Hi,

Is it necessary to rivet the dashboard former to the scuttle or is it acceptable to use bond only?

If you can get it to stay whilst it cures, fine, but there is a bit of load on the hoop as you will find, so it may not be practical.

we use counter sink rivets at the very edge of the skin, The edge trim, which you will have to have, hides them, if you want to be super professional, you can counter sink both sides, the pull part of the rivet will then expand into the sink and you can file/grind the face flush that side to.

We usually finish by bonding all the joints.

Thank you Simon.

Can we use 'normal rivets' and slightly counter sink the holes?

counter sink rivets, or standard without counter sink, they do not mix well

I have seen blogs that have the dashboard former bonded only, so might try this method. Anyone else tried this? any suggestions please?

My scuttle wanted to deform so couldn't see anyway other way bar rivets to hold it all together.

I think if you have drilled the mounting points on the chassis it should be ok as it will be held perfectly while the bond cures. If not, you will have to find a way to hold it while it sets.

From experience, the trick is to get the former shaped exactly to the form of the scuttle, without any gaps being evident between the two parts with no clamps or pressure applied (you might need to fold, then un-fold the tabs to achieve this, but keep this to a minimum).
Also ensure that the flange which supports the dash panel is on a flat plane.
In this scenario, the former should only need bonded.
Then abrade both surfaces and clean using cellulose thinners to provide a key, this will give the sikaflex the best chance to adhere strongly. Use clamps to hold in place but don't over-tighten.
Best done on the car so you ensure symmetry etc.
Hope that's some help....
Cheers

Personally I would rivet - the former does have a mind of its own and is one piece I found a pain to fit - I imagine using bond to hold it in will be a struggle without a lot of patience, co-operation from the former and a lot of clamps.

for doing the scuttle I found it was worthwhile leaving the scuttle bolted to the chassis and ratchet strapped down for a week or so to get the metal to assume the shape naturally - when you then release the scuttle from the chassis applying the former is a little easier as there is a natural shape to follow - work middle out do one side at a time and take your time, it is fragile and as I mentioned earlier takes on a mind of its own particularly when you get to the sides of the scuttle which is where I had the most issue fitting.

Its a job you need a lot of patience for!Laugh

good luck - be interested to know if you did have a go at bonding though

Thank you for your reply Laney.

Good idea to bolt and strap to car, I will try that.
Think I will rivet now as just offering up former to scuttle without rivets would be very difficult to get it right.

Cheers.
