I was looking for a better hammer to set work in a milling vise. Found a neat idea in the downloads section: https://www.hobby-machinist.com/resources/machine-shop-projects-for-beginners.3424/download
See pg 37
I had to change to a smaller, round head due to no large hex stock, and I adjusted a few other dimensions.
Basically it's pretty simple: set the compound to 15 degrees. Leave it set for all boring operations. 2 external tapers, 2 internal tapers, and a lead mold with a taper that matches.
In my case the mold is a piece of durabar from the scrap bin. The mold fills and releases fine as long as it's hot enough (pre heat). The Internal taper locks it in once set so a light whack takes the mold off.
It doesn't use much lead, is easy to recast, and has a nice "dead" blow to it. Despite massive chatter taper turning the handle and horrible knurling it turned out fair and will be a useful tool.
