Proxxon Disc Sander

[Roger Pellett]

I recently decided to replace Screaming Mimi my 4” Jarmac disc sander. With a fixed speed of 7000RPM it was too noisy and often burnt what I was trying to sand.

The Sander built by Byrnes Model Machines is of course the ultimate but is out of production and used units if they can be found cost more than I wanted to spend. I then looked locally for a replacement but all that I found were single speed machines turning faster than I wanted.

Based on favorable reviews on Amazon I bought Proxxon 125e Disc Sander. Photo below. Although the machine plugs into a standard 110v domestic household outlet, it is powered by a 12v DC motor. DC motors do not lose torque at low RPMs like an AC motor. Internal electronics convert 110v AC to 12v DC. For European buyers a 240 volt version is available.

This well made machine hums instead of screams and is balanced so it doesn’t try to march across the workbench like my Jarmac did. The table can be tilted and a pair of knobs make securing easy. A well made miter gage rides in a T track.

Selling a close to $200 US this is a good choice modelers wanting a variable speed medium priced stationary disc sander.

I've got the same, working fine. I usually use it in the low rpm range. My only comment is that it is hellishly expensive, as with all Proxxon gear.

I believe that you have more options with that DC motor.
A variable voltage DC converter - alligator clips at the motor - will not only allow for lower RPM but if the red and black are reversed - you can get CCW rotation?

I have a 1.5V to 12V converter - probably low for your machine - but it allows for the above on the little DC motors that I bought. It even had that useless free mini drill that HF used to give away doing actual work. The 1/5-1/4 size Dremel type hand drill.

If Janos can get low RPM - I guess that Proxxon already has those options?

Best disk sander I use since 2019. It has variable speed.

I have a Proxxon disk sander and have been impressed by it, It is my second most used power tool (next to my $12 nail drill) It is well made, quiet and does exactly what it is suppose to do.

This is a similar sander for a very cheap price that works great. Variable speed. They sell at Menards

Looks identical to the one Micromark sells for $145. Showing out of stock.
Looks like perfect clone of the one on Amazon.
I have one that looks like that, but I don't remember where I bought it. It really works well.

Full disclosure. The Proxxon machine is made in China too. From what I’ve read, while there may be no difference in the machines, there can be a difference in the QC of the companies that put their name on them. I looked at machines sold by Menards, both at one of their stores and online and somehow missed the one posted here.
