Re: Nusky/Mercer 0-4-0 driver width?

If it was I making an engine to 7.25" gauge, I would make the flange and Back to Back as per the Greenly Standards, and the treads wide enough to run on 7.625. I'm faced with that as a debate point, as dad has a 7.25" gauge loco that I am waiting to find out if I can get away with 7.525" gauge track...

Re: hydrostatic oil

So, oils like TK460 (Chevron) will mix with water- that's the point of them being a compounded cylinder oil. Oils like Mil-L-357 (Steam _turbine_ oil) don't form emulsions with water, and are used in applications where there will be condensation into the oil, and you want good separation properties....

Re: Topic For Discussion

Marty, Can I suggest following the adjustable foot arrangement as well? It is a little more work right now to do so, but it means that the track is leveled rather than having to level the ground? I think it only means the weld for the nut on the tube, in that both the foot and the top are welded alr...

Re: Topic For Discussion

Interesting. I brought home the other section of the original Niagara Interlake RR yesterday from a private owner. It is a 400-foot loop complete with supports. Apparently the Art Ellis track was split into two in the foggy mists of time and TSME got one loop. Probably because TSME has the first se...

Re: Topic For Discussion

Dan, I would have to agree with you. Something like dad's Dart (Built by Harry Allen), in 7.25 is a small 7.x loco- it's still something like 4x the weight of my Brit, or Caribou. But, if you set it up somewhat sensibly, it could be carried in the trunk of a regular car. (getting it in/out might be ...

Re: Topic For Discussion

It's the naysayer's, saying Nay !. Dad just had the TSME track arrive at his house, both clubs here have/or are building a 3.5" gauge line (BCSME has been at it since about 2000, but keep running into lack of will, I think, based on the mileage of 7.5 on the ground and ongoing maint) A 3.5" track ca...

Re: Calculating boiler size

What I have done is create some spreadsheets to ease the calculating burden onto the computer :) Generally, what you are going to do is figure out how much volume your cylinders have, then how much steam you are going to use per revolution, then how much water is required at the operating pressure (...

Re: 1.5 SCALE LAYOUT SOFTWARE

OK, so I had a look on TEMPLOT, and it will likely do what you want, with the notable exception that it is not to be used for building an actual railway. (as in, you are using it to design a railroad, and they are not responsible for your choice of actually constructing a railroad...) It has been us...

Re: 1.5 SCALE LAYOUT SOFTWARE

For designing what part of it? I would suspect that CAD would be the best way to do the ground layout. If you want track design, I am not sure, but TEMPLOT may allow you to do sleeper layout/angles/ect for the track. But in short, I don't know of anything special to design ride on railways for a bac...

Re: Covid Creations

Good slope on the last 10'. Like 1:10 or more... (UPHILL, you jokers !) :D I've done it here, done it at dad's old place, he's going to do it in North York. I've got a date booked with my local digger guy for some more work around here as well as some of a 40 yd pile of dirt that is supposed to appe...

Re: Air Pump D Valves

Even if it is $150/ft, and you use what ? 3" let's say...well, I know that if I put in more than 4 hrs work into the part, that my pay is more than that...and that's as a power engineer, using work's equipment not mine... So yes, a $40 piece of material is "annoying" in the expense account. But if i...
