Belt grinder plans?

[QSIMDO]

Not looking for a 2" knife grinder but something maybe 4" - 6" wide.

Got a 3600 rpm , 3 hp, 3 phase Baldor motor for power just beggin' for a job.

That sounds like a lot of HP for a 6" belt anything. I would think about a 1/2 HP motor.

I disagree with this. I have a 1.5 horse on a 6" belt and can stall it. 3 hp sounds about right.

I agree....

Lakeside,

You agree with Sarge or Larry_g ?

I'm thinking a 6"x 72" or 120" belt and wheel assembly.The 3hp would make a killer general use belt sander. The glazer in the shop uses a 6"x72" wet sander on all his window glazing replacement pieces to cut the edges, and it works real well with a 1.5hp that we replaced a couple of yrs ago because of bad bearings.
I say bigger is better, GO FOR IT!!

I have a 1.5hp 6 inch belt sander and a 2x72 3hp. The problem will occur on larger grit when hogging. Take your time and you can use any hp. You really should slow down the belt for finer grits anyhow.

A Jancy 4"x79 is 4hp and Burr King 3x79 are 3-5hp.

I say bigger is better too.
6" >> 5hp min.

I have a a little over 3hp on my 2" x 72" belt grinder and when I have a 36 grit belt on it I can bog the motor some grinding steel.

The lowest HP recommended for the NoWeld 2x72" is 1.5 HP.

Around here 3" units seem to be 4-5.5hp and 6" units 5 to 7.5hp so OP's 3hp is definitely not an overkill.

Yeah, do you want to grind steel or fall asleep to the purr of a belt gently caressing and warming a piece of Fe?

OK, you guys all done now?
Can't say I didn't expect it.

Here's the deal; I'M LOOKING FOR PLANS for a belt grinder...WIDER than 2 inches.
I PRESENTLY HAVE a 3hp motor and that's what I'm using, period.
DON'T WANT a knife grinder but if one can be scaled up so be it.
I emailed Tom Lipton because he had a video on his DIY Baldor-esque grinder but he get's more email in a day than Amazon so no response.

I've searched but little other than plywood framed sanders comes up so...does anyone have/can point me to plans?

Start by sourcing reasonably priced contact wheel

Homemade tools.net might have some. I've been looking at building a belt sander for a while (2x48 probably) and I've just found a lot of pictures to go from. Most people seem to work with the material and skills that they have, so every one I've seen looks different.

The stock is in my lathe, ready for turning.
