sticky stuff
A mate of mine has just built and MK indy With a ZX9 engine in it.
I waw it for the first time on Monday night, and there was something not right about the frint cycle wings, i just couldnt put my finger on it and
then..............there are no external bolts hlding them on!
He said Martin K said he can use some of their special bonding stuff to glue them to the support brackets! He also said he can do the rear arches with
it too.
When my mate asked what happens if they come off, MK said we will give him some more free of charge.
Anyone else used this stuff, if so what is it called? and have you had any problems?
it seems too good to be true.

Colin,
Absolutey no help, but having just made my front arches, the intention is to laminate the bracketry under another couple of layers of f/glass.

Arches very simple.
Decided how close I wanted them to be to tyre (1/2" ish). Tyre radius 11.5
Took two pieces of MDF and scribed the shape on, then cut slot into MDF with jigsaw.
Then ally sheet slotted into cuts. The ends needed some bar (used 12mm) to stop them bending out. For the curved sides, I took a piece of 3mm ply and
scribed round an aerosol lid, and cut off/sanded that smooth.
In the female buck, I carefully put plaster in the corners and shaped with former.
Greased, gelcoated, matted, demoulded.
Here's a diagram to try and explain better

Panel Adhesive
Col, the adhesive to which you refer is made my "evo" as in "Evo-stick" as well as a number of other suppliers under various
trade names. It is basically a polyurethane adhesive/filler. Guys in the know will be very aware of it's capabilities. The type I have seen is
called "Tekflex", I believe there is also one called "Secaflex" prices vary wildly so be careful. There was a stall at
Donnington selling it for £7.50 a cartridge. There's a place in Barnsley (where I'm going tomorrow) sells "Evo" for £6 other
stuff for £5 per Cartridge. But, I've seen it at £15... it retains elasticity to a degree once set, but requires a pneumatic chisel to remove
it! It bonds almost anything to anything.
I'll post the number of the place tomorrow for the rest of you's guys, together with accurate prices.

Polyurethane Adhesive
Isn't the other one called "Sikaflex" or something?
Anyway I got some from Screwfix. They sell it as Rapid Polyurethane Wood Glue. I think it's the same stuff. Very very sticky. If you get it
on your skin you'll have to wait until it wears off as it doesn't come off easily. When applied to surfaces it "foams" after
a short time and sets within 5 mins.
Screwfix order number 11972 - £5.99 for 310ml cartridge.

Steve,
It's been because of all the useful tips you have on your site that I actually decided to have a go.
As all my shapes are reasonably straightforward, I decided that it would be easier to make "female" bucks, rather than have all the
trouble of proper buck, mould then original.
So it's all your fault
Thanks for taking the trouble to write it up.

Not quite the same - the sikaflex stuff (and all the other PU mastics) looks like silicone bath sealant, usually grey or black. Dries to the
consistency of hard rubber and sticks like the proverbial to a shovel.
The stuff you're talking about is only a wood glue, albeit a bl**dy strong one!

Nice to know it helped someone - I just bought a book or two, read up on here, and got help from alanB, chrisG and syd bride and others.
I thought id write it cos there didnt seem to be a comprehensive cohesive set of guidelines anywhere.
It was written in some respects to stop people doing what you did! If I could buy the bits i'd hit my credit card and take the pain!
Good on ya for taking the 'did it myself' route.

Sikaflex is used by coach builders to cover a multitude of sins like panels that drum etc. They just stick a piece of 2x2 timber to the back of the
panel with sikaflex. A similar but slightly cheaper alternative is Tiger seal, usually available at body shops.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
