I got the paint off. I use wire wheel in the drill. Gets the teeth clean. These ones in good condition. Just got two more to do .

Hum the Drummond lists 130 tpi and 160 tpi (from memory) as the fine feeds which is ( a very approximate ) 5.2 and 6.4 tp mm or 0.19 and 0.15 mm per rev if I have worked it out correctly. Which would fit in with your 0.15 mm/rev and co incidentally does give a nice finish with a .2mm rad insert on a one or two inch diameter bit of steel be it EN1 or silver steel does not seem to matter.
That would be at about 500 or 700 rpm I have not worked out the gearing yet as it is a non Drummond lay shaft and the ratios of the lay shaft pulleys do not match those on the spindle.

It is actually 110 and 174 tpi for the fine feeds, I checked this afternoon.

I did finish off my change gears .only a few missing. Will hopefully pick them up on my travels . Also cleaned the external jaws for the chuck. And had the jaws out to see how far I can go with them before contact . Looks cool with the jaws right out.

Bit late now but a wire wheel on a bench grinder is the way to clean changewheels, very quick.

The chuck looks like something from a Blade film

But would you want to use it like that? The jaws must be half way off the scroll.

Seeing your progress makes me think that I really ought get cracking on with my M type again.

They can go more. I was just looking at how far before contact. The chuck is roughly 5 1/2 inches in diameter and that's a good size. I wouldn't use em right out.

I need a new wire wheel for my bench grinder. So had to resort to the hand drill wire wheels

I trying Matt. But not on my ball game at the moment as not very well. These antibiotics make me feel a bit crud.

Have an old Hitachi angle drill. Perfect for wire brushes. About the only thing I use it for these days.
Speed control and a proper on off switch. Bit unwieldy In a standard drill.

Not many grinders come with speed control. My old Bosch did but the new one doesn't have.

Na
Angle drill.
Mines about a decade older and still going strong.

You're still well outdoing me on progress. I really need to get myself motivated. I've done practically sod all in the shed for ages now.

Come on Matt. It's hard to get motivated at times I no. But once you get past it all be good.

@spencer 427 What's the internal bore and DP on those gears? I have a set languishing here which I bought back when I had the old R&A lathe. They don't fit the ML7 so I'm planning the 'Bay for them as soon as I get one of those famous 'roundtoit's

In fact I mentioned them on here a while back but no-one seemed interested.

I'm pretty sure from memory mine are 26, so that might save you the trouble......

Today I trued up the Taylor chuck . I noticed a lot of wobble before that made turning long stock a pain. Put a dti against the backplate .miles out. So got brave and faced it flat. Cleaned up and seated the chuck. Miles better. Even with a long piece of stock there is hardly any wobble. Can't get much better than that. I no the stock isn't supported but my objective was to get it running almost with no wobble .job done. Now just got clean up the awful cast dust.

I bally well hope so.

Today I will be starting the machining of the backplate for the collet chuck.
