I have a small workshop, so my lathe is small and has MT1 or morse taper 1 in the headstock.   Collet blocks for this size are hard to find, as are reamers to make them from metal.

These aren't going to cope with heavy crushing loads, so be mindful if you use them in a mill or bench vise.   Consider increasing infill if you want to put the pressure on.

I wanted to store some er16 colletts but couldn't find a holder.  So I made one.
