Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Hi Gil,
I have Nick to pray my questions to Red Rider to transfer. No reaction! I am deeply disappointed. This are my questions.

I´m a model maker (72 years old) from Stirling, Vakuum- and Hit & Miss scale model gas engines. I live in Leipzig / Germany. My kanal of you tube is "charly05ize". I hope in this Forum help for my problem to find. I´d like from Doug Kelley "Callahan inspired Cam Stopper freelance build gas engine" to copy. My Problem, no plans and from Doug Kelley no Adress. I´d like the plans to buy, not as gift. Can me somebody please to convey the plans. My E- mail is: Charly-04@gmx.net  I´m possible also interested for a Plan from Callahan Cam Stopper. Or also some drawings or detailed photos from the cam stopper mechanism. Mine experiment by "Cooper Tools" plans for a Callahan Cam Stopper to obtain is failed (out of business).  Sorry my english ist very bad, I understand only simple words / phrase.
Regards from Germany  Karl
