Manifold Fabrication
 

I have been told to use 1 1/2 inch weld els for my manifold over and over but i cant believe it. That seems like too small a diameter to fit the ports of even my d series and i need to make a b series manifold.

so, what size are you guys using? maybe show me some pics if you could. especially the ports(looking into them if possible once again)

Thank you in advance you will be saving me money on returned orders of wrong parts from mcmaster!

Beau made both of these, both B-series, and T3 flanges, all used with stainless weld el's from mcmaster.com

there is some stuff in the faq also

Re:Manifold Fabrication
 

beau should be selling those.........i would take one for a d series and a 14b!!!!!!!

Re:Manifold Fabrication
 

I can make a standard sheet metal collector but how do you make those as kickin tube collectors on Beau's mani's?

Re:Manifold Fabrication
 

I was also wondering... i am going to use MIG because i have no access to a TIG machine at the time. what wire do you MIG guys use for the manifolds? do you use a 305 for the stainless to mild steel welds?

Re:Manifold Fabrication
 

the welding el's are about 1.9 inches OD...actually the 1.5 OD tubes are slightly larger than the exhaust ports. You might want to grind the ports on the flange to get a smoother transition.

but go ahead and use the 1 1/2 ID elbows. (schedule 40) THEY WILL WORK.

thanks,

i thank you sir. I am taking welding classes at my local vocational school and the instructor said that i will have to use a 305 MIG wire to wled the stainless to the mild steel. what do you guys use for MIG manifolds? i want stainless but i still need to work out all the details before i send my money to mcmaster.

thanks a ton -tom

bump ;D

Bump this ---- up, I have a MIG welder and I want to try to make my own manifold...where the ---- do you buy the exhaust flanges for the head? I vote for Beau to make a FAQ on making manifolds.
