I am still considering how to get it dead accurate

If you turn a taper onto a piece of bar stock - or better still, take a skim cut on a dead (ie soft) centre - you will end up with a dead accurate indication of the true centre. Doesn't matter what the spec sheet says or even what you measured - the point you cut will be at the actual centre height. If you remove the bar or centre, you should probably re-skim it each time.

I have just looked at the photos again. Is it me? You don't even have a complete centre in the tailstock, so how do you hope to match up the tips of the 2 centres when of them is not actually available to line up?

Hi Mike,

It’s going to need the surface milled off to line them up. I have not an MT2 dead centre at present as one is on order but has not arrived.

I might be able to borrow one before i start taking more material away on Monday. The ML10 may be a known dimensions but the Drummond is not known by me. In addition this is made from a construction of the ML10 tail piece to mate onto the existing Drummond 3.5" wide bed slide. Thanks for the criticism I think http://www.model-engineer.co.uk/CuteEditor_files/images/emsmile.gif do i get dinner with that http://www.model-engineer.co.uk/CuteEditor_files/images/emsmilep.gif

Thanks Muzzer as above the actual centre is unknown

I put a ruler next to a sharper dead centre and found it was 2.75 lower this gives an eventual height for he conversion of and final height would be 15.75mm.

final drop is2.75 after removing 3mm from bottom
