Re: Technology is great

Besides, why would you want to deprive yourself of listening to the screeching noises coming from the band saw as it cuts through thin tubing? :D Whir, whir, whir, whir, sccreeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee, whir, whir, whir, clunk! I do still have to cut up a bunch of 1/4x3 flat bar to make the ba...

Re: Technology is great

standParts3.jpg Here's a video of the 9' long rail tubes being cut. It's hard to get good video because of the UV shield around the head of the laser. https://www.youtube.com/watch?v=kACHR1_3kXg kACHR1_3kXg Over the next couple weekends I'll get these welded up. I'll post more as I go along.

Technology is great

A while back I brought all my rolling stock home to work on and they've been sitting on the floor in the garage. Pain in the butt! I decided I needed a couple roll-around stands for them so I sat down and designed a stand in CAD. I work for Ryerson and we have three tube lasers at our facility so I ...

Re: Building a Power Model Water Pump

My injector is English style, but I cannot confirm its origins. It was in a box of random bits and pieces that my father picked up at an estate sale of a gentleman in TN that passed away in the mid 1980s. It works on and off, up to 80psi, but catches a lot of trash in the cones and quits working. Th...

Re: Building a Power Model Water Pump

This darn thing is still sitting on the workbench unfinished. I really, really need to get back on it and get it on the mogul. The English injector I have on the fireman's side right now is pretty much useless and I need to get the pump done. Married life, career change, and various other things hav...

Re: Delrin and Journals

What? Delrin... Plastic?!! I thought we were building a steam engine here.......... Cast iron, bronze bearings, STEEL!!! So, I suppose you're also opposed to 3D printing a boiler? :lol: Please don't give anyone that idea... I cant even imagine... "Surely this sintered material will work, right?"

Re: Standards and common practices

Myself and quite a few others in the CSPPRY use Tom Bee brakes on our rolling stock. His system uses 1/4" poly tube between cars with Schrader valves on the end sills. These are positive pressure brakes. Application pressure really depends on the weight of the car and trucks; I have three pieces of ...

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...
