I'm in Hobart. I'm looking at the BT7000 sunbeam oven, as I think you said it was the one. Top and bottom elements with fan force so should fill the needs. I'll keep my eye out for a large oven but don't care which as I just want to get the right one first. After speaking with HI-TEK,who was great in explaining stuff it appears that if you follow some simple steps even a mug like me can do this. As he said if I have problems just contact him. Can't complain about his service.
I reckon I'll try black and red/copper and they should cover most of my requirements. I'm working mainly at the other end of the scale than you, as I'm mucking about with rifle hollow points at the moment. Got plenty of pistol cals but all in rifles. Finding now that I'm doing more cast shooting than anything else. Here in TAS we have supply problems at times but with a shed full of different alloys (about 2 ton) and some casting gear I've got it all covered.
