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.

Re: water glasses

Bill, the sight glass turned out good and was straight forward to make. After grinding the lathe tools and making a trial piece to get the moves down and flush out the bugs I was able to make the two end pieces, including silver soldering, in an hour. Just waiting for the high temp o-rings and angle...

Re: water glasses

Bill, is there some type of port in the center pilot to allow steam and water to fill the glass? It seems like a snug fit between the end fittings' ID and center pilots' OD. Also, is the lateral hole in the end fitting 1/4" on the top end fitting and 5/16" on the bottom end fitting? I see the note b...

Re: water glasses

You anticipated my followup question, I wouldn't have figured that out if I live to be 100. Thanks Bill.

Re: Suspension problems

In an effort to get as much as I can get without taking the engine apart I did a variation on Mike's spring replacement for the solid heart rockers. I haven't run the engine with them in place yet, but they seem to redistribute more weight to the drivers. I included a photo of the solid rocker next ...
