Re: Steam turbine generator

Wolfgang, you touched on two issues that were problems for me when trying to build a functioning steam turbine and generator. I always had trouble finding the proper bearings for a 1" scale turbine generator (never did find them), and I could never find a source of iron for the field coil, I would w...

Re: Steam turbine generator

Looks like I'm going to have to come up with Plan C. I spoke to a few manufacturers by phone today and there's no way to generate the needed rpm to to develop voltage...so bicycle dynamos are out. Regarding LED color, I have a 6 volt battery system for lights on one of my engines, the headlight is i...

Re: Steam turbine generator

The lights on one of my Atlantics are battery powered and it works fine, but by the end of a long day's running the batteries are dead. I was thinking along the lines of Makingsmoke and using a generator with a voltage regulator and rechargeable batteries to keep the lights burning and recharge the ...

Re: Steam turbine generator

I'm resurrecting this old topic because I gave up on plan A and I'm onto plan B, and since there is nothing new under the sun here, I figured at least a few of you guys have thought about this or tried it. Have any of you tried to adapt a bicycle Dynamo to your engine or train to generate electricit...

Re: .268-40 tap and die ?

That may be an ASME #16, obsolete and out of production for a long time. I took a quick look through my oddball taps and don't have anything like it. Liveaboard may have the answer.

Re: Cement ties

Beings you're the expert in tie replacement, thank you Danny. Since it's an experiment, I'm going to try a few different track attachment alternatives. Keep an eye on my progress and let me know what you think of the various methods. John

Re: Cement ties

Thanks Danny, after reviewing the panel idea with Rick we rejected it and decided to go with individual ties. There are 24 in place out by the 1-1/2" car barn, check them out and let me know what you think. John

Re: The dumb ideas I get sometimes

I had similar issues with a permanent mold that I had made, it was very thin so I didn't think draft was that important...it was. You may also want to relocate your pouring sprue or at least make it longer to get more liquid head to help fill the mold and act as a source of feed metal during cooling...

That's a very nice piece of work! Smoke it up good before pouring, and please post a photo of the results.

Re: Cement ties

I finally installed the balance of my experimental concrete ties today. I guess I didn't clean out two mollies good enough and put hairline cracks in two ties, I left them in to see how the cracks will be affected by the freeze thaw over the winter. I was talking with one of the other members, who h...
