I doubt any would break if solely used as a pinhole camera.
That is what mine ended up as. Ultra light weight but since I had enlarged the hole in the 65mm plate for a M42 mount helical I couldn't use their included pinhole so I jury rigged my own. The helical had a too narrow opening to field the full light cone from the 90 Angulon and it wound up in another project. I've retextured the plastic GG and it has served me well on other u-build projects. Removed the fussy to load metal spring back and use my own design. Looks cobbled up but works great and is secure and easy to flip and change film holders.
So, all in all, I've used many of the parts that came with it. Unlike yours mine had hard focusing right from the start and finally became unusable.

From the view of a company like SK Grimes, they are totally right and I didn't expect others.
The main problem for repairing is not the task herself. It's the base, the camera body, who makes things difficult.
The given space for trying to make something better than original is approx. zero.
On the other hand, doing the same like the "engineer" of this camera would be worthless.
At the end of this week I probably present my solution.
I tend to cover the original parts with cone aluminium parts to get half a millimeter to one millimeter more space for the screw borings.
After doing the repair, the weakest area then will be the original nuts of the camera, but we didn't hear about any problems with this area, and my solution will not change anything there.
If not overtightened by the customer, this seems to work fine then.

Re: TravelWide Repair Question
Sorry - for some reasons, I am late.
Last days I made a CLA to my machines.
Today i started with some measurements for creating new stuff out of aluminium.
Re: TravelWide Repair Question
Good luck!
The attachments don't work, though!
Re: TravelWide Repair Question
Thanks, Steve,
I made some new adjustments to the pics , I hope this will work now..

The attachments work now, thanks.

Re: TravelWide Repair Question
Thanks, Robert.
Today I rounded some "layaround"-metal with my Boley 4L; I wanted to find out how many space is given between camera body(inside) and the later new part.
Measuring only gave me no parameters for sure.

Unfortunately there is absolutely no useful space.
Here's a tiny nut melted to the body (inside), with a thread of around 1mm:

Re: TravelWide Repair Question
The TW guys wided the body a bit, for giving space to the Mickeymouse ears of the broken part:

Here you can see the body with my metal ring inside;

Crazy.
No space.

Body, metal ring, original part:

My initially idea, either to cover both the broken parts with an aluminium ring, or to build a bigger sized aluminium ring, will not work.
The last thing what I wanted to do is simply copying the original part ( and having way more difficulties and time issues in doing the job), but I haven't other ideas at this moment.
The given situation is everything but perfect :-)
So I prepared my mill for tomorrows making a copy out of aluminium.
This way I will get an idea if the copy would be good enough for longtime-fixing the helicoil of the TW.
See you,
Ritchie
Re: TravelWide Repair Question
Thanks for the illustrations. It makes the dificulty of doing a repair/improvement very clear!
Re: TravelWide Repair Question
I would drill new holes to my own TW body, or milling the body a bit wider - one millimeter each side would be useful.
But this is no solution for an "easy-install"-repair kit.
Fortunately, the original srews are tiny, and they don't require much force for fixing the helicoil, so a copy of aluminium should work fine.
But as a mechanic, this "wrong way"-solution doesn't feel good to me.
But who cares about my feelings while shooting with the TW :-)
