Re: real NG trucks

The frames are composite, oak center with 1/4" thick steel side plates; that goes back to the 1880s Pullman plans, which the D&RG appears to have copied. Some of these trucks were in service at least until the 50's, and the 053 car still had wood brake beams in some photos.

Re: real NG trucks

One of those weeks when a bunch of things finally came together - that pile of loose parts in the container got a bit smaller. Hope to have two pairs on the road in a few more sessions. The pair in the photos needs to have the brake beams hung and then ready to paint - after a final check for loose ...

real NG trucks

Here are a few pictures of a set of passenger style trucks destined for car 053, an ex RPO now serving as a cook car to a rotary snowplow train on the Cumbers and Toltec. There is also an earlier vintage set under way for an 1889 coach and a set of steel frame ones for RPO 54. Between the three pair...

Re: Tesla cars

Most interesting, My grandfather was a consulting electrical engineer in the early 1900s and he drove an electric car- did lots of battery experiments on battery materials and optimum charging cycles. I have a whole pile of his patents around here somewhere including a few international ones.

Re: Drilling Concrete

Gravity type retaining walls commonly have an 8:1 or 12:1 batter or slope. Beyond the keys, no additional interlocking is required. Additional layers behind the wall should not be required. If you are based on a rock, that should be good. Perhaps a concrete wedge to set the angle. Gravity walls are ...

Re: Drilling Concrete

On the deadman topic - strongly consider leaning the wall into the loads so the pile of dirt will tend to push it upright. Otherwise you will have a leaning wall. I am not in favor of walls build on soft foundations - a hard foundation gives you a much better chance at controlling future movements a...

Re: Shaper forum??

I have a 12" Gould & Eberhardt that is old enough to have poured in-place babbit bearings. I put a new gear rim on the bull gear many years ago. One of those tools that is nice to have but rarely used. I have been offered 24-36" shapers just for hauling them away as shops needed the space for modern...

Re: Narrow gage wheel sets

Not the kind of grinding you were thinking of; they do posses a tool post grinder, but the stone on it might have been chipped out of a medium cobblestone. The shop supt started there at age 17 and just celebrated his 50th anniversary in the shop. Shop probably was set up in the mid 50s as the local...

Narrow gage wheel sets

A local shop is currently making some wheel sets for the Cumbres and Toltec; four sets with 3 3/4" journals and Muley ends, and four sets with 4 1/4" journals and conventional ends. The wheel chuck in the four jaw is 26" nominal. Wheels are new steel and the axles are 4140 annealed. The wheels are f...

Re: Pinched rod ??

Most likely it was made with a hardened steel die in a press. You could make something similar that could be used in a vise - two jaws of a hardenable steel with the correct profile - some sort of alignment pins or frame, and insert rod and squeeze.

Re: RE: JET JVM-626

I found a riser block essential - always trying to get a big part into too short a space. My riser is 12" long and 16" dia - on a Gorton 1-22. For small parts I have a rectangular block that goes under the vise, and I have a riser block for me too!

Re: RE: JET JVM-626

When we made risers for a mill, we added a number of reinforcing ribs inside the riser, not uniformly spaced. Made it a lot stiffer and not subject to any one frequency.
