The next job is the eccentrics and the bronze eccentric castings are drilled in one piece with the 6BA drill  and then sawn apart and one of the top holes is drilled the clearance size and then the two halves are joined together using the tapping drill to hold the two halves correctly in position and then tapped. this ensures that the two halves will stay correctly positioned when bored out to the 5/8ths dimension.

FYI, I  pinged the manufacturer who said theSparex Nbr 1 has been discontinued.  They still make Sparex Nbr 2 for brass and copper though.
Yeah, that matches what we see in the real world. Nice to have it confirmed.  I won't spend any more time looking for Sparex No 1 now!  :Lol:

Thanks for doing the research, Chris.

Nice tubing. And I  recognize that  little vise, got one just like it from my old Unimat setup, handy for bench work.

my order of telescoping copper tube arrived, started work on the keel condenser.. some copper flex tube, little cero-bend and some gentle persuasion resulted in the a U-bend that looks good,, will have to make a jig to hold things in place while soldering. at least plumbing solder should be fine for this..

Your Own Design / Re: Building a twin cylinder inline i.c. engine

Elvis has not left the building!!! I am currently troubleshooting the engine and waiting for the first run. The intake manifold that fed two cylinders and used a single carburetor did not want to seal against air leaks, so finally I made up two individual intake manifolds and used two Traxxas carburetors.  (These Traxxas Pro-15 carburetors work fine on my single cylinder engines with the same 1" bore.) I have things to a point where one cylinder is firing consistently but the other cylinder is not firing. I have went to a larger diameter flywheel and that helps, but doesn't quite do the trick. Today I used my new compression tester to check compression on the cylinder which is firing, and the compression tester is registering zero compression.  I will post more as the troubleshooting progresses.---Brian
