Ok just pulled the board out.
Heres some #'s I grabbed

Thats not the graphics board part number Dave, that's the peripheral control board. It contains the tape reader interface and some other functions. You need the graphics controller. Maybe I've been looking for the wrong schematic all along. In any case I just sent you every autocon/dynapath system 10 and delta 10 schematic I have. You should have them this week.



Dammit, which one is the graphics board than? I traced wiring from the monitor back to the dynapath and it came into that board, on the front of the dynapath its plug is j11-crt. Man now I am confused what the heck am I supposed to be looking for :lol:  This is definitely not my department :cry:

Thanks for sending the Schematics Bruce, you've been a huge help, I really appreciate that.

I'm admittedly not a dynapath expert, I just bought the dealer out, so don't trust me! I just assumed the graphics board controlled the monitor, perhaps not if the cable does indeed go to the peripheral control board. I've never actually seen a system 10 control in one piece before, and unfortunately, I don't have any schematics left to consult :D , but you will soon! Make sure the schematic matches the board in question, I sent you 7kg's of the stuff so it's kind of multiple choice... Best of luck with the fix...

Sounds like a lot of schematics Bruce! I'll let you know how it all goes when the schematics show up. Thanks again.

Absolutely. In fact I think C2 and techtonics both offer a CNC mandrel bent 3" over axle piece.

Yes mk1 will be different from the mk2/3 (which will be the same), but the other main criteria I am trying to meet is for them to be 1.6 and 1.9 (taller block) compatible, we have a lot of customers that upgrade from the 1.6 to 1.9, I'd like for them to keep the same pipe.

Yes, its SS, and a sanitary grade at that, it won't corrode, the turbine outlet flange is 1018crs, but at a half inch thick if you ever managed to corrode that your block, manifold, turbine housing etc would have rotted out much earlier.

THe problem with steel is that a 3" U bend the tightest radius I can get is 6", which is too big for our engine bays. With the stainless I can get them in a 3.5" radius.

As soon as we can get our mill back up and going we will sell the flanges.

Dave,
         
Will you be able to utilize any of this new technology/ source in the manufacture of your exhaust manifold?  Will this help with any sort of  savings in manufacture time?
Thanks, Jim

I'm curious to know what ( back purge the weld ) means ? I've never heard about that? what does that consist of ?

It is when you run sheilding gas on the back side of the weld, it is "purging" it of atmosphere. So if you take the downpipe for example you would cap off both ends after tacking it together, and then would insert a tube that was Y'd off your sheilding gas tank, and run shielding gas into the down pipe, as you get close to the end of the welding as things get sealed up you open up part of the cap, or make a hole in the cap (depending what you are using for caps) so that you can finish the weld without the gas trying to escape (under pressure) through your weld.

Most metals do not require back purging, but SS is a bit of an odd duck all around. When you don't backpurge you risk getting charcoaling (sp?) on the backside of the weld, leaving room for perosity and other weld imperfections. It also helps keep the HAZ (heat affected zone) smaller by being able to move faster without the worry of contamination.

Anyway this is a long post, esspetially becuase im not a welder, I just play one on TV.  :P
