Re: Allen models Fitchburg Northern build by first timer

Same cylinder castings, same situation a few months ago. I ground out one of my stuck core wires with a small carbide burr. I saw no residual sand in mine. If the cast-in ports don't clean up exactly to print make your valves to fit by adding or subtracting from the print numbers as necessary and ke...

Re: Welding

As rkcarguy said, I too have to make sure the central air or clothes dryer aren't running if I'm going to push my older Miller Syncrowave near its upper limits. I got tired of getting in positions (too old) and using the foot pedal with a knee or elbow so I broke down and bought a thumb reostat for ...

Re: Welding

I agree with those saying "take lessons", get taught. Learn the processes, materials and when to use them properly. Learn to recognize problems. If your welds haven't been destructive and/or non-destructive tested at some point don't hang your life on a bead. Practice, Practice, Practice. ...

Re: Modeling Corrugated Sheet Steel

A quickly butchered together experiment last night showed me this is what I can do- I'll use my 20 ton press as a simple press brake with a single 18" long round nose male die and matching female bottom die, though the shape of the bottom die isn't too critical. It can even be hard rubber/ureth...

Re: Modeling Corrugated Sheet Steel

Hi Chris, The largest scale corrugated I found was 1/12 for doll houses. Saw the YouTube videos earlier and have the ability to make a sheet metal roller but was trying to avoid that if possible for a 16" x 18" sheet. Other videos/methods for HO and O gauge buildings don't much apply. Than...

Re: T-shaped brass

Not sure what size you need but Online Metals carries brass T-Bar, it might be too big for your needs.

Re: Mich-Cal 1.5 Shay.

Hi RR Ty, On my CP173 I used all Model Taper Pipe fittings with -hard- .032 wall copper tube. Any tight bends in the copper were annealed first. On my current build I'm doing the same. The main reason I go this route is I simply like the grittier look of cast pipe fittings on a steam engine. .015 wa...

Re: Modeling Corrugated Sheet Steel

Thank you Adam, I've seen the stuff and forgot it existed. For a cab roof it will need some backing for strength but that shouldn't be difficult to do. As my second loco build I'm building a Chloe detailed out as a way-way-back, backwoods logging engine with no particular prototype in mind. It'll be...

Re: Modeling Corrugated Sheet Steel

Thank you guys. I do have a dividing head, cutting splines isn't an issue, I would need to build a roller. I thought about ball and corner rounding end mills which I have but every corner rounder of mine has a large center spud that forms the full radius, it would have to be heavily modified. Thinki...

Modeling Corrugated Sheet Steel

Has anyone modeled corrugated sheet? I'd like to come up with a way to make enough 2.5" scale sheet for a small cab roof. It only needs to be one sided but somewhat durable. The best I can come up with is grinding a form cutter and milling the corrugations one by one in 3/16 or 1/4" alumin...
