Re: Triennial Unloading Video

[quote="Harold_V"]Hmmm. If what I've heard lately is true, there may be a considerable lack of live steamers attending future meets at TM. Indications are that they are now banning anything in the way of steam that isn't fired by propane. Kills any incentive for me to think of attending in the futur...

Re: Balancing engine

Good discussion of static vs dynamic balancing. When Jack Anderson and I (plus two other crew members) rebuilt Hillcrest Lumber Company Climax #10 (1981 at Mt. Rainier Scenic Railroad) it arrived with counterweights welded to the two crank discs. Climax#10.jpg We learned from Hillcrest's president t...

Re: Curved Links?

I believe the curved links matching the radius rod length produces the desired valve "lead", regardless of the position of the reversing lever (Johnson bar).
Someone more knowledgable please elaborate.

Re: Superscale safety valves.

SuperScale safety valves are even recognized by the Washington State Pressure Vessel inspectors as the finest available!
Verbally, not in print...'cause they are not allowed to officially make product recommendations.
I have two on both of my locomotives.

Re: Dave's Goose Project

Another question about trucks. I'm told they must be flexible to stay on the track. My test car did just that. Very flexible and it stayed on the track. Now the motor trucks aren't very flexible. Their first run is coming up soon. I'm wondering, are the drive wheels on the big steamers flexible? Wh...

Re: Coolant; to use or not to use?

I think the wax stick lube is the way to go. Saws are not easy to clean as the swarf get between the blade and wheels and guides. Water based coolants probably work well as they carry away much of the swarf, but as I said, a small 4x6 saw is not set up for wet sawing. I agree: I've used a wax stick...

Re: Slitting saw too tight to remove

My cheap slitting saw arbor has a center section machined smaller than the finished ends, which index into the R8 spindle. When the mounting cap gets stuck after making a cut, I hold the arbor in the vice, by gripping the smaller center section, thereby not marring the machined mounting surfaces. I ...

Re: Custom Lost Wax Castings - CAD Model to Bronze or Alumin

Thank you for the kind comments, Russ. But, I would like to point out that Steve Zuideveen took the lead on the improvements to the arch bar trucks. Even though he is no longer a partner in Allen Models, he wanted to see this project through to completion, and I thank him for that. We have agreed t...
