WOW - a whole bunch of engineering in this one.  A lot more than my humble peddle-powered machine.  Love the way he changes frequency of the AC going into the motor to control speed.  Thanks for the link, Lew

pretty cool project but I think I'll stick my store bought saw

Same here. I would be hard pressed to find the time to make one of these. My store bought one still works.

I do believe I'll pass on this !!!

And I was scratching my head recreating parts for my old Delta's.

Did you notice the cheap  DIY sand blasting box next to the scroll saw?

I'm glad I stumbled on this post. The speed control is so simple.  It is just components: (1) a  solid state relay  the on off frequency of which is controlled by a (2) PID controller .  Both, things you can get for cheap on the Flea Bay. Depending on the PID he may or not have needed a cheap wall outlet adapter to convert  and drop voltage to something lower or the PID might be able to run on line voltage.

The Cheap PID and relay makes for a fabulous speed control which you can put on almost any motor.

Puts me to mind of other applications where fussing with belts and pulleys is a bother.

Here is another scroll saw.  Notice the background? It's an industrial setting not a garage workshop. Did he make it at home and bring it in or was he doing Guv'ment work.  I'd have gone with belts  instead of the  cage gears to make it quieter.

Like he said, functional but not practical - that's what I ran into making mine - changing it from "functional but not practical" to "functional AND practical".

Clearly it was a work of love.

There's no way I'd make lovely spindle spokes for a flywheel on such a machine - nor would I make such a nice flywheel. Mine would be a hunk of scrap  plywood mounted with a block of wood at the center (for  the shaft) with weights screwed to the periphery.     He had an unnecessary joint in his treadle  linkages  too. Got a tad carried away I guess. 

You do all that scroll work on a machine you made?

Where's the pics?  gotta have pics~!

Cliff - LMAO

That was pretty neat.  An inspiration.
