JB Weld
I use it all the time. It is an epoxy putty with a high percentage of metal powder in it. I believe it can withstand up to 600F . You can machine it and drill and tap it. I have used it to make gears on small items. Use a silicone RTV to make a mould around a broken part, carefully put in JB making sure all the cogs are filled in and working quickly. Let set and pop out voila' .
