Re: Conical Boiler Casing

I do a lot of things "just 'cause" I want to see if I can do it. And it usually works out OK.

Re: Conical Boiler Casing

PS - I actually did the volume calculations for comparison between doing a tapered section and just a straight tube on a typical "wagon-top" boiler to determine how much volume would be lost. On the projects I had to hand that turned out to be a negligible percentage. This short-cut might not be app...

Re: Conical Boiler Casing

On the few boilers I've been tasked to build (copper) which required a tapered course (a "truncated cone") I determined that the internal volume lost was insignificant compared to the time effort and cost of doing a short transitional taper. I built the boilers with straight barrels cosmetically hid...

Re: Driver machining order

The problem with turning the front and rear faces of a rim on the axle (in models) is that often there isn't enough stiffness in the axle and spokes to avoid deflection which can create harmonic chatter, even if taking the weensiest skim cut. An on-the-axle skim on the tread usually goes off without...

Old Model Engineer Mags - Sale Pending ****SOLD****

I have the following Model Engineer magazines which are free for the cost of shipping. They are old and yellowing, but they're all sound and in very good condition. Interesting reading, from another time and place. There are runs of sequential issues but the sequential runs are random within the yea...

Re: Passenger Car Maroon

I guess it would boil down to what it would look like using a researched or "historic" color, vs. what you think it should look like. Color is an elusive thing and each of us sees it a little differently. If it were me I think I'd take the Floquil swatches to a paint store to see how they compare wi...

Re: Recommendation needed for copper boiler repairs

Keith, given the locomotive and its age, and lacking any other information, that would be a reasonable assumption to make for the sake of discussion.

Re: Recommendation needed for copper boiler repairs

I agree with Dan. The age of your American suggests that it's boiler may be built using a phos-copper solder AND LE's cast bronze 1-pc firebox, which even in their best years were known to have solder-repelling inclusions and porosity. In fairness, far more of these firebox castings (also used on LE...

Re: Anybody recognize these parts?

I'd say you've guessed right. The long narrow castings are Walscheart valve gear frames (in R & L halves) and I would assume the smaller castings close by are frame mounting brackets. I wouldn't know for what locomotive model.

Re: Regauging pressed on wheels

All things considered, I think that while I was at it (and after 115 years) I'd go ahead and install new axles, and eliminate the worry I might break a wheel. If not, it would be imperative to bear the entire force of the press on the hubs.

Re: Purpose of False Valve Seats

I've used valve face "inserts" (my terminology) on two locomotives. In the first instance it was to save castings with poorly placed steam passage cores. In the second instance it was to enable better design and easier machining of steam passages where there was no coring. In both instances the valv...
