Thread: New Tapered / threaded mandrel for sanding and buffing razors

Here are some work in progress pics of a new sander/buffer I am assembling using a 1/2" diameter stainless steel tapered & threaded mandrel, 24 : long, that our guy Geezer has made. His intent was to make a mandrel that did not require a separate set of cones on the end of a shaft. This is my first implementation of the sander/buffer and I am using an old arbor setup that I had saved. The clearance on each end is about 8.5 ". Since I will be running it at about 1000 rpm max I expect no wobble. Tomorrow I will be installing the arbor on a table & connecting it to a motor. More pics to follow.

Very cool!

Geezer was very pleased to see your buffer setup on Youtube after he started this project!

Thanks Charlie,
Your solution is a winner for any long shaft!
For those who didn't see it yet here is a link to the grinder/polisher that Randy pointed out to me when he heard what I was doing.

Oh, and here is the arbor before I cleaned it up and before Geezer helped me by getting it assembled correctly...........

Cool, Randy. I'm rebuilding an old pulley driven grinder to use as a buffer. 1/4 hp/1750rpm, and about 3 inches of clearance. Not as long as yours, but it should work a lot better than my 2 speed grinder. Pics on request.

Hey Skip, post some pics of your setup in this thread please. The whole idea is to give people some ideas on how they can get setup.
If you have 3" of shaft on each side that would be workable but very tight.

The other guys are doing theirs also; expect some photo posts soon from them too. They have come up with differing ideas for their own spaces and usage. They stay in touch and ask questions that get me thinking!!

For my first trial:
Not much for looks; it does the job and is reversible when required. It made usable "cheap" prototype and I learned a lot. I got a few better ideas for the next one/s.

Have fun!

Here are some pics from Geezer to give another idea of using it in a lathe.

Looks great Randy, thanks for the pics. I can't wait to see it all setup.
