Tool post grinder

[Shox Dr]

I've got a few of these Air sanders, the clamp that holds the arm to the gun, cracks, I have welded them up: they just found other ways to kill them.
RPM is 16,000 so should be good for this

I didn't take any of the machining, all I did was mill a sallow grove for the 19x19mm bar to registor to, 3 holes for bolting it to the file, the holes in the file were placed so as to hit the webbing between the inlet and out galleries. M6 capheads were used.

Couple of pic's of it on the lathe.

Just need to find some wheels for it now

Cover everything on the lathe with damp newspaper before you start grinding or the dust will get onto the ways and slowly destroy any accuracy that you currently have. Reckon on a major clean up after the job. Those bits get everywhere!

Glad to see you have a few animals as well, I spend a lot of time trying to out think them but to no avail.
As said we have discovered \ built a idiot proof tool only to find some one has built a better Idiot

I'm not sure why I built it to be honest, as I've really no intention of using anywhere near my lathe.

because you can

I dont think that'll have the accuracy in its bearings to work as a real tpg. If you have a pott's spindle or the like you could use it to drive the spindle.
I came to the same conclusion when trying to mount a grinder on the tp, and ended up building this rig using a real grinding spindle with close tolerance bearings, driven by the nasty sloppy grinder at 10,000 rpm. Mounted in a multifix toolholder, it takes me longer to cover up the ways than mount it now

To be fair, there is no play in the bearings at all. And they aren't very big so wouldn't cost much to replace with better.

As for using it, I was considering, grinding the tailstock quill between centres, and boring out the Bushes I've just pressed in, to size. The problem I have is how do I do that when I don't have tailstock because of the refurb

 

[MrFluffy]

Price some abec class 7 angular contact bearings for it then come back and update
I'm still in crisis about the cost of ONE gamet for my surface grinder wheelhead...

Simply bearings have them for around a fiver a piece.


Now Gamet Bearings are a different league
