Thanks Howard. Those are definitely a good option and save's some space. I like having a spare tank so I can continue working when I replace the empty. I also had another cheap regulator that came with the welder and a spare hose.. So I just bought some cheap silicone plugs to make my own purges. 1/4 of the price for three times as many vs the welding brands. I just use sintered air fittings as the diffuser. Quick disconnects are nice too.Get one of these and you can use one tank.
And don't forget to add a drain bung and plug at the low point in the system.
Thanks, I hadn't considered that. I'll do that when I go back to recess the bolt holes. I think one or two heads may interfere with the belt just slightly. I also need to add a shallow channel on one bracket for the head gasket that protrudes from the side of the head. It prevents it from sitting completely flush, so I have not fully tightened it downNice job sneaking that tensioner in there.
Looks like you used a chambfer bit with bearing guide in a router. I've done the same and it works great. But the radius around the alternator fan might benefit from a much deeper chambfer to not impede airflow from the fan.
