Converting a cheap grinder into a buffer
I usually use a electric drill with a buffer attached when I have buff, this is actually working fine, but I have for years dreamed of a bench version, just thought they were too expensive or cheap and with no power…
I had one of these, that ended up never used after I got a water grinder and a disc sander.
So a conversion was obvious.
I bought the spindles on E-bay for next to nothing, one left and one right twisted, split the machine apart, actually this was a couple of years ago, but as I wanted to mount them, I found out the one axle was much thicker and so the spindle could not fit… and I could not get a spindle in a fitting dimension, then a lot happened, I packed the grinder away and time went.
The other day I found the grinder in a box and set up to solve the problem, with no plan and a hack saw…
First I cut the right sized axle to length, this was easy, just made the motor run and put the hack saw on it.
Then it was just to screw the spindle on and put on a buffer.
Here we had the problem…
I tried to grind of with a hack saw but the blades just burned away…
Then I remembered I bought some hard tips for a lathe chisel with replaceable tips (another unfinished project).
Hmmmmmm could that be possible…
So I clamped a tip in a pliers and made a simple rest.
This worked amazingly well, I just had to be careful not to over heat the axle.
In a few moments the job was done and the axle had the right dimension.
So I just needed to screw the second spindle on and make it run.
This rocks, I finally have a buffer, this will come in handy.
Hope this can inspire others to just go for it, when it seems not possible.
