Lifting Bonnet Hinge

[Alan Whitaker]

Hi All.
Been thinking of making a forward lifting front hinge , It would lift the front of the bonnet about 150mm up before tilting forward. I have a idea how to do it and was thinking has anybody ells thought of doing this.
Don't ask for a drawing as you won't understand my drawings

Hi Alan, I toyed with the idea a few years ago using a system similar to a double glazed window hinge. It soon became a nightmare tring to work out angles etc. What have you got in mind ? It would be interesting to see.

Alan,

There was a thread on something similar last year - if I can track it down I'll add a link.

I recall that there were mixed opinions on whether it would work.

Maybe some hinges that work on a parallelogram principle might work?

Or possibly a big swingy arm?


Think one problem could be that the bottom edge (valance) of the bonnet will catch as it comes up, maybe some kind of slots would allow it to pass the hinge mechanism


I copied (with a couple of small changes) this idea to improve engine access on my Taimar

Hi Mike
I see what you mean about the valance, just as well I dont have one then, I had to cut it back to clear the trans cooler and other bits undre there,

should be "a piece of cake" then



....... or how about hinging it windscreen end, Frog eye Sprite style ?

I remember from Sclub 2011 that JensW had a great bonnet hinge.
Here's a link to the thread discussing this.

I used the rear hinge method on my RS200 lookalike....worked fine....(the original is front hinged



when painted it looked better


yes it is front engined.....Celica GT4...4 wheel drive 300bhp and 1260kg

not an s but by making the pivot point high and forward the bonnet lifts up vertical with no lift up hinges as a could not make them work,

Hi All
I was thinking of a forward and up movement either by hand with some kind of lock when the bonnet is down or 2 electric rams, would give a 200mm forward and up movement, easy to make it's is it going to be manual or electric.

Classic Saab 900 has a brilliant 2 stage bonnet where it comes up and forward and then swings open. Google for a pic. Somebody cleverer than me might be able to adapt it?

Thanks for that I have been racking my brains thinkin that there was a bonnet that did that, of course it was the Saab.
Now I have that idea the Volvo 340/360 also did a similar trick.

Can grab pics/a vid of mine if anybody is interested. Really simple but really effective.

Hi All
Sorted out the automatic bonnet lift, electric rams and a key fob, the control unit will push both rams together so the bonnet will lift up and forward at the same time as going vertical. Just need to make some fixings.
won't be needing the stainless set I got from Norman?

I am after a SS hinge set if you are looking to off-load it. YHM
