[R-390] Replacement panels [was RE: R390-A Paint Formula]

[Barry Williams]

Yes, a good printer will have scanners big enough to lay on, so size 
isn't a problem. If they charge more than a few bucks you are being gouged.

Some software will find the lines of the letters and generate the CAD 
files. I used to cut screens and screen print for a living, but it was 
all cut by hand or photo screening. I'm sure there are better methods 
nowadays. A silk screen is simple enough.

Ralph Sanserino sent me a front panel once and it arrived without 
damage. I later mailed to a guy for a swap on some tubes. Just get 
cardboard of a reasonable thickness and cut it oversized by 2-3 inches 
around the panel. Put the panel in the middle and use plenty of 1/4" 
staples all around the seams. Maybe add an extra sheet of cardboard to 
each side, but I don't think we did that when my panel got mailed around.
