Custom manifolds

Built a intake manifold for my 29 Sixty this summer. Nothing to it.
Not having any luck loading pictures tonight sorry. Just use whatÂ’s left of your old one and jig it up. It was actually pretty fun.

I would really like to see some pictures if you can get them to load. Mine is a '32 Fifeteen. Thanks for your help.

Wig, I bumped the thread “They’re still out there” to the top. Look on page 15 for manifold pictures.

Hope that helps

Very nice work! Do you remember what type of material you used? That pipe or tubing looks thicker than exhaust material. It looks also that you used pre bent material. Where did you find it? Thanks for your help.

Thanks.

That was just schedule 40 2”black pipe. The bends are pre bent and are meant for welding. I think they were called weld 90’s or something like that. It’s my understanding they make 45s and tees also, probably crosses too. I got them at our local plumbing supply store. They did have to order them since they didn’t have six in stock. I don’t think the 15 would use as many 90s though.

Good luck with your project.

Hi Bruce P.
I worked on gas pipelines for a couple of years back in the 1970s and we used a lot of those in the 8" and 22" lines that we were laying. Back then, we called them 'forged bends'. They came in 90s and 45s. Anything else, the surveyors would mark out the angle needed and the welders would cut and face it and then weld it in.

Don't think Wig will need anything like that big for his job.

I have also made a couple of manifolds for smaller engines using ordinary black pipe and 'lobster-backing' the bends. Both times, the engine was miles away from the welding so shop I cut a piece of 1/2" mild steel plate for a base plate, cut, shaped and bored the mounting flanges and tacked them to the base plate, built the manifold onto the mounting flanges, let it all cool right out and then cut the flanges off the base plate. Had to ream one bolt hole about 1/16 of an inch to get one to fit. The other slid straight on.

Just my 0.02.

Thanks Deas. That pre bent 90 in 22” would be an impressive piece of gear!!

That may be overkill for Wigs manifold, but it would have some impressive flow numbers!!!!

Wig,

One source for butt-welded fittings is https://www.mcmaster.com/pipe-fittings.

I used a square tube to build a manifold for my FIFTEEN then fabricated a bend for the exhaust pipe. My pipe is larger than the original and my setup does not include the heat box as the square tube resides where the heat box would be. When the engine side panels are down they hide my shortcut manifold.
