Some better angle shots would be most helpful George, for example face-on with the camera about 4 feet away at a height between the top and bottom shaft. Handle end and working end. That would show the relationship of the various workings quite well. Your first view of the extra pics would be pretty good if the camera wasnt held so high. You know, until the pic with the guys hand on the top adjuster even the scale was difficult to tell. I thought it was a floor-standing item.

How to spoil the cross slide of a Myford by letting the dieholder handles strike the machined surfaces,not the way I was trained to do a job like that. In my working days a batch of a hundred or more alloy knobs would be polished on an old lathe, previously they had been turned to a good finish, a "flat" file would be used ,this was a file with the usual wooden handle,all the file teeth had been ground off on a surface grinder,one could easily be made from a length of BMS, the handle is essenti...

John, There are abrasives and abrasives, Use depends on the duty. Look up the Mhos scale. Talc is not particularly abrasive, but diamond will scratch everything else. The Mhos scale refers mainly to minerals, but put simply one requires a harder material to abrade any object. The mild corrosion on tooling will have a different hardness and so may well be abraded by a mineral which will not abrade the steel. It’s why scotchbrite is used to polish up a finish rather than grinding away the ...

Ive had a CK Parallel-Grip Perfect for many years which does have true parallel jaw movement but only a sliding sleeve to set size relying on friction to hold it in place. Grip is decent but not as good as the real thing. Appears to be discontinued. The Stahlwille 65622250 in the misterworker link from DC31k has the same pivot geometry so should be properly parallel. Geodore do a similar one as type 137 P with, apparently the same pivot arrangment. Looks to be a bit more expensive than the Stah...

Fastenings are not so difficult. Most wont be far off the 3.5 / 5 ratio, though youd probably want to use screws with size-smaller heads in many areas for appearance or accessibility - a spanner takes up a lot of room! A rough guide to the right area is to assess the nut and bolt sizes in full size, and bear in mind they had to be manipulated by blokes with spanners. Looking at preserved machinery, a lot of the ordinary fastenings were no more than perhaps 3/4 diameter; much above an inch was ...

When I got a Myford quick release collet chuck for my S7 Mk1 it also came missing the clevis, its a simple thing to make assuming you have access to a milling machine, if not you could even hacksaw the clevis cutout, no particular accuracy is required, it only works for a few seconds to open or close the collet, the rest of the time it just sits there, for the clevis pin itself I just drop a m6 bolt through the hole. Ive got to go out now but if you want Ill try and put up a photo of it later a...
