Re: Making ZA27

I did some research on the matter and found out some interesting facts, when alloys of metals with greatly varying temperatures are made, as Frank said they start with the highest temperature metal and work their way down. The addition of the lower melting temp metals must be done quickly and done u...

Re: Making ZA27

Ok, so we should start with the lowest melting temperature metal and 'dissolve' the higher temperature metals in it. I didn't think it worked that way. Thanks guys, I'll keep you posted on how this experiment turns out.

Making ZA27

My casting buddy came by some zinc ingots and suggested that we mix up a batch of ZA27 and see how it pours and how the parts made from it perform. I thought it was a great idea, but then we started thinking about how to melt and mix copper, aluminum and zinc when their melting temperatures vary so ...

Re: NJ/NYC/LI Machinery Movers

John,
Give Hopatcong Rigging a call, they're located in Sparta NJ. I used them many years ago and they did a good job, since then the business changed hands, so I don't know how the new owner is to deal with. Without exception, the move always cost me more than the machine:)

Re: 1” scale rivets

If you are not actually fastening parts together, an alternative is to punch/press artificial rivets. I disguised my whistle to look like an air tank by pressing artificial rivet heads around the circumference on both ends. An appropriate jig for straight rivet runs can be made easily, a jig to even...

Re: shipping engines

Fred, I purchased and had two 1" scale engines and tenders shipped within the last three years, one from FL and the other from NV. I used Freightquote.com and was satisfied with the service and price, they were both shipped uninsured (that was my choice). What is absolutely essential is to crate pro...

Re: Do wheels have to be cast iron?

I cast a few car wheels from brass and shrunk on a steel tire and they seem to work fine, never tried it with a driver.

P.s. RONALD you make some really fine castings!

Re: Nelson's tube expander

Jim B. has a boiler that was made using this technique, and I've learned that someone at NJLS also built a boiler using this method, I'm going to chase that lead and see what I can learn. Fender is right about not over expanding the tubes, Nelson warns about over doing it in his book; I was able to ...

Re: Nelson's tube expander

I'm neither a good enough welder or silver solderer to attempt boiler construction, but I was intrigued by this gadget and would have bet my next paycheck that it wouldn't work...as I said, I was surprised when it did! Thank you all for your replies.
