Thanks a bit late am working on a new project to convert ML10 tail stock to Drummond 3.5" bed. This is the first idea i come up with to cut down the ML10 saddle to bolt onto the Dummond Saddle kike the old one did making a mating surface for the new MT2 tailstock.

Here i s what i started with

Here is the bottom part

Here is it cut down on image software

Here is what its going onto

I am hoping at least one of the screw holes will line up.

Still working on it

Difference from Drummond tailstock saddle to center calculation

Chuck Jaw height: 0.5845”

Tail Centre Dia: 0.1135”

Chuck Hole ½ Dia: .039/2”

Total .7175"

First cut will be .08” leaving difference from block to correct height .0825" to remove if all goes well. Does this seem right?

Some cutting down today much more to cut around 5mm to get centres same as mt1 tailpiece. Intend to take some from top and some from bottom.

Here is first try much more to cut down

First try still needs adjustment

Did a bit more to this got horizontal in the ball park and just vertical is out now . Will remove 1mm and see again

Here is the reverse showing the ML10 interface with the old Drummond saddle which was under existing tail piece.Provision has been made to retrofit the MT1 tail piece should it ever need to be. Stil have approx 2mm to remove from top was able to remove approx 3mm from bottom. Am going to take it slow here so i can get it as tight as possible 1mm at a time.

Yep Steven , thanks for the tip . I am still considering how to get it dead accurate . I need a 5/8 16 MT2 for my chuck to get the big chuck on it to hold something other than what I have . I have about 2 mm to remove approx so am going to take another 1 mm before I get into working out how to get it exact any ideas would be really helpful. Wont do this until next week.

Here is a ruler behind them in focus on the ruler then on tips

All very interesting, but are we not missing the obvious here. The centre height of an ML10 is a known dimension. So why are you messing about trying to match a centre to the centre of a set of chuck jaws, or to another centre mounted in the headstock or a chuck?

Why do you not simply assemble your tailstock, then measure the position of the centre and simply machine the base, however constructed to match the known ML10 centre height? It seems so straightforward to me, or am I missing something here? It almost feels like you are all trying to re-invent the wheel to me.

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?
