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.

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.

Nelson's tube expander

I was curious to see if the copper fire tube expander that Nelson describes in his book would work. So I made one from an Allen head cap screw and some soft nylon rod that I had laying around, then reamed a 5/8" hole in a piece of steel, annealed a piece of of 1/2" L copper water pipe and expanded t...

Re: Gibs & Material

Tom, attached is a photo of salvaged gibs that I have no real use for, if you want any, just pay for shipping.

Re: Working with small wood pieces/patternmaking

Like Harold, I use my metal working machines for some operations, but mostly I sneak up on the dimensions by sanding on a disk or spindle sander...glue on pop sickle sticks, tooth picks, any pre-made thing to get the shape that I want, then smooth it all out with some wood filler, hand sand it smoot...

Re: Suspension problems

Performance update with the spring loaded heart rockers is that I didn't see much more improved performance, pulled 7 cars and still experienced some slip on start up and on grades. Much better than it was before I started making the adjustments, but It will never pull like a Pacific.
