Just google wheel dressing star wheels there are several choices

For your indexing could you not use a finger a la clarkson?

Sorry to disagree but it’s called box hardening and brown paper is put in first

Surely the gunsmiths do browning

Clockmakers still blue their screws the same way as always by heating the screws whilst laying in a bed of brass swarf ( heated underneath) until they turn blue then quench in oil. Alternatively you can black your parts chemically, just google blackit solution.

Usually if its a 1/2' head that's the max size thread dia, although in later years oversize sets were available.

Best of luck Chris your problems are only just starting, wait till you start collecting die sets,I hate to think how much I spent. Good thing to make for them is the internal stop which is a must when making batches of Bolt/Screws. I have just made a batch of 5mm sq headed bolts and they were threaded at 300rpm and the head clicks off at the came place every time,Magic. Thoroughly recommend the book Rob mentioned.

Same as Peter not had mine yet, could it be anything to do with alphabetical order?

Just to chuck my pennyworth in it doesn't look as if you have gone deep enough, as your wheels look fairly coarse.

Didn't a lot of capstans use lever feed cut off slides?

10 square headed QCTP holder bolts today for two new toolholders.

I like the idea of the resetable handles Peter.

Could be an interesting project, but I am amazed at how they do it for the price ,that is if its made in Austria.

My mill uses a redundant wiper motor with home built speed control.

Taig toolpost dimensions are, front 1” sq and 1” from base to bottom. Of tool slot, tool slot 0.375” wide total height 1.750”. Rear toolpost is 1” sq, 1.236” from base to bottom of slot, 0.375” for slot withe total height of 2.00”. They also do a rear toolpost for parting off which is made from steel (the others from hard anodised aluminium) The parting version is much beefier and has the slot at an angle a la GHT and I find it works very well, I also use a small QCTP on one of my machines

Could you put your 3mm pin through the hole (just long enough) then slide a collar over the pin?

Hi Kiwi Bloke yes I have a set of those, got them from a RAF Tech about 30 years ago. Mine are bakelite and the headband is now replaced with a Halcyon goggles headband, the fore head piece is not covered the bakelite goes straight to your forehead. I do now use an Optivisor and it's difficult to tell the difference in optical quality it's just that the comfort is better with the Optivisor. I do occasionally walk past the building where they were made as I am a Norfolk Boy.

You would have thought that the idler pulley was the one to move but the pulleys all look as if they are in a straight line which means moving the motor, or could it possibly be that at sometime in its history it has had shorter belts fitted?

I use 20 dip wheels for my hobbling machine and store them in this box small at the front 16t and large at the back 127t , it has a sloping hinged lid to keep them clean. Sorry about the upside down photo.

Is there any chance you could silver solder the two halves together for now to finish your job then the mill is available to make new ones???
