Hi,
Looking to replace my old disk sander. Would anyone recommend the Micromark 10-inch-disk-sander? I'd like something that runs smooth and quiet, a tool that is a pleasure to use. The Micromark runs 280-480 rpm.

Thanks in advance,
Ross
 
Have a look at a Neilsen magnet disc in 8" size. You can cut your own sandpaper from any kind you want and have as many sizes on as many discs as you want or buy the precut discs for it. Mine is variable speed, reversing but of course you can buy just the hub and as many discs as you want to mount to a motor of your choice with the correct shaft size. Simply said this is a super machine with top of the disc grinder quality and user qualities. Frank
 
Wow, what a machine, just an awesome piece of equipment. Kind of pricey though. One of the excellent Hawaiian knife makers got a good used surface grinder for the same amount of money. But the sg is not versatile like a disc. It would be great to get recommendations on less expensive disc sanders.

Thanks,
Ross
 
I'd recommend the Nielsen disk too. It is quick and simple to change grits, but is the Cadillac system in my opinion . . . so it is pricey.

Trugrit sells the T-92 which is nice, but may be out of your price range too at $875:

The only other way that I'd suggest you go, is to buy a disk from one of the knife supply houses, KMG, or Trugrit and then assembly your own grinder after purchasing a motor and drive. Even in this case, it would likely cost you in excess of $500.

Good luck,

Hey Mike, that T-92 sure looks nice. Variable speed, tool rest included, everything wired. I looked at the 1/3 hp model, but it's only single speed. Anybody have any other input on either of these two machines? What other nice sanders are available? I looked at the KMG...nice.

Thanks for the help,
Ross
 
Think about this. Go without the variable speed, BUT have the feature of the replacing discs rather than having to remove the grit size on the single disc to replace with another size. Frank
 
Are you grinding steel, or handle materials? If handle materials only (I don't know if it would be good with steel) I'd grab the Micromark. I want one for my work, but there are other tools higher on the list.
 
It would be for both steel tangs and handle material. The Micromark is priced right and the low rpm's seem to be just the ticket for knifemakers. But that TruGrit T-92 looks so cool! Still looking at the Neilsen magnet disc, information on work rests and/or mounting plates for this motor frame would be very helpful.
 
lol no problem man. I was just playing around :D Such a specific question about a specific model about a disc "sander" and "not" a disc grinder I thought was pretty crazy, especially within one day of eachother.. let my know if you find anything nice and I'll do the same bro :)

Hi Paul,

I was looking all over the internet for advice and good prices for abrasive disks. I have a 9" Sears combo sander that I'd like to upgrade. I got confused and posted in the wrong forum. I should have searched before I posted.

I purchased the T-92 from Tru-Grit a few years ago, I used my own motor which is the Baldor 1/2hp 1140 rpm, I haven't had any problems using it, mostly for wood and bolster material.
 
Disk grinder wish list:

The abrasives-r-us guys have a good product offering, because they are filling a market void.

It seems that most of the other commercially available disk grinders are a bit underpowered to be used for both steel and wood materials. . . especially hogging out metal to profile blades. A disk grinder can be a very viable piece of equipment, especially if it has the power to perform heavy duty hogging operations and has a built in work rest. It can spare you from wasting your expensive 2x72 belts for rough grinding, and preserve the 2x72 belts for the more delicate or precise initial plunge grinding or finishing jobs.

I've struggled with the fact that all of the marketed grinding disks are sized for shafts to fit 1 HP motors. I wish options for a 2 HP (3/4 or 7/8 inch) motor shaft size were available.

In short, I think there is an opportunity for someone to market a reasonably priced 2 HP variable speed, 9 inch disk grinder system with a work-rest tilt table much like the KMG or Tru-grit offerings. The ability to adapt the the Nielsen Disk system would seal the deal.

As has been stated before, there are 56 frame 2hp motors that have a 5/8" shaft. So your problem is solved. This would require a vfd that can run a 2 hp motor and this requires 220v input.

OK . . . I admit that I overlooked that reply and link in the other thread. That does solve a lot of questions for me. Granted, most 2 hp motors don't have a 5/8" shaft, and I didn't find any when I was searching. With that said, thanks for pointing this out.

I now realize that my previous statement that the commercially available disks will not fit 2 hp motors is not correct.

Also, I apologize the OP because I've moved the discussion away from the original question.

Thanks,

Mike L.
