Re: Building the "Lilly Belle" Boiler

Harry,

Just curious why you didn't use a slope sheet? Original plans or personal preference?

A Live Steam Project Comes To Life

I wanted to share the first breaths of a live steam project I have been working on full time for the past 5 years. This locomotive, the Baldwin Locomotive Works #26, has had every part inspected and reworked or replaced if necessary. All brought back to original specs and a few pieces better than th...

Re: Shop Press: When do You Stop Pumping?

Sorry for the delayed response. On my orange 30 ton HF arbor press, I have already replaced both movable table support pins that sheared off with 4140 pins, replaced the top bars with a solid section piece after the bowed out to the sides, and, replaced the schedule 40 pipe arbor that the jack press...

Re: How Many Flutes for Wood?

I use single or two flute cutters (end mills and form cutters) on my CNC mill to make all kinds of stuff, from foundry patterns, wood forming blocks for copper bashing, and wood window and door rosette plinth blocks. The key is to hone the edge dead sharp, as in peel your fingernail sharp. Climb mil...

Re: Pipe threads in brass/bronze?

I like to use Moly-Dee on stringy naval and aluminum bronze. It keeps the brass from sticking to the die teeth and tearing the threads. I also keep my new dies for brass and the old ones for steel. For a tapered thread, it's always best to taper the part being threaded, especially with the fine MTP ...

Re: Service animals on railroads that haul the public

The handler of the "service animal" should have a certificate, registration or ID. They are allowed to ride our trains. See http://www.ada.gov/service_animals_2010.htm for a description

Re: Is there a prototype for these trucks?

Turn of the century? No. But the do resemble Isothermic bearing housings. Within the round face, a paddle sloshed oil up to the top of the bearing. the Boston and Maine was a fan of the Isothermic housings. At one time the B&M 3713 had those on her tender trucks. BTW , they are not roller bearings.

Re: Mitutoyo indicator rebuild

The biggest, or should I say smallest, issue with dropped "Mitties" is the anti backlash spring. They are super delicate and once the indicator is dropped, this super flimsy clock spring type of anti backlash setup gets all tangled up around the shaft of the anti backlash gear assembly. I have succe...

Re: Dumb question - cleaning up castings

Flat files, sanding blocks and paper, and wood (yes wood) chisels work well at removing cast surface imperfections. A beat up wood chisel can even produce a wood grain like surface texture in aluminum castings by dragging the sharp but nicked edge along the flat portions. Tiny pin prick marks can be...

Re: Smokebox Design

This is one heck of an interesting conversation. I would like to throw a little bit of coal on the fire (pun intended). In the late 1930's, Lima's superpower locomotives had cavernous smokeboxes. The smokebox on the full size Pacific I am currently working on is 10 feet long from the door to the tub...

Re: Eliminating chatter when turning a boiler tube

Stuff the tube full of rags. Or get a big blob of modeling clay and make a round log and stick that to the inside near your cut.
