I have built a Coles Corliss, finished about two years ago and sorry to say, I didn't keep build notes although I have a U-tube of the engine running (link below), some of the machining setups in a .pdf file and a few up front comments.
First comment: the drawings mostly call for #8 screws throughout. There are a few places where #8 screws are well suited but in many places either #5 or #6 screws are better suited. I used mostly 5-40 screws in many places. Second comment: Tolerances are not called out but I find it better to avoid close or tight fitting on most moving parts, avoiding too much friction.
OOPS, the .pdf machining file is 12Mb, unable to attach here, not sure how to post it! Ideas??
