I have a few details to round out,
but the bellows looks like it should work.

I'm expecting a roll of TPU filament on Monday, we shall see...

So I just found something to occupy my free time.

I should be able to use this to scan my HO scale articulated cars,
and create panels to slap onto the sides of my G scale passenger cars to convert them.

I have HO scale diner/kitchen/coffee shop articulated, mens/womens passenger articulated, tavern, baggage, etc.

Unfortunately MTH doesn't make any of these in Gauge-1. :f:

While non-production of given models is aggravating,

you do get to create this adventure out of the thing.

And the diaphragm bellows you created looks grand.

Printed 2 vestibules with the flexible TPU.
Typical "1st attempt" issues, de-lamination, etc.
But I don't think this design would ever be flexible enough...

Did some research and found that the Daylights also had an outer vestibule,
meant to maintain the streamlining look.
The G-scale cars don't have it, but the HO do.

Go to this page and scroll down to "Diaphragm Adjustments" to get a visual.
My next attempt will be to make something like this outer vestibule.

Been very busy building outdoor track.
Be sure to see the finished trestle on page 8.

But I digress.
I picked up my GS4 last month and the wheels fell off. :bang:

As installed, the motor block swivel bracket was severely pinching 2 motor wires.
The pressure this put on the bracket appears to have caused it to crack,
and this crack caused the stud to break off.

There is what appears to be a clearance slot for the wires, but it is on the wrong side.
The swivel stud is offset from center,
and there are 2 indexing studs on the mounting side to insure proper orientation.

So I concluded that the slot was put on the wrong side when the mold was made.
(I could be wrong... )

:dope:

Opened up my 2nd GS4 and found it had the exact same issue.
The stud hadn't separated yet,
but the plate had a healthy crack extending up to it and continuing up the stud itself.
The wheels would have fallen off soon!
And 2 of the 4 mount holes were also cracked by the sheet metal screws.

After attempting to contact MTH parts and getting a robo email about "out till at least Sept. 1"
I decided to roll my own!
Note that I moved the clearance slot to the proper side.

1st pic. is the bracket before I removed the insulation.
The insulation was so squished you could see the wire thru the remaining very thin skin.

2nd pic. is the bracket showing the crack and missing stud.

3rd pic. is my prototype for a better replacement.
It will take a few more passes to get all the dimensions exactly right,
but this one would work as is.

I've ordered some M2 bolts and taps.
I plan to drill and tap the holes instead of using those sheet metal screws they force in.

Hi Steve

With all that snow in Colorado ...

... I guess it's indoor toys for you these days ! :cb:

I hope that the 3D-printed loco repairs are holding up well. :brill:

& more importantly ...

... your repairs to the Moose Defences ! fences !!

:moose:

Good luck !

:java:

Si.

Si,

I finally received the replacements from MTH,
but they still have the wire slot on the wrong side.

I think I will use them first,
but after filing out the slot on the proper side and tapping the holes for bolts,
NOT the sheet metal screws MTH uses!!!

I bought myself a new camera body for xmas,
and am spending all my time learning to take panorama photos.

I want to master the technique well enough to shoot a 360 degree panorama photo set
(it takes about 24 photos stitched together with software)
on the Winter solstice from my observatory.

I can then install this panorama into my astronomy program,
giving the "feel" that you are inside the shell when using it.

The new camera also does video,
so it will be useful for documenting the Beaver Lode RW,
as I continue new work next Spring.

Steve

Hi all,

I finally got around to finishing the repair of the GS4s.
I hadn't had much incentive with the weather as it is...

Tapped the motor mount side for M3 bolts,
and the mounting stud for an 8/32 bolt.

Seems fine.

But the more interesting 3D-print project of late,
is a negative holder that I made for some odd format
(somewhat larger than medium format)
negatives I found in the attic, of an old house on the site.

Not the holder itself,
but this picture that was among them.

I believe it is San Diego either immediately before or during WWII.
The above link is to the full sized image, approx. 12MB

Here's a thumb:
