One of the fitters at work is a keen shooter. He knows that I have a mill with dividing head (which he doesn't) and asked whether I could make up a bolt handle for him. He's going to come back with a sketch and was talking about spiral milling...
These are just some trial pieces based on some 'net pictures. They would need to be deburred/ blasted and painted if they were to be used but you get the idea (dimensions are around 40mm high and 25mm diameter). Apparently the real trick is putting a thread on the bolt. He can sort that bit.

Making these (where the cuts have to intersect in a regular fashion) has shown me that I have slight TIR and backlash issues on my dividing head. More things to fix!
