I use APT tools, worth a look!.

Having done that once I now change my tips over a tobacco tin lid or similar.

Indexable isn't the same as interchangeable, but saying that inserts of the same shape, dimensions etc, etc will be  interchangeable within the tolerance of the insert manufacture.

I think exactly the same as Clive, not worth a lot and not very useful, but who knows.

Nothing wrong with Bridgeport's, I made my living on them for many years, super versatile machine, I wish I had one in my garage!.

Tony

I couldn’t agree more, let’s have your suggestions!

Fascinating post which I am following with interest, from my own experience owning & using British iron both in industry & as a hobby, rebuilding a Myford 7 and now with a 3 year old Warco, I would retire the old lathes and start afresh with new gear unless the OP wants a load of grief trying to resurrect 70 year old machines. No right or wrong answer to this problem.

I built a DW years ago and a picture would 'paint a thousand words', having said that i am guessing the same as Bill from peak4, I used my tapped boss for holding on a belt guard so maybe that is the purpose of the flat faced knob.

There are online calculators just for this purpose.

Looks like you can get some hexagon and square ER collets in the USA from 'Maritool'.

Tony

If you put '5C collets' in the keyword search box [top left of this page] you will see there are answers to your very question

Tony

I have a 290V but the older flange type, I use a ER 40 collet system and recommend it wholeheartedly.

Or use a drill chuck.

Tony

Oh the service was good but the drills themselves were not!

Tony

I would go for a Warco VMC turret mill, IF it will fit?

Tony

I have stopped buying from them also as the drill point grinding was atrocious! I can re grind the points myself but under say 4mm my eyes aren’t up to it.

Agreed, a vernier caliper doesn't need batteries but a certain degree of skill is required to read it and a digital caliper does need batteries.

Paul, you need to get immersed in mechanical engineering, reading books and watching videos, the latter is slightly dodgy as their are some shall we say inept people posting on Youtube etc, you will soon pick up knowledge as you go along. One tip to start with, PCD is pitch circle diameter.
