In all my time in the Army (I’m retired from the Army since 1996), I never saw a ridge pole for any “GP Mediums”, as these tents were known. That’s not to say that ridge poles didn’t exist, I just never saw one nor did I ever hear of anyone talking about such a thing.

As I recall, the poles were all hardwood. The pins and collars were as you describe. I honestly don’t recall for certain, but I’m thinking the two tall poles used up to the ridge were two-piece poles. I seem to think there was a collar attached to the top of the lower pole half into which the bottom of the upper pole slipped into. But again, I am not certain if I am remembering that correctly.

I believe the poles were octagonal in cross section, so you should be able to make that cross section with a 45-degree router bit or even with your table saw.

As a resource, you may want to at some of these on-line manuals:

https://www.scribd.com/document/217149358/TM-10-8340-240-12-P-MGPTS-Tent-Manual-2005

They look like they are all more current than my service time, but perhaps they may help you. Or you can just search on “GP Medium Technical Manual” on Google.

Hope this helps. Good luck!

Cheers!

Dave, first of all, thank you for your service!
Second, thanks for the information and history of the tent. I’m excited now look thru your links and begin working on the tent poles!!!

Jeff,

Did you ever figure out what to do about a ridge beam?
The BSA Troop that I am a volunteer for has recently been gifted a GP Medium Tent, without poles and the adult volunteers restlessly building and gathering poles, but we are short a ridge beam.
So as I am wandering the internet and I stumbled upon this post, I figured I might as well ask about it.

Thanks for your time,
Logan

Logan, WOW What a great gift!!

I ended up making my own poles for the entire tent. 5’-8” poles for the sides, 6’-3” poles for the door opening, 10’-3” poles for the ridge poles. As for the Ridge beam, I found it to be optional.
Take a look here for original military specifications for that tent as well.

http://www.liberatedmanuals.com/TM-10-8340-211-23P.pdf

The way they setup the tent ridge guy lines, they provide the “stretching” needed to support even a snow load.
This PDF even shows the original staking diagrams to maximize the strength of the internal strapping.

I am still doing minor repairs to my tent like fixing the corner zippers, patching small holes/tears. I am actually toying with the idea of making a wooden door like you see on the TV show MAS*H .

My hunting buddies think I’m bonkers…

Also –

Eave Poles and Ridge Poles before stain


I needed a couple new corner brackets to replace broken ones, made these so the middle cross-bar has a slit, and a sliding piece to close the gap after attaching the strap.

I’ll get pictures of the poles this weekend, but to give an idea…we used some natural lodge poles and some modified lag bolts, we also sealed the bottoms to help mitigate any possible weather and natural exposure damage.

Nice job! Looks very good.
