Bonnet fit

PostPost by: davidallen » Mon May 16, 2005 2:51 pm

Hi,

The bonnet (hood) fit on my +2 is horrendous, even worse than the doors and
that is saying something.

The worse area is in line with the carbs/exhaust where it sags below the
wing edge by at least 10mm.

All the paint is off the car, so now is the time to correct the fit, but
short of building up the bonnet by a large amount which would not be very
practical, I cannot think what else to do.

Any suggestions?

Ta,

David

David,

I'm not quite sure where the bonnet does not fit, but you should check the following.

Are the front bobbins in either/both the bonnet or wings worn ? If so you need to repair them

There should be some adjustment in the domed pins that engage with the bonnet catches. If not you might have to remove the bonnet catches and relocate them higher on the bulkhead.

The problem is corners of the bonnet face line up, within reason, with the
wing corners, so moving the bobbins/catches will make matters worse.

If you can imagine, the curve of the bonnet between the corners is a greater
radius than the curve of the wing and consequently it sags in the middle.

I know the Plus2 is a fair bit different but curve on the bonnet of my S2
varies depending on how tight the springs are at the front. It seems very
flexible and never lines up properly. When I paint the car I intend to
glass some metal ribs onto the underside to hold it at the right shape.
Don't see why that wouldn't work, anybody else done this?

David,

On my 1968 Plus2 there's a steel tube across the leading edge of the
bonnet, with fairly thin but wide steel 'arms' attached to it on each
side. They extend back almost to the rear corners, and are riveted to
the bonnet sides. They should stop the bonnet side edges from flexing
vertically (I'm not sure if this is the same on later models).
Maybe yours are bent or missing?

Cheers,

Ron.

Yes, I have the steel tube along the front, and the "arms" but they only
extend back about a foot. The bonnet is pot riveted onto them.

Should these be longer? They would certainly help the bonnet retain it's
correct shape. I wonder if they were shortened to prevent the driver being
"speared" in an accident?

What about other members cars?

Yes, this is a box section onto which the catches are mounted.

From memory, it only runs along the windscreen edge of the bonnet.

On your car, is this connected to the "arms"?

no......it sounds like you have all the relevant under bonet steelwork in place......
have you thought about adding a central steel member say attatched to the legs of the front frame and then lifting the bulkhead catches.....but I cant understand how its lower at the edges....the edge should be the stiff part of the bonnet and in theory shouidnt sag....
what about sticking a pic on the elan.net?....then we can all have a look......or even a brief video clip.....
cheers

Hi,

The bonnet fit saga continues.........

I had a look at the workshop manual last night, and the steel arms on the
front bar are shown extending nearly to the rear of the bonnet. However, on
my car they are only approx 12" long.

Could someone with a +71 elan +2 please let me know how long their arms are?
It could explain why my bonnet has sagged in the middle edge edges.

The question is how to how do I get a good fit? One possibility is I cut
through the vertical sides which would allow me the bend the bonnet to the
correct shape. I was then planning to hold it in place with ally strip
rivetted in place while I glass over the inner edge. Is this practical? I
don't wish to cut slots in the lip just to find I cannot bend the bonnet!

Thanks in advance for any help.

David

Mine are 13 3/8" overall, which takes them almost to the middle of the bonnet.

David,

My 70 Plus Two originally had short strips, extending just up to the bonnet prop pivot. Many years ago, I noticed stress cracks starting around this area. I reinforced this side almost along its complete length with a strip of 16 gauge 18" x 1 1/2" pop riveted insidecthe edge, undernath the original strip. My 68 Plus Two (restoration job) has a box section frame all round, definitely overkill, it will have to come out !
