Weekend before last, I did a smidge of checking on the accessory bracket. I need to take more measurements to complete the design.
My alternator mount hole is a little bit off.
A 0.005 feeler gauge stops here and doesn't go in from the other side, so that tells me about which direction I need to move the arc in the part.
I modified the oil filter adapter again, of course realizing the need for this mod AFTER I had it anodized.
I hooked up shop air to blow out the hole continuously during the milling & tapping operations to keep the inside of the part clean.
I had to set up some Rube Godlberg fixturing, including blocking off the block port in order to make sure all the compressed air went out the port I was machining instead of rushing by it, creating a venturi pump that pulled chips INTO the part.
Result:
The elbow is a 3/8 NPT male to 1/4 NPT female street el, which is the most compact arrangement possible. This particular part I had previously modified by running the pipe die a little further down it. This actually made it a little small for the size the oil filter adapter port ended up. I ordered another elbow, so theoretically the fresh elbow will work fine, as I appear to have plenty of clearance for the socket to install the Aurora oil pressure sender/switch.
Last weekend I did some leak-finding on my roof, and didn't get a lot done on the car.
I decided that I'm better off completing the first water manifold that I thought I ruined vs. making a multi-piece throttle adapter... So I did the first ops on that.
I still need to drill the hole in the upper radiator connection neck for the Mishimoto weld-on fill port... and order another fill port. The new thing I need to do is mill a pocket around the slot, then fit a lid for that slot, then have the lid welded into place. I also left one of the EGR valve mounting bolt holes, as it doubles as a support for the fuel rail where the fuel lines connect to the rail... probably useful to keep.
