And if that Coles pump casting kit sees a rebirth, you can provide your drawings to the new business!
Doing your part to help preserve this hobby.

Re: Train brakes for the little Mogul

Greg: That's one of the photos I was remembering! Thanks for dredging that up. Frightening possibilities. I was taught to fire and engineer steam locomotives by Jim Norvell, an old Great Northern Engineer. He was pretty definite on how things should be done, and always explained the safety reason. I...

Re: Cole's Worthington pup question?

Dianne: If - after these discussions - you are still willing to share your work, I am hoping to acquire only a hard-copy print of the 2D drawings. I don't need the electronic files. I only wish to replicate the existing drawings. And I'll happily reward your hard work producing them! I'll send you a...

Re: Train brakes for the little Mogul

Another reason the prototype railroad steam engineers would release the engine brakes while applying the train brakes, was to prevent over-heating the locomotive's driver tires. These tires are heat-shrunk onto the drivers. Heat them too much and they will come off! This happened mostly with tall-dr...

Re: Cole's Worthington pup question?

Dianne: I don't have an answer for you (sorry), but I have that Cole's pump kit and plan on building it in the "medium future." So... Are you willing to share your CAD drawings? I'll gladly cover any costs you incur, to get a copy. The original faded print I have is barely readable! Perhap...

Re: Derailment - crash bars

Good timing on this discussion and photos.
My new small Mikado sits close to the rails and I've been considering options for derailment protection.
Thanks to all you posters for the ideas.

Re: Belpaire Boiler for a PRR G-5

Marty:
Inspiring to see your work.
I like the looks of the Belpaire boilers, living in former Great Northern RR territory. Added complexity to construct, though.
Thanks for sharing.

Re: Inexpensive DRO

Mr. Ron: I used the magnetic scales on the mill DRO package. VERY easy to use, including cutting to length if necessary. The 4 scales that arrived with the kit were all the correct length. I installed a Grizzley 2-axis DRO on my 14-40 lathe. It required careful installation to prevent twist damage t...

Re: Torque at different temperatures

Shall we assume the torque specs are for dry un-lubricated threads?
