Welding and machining aluminum wheels.
OK as you may have guessed by my nickname I'm into Porsches except my income doesn't match my taste in cars Anyway I need to buy a set of track wheels for my car so that I can run DOT rubber at the track and not where it out on the street. The trouble is I'm tired of paying the "Porsche Tax" on everything Porsche related, kinda reminds me of when I built and raced Fords before the 5.0 craze dropped prices inline with Chevies. Anyway Porsche uses a 5x130mm bolt circle and an odd cup shaped taper for the lugs to seat into, I'd like to buy some cheaper wheels in a Chevy or Ford bolt pattern and weld up the holes then remachine. The question I have is will I significantly weaken the wheel? My brother has an industrial sized welder so I could get good penetration that I likely wouldn't get with my Lincoln SP 175 tig machine. The side benefit here is that I'm partial to American Racing Torq Thrust D's which are a modern version of the old Torq Thrusts from the 60's and 70's and where available in Porsche sizes back then. I'd like to run 17x8 and 17x9 to fit my big Brembo brakes and 13" rotors and just about every decent wheel with a Porsche bolt pattern is super expensive, the AM wheels are cheap by comparison. The machining part should be no problem, it's the welding that concerns me. Also I'd be stripping and powder coating the wheels to factory finish isn't an issue. I've got an Eastwood powder coat gun and an oven large enough for two wheels at a time.
