Chassis bonding adhesive
1st thing, I'm not trying to bond a tubular chassis together.
the chassis on my Haldane suffers from what i would call excessive scuttle shake so i wondered whether i could brace it by bonding some strips of
steel to it between the rails, using the stuff lotus use, then i could bolt or bond the bulkheads to those.
I'd like to avoid welding if at all possible due to access, plus dropping the fuel tank etc.
If it's feasible does anyone know where could i get some from and would it cause problems at MOT time due to not being welded ?

is it the scuttle that’s shaking or really the steering wheel support? once the dash is fixed on to the front then the whole scuttle becomes very
rigid.

Scuttle shake is not really the scuttle shaking as such  It's a lack of torsional rigidity in the chassis which causes a kind of
'wobble' in the car, particularly noticeable when you go over bumps. Common in convertible versions of saloon cars whose stiffness is
compromised when the roof is removed.
As for the original Q, can't help with where to get the glue though, sorry. Unless you know someone who works for Aston or Lotus.

No, I know what you mean but the dash on mine isn't the same.
it's not a 7 but the advice on this site seems to be the best around that's why i'm here.
there's a support behind the dash from side to side to sort of stiffen up the fibreglass scuttle but that isn't fixed to the chassis and
isn't meant to.
It's basically a piece of 3/4" plywood glassed under the bodywork
the steering column is solid, i made my own frames up to spread the load, one onto the transmission tunnel and floor the other to the support i
mentioned
I'd just like to fix the chassis and body together in more places than the manufacturer thought was enough.
My mates westfield gives a much comfier ride
Got it matt, just what i mean

Methacrylate should do the job. Available from RS among other sources. Also, the 2ton epoxy solves a multitude of problems.
Lotus stuff needs a big oven and a good deal of heat. The chassis stuff, anyway.
Cheers,
Syd.

oh I know all about scuttle shake, the Falcon was blessed with more than enough to make the dials unreadable 
Think I have now sorted that out

How did you sort it ?
I'd read somewhere that JBA had a decent chassis, obviously not, i can still read the dials
Matt, you described the condition perfectly
i just want to try and improve it.
Syd, could you give me a bit more info regarding suppliers please ?
