Anyone here use induction heaters? I made one that can melt aluminum pretty effortlessly, but can't quite make it with copper yet. I think some better insulation will be enough to make it work. Also, I expect that switching to a steel crucible would reach higher temperatures than the graphite one I'm using now.>>2841928
I reccomend making carbon foam for your insulation shits light weight than most materials wrap a loaf of bread in tinfoil and chuck it into a wood fire in a few hours should have a pyrolysis loaf of bread aka carbon foam with a smooth skin
upgrade your insulation to the space age.>>2842050
>Flammable non-refractory insulation
No.>>2841928
going to ask a power-hammer/forging question, hopefully people here might have used one
i want to try DIY drop-forging, using some dies i have the capacity to mill. it wouldn't be fully closed-die forging, the dies wouldn't 100% meet and would allow flashing to be pushed out the sides. do common power hammers (the Little Giants of 25, 50, 100 pound hammer weights, and the homemade tire/treadle hammers) have the x-y repeatability to do this semi-closed die forging? my understanding of the difference between drop hammers and power hammers is that the former is mostly closed die, the latter open die, and open die inherently needs less repeatability on where the top die hits the bottom die. the LG hammers also have a very short vertical guide for the hammer to follow, whereas drop hammers have very long guides. this seems like it would lead to less accuracy on the LG power hammers than on a dedicated drop hammer. do i need to build my own shitty drop hammer or will a power hammer do?>>2841999
