Thanks for all the replies, nice to see that folks really want to help out. This thing has become a bit of a carnival act for me.
Years ago my wife gave me a casting and plans set for a Bob Shores Little Herc engine. At that time it was still a mom and pop operation; pop had passed away but mom still ran the website. Then she passed it on to someone else who, apparently won’t ship beyond US borders. Anyway, this engine is a little scary for me since it’s really at the extreme for my Sherline equipment so I thought I’d try his Little Angel which is built with bar stock and can easily be machined on the Sherline equipment.
The internet being what it is, has a number of bogus sites selling these plans and I fell victim to one of those.
I'm not really that anxious yet since I have a couple of steam/air projects I can work on this winter. And since most of my challenges come from the size of the Sherline equipment, I’m still pondering the purchase of a larger mill and lathe to handle the easier, larger model IC engines mentioned above.
