from the names I would guess he is norwegian , so yes its close to me
its a pity to see how he used that stainless tank , could have been a high quality still
but I love to see that he use an old boiler burner as the heating source
its the most economical way to heat a furnace
you can run it on diesel , kerosene , frying oil or almost anything thats combustable
if its brass or bronze is impossible to tell
today there are so many "bronze" qualities, many of them doesnt contain any tin
just to be sure I have always mixed my own stuff
ok the classic 90/10 isnt the strogest of them , but at least I know that Im historical correct and got an alloy that been used for cannons in approximately 600 years
there are lots of evidence for old cast iron cannons that burst when fired , but I havent soo far found any historical evidence for that happening on a bronze cannon with a service load
the cast iron cannons had a wall thickness of 1,25 to 1,5 times the chamber diameter
it didnt help , some of them burst anyway
so I feel secure enough with the 90/10 alloy
I would never use some alloy that I dont know what it is for a barrel casting
