Machined all five of the bronze bearings for both engines. Turned out very nice and I am really glad I kept hunk of bearing bronze from 15 years ago! Expensive stuff.

Cut the engine mounting ring for the engine stand for both engines. Will be firing up the TIG rig soon.

Looking good I have almost finished my 9 cylinder which has taken 5 years on and off and hopefully I will soon be running it up. I am currently also in the process of completing a hit and miss Rina engine which had been put on the back shelf whilst working on the Hodgson but is coming on nicely.

Built the alignment fixtures for both engines crankshafts. Used a caswell cold bath black oxide process on the cylinders. It turned out to be pretty good and it was simple. You can see the untreated cylinder on the right.

Been working on the cylinder head CAM programs. What you see here is the result of four operations totaling over seven hours of machine time per cylinder head. The machine work is only 75% complete as each head will need at least 3 more operations to finish. I expect another 3 hours of machining will be needed to complete the head. I need 27 good ones for both engines. Aluminum is getting expensive..... lots of trial and error.... 😃. I understand now why people have told me that the cylinder heads are the hardest part of the build.

With a 5-axis mill and tool changer, you'd knock those babies out quick. :D

Lacking that it's a slog. That groover is a tight fit.
