I was just surfing related sites when I came across this:

http://www.beaumontmetalworks.com/disks.html

Wow! Rob keeps upping the bar! I have a KMG, many attachments, and one of his disks--all are superb, as is his service. I also have a vertical disk grinder from TruGrit, which is a fine machine. But Rob's comes in with double the horsepower, a VFD controller, and a considerably lower price!

Thanks again to Rob Frink for his cutting edge products, great service, and great pricing.

Just out of curiosity, for those of you that use them, how important is variable speed on a disk grinder?

Click to expand...

In my honest opinion, variable-speed is second in consideration to how slow you can go with it. 50 rpms is nominal for anything above 320 grit. Others will argue - to be sure - but a disk sander is not really a good stock-remover, rather it is an excellent finisher-flattener. S-L-O-W....

That said, a disk and a gearmotor is a decent setup too. :)
 
I kinda want one - for cleaning up guard faces, ricassos, etc - but I do wish they were cheaper. I have an old disk that I slapped onto a 1700 rpm motor but that has been far from ideal... :(

Here's an idea for Rob - create a disk grinder attachment for the drive wheel, or a disk/drive wheel combo for the KMG1 :)
 
Wulf, that's how the Coote disc is set up. 9" aluminum machined disc that just tightens onto your contact wheel. I don't own it, but for $90 it seems like a sensible upgrade in the future (not that it helps you much). If you need to run them that slow, attach one to a bicycle wheel hub, clamp the hub in your vice, and give it a spin by hand! :D Hey, that's actually not a bad idea.... :D
 
Rob does make a great machine. I only have the KMG-1 but, it is one of the toughest, most relaible machines I've ever used. I'de recommend it to anyone.
 
Wow! Thank you, guys!

..very kind words!

The disk grinder is new. I supplied 8 of them to the Sierra Forge and Fire School in California per Mike Vagnino's specs. It was such a nice machine...and since it was already designed, programmed and tooled, I added it to the web site. I'l have them at the Bladeshow under power. So stop by and run it. I think they are very smooth! The coolest feature is that they are reversible...just flip the switch on the fly. The VFD will brake the spinning disk to a stop, then reverse direction.

A nother new item which has been long over due is and extension table for the horizontal grinder. This allows you to use 72" belts. I'll have these at Blades as well.

On the back burner, I have a few subtle changes in the works for the KMG. Currently under testing, I plan to revise the tension tracking system with the goal of adding more precision, tighter tolerances, and ease of manufacturing. I'll have more details on this in a month or so....you probably won't see these machines on the market until the fall.

And lastly, I recently came across a limited amount of 9" dia. 4140 steel from which I plan to make a one time run of steel 9" disks. I personally like the lightweight aluminum disks...but several guys have asked for the same thing in steel. I'm excited to get these in the lathe and see how they turn out. These should be ready in a month or so....after the Blade show.

We'll back to the grinding stone....the Bladeshow show is next week and I'm far from ready.

CYA there!
