Default Gauging interest in a 304SS or a 316SS Head Flange

Getting one of these made for my project in either 304SS or 316SS. Have a couple other people interested and wanted to gauge interest and see if I should get more than a few cut.

It will be built for Schedule 40 1-1/2" pipe, with a port match to the head ports.

No idea on price yet.




Post here with how many you would want, and how much you would pay for one. I will be getting quotes this week.

Also will get getting T2 flanges out of the same material.

I was just wondering about where to source a stainless version of this as I model my manifold plans. PRL sells a steel version but only stainless weld els.. Not sure unlike metals is going to cause any problems other than corrosion. I can get steel weld els elsewhere, but they are actually more $ (from McMaster) than the SS ones.

How thick will these be?

I am going to try to get a quote from PRL for them to machine some flanges. But as a reference PRL uses the flanges they sell with the SS weld el's with no problems on the manifolds they build. I have talked to them about them before.

Here is the flange drawing. It has not been tested, so don't assume its complete.

I say 5/8" if possible. Go big or go home. That way the first milling after it's welded brings the flange thickness down to 1/2". Maybe straighten the taper a little at the end so the ports don't get smaller as you mill the head flange down to nothing. Not that I'm worried about warping or anything...

Also, I'm down for one if Aidan build's me a manifold with it. Aidan, I'll assemble your short block?

I'm going to be building the manifold on the spare head. Hopefully should help keep it from warping. Unless I can get this giant piece of steel I've been eyeing in a corner of the machine shop at work.

I think 5/8 is overkill. 3/8 used to be acceptable. Thats how thick my flange is.

A little exhaust leak is fine. Nothin like a bit of carbon monoxide to make you tired before track days.

Dimensions correct of the head side? I've got another copy of a .DXF, that is a complete cluster **** of someone trying to painfully draw something in AutoCAD, hoping to use your file to make sure mine is right, do have differences, pretty sure yours is the right one.

Maybe? I printed it out and it matched up to a gasket I have.

Is there anyway we can get a dxf file of it Aidan? I don't have solid works or really anyway of easily converting it to dxf. I was going to cut one out on a CNC plasma cutter to play with but it won't take a solid works file directly
