Lexan Preparation.
The lexan pieces have a protective covering that needs to be removed before assembly. When the laser cuts, the covering melts into the cut edge which can make removal difficult. If you gently scrape the cut edge with a flat blade screwdriver, the covering can easily be lifted and peeled off.

On smaller pieces the coverings can be more difficult to remove. If you have trouble you can gently scrape the cut edge, then use duct tape to lift the covering off.

For further information on lexan, see this page.

Lexan Preparation.
Step 1.
Attach the hex spacers as shown, using 3/8" screws. The top four spacers and the one in the middle are 1.5"; put washers in between the these spacers and the lexan. The other four spacers are 1.0" and require no washers.
