I've gotten a lot of inquiries about my buddy Joe's direct drive conversion kit for the KMG grinder. Aside from a variety of benefits, here's the latest one.

Joe fabbed me up a big pair of hinges, and we mounted them to the riser blocks I use to bring the grinder to the right height for me. We drilled two new holes in the base plate, and used the existing holes at the corners, tapping them to 5/8"-13 and bolting it to the hinges this way. There's a rest on the far side of the machine that one of the grinder's uprights sits on when it's horizontal.
 
Looks like a simple, but very functional solution. Seems very easy to move back and forth as well, unlike some of the other "base hinge" designs I've seen on other grinders. Nicely done!
 
Do you lock it in anyway or find the weight sufficient?
 
Right now, it's just under its own weight. It it becomes a problem, which I highly doubt, I'll do something about it.
 
Pretty slick. Mine has a clamp mostly because I dicked up the slot length and it's not level at it's resting point 😂
 
Matthew, that's a cool set-up. I might want to try that. Tell me, what supports the grinder in the horizontal position? Does it rest on the motor?

If you look really closely in the beginning of the video, you'll see a post on the left side of the grinder - the rear upright of the grinder rests on that post. The motor never comes in contact with anything. Hope that makes sense.

yeah, I see now and also see you pointed that out in your original post. I've never been a member of the total awareness club.

Thanks!
 
That is a really nice grinder tilt. You have mastered that grinder for sure! Good work! Larry
 
Neat mod!!
I'd be just maybe afraid it would try to "climb" up on the blade, in vertical mode, if not locked down...at least in theory

C'mon, stezann... didn't you see the video? Look at my arms!!! Do you really think I've got enough strength to develop the forces required to give that wheel traction? :D


This is the last chance for this machine. If this modification doesn't manage to make me happy with it, it's gone. I've spent way too much time correcting the flaws in this design, and also correcting mistakes that were let go by whatever Beaumont considers QC. At this point, this machine can hardly be considered a KMG, and I've done just about all I can to it, and it's still not perfect. There's just so much you can do to a pile of crummy cold-rolled stock that isn't even squared up or straightened before it's used, and there's no hope in correcting holes that weren't drill right to begin with. I wince every time I hear someone say they bought one of these recently, especially in light of the vastly superior machines that are available from so many other companies - companies that even offer customer service AFTER the sale. Go figure!
 
QOTSA is better, of course.

;)

Btw, the high speed part of the video was just under 5,000 sfpm. According to the Norton Abrasives engineer I spoke with, this is the range you're supposed to be using their coarse ceramic belts at with our steels and hand pressure. :thumbup:

nice, hard to tell what sounds better QOTSA or the grinder.
