Any ideas on this?

I have this Myford taper attachment but the link attaching to the cross slide is missing.

It appears to be made either from a kit or fabricated a lot of time and effort has been put into making it and I would like to use it.

Can anybody suggest where I could get the plans/drawings for it to be able to make a new link?

Not an original Myford one. Maybe Hemingway?

The Hemingway Mk2 kit is modeled on the Myford original, cannot find details of the MK1.

The angle casting has a possible trademark two interlocked C's one above the other with the bottom one reversed to make the two look like an S.

This is a link from another style of taper turning attachment but the principle is the same on all of them where the cross slide lead screw is disengaged and the cut put on with the compound slide.

Sadly this one was in the acid cupboard I mentioned but it will clean up ok.

The 2 short dowels at one end locate in one of the T slots and the holes take T bolts.

The bar engages with hole in the part that slides along the rail on the taper turning attachment. A bar is used to allow some height variation as the parts are moved about. This one uses 2 dowels as a guide in the adjustment slot so that it can be adjusted and tightened without turning. These stop short of a washer under the clamp which is on top.

Further to this.

I have found a reference in the April 1987 Model Engineer of a new Hemingway taper turning attachment for the ML7.

The description is of a partly machined kit with a ground guide bar with micro screw adjustment and a machined angle bracket it could be made to fit other lathes.

Has anybody information on old Hemingway kits?

The series currently in MEW on remaking an 'official' Myford taper turning device probably has more than enough information to help you get this one working, you just need a slide to fit the bar, rather than a dovetail.

I assume this one was a kit at some point. It's a sine bar swivelling on the axis of the bearing on the left - which needn't be a bearing really.

The part that links this to the top part that fits on the cross slide is simply fork shaped and has a decent guide length along the bar to minimise rock. This part fixes to the holes and machined area myford provide on the back of the bed.

It's covered in oxidised oil in places.

Some one might be able to knock something up like this by basing it around a parallel strip but the fork is ground as well on this one.
