Neil, we can't just go down to the local speed shop/race store over here so we have to improvise but in saying that LSR is something else, no matter where you live.
I ordered a special board with a melamine surface I could use as a table top to mold stuff like flat honeycomb panels.
It was a big board and took up space so I decided to cut it into sections that would make it easier to use.
Yesterday I started on molding the panel that would become my radiator box.
It should be a large cross shaped piece that would get routed and bent into shape much like a cardboard box.
Clever me!!!!
I cut the board 5" smaller than I needed. What was going to be a two step operation turned into a mission.
Measure twice, cut once.
A few images of the process.
