If it’s a S7 mine are pressed in and would think that the pins are shouldered. Looking from the back it looks like there is a large dia bush with a smaller dia pin in the centre. I’ll have a go at pressing one out and see what it’s all about as I don’t use this bit anymore.

That’s really nice Dave.

Problem with the hem speed increaser is its reverse rotation, but I have some half finished drawings for one that travels in the right direction, watch this space!!

18 mm mdf sheet and coat with rouge as a finishing.Or you could try 3M micro polishing sheets.

I was always under the impression that grease used for bronze bearings is a bit special as the additives in a lot of standard greases can attack bronze.

Even with your Taper turning att fitted could you not fit the dro extrusion on stand offs?

Isn’t there a Model Wheelwrights Association?

Could you fit a elf powered drill head to the Bridgeport that way you still have X and Y movement?

You could try hardening a couple of pieces of EN8

This is tape and reader head fitment on my lathe

Why can't you silver solder the holes up and start again??

My MDRO kit on my S7 is fitted to the taper turning fixtures on the back of the bed and has not given any cause for concern since it was fitted in May 2017. I also buried the mag tape in the crosslide and buried the reader head in the saddle, a really worthwhile exercise.

Thank goodness for that!!!

Hopper the depth stop bar on the original has a flat machined all along it, so it moves freely in the hole regardless of burrs raised by the screw.

Seems like they have disappeared for good RIP

If you do intend to regrind your jaws look up the article in MEW that gives instruction on how to make a petal; plate. Its brilliant and I have since reground 6 chucks with it and the results are superb not only improving grip but concentricity as well.

I don't really understand about the distortion being blamed on the silver solder, I do quite a bit of silver soldering and have not come across this. Your choice of material may be part of your problem as straight after soldering it would be fully annealed and given the gauge and the cut out I would imagine it would be prone to be easily damaged.

A little bit on this on Homemade tools.net today

Im with NDIY its not the size its the fit!

Unfortunately Bass you can get rid of it but it will reappear a short while later. The thrust bearing mod mentioned earlier is a good start as when fitted the play you then have is definitely screw or nut. But as you usually travel in one direction is it really that much of a problem?
