....in 304ss 1/2 Inch thick and for the SOHC VG30.
I can send Manifold to head gaskets your way if needed
I need 5 pairs right now and possibly more in the near future
I tried BMC Race and got nothing but the run around for a few months.

Post here or E-mail me at SteveZ31t@Yahoo.com if you can help me out. Thanks

 

Why CNC?
Why not Laser cut, or Waterjet?

 

PM'd.

 

Do you have any pictures of old ones or anything.

as for why not to laser cut. Assuming that his part is a half inch thick that may end up changing the tensile strength and the life of the metal. I am not 100% sure but it would just seem that looking at the numbers on Matweb that it possibly would change it's rigidity.

 

dont know if it is different from DOHC VG bu we have DOHC VG in stock

You are not sure at all. It is going to be welded, and laser doesn't add much heat at all. I just suggested these because they are considerably faster and consequently cheaper on multiples.

uh last I checked welds improve strength cause you are adding metal to the part..... heating a part however can cause it to lose strength. Not trying to be a ***** just making sure you know that. As for the laser....here you go this is why not to...

"Q: How do abrasive jets compare with lasers?
Abrasive jets can machine many materials that lasers cannot. (reflective materials in particular)
Abrasive jets are great with Aluminum, Copper, stainless steel and other reflex metals. These are not easy to cut with a laser, and can damage the laser.
Abrasive jets do not heat your part. Thus there is no thermal distortion or hardening of the material.
Precision abrasive jet machines can obtain about the same or higher tolerances than lasers (especially as thickness increases).
Your capital equipment costs for water jet are generally much lower than that for a laser.
Abrasive jets can machine thicker materials. How thick you can cut is a function of how long you are willing to wait. 2" in steel and 3" in aluminum is quite common. I heard of people doing up to 10" (254mm) steel, and 24" (600mm) thick glass with high horsepower systems. Once you get over 2" (50mm) thick it is very difficult to get precision, however. Lasers seem to have a maximum of .5" - .75" (13mm-20mm).
Abrasive jets are safer. No burnt fingers, no noxious fumes, and no fires. (You still have to keep those fingers out of the beam.)
Abrasive jets are more environmentally friendly. (I hope this is a selling feature to you.)
Maintenance on the abrasive jet nozzle is simpler than that of a laser.
Abrasive jets are capable of similar tolerances on thin parts, and better on parts thicker than .5"
Abrasive jets do not loose much "focus" when cutting over uneven surfaces.
While lasers are often faster on thinner materials, it may be cheaper and faster to simply buy two or three abrasive jet machining centers to do the same work. Also, you can stack materials.
Modern Abrasive jets are typically much easier to operate and maintain than lasers, which means that every employee in your shop can be quickly trained to run it.
You can't stay long at the same point with laser or fusion of material will occur.
Laser cut is under inches (near 4 inches for WJ), but can do a better job in controlling depth of cut (ex.: cutting slot in tubing is possible with a laser, but difficult with abrasivejet).
Laser has higher power consumption (power factor about 2%) (ex.: for 1 kw output you need 50 kw input for YAG) (CO2 more efficient, but less precise ray).
Laser needs a good "chillier" for cooling. "

They are different

Thanks for all the PMs/E-mails I got someone working on them now.

nobody wants to use ghetto looking scaled plasma/laser cut flanges man, billet flanges produce so much of a nicer finished product..... + plasma/laser cut flanges are never flat

I'm 51% sure that full-race manifolds use laser cut flanges.. and you know how people love to ride their nuts. BUT no one ever complains and their products are quite <FONT COLOR="blue"><u>Functional (Over Forum)</u></FONT> from my understanding.

 

once again you guys have never heard of matweb have you?

 

Whatever you think you learned from clicking 50 different a36 properties tabs on matweb you can toss out the window by the time have a finished part. It takes a lot of heat to get good penetration when welding onto a half inch flange and any heat treatment you see on matweb will be out the window.

If anything, I would have the whole manifold stress relieved after welding, and then face mill the flanges flat. I don't see a need for any heat treatments to increase the strength in fact I would be more concerned about keeping the ductility up.
