With the engine mounts sourced it was time to figure out where they would tie into the chassis. I chose the right hand lower mount first as it looked like it would land conveniently on a chassis rail. I was worried about bolting the bracket to the 2”x1” tube so I carefully marked out the mounting holes on the tube and machined 2 threaded bosses which were welded into the chassis tube. The mounts used odd proprietary bolts with an in built locating washer so I machined some stepped buttons to accurately secure the mount against any lateral movement.
My wife and I took some very accurate measurements of the rear wheel and upright assembly. I then transferred the measurements to CAD and produced the 0.5 scale silhouette ready for the “String Computer”. If you’re not familiar with this concept its a method of cheaply modelling suspension geometry using a board and string line. Its outlined a couple of Alan Staniforths books on car design and builds. This will then allow me to site the inboard pickup points for the rear suspension and then ultimately build the rear wishbones. I’ll take an identical approach on the front suspension and modify the wishbones from my old project accordingly.
