Re: New York Central Streamlined Hudson

Brian;

To add to what Jack said, get the black flux and the cadmium-alloy silver solder. The latter flows better and the black flux doesn't burn off yet is easier to clean off after you're done. Some folks worry about the cadmium in the silver solder but if you use common sense you'll be fine.

Re: Question: parts for a steamer

I would not fault TM if they decide to keep the policy in place. It's hard for folks who live in wetter climates to understand how quickly a fire can spread in dry brush. I've seen it first-hand and it's very scary to see how fast flames can move in 60 seconds. And TM could face a tremendous legal a...

Re: Question: parts for a steamer

... As Marty pointed out the cost of going to a show strictly as a vendor grossly outweighs the income from sales. So the fact remains on trips like that and even the few I make during the winter I have to turn them into vacations ... . Above is the core of the situation. Anyone expecting to make a...

The bullet train: Beijing to Zhengzhou

This is going to be long, and I realize that this goes against the unwritten custom of keeping forum posts to perhaps a single paragraph, but I'll take the risk because if it encourages one person to travel internationally and get outside his or her comfort zone it will have been worthwhile. There a...

Re: Sizing Truck Springs Questions:

Dunno about your main question, but I read somewhere about putting a round-headed screw in the bolster where it would seat against the sideframe in order to create a pivot point when the car is running light and the springs are pushing the bolster up against the sideframe. Thus it won't matter if th...

Re: Butt joint advice.

The issue I see is getting the edges bent to the same radii as the central area. Again, look for a press brake. I know that Monday morning quarterbacking doesn't help, but if you can't get this done, an oversize piece first bent and then cut and drilled might work out. Thus the edges that are diffic...

Re: Butt joint advice.

You realize that bending it will distort the holes. You might check for a fab shop that has a big press brake and die.

Re: Butt joint advice.

Can you tackweld to the boiler barrel, than heat it with a torch, work the torch around the boiler wrapping the strip as you go? Seems like the best ready made form is the boiler barrel itself. That's what I'd do, but I'd just use a pair of Vise Grips to hold the end. Heat it really red hot, go slo...

Re: Reaming vs. Drilling Holes In Tube Sheets

By the way, John Bailie designed a nice d.i.y. tube roller that works great. If you want drawings and info, send me a p.m. with your email address and I'll forward it on to you.

Re: Reaming vs. Drilling Holes In Tube Sheets

I didn't chamfer mine. I'd think you'd want the tube and sheet to get a good grip on each other.

Re: Reaming vs. Drilling Holes In Tube Sheets

Ken Schroeder, who has built perhaps a dozen boilers, told me that he just drills the holes and rolls in the copper tubes. He says he's had no problems with this. It sounds like it should make sense as the soft copper should be forced into the holes by the roller. I'd be sure to anneal the tubes bef...

Re: Allen Mogul, video question about cab castings

J B Weld putty, not the goop in the tubes. I've used that as a filler for other things and it works great. Easy to apply, adheres well, easy to sand, takes paint. I'd build up the side pieces, sand to fit, paint and move on.
