Re: Safety valve location

In our models the pressure is essentially equal everywhere. The drypipe intake opening should ideally be located at the highest point in the boiler to avoid priming, thus the existence of domes. There is no rule stating such, and for every rule there are exceptions, but I favor the boiler shell loca...

Re: Safety valve location

If not dictated by prototype or obstructions, I'd locate safeties in the last "course" (or section - if any) in front of the firebox.

Re: West Virginia Coal down South

Burning coke at MSLS . . . . this took place 30-40 years ago and was a result of the beginnings of deteriorating coal quality and a trackside spill. I don't recall the mix they finally settled upon, but certainly some experimentation was involved. It could be hard on grates if you overdid it and in ...

That's certainly the case . . . after all, both are musical instruments.

Re: Machining a bell for better tone

Just one more misstep in my life. I don't think of it as a mis-step. It's probably one of two things . . . It's not economically viable for him to make up alloy in a batch of less than 2k/lbs, or He just wants you to go away and not bother him. I was once told to go away and not come back (at a fou...

Re: West Virginia Coal down South

That's interesting. Decades ago, when live steamers in the South began using Pocahontas, it came from #1 and #2 and was considered the best we'd ever seen. Some years ago a cornfield derailment near one of our members left a supply of petroleum coke on the ground which was harvested and mixed with t...

Re: Best wood for footboards?

Oak is an obvious choice, attractive, wear-resistant, plentiful, relatively inexpensive, at least in my area, but it has a drawback - it's naturally acidic and will corrode steel and brass. I use Red Oak in the workshop for lots of things, for its hardness, but I never allow it or its dust to sit on...

Re: Little engines 1" line of engines

Dick, That was a ball park figure we once used to estimated the production time on architectural working drawings. Some sheets took less time, some longer, but it turned out to be a surprisingly accurate estimate and it's proven to be a decent estimate of model engineering drawing time. What it does...

I'd wager that a whole lot of those sets of plans probably got thrown out by someone who didn't know what they were
Without a doubt.
I knew of several such sets, one of them for a LE 1" Atlantic built by a friend of my father.

Re: Little engines 1" line of engines

It's very curious to me why with so many hundreds (if not thousands) of drawings, individually or in sets, sold for the LE 1" line are now so scarce? I've got a few sets of orphaned drawings which floated my way (on the way to the trash bin?) which I've hung on to because I thought someday someone m...

Re: Two cylinder beam engine drawings

I was waiting to see if you had any response, and I hoped you would. In the meantime (as no responses poured in), I was thinking one alternative would be to reverse-engineer the castings and develop a set of new drawings. That would take some time, and the usual knowledge to do it, but it could cert...
