I wish I'd seen Mike's design before I had mine finished. Those gear motors just seemed so expensive! Oh well...

As with most of us, space is always a problem. I had a spot that was near an available dust port, power, and I had some spare time.

Mine turns 180 rpms unloaded. More shall be revealed if that's too quick. I can always change to a less aggressive grit if it is. The Dishes are supplied by Josh at canadianluthiersupply.com. They are very nicely made dishes, and IMO worth the price. There is a 1/2" gap between the dish and the frame making for excellent dust collection. The construction is all HPL plywood and goes together with 1/4" all-thread, carriage bolts, and nylocs. No screws or glue. It's basically a flat-pack tool. laughing6-hehe

All that's left is to get the dust collection and motor bonded to the cyclone.

Cheers, M

Very nice, I swapped motors on my bandsaw a while back and have a plan for the old motor now.

Wow! That's very cool.

I hope you'll post a video demo sometime :)

If I am understanding correctly -- its vertical to save space? I think most would agree that working with gravity generally leads to more precision. I'd suggest that for those that have to ration floor space, it would be fairly simple to fabricate a wall mounted hinge so the unit could operate in the normal horizontal position then swung to the vertical position when not in use.

Yes. Space saving was important.

I will argue that I have excellent control with my design. I'm able to rest my assembly frame/form on the shelf just below dish allowing me excellent control and the ability to actually see what I'm doing, unlike a horizontal design where I'm forced to lift the frame/form to monitor progress.

I'm happy to share a DXF file with the group if you'd like to make your own. I could also, given time, create a parts list.

The one we constructed which has been sold was similar to the production units (actually most similar to Larrivee) -- load the rim to the outside mold which has corresponding depth stops matching the sander frame, load the mold to the sander, the weight of the mold pushes the rim in contact with the abrasive, sanding continues unattended until mold stops hit the frame. To each his/her own, I am sure your design works for you --- I simply find working on a horizontal plane to be easier and more versatile.

Here's the Godin sander (12:45) same as Larrivee similar to Martin --- and note in the narration Top edge flat back edge contoured, Larrivee and Martin do the same.

If there are positive stops, of course gravity wins....

No contest!

Beautiful work on a well-thought design Mike.

How do you couple the dish to your spindle?

Years ago at Collings, a potters wheel sat in the corner for this job. I have a feeling finding a cheep used one might be easier than making one. Many have a foot pedal with variable speed.
