I will NEVER make another ring! Had no source... That is if the model isn't a 'close to scale' and the rings needed aren't some odd ball size but that was usually the case building IC engines.

THANKS!

Diminutive sized rings are not so awfully hard to make.... even gapless ... along with the necessary heat treating. There are many written texts about this in the IC engine world.

This post is 14 years old WOW The ball valve is the worst valve to use for a throttle. Sorry that's how I feel about it. Interesting read though... So Dave, what valve (that is still available) do you recommend? I recall that you used a swing gate at one time and on searching, the smallest found wa...

Interesting.... Aluminum parts on a locomotive or anything for that matter will always give itself away by shedding the paint. (couldn't help but notice) If I may offer a solution: I used to work on aircraft (aluminum money holes in the sky) and when repairs were made or airframe parts were construc...

Hopefully the porosity induced by the laser sintering process does not interfere with the injector performance. Some amount of roughness on the body inner surfaces shouldn't have any effect since the cones are the working surfaces, that is unless they are 3D printed too... But then again, there is ...

Russ is alive and well, had a visit with him while on the east coast last week. He is more into his steam launch than he is into trains these days, but he did pop by WW&F railroad in Maine while I was there for a winter photo freight. His work is magnificent all around. That's grand great news ...

I need to quit my job or just retire and go home and work on my Chu-chu train. I highly recommend it! I retired when I was 54. To this day, I don't understand how I found time to have a job. Idle time, for me, is a myth. Harold Harold, My dad says the exact same thing.... he is encouraging this ret...

Very good! Thanks - That will be some good reading.

Marty,
Good point. The ports are cored in and exit out pretty far at each end - why I can't just cut the cylinder block down narrower. The longer registers will need to be relieved at those ports.

Thanks for the replys and recommendations. The cylinder cover idea is probably how this will be solved. The OA block length is 4 1/2" and could be shortened a bit and the absolute maximum stroke is 3 1/4" - but would rather keep it at 3". The problem may not be as drastic as I was thi...
