Why everything that is supposed to be gray has changed color to tan may be due to it being 48 year old Polaroid?
Yup.

Re: 1” scale rivets

I think if you use drive screws, they'll work fine in the PVC. I've got a few little ones I could send you for a test if you PM me your address.

Re: Cylinder Borning

Here's how I did mine. In the first photo the cylinder block is attached to a t-slot cross slide. As Rudd points out above, you can do this without the t-slot cross slide. The fat boring bar is between centers to minimize any flex of the bar. You can see the toolbit sticking out of the bar. In the s...

Re: 1” scale rivets

I'd take a look at the drive screws from McMaster. They have some rather small ones. If you must have pointed heads, you'll probably have to make them yourself. There was an article in Live Steam years ago about making a rivet making machine. I'm away from home and will have to wait until tomorrow n...

Re: Possibility for a 2.5" scale dynamo

I agree with Fred. I have a turbine blade from a model jet engine and when I hit it with my shop air It easily spins up to 10,000 rpm. In fact it is scary to hold the shaft I spin it on. John B. OTOH, it would seem that you could make a turbine that is "inefficient" and would not spin that fast.

Re: Possibility for a 2.5" scale dynamo

I've been working on some dynamo castings for 1-1/2 scale and have decided not to make it function. The folks I've talked to say that a working gen. makes lots of annoying noise and the exhaust will come right back in your face. One friend made a working gen but doesn't use it for these reasons. I'l...

Re: Gene Allen's model engines

Thanks for that. I had the pleasure of visiting Gene at his home shop and also of running his American. He was a true gentleman. Humanity needs more like him.

Re: Rebuild of an Allen Mogul.

... My question is, which material should I use for the liner? in the vintage motorcycle world( another obsession) we use cast iron. I've seen many references to using 660 Bronze. What are your thoughts? Cheers Ant Well, I say don't reinvent the proverbial wheel. The original design is for cast iro...
