I have download the plans of book chassis & 442E in sevenesque, but it didn't give the size of the center tunnel which hold the gearbox & driveshaft, where can I find it?
http://sevenesque.com/plans/I downloaded the 3D files for those designs (also on his website) 2-3 years ago and I don't remember what format McSorely saved them in. However, I'm pretty close to positive I loaded them up in the free Dassault Systemes viewer, E-Drawings. When the file is loaded in E-Drawings, you can use the measuring tool in it to measure between surfaces, points, lines, planes, etc. It will tell you what the initial dimensions of the tunnel are in his layout. However, as advised here, the tunnel size you actually need may be determined by the donor components you elect to use in your build.
