The bolster that started it all was the Old Style AtlasO 100 Ton Roller Bearing Truck Bolster. I designed it as a copy of the Atlas parts, just narrower. In fact, with these bolsters, it takes the Atlas truck to EXACT prototype width. The problem with THAT is that only the Protocraft modern 100 Ton Roller Bearing axle sets are long enough to protrude from the frames enough to put the rotating end caps on, and then, only just barely. Here is the link for the Protocraft axles:
And here is the link for my bolster:
This is an early version of the bolster, and it used the detail plastic in its creation. I don’t recommend that as it is fairly brittle (which is very undesirable in a truck) and more expensive. This is also a very early version of the AtlasO Roller bearing truck, with cast on bearing end caps, not rotating ones. If you have this version of the truck, then you can use the following axles from Protocraft:
Since the axle ends don’t need to protrude, the shorter axles will work just fine.
The axles you see in the above photo are, in fact, NWSL 33″ axles, not 36″. The truck in question is a 100 Ton truck, thus it should have 36″ axles, but at the time, that’s what I had and I used them. Now, I prefer Protocraft axles, but I will discuss needs and the issues with the NWSL axles in future posts.
Again, if you want to order directly from me, the cost per bolster will be $15, plus shipping and I will inspect and clean up the bolsters before shipping them. Please contact me at firstname.lastname@example.org.
