Reply To: making a collet or sub collet

[ptheys]

Not really understanding the part about using a boring bar and reaming it. We’re talking very fine holes. My smallest boring bar is about 1/4″.I have a wide range of jewelers drill bits.I was thinking of making blank collets on my larger lathe and drilling on my moseley. First I’d like to see how sub collets will work.I’ve found some slot cutting blades at .03 thickness. For cutting I took square key stock and tapped a hole for the collet(also a brass ended set screw). The key stock bolts into my lathe tool holder.I can feed it in slow and perfect 90 deg angles.I’ve tried it using a dremel cut off disk. Now if work would quit interupting my fun I could do something.
