Tool Arm Accessory Turns 2x72 into Buffer?

[The Mighty Ginsu]

I saw a neat video in which someone added a tool arm accessory to a 2x72 grinder. The belt was used to drive the accessory, which had some kind of an arbor and could be used to turn things like buffers. I can't remember where I saw the video, but I think it was posted on this forum. I can't find it.

Can anyone point me to it? I want to steal the idea.

This sounds like an awesome idea to maximize space starved shops.

I thought I saw that Salem Straub had something like that? Maybe he will chime in.

I built one. Patrice has one too, that he built. They work great!

An arm with bearings, and a caster locked to a shaft running through the bearings, with a 3/4" threaded-cone Baldor arbor for wheels.
You can get the arbor cone from Supergrit, in Baldor category.

Here's another pic i found, hope the link shows up.

Thanks for the help. I found 72" drive belts online pretty easily. Thought they might be sturdier than abrasive belts.

I did something like with a disk sander attachment: http://knifedogs.com/showthread.php?42074-disk-grinder-attachment

Abrasive belts are plenty sturdy for the application. If you think about the heat and pressure they deal with when grinding on a platen, simply driving a buffing arm is nothing...
I use 2x48" belts as drive belts, just bring the arm in closer to the frame. Less vibration that way.
