These have been on my list for a while. A small hammer from scrap, steel head and aloy bar handle it has a bit of weight but a nice balance, I don't know where the shape came from it just kind of eveolved but I've likely seen it somewhere.
My little lathe has a small 3/16" die holder but most of my dies are larger 1" and 25mm, and I can buy one from them but baulked at the £43 + VAT + postage so a bit of brass bar and suitable tube, a bit of turning to fit then soldering, drilling, tapping and it works. It has to slide on the tailstock spindle which is 1/2" so bored out to that and I can also use it in a chuck on the wood drill by utilising a 1/2" transfer punch.
Functional not fancy and at no cost.
