    Newby 2x72in. belt grinder

    Im thinking that maybe i should gust go with a vfd, 3 phase, direct drive, 1700 rpm motor till i can afford a 3600rpm one with an 8 inch wheel. Ive never been the start out small and continuously upgrade sort of person. Better to just save up and do it right.

    So you simply stretched the belt around to change speeds

    Would anyone mind sending me a picture of a step pulley setup. I know what they are and I know basically how they work but I'm not entirely sure how you would hook up the tension system thanks

    So if i put a 3hp 3400 rpm single phase motor and simply change drive wheel sizes to attain different speeds. It's certainly not as simple as turning down a dial but I would not get The loss of Power from using a rheostat.

    Thsts why i left myself room to play with the table. I think i am going to direct drive my 3hp motor behind the grinder. After i build the motor mount i just need to get a vfd. I think this option leaves less links in the chain to break so to speak...

    If i direct drive a 1700rpm 6in wheel i dont think ill have a very high fpm. Thats why i geared up the speed Ive noticed they have up to 8 in drive wheels on ebay. Perhapse that on the 1700 rpm motor would work

    Luckly that is the chain and sprocket size i have. Was worried it may be too small. The motor is 1700 rpm 3 hp. So hopefully that evens out

    If i switch to direct drive with a harbor freight motor it would go up top. Would enclose the motor on top with a filtered enclosure. I suppose it could be vented from the bottom too

    The motors i have are fully enclosed. I had not thought about vibration though, much less how fast that chain will be running. Time will tell. I would have preferred direct drive however i would have to buy a new motor. My budget is a bit tight. I liked this idia because i can gear it up or down as i wish. I had thought of getting a harbor freight 3600rpm compressor motor but they arent enclosed. Would just build a filtered vented enclosure for it and get the extra warranty. Lol
  13. Ok so i am posting this for suggestions, a little constructive criticism, and to avoid any costly mistakes. I purchased my grinder from thebeltgrinder. the grinder seemed to be built solid and easily adjustable and modifiable. I have 3 3hp 1700rpm 3 phase 240v motors i got that work was trashing due to a gearbox upgrade. I realize these are not the most idial for this application but they were free. I plan on running a 240 out to my garage. Once that is done i can use a vfd to power the motors. The motor will be mounted on the bottom deck and has a 32 tooth sprocket. The chain will come up through the table around a 15 tooth gear, 5/8 shaft with 2 saddle bearings. This will go to a 4in drive wheel. The saddle bearings will be raised up on blocks to afford the velt drive wheels some room. The gearing should about double the motor speed of 1700rpm to approx 3400rpm. There will also have a sheet of stainless or aluminum for both upper and lower table tops.

    Another newbie forge build

    I do think the opening may be too small due to the fact that the burners seem to be pulsing. The burners no longer heat up though and seem to be burning down inside just fine. I do plan on maybe doming the top of the opening so that I may get other things in and have a little more room. I've only been running it for 5 to 10 minutes at a time to bake out any excess water.

    Another newbie forge build

    About two or three hours after this video I went out and relit it. This time the burner seem to be functioning much better. They're burning down inside the forge very clearly. And the burners don't seem to be smoking nearly as much. I'll play around with it a little bit more later today. And I will get some pictures
