Roundhouse 40 Foot Bay Extension for Two Bays ---
I
had a request from a modeler that had a few longer steam locos that
wouldn't fit into the roundhouse with its 105 foot stall length. Kind
of surprised me as I think a Big Boy would fit with out the tender. I
spent a day working on this and was able to cobble together an
extension using some of the existing walls. I probably won't be
printing this myself as the longest loco that I have and probably
will have, a , just fits. So please if you print this let me know how
it worked out and if possible take pictures and send them to me and
I'll post some. I'll also come back and post pictures here when I get
to this stage if I ever print this out for myself ( contact20 (at)
purplesagetradingpost (dot) com ). This is a long print so I won't be
printing it myself and at this point have printed all the pieces on
the preceding pages so another reason I'd like to know how it goes if
someone does print this.
One
aspect of this I'm not real happy with but won't spend any more time
on as it isn't important to me and I'm not making any money doing
this and have lots of other things that are more important is the way
the loco ends up at the back of these extended bays. It is close to
the wall side of the loco when it is in the bay. From my calculations
and using Fusion 360 to mock it up (see picture further down this
page) a loco will clear the corner where it enters the extended bay.
Just make sure the crew that moves the engine in for service doesn't
need to work on that side of the loco ;-).
Once
printed you just replace any two back wall sections with this print.
I'd make sure one of the bays is lined up with the track that goes
straight across the turntable and to the entrance track to the
turntable on the other side. That way if the loco is too long for the
turntable you could line the turntable up with the turntable entrance
track and the track into the bay. The loco could be pushed or pulled
in real life it need straight across the turntable and on into the
stall. Of course this would only work for one of the two bays unless
there was a second track to the turntable on the far side for another
straight route to the bay.

The
extension adds 40 feet to two bays.
.
The
extension replaces what would have been two back bay walls.

There
is only one file associated with this bay extension ( 1-Back
Extension.stl ).
Please
if you print this let me know how it worked out and if possible take
pictures and send them to me and I'll post some. I'll also come back
and post pictures here when I get to this stage if I ever print this
out for myself ( contact20 (at) purplesagetradingpost (dot) com ).
You
can find the print files for these floor sections that you can use to
make the floor or for patterns ( HERE
).
=========================================
NOTE:
This concludes the files for now (01-25-21). I'll probably work next
on roof supports.
