Striders Backpack build with found parts

178 posts in this topic

It's just a bit over a year that has passed since my last pack build but boy, this year has seen quite a bit of new discoveries. I felt it is time to build a new pack, the move along this time, and to try to incorporate those new discoveries. So let's do it :)

First thing for me was the backpack frame. Now we all now it's "The" vintage Karrimor frame. But is there really just one model? I was lucky enough to come across an old boyscout from the UK who happended to have a nice collection of frames up in his attic so I persuaded him to sell his "collection" to me.

I found that they did not only come in different lenghts but also with different thickness of the bars. After some eyeballing and photoshop scaling I found that 0,76 inches (diameter of the bar) looked right:

Again, after doing some measuring I found that the pack should actually be a little shorter than the ones build during the last year. My last pack had a lenght of about 60cm but 45cm looks more like it.

The next challenge was to find appropriate seed trays. After spending quite a bit of time on ebay I actually found them; real vintage seed trays that not even look like the ones used for the original packs but also have the correct dimensions. They only had the 3 rib ones but afaik the only pack that actually comes with a bottom seed tray that has 5 ribs is the move along pack.

But since I planned to do the move along pack, some modding was in order:

The upper seed trays are no finished yet (still need to fill the holes) but this is what they currently look like:

For the radio I was not lucky enough to snag one on ebay so I decided to model one with the correct dims and details with a help of fellow Sandie (Thanks, Redbeard!). The radio holders on the side are actually cast from originals :) Below you can see a comparison shot with a found radio:

Some other original parts I will use are the Shires syphon, a Gio Style canteen flask and the 4" tupperware lid.

IMO the (wet wipe) bottles have a larger diameter than the ones frequently used. By my estimate they should be in the 9,5-10cm range. I'm using a 1,5L shampoo bottle. The lenght will definitively need to be reduced but I'll do that when I had the chance to do some test fitting together with the other parts.

However, since none of the mushroom caps currently offered are wide enough, I asked Redbeard again to help me model and print it in 3D which I usedd as a base for my mold.

EDIT: During my build I discovered that they've indeed used a rubber plunger for the "mushroom cap" (link provided in the thread).

I vac formed them in black ABS (along with the exhaust port):

That's all for the moment, hope you guys like it so far :)

Thanks, guys!

@Airborne Trooper: My plan is first to finish this build and to confirm the hypotheses on the measures. After that we can speak about doing a run for those parts :)

Thx, bro. Well, I think I might do an interest thread on all the parts I'm making for my pack and if demand is high enough I would do a run on those parts. But first I have to find the time to finish it :)

Thanks, bro. Updates coming up soon! I've managed to find an original 'tool box' and 'mushroom caps' and will reveal what they actually are. (Yes, I do like to tease, lol ;-)
