Re: Building the 2.5" Scale Shay

Tristan, thanks much! I should have asked also what is your boiler diameter? Looks like your bore diameter ratio is slightly over 1/5 th cylinder diameter. (1:5.32) I’ve read elsewhere - somewhere- that geared locos require generally greater nozzle diameter and steam jet flow than conventional engin...

Verifying Blast nozzle height

Hello All, This winter, I’ve decided to see if I can improve the steaming characteristics of my 12” ga Ottaway (coal fired, 12” boiler) I’ve have now two years experience firing the loco, around a very short 430’ backyard track, having a 130 LF downgrade. So perhaps not ideal for maintaining steam p...

Re: Building the 2.5" Scale Shay

The second, and biggest improvement was changing the blast nozzle. I started with 9/32, which was found to be too small. The exhaust went from beats to a roar going up grades and back pressure was robbing the engine of power. So I bought a brass pipe plug to play with while the stainless steel one ...

Re: Bow Hill RR

May actually be a digital decal of some sort. In any event it’s a great backdrop to the Porter.

Yes, couple of sheets of painted sheet metal, maybe a sheet of plywood by the door.

The tracks outside the building are actually a mural, Painted on the doors.

Bow Hill RR

Visited the Bow Hill RR today, just a few miles south of Bellingham, Wa. Motive power is a 24” gauge, immaculately restored Porter, 0-4-0 loco, with new code boiler and new good as new tender. The owner will be putting the RR up for sale in the next year or two, as he and his wife get ready to downs...

Re: 0-6-0 L9 Switcher, differences

Ryan, For tight radius turns you could also consider a geared loco, such as the Heisler, or Shay. The trucks pivot like freight car trucks so have a much sharper turning radius, plus tremendous traction. Rated for 6% grades in real life. Something to think about. BTW, I like the Mallets a lot, also....

Re: Draft plates

Daris, Very timely question for me. I actually have draft plates on my antique Campbell 4-4-0 (circa 1904) loco. Just looked at them a few days ago when I started stripping the lagging and plumbing off to test the boiler. Apparently these were standard equipment on full size locomotives. I didn’t kn...

Re: New Books On Sir Arthur Heywood's Railways

Mike, looks very interesting! can you say how many of the drawings relate to 4 wheel boogies, rather than the two wheel carts? I’ve been searching for drawings of early style 4 wheeled passenger cars in 15” gauge.

Thanks,
Glenn

Re: Run out of steam pressure after 100 feet

Alcosteam, those were my thoughts also. I think Nicholas might be in Nevada. So, Could be 80 or 90* F there when he shot the video. If so, he wouldn’t get so much visible condensation as where he running in a colder climate. But, the steam has to go someplace! Looking forward to more info concerning...
