homemade Flange material

well, I need a few honda D-series head flanges, and am having trouble sourcing them =/

I have contacted Cheapturbo.com, and they require a minimum order of 10, which I don't need that many (yet)

So I figure a DIY-flange approach would be the way to go.

Either way, I'm pretty new to this stuff, I just bought a MIG welder, to help me with my project(s) So the sky is the limit with what I can do.

What material would be best to work with at home... 1/4" mild steel, or is that too thin? do I need 1/2"?

is that something I could cut easily with either a Jigsaw, or a Sawzall and some Hole-Saws?

Thanks for any help

I'll take a few, if the costs is resonable.

I would also go with 1/2 thick.

Re:homemade Flange material

1/4" is a tad thin for a good flange.. look at cheapo headers compared to a good quality one's. The high end stuff allways uses at least 3/8 for flange material.. This is not so bad to drill with a bi metal holesaw. so long as you have a press and use alot of oil... machine work is a key as the ports are most likely not round and a transition needs to be hand machined with a die grinder.
