I have a set of drills I use for electronics projects that go down to 0.5mm (and SWMBO has some even smaller for her jewelery stuff) I’ve use some of mine with a Dremel @ ~25k rpm. The higher speeds make a real difference. Better in a DP though as it means work and bit can be help at same position so less chance of bit breakage.

I was given a packet of .006" micro drills that were used for drilling cornea implants ... never used as I don't have a high speed drill. Looking at them through a microscope you'd swear you're looking at a 1" drill the detail is that good. Hopefully this link showing their manufacture works. https://www.youtube.com/watch?v=G55kLhv2d_4

Moore & Wright, and others
Picked these up a few days ago. Deceased owner was a tool maker. One of the calipers has his name on it with 41 after it (year). Those 2 large calipers are 16 inch.
Pic 05a - All M&W.
Pic 54a - Pastorino Circlip pliers, Eclipse 235 toolmakers vice, other vice unmarked, could be from apprenticeship, bottom left I think is another toolmakers vice.
Pic 07a - Pipe flare, M&W Surface gauge, Rockwell chuck ball & Test Blocks 27 & 62, various clamps & engineers jacks.

Thanks Grahame
Spent 3 or so days sorting the garage out & cataloging tools, So got a good deal, seeing the family didn't want anything. It was going to be given away to friends, I said no way.
Some of the tools had some surface rust, but came up pretty good with a light touch of the Carbide scraper.
Her father was a Fitter & Turner / Tool Maker for the N.S.W Railways from 1940-85 when he retired.
I have 2 friend who are into vintage cars coming around on Wednesday to have a look at some sockets & spanners & an 8 inch Centurion (Alltools) bench grinder.

Got lucky and scored this Australian-made grinder:
As usual, working on a history page for the manufacturer. It's one heck of a unit - bigger and heavier than the 3-phase 1hp GMF I restored at the end of last year.

Hi JC,
It looks like it has decent tool rests on it, unlike the rubbish we buy today !Best Regards:

Would not surprise me if they were related to GMF. The base and tool rests look identical to a similar size and vintage GMF.
Nice looking old thing. I think they had some at Vales Pt Power station when I was workign there back in the day.

I'm having trouble dating this grinder at this point, but I know where there's a stash of Durst catalogues that will help - here's hoping I can get hold of them.
GMF came into being in 1940 and Durst 1918, for what that's worth... the only Durst ad I have found online in advertising is a very poorly scanned one in 1948 and it could be a match for what I have here, but it's darn hard to tell. Waiting on better info. Got a photo of your GMF?
I'm pretty confident at least one of the GMF grinders I have here is older than this Durst - reminds me, I need to date the Junior GMF grinder...
