i found a new 5hp motor, that is less expensive than most 2hp motors, i plan on using it for a heavy duty belt grinder for flat grinding. do you guys think this is too much horse power?
 
Magnum,
I run 5HP 220v motors on both of my belt grinders. They run 108" belts with the contact wheels turning on 1"dia. shafts and bearings. As Tom said, there is no such thing as too much power! My next toy will be a variable speed grinder that will probably have less HP for finishing.
The reason I use the long belts is that the company I work for uses them for their cam grinding machines. I get slightly worn ones for free and can order new ones at a good price. A 108", 36 grit belt on a 5HP grinder can remove material in a hurry

Magnum,
One more thought.....Are you talking about a 5HP compressor motor?? They sell them at great prices in the catologs but they dont seem to have much power! I have one that I originally had on my ginder and it had no B***S! I don't know how they rate compressor motors but I would estimate that mine, that was brand new only had about 1HP!! I'm using an industrial, sealed, Dayton motor on one grinder and a Grizzly motor on the other. Both unfortunatly cost way more than the compressor motor

dr. lathe if my 220v line can handle the 10hp motor in the piranha 36ton hydraulic press my father has then it sure can handle 5hp. yup, this is a compressor motor, do you think i should go for a tefc 3hp regular motor? or should i just save up the money and buy a real 5hp motor? i'm glad there is no such thing as too much power.
briggs and stratton, isn't that a gas powered motor?
oh yeah, to reduce sound i'm surrounding the motor with 2" of acustic lining.
 
TSC has a compact 12 horsepower briggs and stratton engine that would work great

Thats gas powered though, if you really want torque you gotta go for a diesel

Magnum,
I based the design of my belt grinders on the machines at my job. I run the 5hp motors because the belts I use are longer and heavier. I'm turning MUCH heavier shafts and bearings and my idler wheels are also VERY large(12"). Even with the 5HP motors, if you saw one of my grinders start up, you would see what I mean!!! The TEFC motors from what I've seen are the way to go. A 3hp motor on a standard grinder should provide plenty of power!

thanks neil, i found an inexpensive, non-compressor, 3hp motor. i'm probably going to use 3" by 132" belts. could you take a picture of your grinders and post it?
 
Yeah a gas engine would be kind of noisy inside your shop. The fumes would be a big problem too. I kind of wonder what it would be like if the exhaust was fed outside through a pipe. Almost all of the noise is generated by the fumes coming out of the engine, so if they were fed outside through a heavy pipe you may not hear it at all, accept for what noise comes through the wall of the shop.
It probably wouldn't be real practical to have a gas or diesel grinder, unless you haven't got enough amperage in your shop.
Check out Tractor Supply Company though. they have more than just engines. You can get all kinds of fittings there, including high torque bolts and things like that. Quite a few metal working tools.hydraulic lines, cylinders,pumps.and more. check them out at www.tractorsupplyco.com

Tom,
I KNOW you would never leave paradise!! I have been there twice and it has Florida beat by a mile!!

Scotchbrite wheels and belts are just the tip of the iceburg!! The football field size stainless scrap yard is handy. MIG, TIG and plasma equipment is a must to work the the FREE "scrap"!! Having a complete machine shop with CAD/CAM technology is handy also. Plus....If I need a hand with any of my projects, my BOSS will help out!!! If you saw my mail box and the post it is on, you would laugh!! It would be the only thing standing if Lakeland got nuked

I think I have my own little paradise right here in FL!!!
