I'm thinking on ordering HDPE to make my DD sled, including tubing for the all thread to pass through.
I'd done a couple hours research on adhesives for HDPE and have come up a little short on affordability.
Has anyone bonded HDPE to HDPE?
Solvents was mentioned in several findings, but nothing specific.
We use ethalene dycloride in junior high to bond plexiglass pieces together.
Other than that, I have done nothing like solvent gluing.
Why HDPE? What properties are you looking for in a AvBay sled that would require HDPE?

The reason I ask these questions is that HDPE is heavy and very difficult to bond, Fiberglass sheet or even 1/8" birch ply are easier to work with and do a great job, Even Polystyrene (stuff plastic models are made out of) would work.

I second using FG or birch ply boards. they are not expensive, and do provide solid mounts for expensive electronics...
I didn't think HDPE was that heavy. It can be drilled and tapped.
Guess I'll look at the plywood route.
Thanks for the input.
Birch Plywood is available at most hobby shops and is usually the Midwest brand name. I use 4-40 Tee-Nuts and epoxy them onto the ply sled, the tee nuts are available at most hobby shops that sell R/C, my local Hobbytown USA is where I get them, they are Great Planes brand.
Personally i switched to these, have not found 1 bad thing yet....

These are a complete awesome thing! he designed in a battery holder and switch holders, they are even custom made for each altimeter.
He makes some great sleds, as well covers for the Mobius, etc. rocket mounted cameras!
I like the looks of the Etsy products.
This might be the easiest way to go for me for the first one.
Thanks for sharing!
