Re: Attaching the smokebox

The Central of Georgia tenwheeler that I rebuilt for Mike A was secured with three stainless screws around the periphery of the smokebox into tapped holes in the boiler shell. This is how it was originally built so I kept it the same. I gave those three screws a good coating of anti-seize before the...

Re: Need Expert assistance

That's a rather large question. More specifics would help with answers. Steam supply lines are typically 3/8 pipe. Injector lines are typically 5/16 tube. Blower line is typically 1/4 tube. Etc., etc. Of course, there's the entire category of model pipe as well if you're looking to build as close to...

Re: Attaching the smokebox

A trick I learned from Don Fite (Dan has the same idea) that I used on my mogul was to weld tabs with threaded holes inside the lip of the boiler and brackets with through-holes in the smokebox. I used stainless cap screws to tighten the two together. This pulls the smokebox and boiler nice and tigh...

Re: Allen Models making changes.

I'm huge fan of water-jet parts... The rods are a perfect candidate for this process. I would expect water-jet to cost more that laser cut. Anyone have info on relative costs? The water-jet I had in my University shop had high consumable and cleaning expenses. But they surely work wonders. ~RN I wo...

Re: Allen Models making changes.

I would offer the rods in steel for a couple reasons: 1. Strength 2. More appropriate look/finish 3. You can have them cut in bulk either via laser or waterjet for a reasonable price and the customer is buying a part that requires less machining and finishing than castings. I, too, am one who threw ...

Re: Question: parts for a steamer

Harold, I agree with you. The inability to run coalburners, together with the distance (for me) makes it very unlikely that I would attend or (especially) bring equipment. There's just so many great tracks that are closer that I've not been to, and which I would rather visit. I'm not saying I disag...

Re: Reaming vs. Drilling Holes In Tube Sheets

The two boilers I've built both were drilled undersize prior to welding. After welding they were reamed out to size to fit K copper flues. I did not chamfer the hole, but rather used a sandpaper disc to deburr the inside and outside faces of the tube sheets before rolling the tubes in. End result wa...

Re: Access to Tender Tank Inside

I made the top of my tank removable. As built I had used phillips head screws. When I finally had to take the top off I had a lovely experience cleaning out those screws to get the screwdriver to sit down in them. I have replaced them with slotted screws that are easily cleaned out. The top of the t...

Re: Just picked this mogul project up off of DLS

If you can get the 516-70 for 10% over A36, do it! As for plasma cutting, have the parts cut oversize by .060 (if the shop is quoting +/- .030 tolerance). Easy work with a grinder to take the edges down and get rid of the heat affected zone. The HAZ won't affect your welded edges as much as it will ...

Re: Another New Guy wants a 10-wheeler

My mogul pulls very well, despite not taking the other half of that lead sheet from Don Fite -- yes, he still has it in his shop!

Re: Just picked this mogul project up off of DLS

I'll chime in a bit on the alloy selection. While 516-70 is the best choice for these little boilers, you are absolutely OK with using plain old HR A36. The deciding factor is typically availability and price. When I built my mogul boiler I was able to get 516-70 in 1/4 and 1/2 for the firebox and f...
