mandrel for small turnings

Postby Darrell » Wed Jun 13, 2018 3:47 pm

Hi all

I am looking at turning some very small items on my lathe, about 4 inches long by 1 inch diameter.
The project is to make copies of thread spools/needle cases as found on the wreck of the Mary Rose.
Google images for "Mary Rose needle case"

I'm not keen on using a longer piece than I need so I have room for the drive rope, as half my stock would end up as waste.
So I was thinking about making a mandrel to drive the stock.
Has anyone done this sort of thing?
Got any tips or tricks or pix?

Hi Darrell, Not my area of expertise but thinking it through...you may be better off with a collet type mandrel. You'll need a uniform sized stock piece to fit it though.
This guy made one to fit a machine lathe but I cant see why the idea can't be adapted for a pole lathe. He's used what's effectively a morse taper and a wooden ring, but if you're using a known stock size you can use a straight collet, the work piece expands it slightly then a steel (Large curtain ring) clamps it by moving it towards the work piece.
