Mine is only a small Emco Lathe, an Emco Compact 8

I have a few HSS / Brazed bits, but they need touching up.

I did notice the Chinese inserts on EBay, they look just like the ones I used to get from the jumble - might try some of those.

Perhaps I am trying to be too clever by looking for inserts for various materials when the Chinese ones might do the job.
