Stroke sander for finishing stainless steel.

Waters Industrial is on the list. Any other thoughts? 72 x 28 with 264 belt.

KBM with two belts--> https://www.kbm-maschinenbau.de/en/machines/details/m2s92 Rough with a coarse belt to keep the heat down and switch to the the 120 for finish. No swapping belts or fish scales on the surface from trying to make a finer belt cut more than it should. You need about 1HP per inch of belt width to really get after it.

Nice but serious overkill for my needs at present. I knew that as soon as I saw the triangle shape. Waters could be well under 20 all in including shipping, abrasives, and options.
I had a Wadkin Bursgreen stroke sander a very long time ago. Went to a sheet metal shop after my use. 10 or more years later it popped up on Craigslist. Sheet metal shop selling it.

I have the double belt Doucet triangular sander which is the lower cost version of the Kuhlmeyer and KBM. It's a good machine, made in Canada, mines got a 10' table and I use it for both weld grinding, surface prep and finishing stainless. Doucet also makes a line of less expensive traditional stroke sanders that I believe have the option for a double belt pulley. You can obviously get by running through the grit sequence with a single belt, but it's nice to easily switch on the fly if you need to redress an area with the coarser belt. Sometimes it's hard to tell until you're making passes with the finer grit.

Volpato is an Italian company that's worth a look. They make good sanders, guessing a little more expensive than the Waters you quoted.
