making tin cups, having problem


Recommended Posts

I've been doing a little blacksmithing, but now I'm trying my hand at tinsmithing.
I need to make about 8 coffee cups for my chuckwagon. Problem is everytime I cut my bottom out and try to bend the edge over a round mandrel I keep getting little points where the tin won't fatten out. I live in Houston, Texas (mnray@aol.com) Any suggestions?:(

If you have a lathe you can spin a bottom over a form in seconds. I have been playing with tinsmithing for a while and I know your problem with pounding one out. Cut a 1/4" steel form and drill a hole in the middle, weld a
pin in so that its flush and you can mount it in the lathe. Make another plate to press against the first one with the tail stock. Clamp your tin bottom blank between the two plates and I use an old VW lug wrench with a smooth round end to spin the edge right over. A little grease on the end helps.
