And then there were two.
I'm terrible at taking pictures. Maybe it's my small workspace, or how cluttered and close all the stuff is... It's hard to get a clean shot of the new bits.
Anyways, check out the fitment! I'm pumped! I feel validated in the N+1 tool purchase.
3 down, one left. Anybody have ideas for how I can hold everything in place during finish welding?
In reply to Brotus7 :
Tack weld square tubing to the outside of the pipes creating little "boxes" every 12" or so. They'll do a lot to keep everything in place as you weld up the input flanges and such. Also, if you have a spare head or welding table, bolt the header down tight while welding to prevent warpage.

Peter, that's a good idea and I have plenty of scrap lying around.
4th tube is in and was surprisingly tedious compared to the others. Now to zap away, my favorite part. Since this is only 18ga, I'm using mig wire instead of the 1/16" filler I typically use for 16ga tube and it's working pretty well.
Project isn't dead, yet. I'll call this chapter "E36 M3 or get off the pot!"...
I finish welded and sandblasted the header after my last post. Then life got busy, and I was generally choosing to go mountain biking instead of working on the car when I had time, probably because I didn't want to make a decision.
In any event, I'm focusing on getting the engine running and then see if the flame comes back. And if not, it's been fun and will be worth more if it runs.
With the header done, I wrapped up fabrication the cooling system (man, what little aluminum welding skill I had evaporated!). Hopefully the fittings are water tight.
I designed and printed a fuel pressure regulator mount this week and now have the fuel system half plumbed.
After fuel, I think it's time to start wiring.
You've come too far to give up now! You've got this.
Some pics of the Birkin pedal setup (context is in another thread). Let me know where to zoom in. I should note that I think my car was modified before my ownership to allow for more driver inseam by moving the pedals away from the driver. The white sheet of plastic is not typical, I think.
Entirely too much work went into this clutch cable fitting to convert from hydro to cable clutch.
3d printed a few prototypes. The pedal cluster initially just had a hardened steel bushing riding in the aluminum pedal... That just won't do, so I pressed in a bronze bushing and bored it to size.
The actual fittings were a fun exercise to figure out how to machine and I'm pretty happy with how it feels.
Other updates:
Um, next on the docket is to stick the pedals back in, connect the clutch cable, and machine up some tube nuts for the shift linkage heim joints.
Progress feels good!

Thanks for the pics. Looks like Birkin changed their pedal setup some time after your car was build. I like how clean your pedal box is.
