts. What kind of a blade are you using? Is that a purpleheart blade holder?

That is a really cool way of cutting. It’s great to still see you here at LJ’s making saw dust.

Cool idea on the jig for sure.
You’re a better man than me though…even with a cool jig like that, I can’t imagine doing that over a thousand times.
You can’t just buy a bag of those from ‘Harrys fillets and stuff’ down on 10th?
