For the most part most of it is stuff that was going to be recycled, paid $10 for the base and the rest was junk that was free. Had the 2 wheels laying around, they are rated for 3 tons which is more than I'll ever put on them. Considering I am broke as a joke (and not a funny one) it came together rather well, works like a champ. Lesson 1780 rpm 2 hp motor that I bought years ago is overkill a little but it is all I have. Staggered the top wheel forwards slightly and as a result I was able to put the angle on a knife very quickly without really having to pay real close attention to what I was doing. It took moving everything around quite a bit to get the angle but it is right where I want it. Platen is tipped forward to match also.
Not a quick change belt set up but not that bad either, just have to remove one bolt. Wheels are off a portable industrial conveyor that I scrapped at a place I used to work. I always keep wheels when I am told throw it out lol.

Got a free bandsaw too. Was converted to a standing one and it needs work, likes to throw the blade but for free I could not pass on it.

Yes bottom wheel is the same as the top, they are 6X2. Bottom one is mounted on the motor shaft is the only difference from the top.
 
There have been some interesting alternative grinders on here recently, and I have to hand it to you guys for your ingenuity. I hobbled along on a Craftsman 4x36 until it quit before finally buying a Coote.
 
That's great! I'm telling ya, knifemakers are probably the most innovative people out there next to maybe rocket scientists.
 
If you get a few 48 belts- just add an idler/tensioning wheel to the back for the extra- you could potentially use 36 or 48 belts- Wonderful ingenuity... I am excited to see what comes off that machine...
 
Been playing with the band saw and it really does not need that much work, got it to stop throwing the blade. Everything that could be out of line was, put them where they are supposed to be and works well enough with a few quick adjustments that I just cut my first set of scales on it. Alfezia is some pretty dense wood, cuts fairly easy though.
 
That grinder looks great! The only thing I would worry about would be what the wheels speed rating is... wouldnt want them to fly apart.
Cool grinder...........:thumbup:

Howdy Montana Guy, we must be related, I am poor also! Great job! If you would like to have variable speed with one lever, you can use an belt clutch off an treadmill, mine works great. The clutch looks like a small snowmobile clutch and is tightened or loosed with a lever rather than motor rpm. Would be happy to corraberate with. Some pics. If you like. Keep up the great work.
 
Thanks for all the ideas on this, I am planning on building a 72" once I get back to work so this one will probably stay this way. I remember the treadmill thread, that idea is genius. Thanks for the concern also Mace. I know these wheels well, I have used them in the past for other applications and they seem to be bullet proof. If I had any doubts about them they would not be on it. I have used them to drive a 15,000 rpm machine with the center cut out to hold a belt because the pulley broke, worked like a champ for over 2 weeks and I still have that wheel. It is a little beat up but still intact, actually really good shape for what it went though. Jerry Rigging at its finest lol.
