2020年7月17日 · I just picked up an older ROCKWELL BELT SANDER, model 31-550 at an auction. I'm trying to identify the motor that those came with. All the labeling on this unit is faded away. The machine looks original so I don't think the motor was replaced. It looks to be either a 220VAC or 3 phase, but as I said, I can't tell.

2019年12月6日 · Only drawback seems to be the 1.5hp motor the Rockwell/Delta might come with. A smaller belt grinder might be better for hogging material. You could trick out an old Delta 6x48 with a 3 phase motor and VFD if you wanted to tweak speeds and power? The Kalamazoo 8x60" would be a noticeable step up, but $$$. Biggest problem with the older Rockwell ...

Ive got an old (probably wash machine) motor 1/3 HP with a 2" pulley. It turns it fine with just the lower pulleys turning but havent installed the belt yet.

2022年5月29日 · I have a Rockwell 1 x 42 sander/grinder I bought new around 1974 and it has proved to be one of my most-used machines. I even bought a spare at a garage sale years ago just to get the plastic wheels. I have replaced the original plastic wheels, which proved to be the weakest parts of the machine with some from Jim Liechty.

2002年3月12日 · We have a little Delta/Rockwell 1 X 42 belt sander, Mod# 31-350. We need to find somebody/Co. that can supply the rubber covered wheels. We found some folks that had parts, but these seem to be SOL. Any Help would be appreciated.

2012年4月26日 · 3) Belt tracking - Belt tracking on the Delta machine required fiddling with two open-end wrenches to make the adjustment. I added an easy to reach and adjust knob. 4) Motor- Most Delta machines were equipped with an open dripproof 1/4 to 1/3 hp motor- I am using a single phase TEFC 1/2HP Marathon Motor, an offer an optional 1HP TEFC motor ...
