Thanks to Camel I now know that almost all the extiguishers I have are T6061, one is T7060 and bugger me if it isnt corroded around the neck (white powder coating). Its to be set aside.Just out of interest, what's the difference in weight between the 6061 and 7060 cylinders? The 7060 might come in quite useful for other applications.
Ha! Thought you might! Here come those rear uprights! You'd better be quick though......Artie, are you using a waste oil furnace?Where do you source your crucibles?And isn't bentonite (kitty litter) a better option than oiled sand?Camel
Where do you source your crucibles?
where does the heat supply come from? and what is the operation and involvment. With all that swarf I have Im starting to brainstorm.
hey, 6061, I win I win!! What's my prize??
easy now, I may be purty but I aint no 'merican
OK so all this swarf I have, I figure I could cast a bunch of discs to machine some more hubs and or bearing retainers from. So all I need to do is make up some steel "bowls" (crucibles? not familiar with terms here)and pour into those? Should the bowls be pre heated? I still would like some details on how I can melt the stuff down easily. Is it a matter of just building a insulated "box" (furnace) and throw heat into it. What type of heat are we talking for 6061 t6?
