In this Lexan project
I will walk you step by grulling step in how to use lexan as a Chassis matterial! This project is for Rustlers and Pedes, but the info can be used in any project using POLYCARBONATE
Let's talk TOOLS
! Now you can get away with using the basic hand tools like Jig saws, hand held drills, and circler saws. If you go this route your work will look weeellllll not so nice and not work as well! Now if you really want this project to turn out RIGHT! Then the proper power tools to have on hand is: Hand held Drill, Jig Saw, Table saw, Scroll Saw, Table Top drill press and heat gun. These tools most people don't have, but if you look around you may find someone who has one or alll the tools you need and may be willing to let you borrow them. Please follow all safty rules and use safty equipment when working with power tools.
Let's talk POLYCARBONATE
! Most common question is How thick to use and where to get it! Now Polly comes in may thickness, sizes, colors, and prices! Just look in your yellow pages under plastics or sign shops or try the inter net. under Polycarbonate
! You should find many places that sell Polly! Now, how thick? that's really up to you but i like to work with .220 or 1/4" thick matterial. and I get a piece over 2'x2' For your first chassis that should give you enough matterial to play with and leave enough for misstakes. As you get better you will use less and less matterial when making chassis.
WORKING WITH POLLY
! Now Polly is a soft matterial that has a low melting point! So Drilling and cutting the stuff takes CARE
! Cut and drill slow taking out a little matterial at a time. Example, If your drilling a 1/8" hole through a 1/4" thick material 2" deep, and you start drilling with out backing the bit all the way out every 1/4" to 1/2" to let the bit and plastic cool this is what will happen! Your bit and plastic will heat up causing the plastic to start to melt then the plastic for some odd reason cools quick durring the drilling. Then the drill bit becomes fused with the plastic and drill bit and plastic becomes one! and the plastic gets riped from your hands causing injury to your equipment and YOU! Remember to watch the plastic's temp. The plastic shavings are a good indecator durring the drilling and sawing of the polly! Are shavings are soft and hot! Just cut and drill slow!
! Design, Design, and Design. Plan what your going to do first! Measure twice or three times before Cutting! This saves Money!
Now we are ready to make our first chassis! The next in stallment will do the Lower chassis! Any Questions Before we continue

Good God, I hope I haven't OFFENED any one yet!
