Hello Dan 

I had very good luck building a cover for my Lehman with the Plexiglas sold 
at Home Depot for replacing broken windows. Use one of the tool they sell to 
cut it into pieces for the size box you want. You can make a nice neat box by 
putting a piece of 1/4 X 1/4 inch wood in the right angle corners of your 
box. Find a hobby store that caters to adults who fly radio controlled 
airplanes. These stores carry a lot of real handy stuff for fixing the planes 
when they crash which sometimes happens. In this store you will find four 
foot lengths of 1/4 X 1/4 inch Balsa wood. While you are there buy some 
Cyanoacrylate Glue that hardens in 30 seconds. Get the gap filling type. Glue 
a piece of this wood to the edge of the Plexiglas where you are going to make 
a right angle corner. Put (not too much) glue on the strip of wood and place 
it exactly at the edge of the piece of Plexiglas where you want it. After a 
few seconds you can't move it so make sure you get it right the first time. 
Now put a thin line of glue on the other side of the wood and press the other 
piece of Plexiglas in place. If you are careful you should end up with a nice 
neat box for your Lehman. If you live where a hobby store would be far away, 
you can get the stuff you need from "Balsa USA". call them at 1 800 225 7287 
Most any hardware store sells Plexiglas and the tool to cut it.

Good luck,
Cap
