I live in a part of the country (USA) where no custom fabrication for the marine industry is done and have been unable to find anyone who can make radar arches or grab rails, so have been considering whether to buy a bender....but don't do enough work to justify the cost I don't believe. In my research I found this summary of bending methods with different types of benders, and the results they produce: http://www.oceanmachinery.com/how-to...e-and-tube.htm

Depends how much you want to spend.

Quite a few on Ebay.

These looks promising for sensible money - may even import one myself.

That looks OK, I might see if I can borrow a conduit bender, I've a piece of 1" tube I can test bend.

You haven't got one have you Stu?

Tig welders/inverters

Might well take you up on your offer Stu.

So this brings me onto TIG welders.

What's the minimum Amperage I could get away with for welding 1" diameter tubing to a good standard? I've used a 140 amp one before but can't remember what amperage I used, I seem to think it was about 100ish amps.
The other thing is that the higher amperage ones need a 16A supply at 240v's.

I know they SAY that you need a higher amp supply but I have used a 205amp Mig - a 165 amp tig and a 30 amp plasma cutter on a normal 13amp supply - along with a 3hp 14cfm air compressor. No problems at all - mind you I have proper fuses and not trip switches - I suspect they are more tolerant.

Usually around the 45-55amp range. I rarely go past 60amps even on quite thick sections. Are you thinking about a real TIG welder or an inverter?
