    Rotary valve leakage

    Well all progress has stopped as it appears after 35 years in this house we are moving! Lots of work to do in the new place including an awesome shop. More to follow but that has become my new full time job. Whew! Moving the shop and machinery will be a huge challenge.

    Rotary valve leakage

    Ha! At my age I worry about lost minutes! Always feel bad about scrapping a part but it's more fun than Sudoku.

    Rotary valve leakage

    nx06563, Thanks for the reply. My goal is to experience myself into an IC engine and I see you are already there. Congratulations. I also appreciate different and non conventional designs and yours definitely qualifies. Do both pistons meet at TDC? I suppose the easy way out of my dilema would...

    Rotary valve leakage

    Charles, I had a hard time understanding the valve as well so the first was made out of a 3/8 wood dowel rod. It actually worked probably due to the reduced clearances. Found this engine design on line about 3 years ago and since learned it came from a 1960 vintage Popular Mechanics mag. Using...

    Rotary valve leakage

    Just finishing up my second engine build. My first was a small wobbler and I wanted a challenge so dove into a two cylinder. Hope to make it to IC some day. Problem: The rotary valve is one of the reasons I chose this engine build as I did not feel confident in machining gears or cams. BUT that...

    Graphite

    Hmmmm, I don't know much about EDM machining but I wonder if the graphite rods would be of a much smaller diameter. On the dust issue, sounds like it would be prudent to wear a respirator while making dust on the lathe. Have not decided on a Stirling design to build so accepting suggestions...

    Graphite

    I was thinking about using the shop vac as a dust collector but not sure I wanna give up the free way lube. Ha ha. Maybe a topic for another thread but talk to me about cutting tool geometry for graphite.

    Shop lights

    Changed my shop lights to LED last winter when I got tired of dim flickering lights in a cold shop. Went with the direct wire variety that does away with the noisy ballast. Love the instant and silent bright light, cheaper to run, too. I see it's been a few months since your post but got mine...

    Graphite

    Thanks Chiptosser for the explanation. I can see the advantage of graphite in a Stirling now. Terry

    Graphite

    I have noticed several Stirling engine plans call for a graphite piston. Can anyone explain why?

    Stirling Engine from Norm Jones drawings

    Bob, I will contact Model Engine Builder to see if back issues are available. Thanks for the tip and prompt reply.

    Stirling Engine from Norm Jones drawings

    Hello Bob, I congratulate your grand daughter on her Sterling, outstanding and a beautiful job. I have always wanted to do a Sterling and that engine looks like a great place to start. Is there a way I can get the drawings? Thanks! Terry from Texas.

    Every Boy His Own Manufacturer

    Wow, That book is a treasure. I had no idea the interweb had old publications, Popular Mechanics etc for all to see. I spent hours with these as a kid. Also had zero interest in sports, preferring to cruise the alleys on garbage days for treasures (much to my mother's chagrin). I still do that...

    Design and build side-shaft hit and miss engine from bar stock

    Wow Brian, Hit and Miss engines have always fascinated me having collected and restored a few. The sideshaft engines are especially attractive because of all the moving and wiggling parts. I am finishing up my second model engine now, working toward I.C. someday. Will be watching with interest...

    Import rotary tables

    I found a six inch Yuasa for a bargain price a couple of years ago. Then found out why it was so inexpensive, it was full of water! Lots of heat and crude language but finally got it apart and working. It is horizontal/vertical, four slots, #2 Morse in the center. It does have some backlash. All...
