One grows weary of driving the bus...

I would have thought YouTube would be filled but no...

I’ll seen this somewhere.
It wasn’t crazy complicated.... was just a motor on a rheostat connected to the dish:/
I want to say there was a way the guy referenced the mold tonthe center of the dish to keep it stable.... but I don’t remember how it went.
I’ll keep eyes open
Wouldn’t want one to get weary:)

Here’s what I saw..
I giggle when I see it for some reason... like I’m expecting it to turn into a disk decapitator or something haha

I've seen that. I'd prefer something about less menacing...

That is crazy! I wouldn't want to be in the same room as that once it is up to speed.

I'm in the process of trying to make one relatively cheaply. I've ordered some parts and will report back if it works OK. The issue is the motor. I'm trying to use a relatively inexpensive 24V motor geared down to 100rpm, but don't know if it will have enough juice. I'll post here once I've got it built.

Charles Fox came up with it. It's a dish with a shaft which has a pulley, and is driven by a belt off a motor. Some thin plywood sides along the perimeter. Hook up some dust collection as your please.

My thoughts too....
My eyes get big when it speeds up haha

Check out this thread, and the other thread I reference in this thread:

http://www.luthiersforum.com/forum/view ... rized+dish

Short version:

Buy a cheap Harbor Freight belt/disk sander and harvest its 1750 rpm motor, with its attached pulley, power cord and switch.

Buy some bearings, belts, shafts, and pulleys, such that you can have the motor pulley drive a large pulley on a shaft, and that same shaft has a small pulley. That small pulley drives a large pulley on the shaft that will drive the dish. This reduces the rpm at the dish to the desired level.

Attach a sprocket, or a spare pulley, to the end of the shaft that will drive the dish. Install an off center pin in that sprocket/pulley. Put a center hole in your dish that is the right size for accepting the drive shaft, and an off center hole to accept the off center drive pin.

Install rubber casters in a circle underneath the dish, a few inches from its outer edge.

Cheap, easy, and safe. No more driving the bus.

Have you got access to a cnc with at least a 36" X 36" capacity? I will happily send the Vcarve files if you are interested in making one like mine. You will obviously need to own Vcarve to open the file. I will say it's WAY faster than driving the bus. I'm able to cut a wedge body back radius in about 90 seconds. The top radius in about 20. I have maybe $550US in parts into mine though that includes a set of dishes from Canadian Luthier Supply. Not cheep, but good!

Most dish Sanders are designed to be run at only 150 RPM. Hardly a breakneck pace.

Did you intend to respond to my post specifically? I’m not sure what you are trying to say.

Michael, are you saying you have plans for parts to make one on a CNC?

"I've seen that. I'd prefer something about less menacing..."

If you can find an old food processor you can mount a dish on you can have a multi speed unit that stores away in a cabinet. This one is working out pretty well. No menace here...

Find a used potter's wheel. My friend is a raku artist, and that's the first thing I thought of when I watched him throw a pot. He sold one of his old ones to a local shop, that uses it for exactly what this thread is about.

Yes

I built my current one with a reduction gear from Princess Auto. I did get carried away and had a very nice plate manufactured (machined) that cost me about $750. So all in my sander cost about $1000. You can make one WAY cheaper than that but the reduction gear is only about $140 new and probably available from a fish plant or shipyard around the waterfront for next to nothing. I will send you a picture of mine for reference though.

Thanks
Shane

That would be awesome!

It's gonna require some messin on your part. I'm happy to help out with info where I can. Imagine this with a 24" dish screwed to the backing plate. Someone with a metal lathe for a super basic operation would also be handy.

That looks very practical! Good job!

I'm at mt baker skiing for a few days. I'll send the file when I get home.

No hurry, break a leg!

I built mine out of a gear motor, mdf, a couple sprockets from Ebay and some cheap Ebay Chinese casters for the disk to ride along.

Joey I/m frugal LOl do you have pics of your rig ? or some kind of diagram, I/ve been a DIY er since I was 13 haha thanks
