Hello,

I'm wonder if anyone can give me help regarding a 2MT Turning Attachment which is on sale on eBay from Myford Ltd priced £95.00. This particular tool is inserted into the tail stock, and the dead centre can be offset by 5mm.

I would like to know just how successful this tool is.

Regards

Tom

Here is a previous thread about such devices, Tom

The principle is well established [same effect as offsetting the tailstock [but without the bother of having to re-align it afterwards]

You mean this? which got a bit cheaper but is still way overpriced for something you can make yourself then never use.

Much much cheaper to get a boring head which can be used for other things, has greater resale value, has greater offset range etc

I would think he meant this … [having specifically mentioned Myford Ltd.]

But your general analysis seems sound.

Well i think the boring heads a good idea.

Usually i do morse tapers using the top slide , set a number 2mt between centre`s , dti in the tool post adjust so dti on the mt centre line then traverse and adjust top slide angle till dti holds zero on full traverse,

The top slide on the lathe is an ml7 type but its been re-worked and now has a longer slide, so can manage up to 3mt………….b

wow 101 post think id best slow down !!

In the past I have always set over the tailstock but on the latest engine I thought why risk upsetting things so tried the boring head method, made a sleeve so I could put a small Emco live ctr into the hole and had nice fine adjustment of the taper and over a larger range if needed than the Myford one offers. Hemmingway do a kit if you fancy making one though.

The boring head also takes up less horizontal space than the Myford one so less problems of it clashing with your toolpost.

It evidently works for you, Jason … But I don't think I could bring myself to hold the material in a collet and then offset the free end.

I've done something similar to the above, but lacking a small rotating centre, I ground a conical end on a broken carbide centre drill. I then mounted this in a 1/2" bar and clamped it in the boring head.
