This is a project that really is far down on the tuit list but the lathe project has changed the priorities a bit.
I needed some 3/16 BSW bolts with partially countersunk slot heads.?????
So some ali bar stock 1 1/4 I think

This cut consentric and faced of drilled for the revolving centre and knurled (I still want to mod that knurler and make 2 more)

A bit of profiling to make it look a bit friendlier.
After boring the resses for the die a test fit nice and snug.

Then I drilled and bored and reamed the centre hole to a depth that would be trough after parting.

Then I parted and faced the other side with some leather to protect the knurlling

And the semi final part

The first 3/16 BSW bolt

Note that there is only one grub screw that is because this is going to be a die holder-holder not a die holder the plan is to make small holders that fit into this part for all the small taps and dies (they will all be set up already for swopping over.
The 1 inch dies will get a holder holder that has 4 handles at 90 deg etc.
