Model Shapeways Tank Car Frame


Steve and Barb Hile
 

Just curious. Is anyone else still working on the early UTL tank car with
the parts from Model Shapeways?



I have posted several more pictures of mine in the Photos section. This has
turned into a project not unlike building a resin kit. I made tank bands
from 1x2 strip styrene with a short length of styrene rod glued to each end.
I curved them by pulling them across my thumb nail, as you would curl a
ribbon for a gift wrapping. The guy who designed the casting included the
nut on the underside of the tank saddles, but you need to drill it out a bit
from the top side to accept the rod end of the band.



I was going to use the ladders from the MDC car, but broke one when I glued
it in the wrong place. So the ladders are modified from the Tichy Tank Car
Detail set as are the handrail brackets. I discovered that the Precision
Scale tank car kit contains two sets of castings for the brake wheel shaft
brackets. Since they mount somewhat offset to one another, I put a piece of
scotch tape on the PSC tank end to mark where the holes were and then used
that as a template to drill the holes in the MDC end.



I think I am done because I can't imagine drilling some 20 number 80 holes
into the sides of the running boards to mount 8 hand grabs and the coupler
lift levers.



All and all, it was an interesting project, I am sure that we will see more
usage of this kind of construction. There are still some bugs, the castings
were more brittle than the good resins that we are used to and ACC does not
grab rapidly on this surface, but will hold eventually.

Steve,
Good photos and nice looking car. Is it as fragile as it looks? Did you have to forego any coupler centering mechanism?

All in all, it is pretty sturdy. The material is a bit brittle, but not too
bad.



Yes, I have no centering for the couplers, I have no idea how that will
work. This is mostly a display model for me.

Very nice work!
Question: are those Tichy parts supporting the long grab irons along
the tank?

Thanks. Yes, the handrail stanchions are from the Tichy tank car detail
set. In hindsight, I might have been better served using the PSC brass
ones. In trying to rebend and reuse the MDC handrails, I ended up with
three pieces that were a challenge to get on, and straight. Oh well, live
and learn.



Next up is paint and decals.

How do the Shapeways parts look when painted?

Aaron Gjermundson asked:

Aaron, the Shapeways masters shown in the photos (underframe and multiple dome structure) *are* painted. Otherwise you'd have a hard time seeing the surface detail. As received they are translucent white and slightly sticky due to residual wax. After ultrasonic cleaning in hot (but not uncomfortably hot) water with a bit of dishwashing liquid added, they are frosted. I sandblast, not to clean, but to even out the surface finish. Shapeways Frosted Ultra Detail material, unpainted, has a chemically active surface. It takes paint readily, but silicone rubber will bond to it. You won't be able to get an unpainted Shapeways master out of the mold without tearing the mold or breaking the master. Usually both. That's why, with Shapeways, I order two of everything.

(Forgive the overexplanation, but Aaron is an accomplished resin caster and I want to save him some grief.)

Sorry, I missed the point that Aaron wasn't asking about the ATSF tank car frame.

Thanks for the compliment and the explanation, Tom.

I was really vague with my question, I was about to pack up the laptop before driving home from the NP show in Billings.

Was referring to the parts that were used in the type X cars that a number of you were building. Has anyone finished one yet?
