I will be getting an edge sander. Here are my choices…

A new 1 & 1/2 hp 110V or 220V (convertable) General International 6×89 model for about $1000.

A new Ritter 6×108” 220V 2 hp for about $2300.


A used PMC – 152 sander that has a 3 hp motor but it is 3ph…price is $500 but I will have to pay to either change the motor to one that I can use on a 110V or 220V circuit OR get a phase converter. I don’t know how well this conversion would be. This sander hasn’t been used in about 10 years or so. Last time it was used it “worked perfect” according to the seller, but I can’t check it as they no longer have a 3 ph power supply.

Any advice? I will be using it when making my bows…which I would consider to be moderate work, but I would like whichever unit I choose to last a long time.

My personal thoughts are just go with the used one and by a converter, it will save you money in the long run. also offer them less money for it because you cant see it under power.

You could get by with a 3hp rotary converter for a few hundred dollars. But if you consider getting a rotary converter I would recommend min 5hp for future 3ph deals.

Last summer I was on the look out for a edge sander and found one on Craigslist, it came out of a printer shop and came with about 50 belts for $150. It wasn’t exactly what I was looking for but for that price I couldn’t pass it up.

To say I know anything about a 1 to 3 phase converter is an overstatement…as I am NOT familiar with them at all and have no idea of the cost for such thing. That is one of the main reasons I joined this forum. I absolutely need to have another sander here next week to finish up some work.

The one that’s been sitting may need bearings. Just a thought.

I have had a previous Ritter product—dowel borer—and it was a workhorse. I have had a Ritter 4×132 edge sander for about 20 years with zero issues. They have a different philosophy: Cast it from aluminum and cast it massive.

I am wondering if a longer platen on a sander like the 4×132 might be of more value to you (if you have the real estate upon which to site it).

Too many things about the PMC-152 made me pass on it. For one I would have to get a hook up that could cost several hundreds by the time the conversion was done just to see if the machine even worked. Additionally, I wasn’t able to get an exact quote to get the conversion done. I don’t like “whatever it takes” agreements.

I picked up a General International today.

Having been an electrician for 40 years specializing in motors and control, I would suggest you change the motor unless you anticipate getting other 3 phase equipment in the future. The most economical way to get 3 phase is to use a variable frequency drive, VFD. Any non-drive rated motor and especially with a motor that has been setting that long, it may trip the VFD on ground fault rather than start it.
