The Glareshield is made from 10 mm MDF. Except for the glare wings, which are made from 12 mm MDF. Most of the time I spend planning this part. You have to keep the dimensions of your electronic parts in mind (MCP, EFIS, Fire Warning). I dont have any electronics yet. So in case of doubt I calculated free spaces a little bit bigger to have enough room to install them later.
In the Sketchup file you will find measurements included for all parts.
Thanks so much for posting this info and very inspiring, can i share it?
