Hi Cyco-Dude,

Thanks for the kind words.....

For the duct, I used thin plexi from Home Depot. First I made a duct out of light cardboard, taped together. Once it's shaped right, I transfer the pieces to the plastic. It's like 1/16" thick, comes in small sheets. Easy to cut, just score it a few times with a utility knife and snap it off at the edge of a bench. It's made for picture frames, has like a frosty side and a glossy side depending on what side you look at.

I sanded the joints to rough it up and used Epoxy to glue it together. I used tape to hold a couple of parts together, then put some quick set (5 minute) epoxy in a couple of spots. Once it sets, I painted the seams with more epoxy.

But then.... I found out from a plastics guy that epoxy doesn't work so good with plexi or lexan. It holds as long as you don't force it. They make chemical bonding agents that fuse the stuff together, like a PVC cement almost. He said that over time my plexi water reservoir could start to leak, so I took it out in order to redo it. I don't want any surprises a couple of months down the road. I got some of this chemical cement ordered from this place, going to try it. http://www.modernplastics.com/ It's called weld on #16 cement. I never researched this acrylic stuff before but should have before making this stuff.

I am close to done. I finished cutting out an aluminum panel to fit over the Dig Doc5 and am having a friend machine out the holes in the front cover. Then I can get it anodized and put together.

Hi jaydee116! Thanks!

EDIT:

The duct out of case.
