Which one?

[barb.j.enders]

As I mentioned in a different post, I received the Flex Drum sanding kit for Christmas.  I need to purchase the grinder/motor for it.  I plan to put the MacMop on one side and the flex drum spindle on the other side.  I was planning to purchase the King low-speed bench grinder but the store that has it also has a low-speed, long shaft buffer.  Which one would work better?

Barb, I just wanted to tell you buying just a grinder for what want is not as easy as it seems.  I did many months ago, thinking I would just buy a chuck for each side of the grinder and attach the sanders to it using the chuck... Well I am still searching.  They just do not make them.  They have what I have a picture of, but they do not work.  They do not fit far enough on the grinder shaft, so you have to allen screws tightening on the threads on the grinder shaft.  Which makes the chuck wobble so badly it is unusable.  So so far, I have a nice grinder that is not useable for what I wanted it to be.  I could cut the threads off the grinder shaft. But then I have  made the grinder totally useless it that does not fix the problem.  So the answer is to but an expensice Guinevere setup which is high speed which I think is too fast.  If you do buy one and find a chuck that works. Please let know.  @Dave Monk went the same route as I was trying to and ended up having to have something made at a machine shop which was pretty expensive.

If you have or can purchase a cheap small lathe you can fit a keyless chuck from dead battery drill and you can drive sanding mops or what have in it.I have one set up and use with all Guinevere sanders.

The adapter cost me $100 to have made. I used the chuck off of the adapter that I bought that was like yours that did not work.

I set up a buffer for sanding.  I like having the extra room from the longer shaft on the buffer compared to the grinder.  I also had to have an adapter to fit a chuck on the buffer, which is pricey, but I ordered it from McMaster-Carr, and it was less than $100.  The buffer is 1750 rpm, which is fast enough without being too aggressive, in my opinion.

One option I use is a flex shaft that fits in the Jacob's chuck.  This lets me use Rotary tool bits for detail work, without needing to run a noisy Dremel tool.  It also holds my sanding mop, so I can lay my work flat for support while sanding off fuzzies.

I would go for the buffer provided it is also slow-speed at 1800 rpm or less.

I think that 1800 is still to fast. I run my sanding mop and Mac Mops on a drill press so I can slow it down.
