The backpack of backpack builds

... Well, not necessarily :)

So, I started my pack obviously. I actually built two frames, before settling on a third (below). I wanted something seamless, and so I built the one shown below. I riveted all the corners together for added strength, I also used a Bondo-like material to fill in all the cracks on my pipe fittings. I'm considering a plastic coating over the entire frame as well.

Frame #3

Just a bit more work to do here

Aluminum bars for attaching the seed trays to my frame

Stinger in progress ... I might swap the cone out for a more accurate part.

Some updates on the pack...

I ended up making the box for the exhaust port out of a display case for an old iPod shuffle. I used ABS sheets for the back and triangles. Right now I'm sanding the Bondo, and coating the inside with some resin to strengthen it a bit.

Still had some parts drying on the exhaust port ... but I attached everything on the top section. The bottom section is still obviously in the works... attaching the stinger next. I also have to order my 2 1/2" piping from TAP plastics... same stuff I use for my TK thermal detonators kits.

Thanks guys!

But I don't think I mounted the mortar tube right, so I'll have to fix it. :P

I'm vacuum forming my own end caps and control panel for the mortar tube. I'm also having my own Radio faceplate 3D printed, hope to be getting that back in a couple weeks.

After that, it's just the radio assembly, and the straps ... I think? Oh and the weathering. :D
