Bobalu, if you're 15, you should have some sort of income. Why would you even ask your parents to buy propane for you when you could buy 400g for yourself for less than half an hour's wages?

As for safety: as in any worthwhile endeavour, true safety lies not in safety factors on the construction, but in being as far away as is humanly possible :wink:

Google is your friend.

Plans and information.

Stainless is not necessary for prototyping. Use exhaust pipe.

here in the uk you can pick up a cheep stick welder for about 40 quid new

if you dont need alot of welding you could use car battery's
produced a nice weld i used 3 battery's to make 36volts and used a bit of coat hanger wire as a resistor to limit the amps bit getto but it worked
be realy carfull if you try it battery's produce hydrogen

you do have a good point, I think Ill just stick with trying to find some one who can either weld the major parts together, or just seeing if one of my dads friends will let me use his metal shop
