Body Shell "Centre"
Body Shell "Centre"
This may sound a bit wierd, but does anyone know where the "Centre-of-Gravity" line is for an FB/EK shell (sedan) sans everything. I've just borrowed a rotisserie for my project FB and would like to move the shell through 360 degrees along an axis through the centre of mass from end to end. If perfectly balanced, I should be able to position the shell at any angle and leave it there. The shell is stripped of everything that can be removed, all external metal (including doors, guards, bonnet and boot)is bare with the exception of a wipe-down with fish oil, and now it's time to attack the underside and do some rust work on the floor.
Thanks Sammy. My plan will be to make the attachment brackets between the shell and the rotisserie with multiple holes running on vertical channels, so adjustments can be made. My concern is that my starting point, or initial estimate is close enough so that the shell does not tip over and cause damage. When I find the central axis, I'll share my findings.
Worthwhile is seldom easy
if mounting to the firewall of the hinge brackets top of rotiserrie or pivot sould be 100 mm above vent and 1220 from floorat the back mines a ute pivot is level with the gunnels and 1220 from the floor if you look on fc site under fatboys old school ute you will seethe rotiserie i made for the ute
cheers fatboy

Thanks For the Tips Guys,
Tim- Looked at the pics, looks like yopu've put the axis level with the drain pipes in the firewall. If this is close for a wagon, then I soppose I'd expect a sedan's to be slightly lower.
Fatboy- If I'm reading your description right, then it'd put the pivot within the turrett (above the dash) 1200 above the floor is in the vicinity of the roof
Ratbox- I must be a bit slow this morning, It took three looks before the penny dropped. Rotisserie, yeah very funny
I am however inspired by your work which is truly amazing considering how much is done outdoors.
Sheds are good; 1. they provide shelter and 2. they are a good place to hide.
Perhaps I'd better post some progress pics of my own, those of you who are in the Vic club will alredy be familiar with this project, as I've included it as a regular feature in the newsletter (Twin Fin).

I Did it!
Found the horizontal (Lengthways) centre of gravity for an FB sedan body shell. As seen in the pictures, the front centre is 250mm below the lip where yhe vent cover sits, and the back one is level with the edge of the boot lip.
Also I just wanted to show off the rotisserie, and say how much fun it is to be able to work on the sills, the underside or the roof always at a comfortable height. It's also easy to clean the crap from inside by just tipping the car on it's side and letting it fall.
The front is attached using Uni Strut welded to form a "V" which fits into the diagonal for the sub frame and to the bonnet hinge bolts. The rear attaches using heavy angle welded to form a "L" to attach to the bumber mounts.


Don't you just love that bare metal look?
Hope this is good for anyone's future reference.
