Thanks Ryan, I'd be in doing well on the motor mounts but fuzzy is an issue with some copy's of blueprints.
Monocoque Measurements
- Thread starter David Deschamps
- Start date
I'm after the height of the engine mounts in the chassis assembly.
Thanks Morten I have those drawings.
Ok, so which measurement do you need?
This is one of the motor mount drawings I am having a problem reading the numbers on ( fuzzy ). I have circled the fuzzy number and assigned it a capital letter , I know the drawing is in the book GT40 Uncovered. So having the fuzzy numbers revealed should give some of the motor mount dimensions I need.
Scaled and measured to my best ability in acad. I have a struggle making it correct in both directions at the same time.
Heres my result;
a 1,86 b 1,54 or 1,64 c 1,76 d 3,38 e 4,66

A is a function of the intersection point with the upper engine mount plate. I cant remember if this changes from side to side as the engine mounts are set back on one side by around an inch.
B and C are not that important as they need to be altered anyway to align with the lower face of the engine mount. there are additional returns that come off this point that align with the closing panel that forms the bottom face of the engine mount assembly. The corners of this lower face line up with the point formed by B and C so this can be cross checked. my point here is that B and C are an imaginary point that disappears once you add the rest of the folds in and is not noticeable in the final assembly as it is in space if I remember correctly.
D and E need to match and equal the measurements in the rest of the panels that make up the inside face of the engine bay. Allowance needs to be made for the sheet thickness offset from the mating face.

Thank you Tim , that is a great help.
Looking for location of the steering column bolt holes on the chassis . I have the CL measurement of the column.

Pic 2: 360mm from bolt center to floor on mine
Thanks Morton , that will keep me busy.
