I built this as my very first aluminum TIG welding project, welds are definitely not up to Ben's standards, but I'm starting to get the hang of it. Bit more practice an I should have decent welds. Also the aluminum was a scrap sheet that been sitting outside for years, so that likely didn't help matters.
But overall seeing as it's my first effort I'm pretty happy with it.
Would do a couple things different for a short run production, use the next size up petcock valve, weld the baffles in a bit different, etc.
I made it to clear the factory trunk springs, but not intrude into the engine bay much. It has a petcock and a tube, so to drain you stick an oil pan under the /6 cooler and open the valve. It's fully baffled and holds over a quart of puke. The barb's are 1" but I could also check out what's involved with using AN fittings.
I would likely have them power coated semi-gloss black.
I have the patterns for it so it would be easy to make more.
I have to check the price of materials, parts, powder coating, etc, but I'm thinking $150-$175, or $200 + ship and I supply the black braid hose and clamps.
So is there any interest?
