I had a similar problem - milling slide no nuts. I turned a set of nuts on a threaded mandrel; rectangular foot but circular tapped pillar. My slots are about the same size as yours.

Re: T-Slot nuts for Hercus milling attachment
I can get 16mm square bar in 1020 or S1214. Does anyone know which is better for bolts?

Thanks Mike, but I bought a length of 16x16 1020 today, so I'm going to have a crack at making some 3/8" T-bolts over the weekend.

Made a couple of bolts this arvo. They came out pretty well. I'll make some more tomorrow while I'm on a roll.

They look sweet!
As far as milling on the lathe and the ER40 collet goes, I'd have to say that it will hold the cutter more rigidly than the other options mentioned as it will keep the cutter closer to the bearings. The further away, the more any bearing movement gets multiplied.1915 17"x50" LeBlond heavy duty Lathe, 24" Queen city shaper, 1970's G Vernier FV.3.TO Universal Mill, 1958 Blohm HFS 6 surface grinder, 1942 Rivett 715 Lathe, 14"x40" Antrac Lathe, Startrite H225 Bandsaw, 1949 Hercus Camelback Drill press, 1947 Holbrook C10 Lathe.

I briefly tried a bit of milling today with a P&N 4 flute end mill held in the 3 jaw chuck. I got a bit ambitious with the depth of cut and the end mill walked out of the chuck about 2mm over the length of the cut. Hopefully you are right Ewan and the ER40 will overcome this problem. I ordered an ER40 collet chuck on eBay yesterday.

You will need to make a drawbar for that. You did order one with a thread for a drawbar right?
