    Beautiful countersinking Jim. Getting that right is often more difficult than meets the eye and surely it is a sign of good workmanship. After the pistons, glands and crossheads are done you will be able to determine how accurately everything lines up and slides. That's the important part. The...

    Bet your old shop steward has gone back to school - however this one looks pretty capable as well. I spent a little time over the last few days putting up webpage about a small marine gas engine model that I built - but all the while still thinking about our compounds! - John

    Jim, my plans both show the same dimensions as yours: the 1980 drawing for the non-reversing bracket shows 1/4" thickness while my 1970 diagram for the reversing bracket is 3/16". I made mine 0.213" thick for some reason. Even at that it is a little too thick as I could hardly get the...

    Hi Jim - Yes, Dorian did roar through here but nothing like down South - the ocean is cooler up here. You have done a lot of work on your engine in a relatively short time! You must be quite pleased to see the results - John

    So nice to see that those matching holes came out located symmetrically within the sole plate's corners. A perfect job of placing the ten most crucial holes in the engine. John

    Jim, you are moving ahead by leaps and bounds and it's looking good! Nice to see the columns already. I'm sure it will be a good feeling to see the cylinder block sitting in its proper position above the sole plate. "Meager" BA threads usually tend hold surprisingly well compared to Unified...

    It's already starting to look like an engine in those bottom views of the block. I guess it pays to have a good shop supervisor! Keep up the great work Jim. - John

    Hi Jim, the top covers look great. They will be even more fun once the flats are on them so both will fit in place at the same time. The question of flat or domed tops is probably personal choice and the domed type seems to be more common in models, including the compound pictured on Stuart's...

    Thanks Peter, I'll be a little slow during July and August as this is our (short) summer here so there is plenty going on outdoors these days. I am also trying to pick at a naphtha engine during spare moments but I am lazy so there should still be ample time to keep an eye out on the forum as...

    Hi all, I live in the Gulf of St. Lawrence (on dry land on an island). I enjoy following engine construction projects and HMEM seems a great place to do it. Better to watch from the inside than standing outside looking in so I joined up. Currently I have been following jpdenver's Stuart...
