So I salvaged the matrix as thats fine and dandy.
Took measurements of the resistor wires to replace with proper resistors (apologies I cant remember the values of the std wires but they are on here in general somewhere if you use the search function )
Found a coaxial blower on Merlin motorsports site (http://www.merlinmot...oduct_info.html)
And got on it.... SLOWLY
A piece of 2*4 (well ok 47*100(ish)mm)) square edged timber came to call for making the 'spacer' to represent the matrix, then a piece to make a taper from one side of the matrix to a hole sawn piece for a hose outlet. Similar was done for the other side of the matrix but didnt include the spacer plate.
The initial idea was to vacuum form the thing but alas no where wanted to do it for less than £100+vat per unit and wanted a big order... twats. And my matey was hard to tie up with
So GRP was the next answer but being a at the whole concept it took me a while to sort it out, and of course the weather needed to be acceptable.
I used some non llllloyds approved resin, some combination mat, some tissue and 50mm Kevlar tape for the job. Oh and pikey release agent of vaseline and tin foil (tin foil liner to the grp to keep some heat in)
piccys. OBV the items need tidying up and the matrix mounting then bonding the other side.
not bad for a 'first' go at making shizzle in GRP, the Kevlar is round the outlet pipes to add a little extra strength

worth considering with doing all of this, to improve the pipe work as well. Best solution I have found is black drainpipe connections. 2 60degree bends and a straight covers all will need.
total pipework reroute as nothing will lineup anymore

Interesting forms...
Are you planning to use the "footwell holes" as heater outlets?
Iinteresting site for you: http://www.cbsonline...heatac-95-c.asp
(They even sell a universal aircon module that looks like a fit for a VX/Elise )
Bugger the heater mod, get 2 of these from them.
One for the windscreen and the other for the rest of the car

The air will be going back into the cabin the 'normal' way. IIRC the footwell holes vent straight to the steering rack area and no where near the heater/battery compartment.
The footwell holes are located between the steering rack tube and the lower tube, so a direct path to the battery/heater area..
I'm still thinking of using this route for better heating.

that would require boxing in so to speak to stop cold air getting in... tbh its easier to tape the holes up and use the regular heater feed imho.
Matt, I read that the woven stuff can delaminate, but since its not under a lot (any) of stress I cant see why it would? and aslong as the tissue underneath dosent leak it will still be airtight
If it works well then I might knock a few up with either straight CSM or try going all kevlar as its not 'hugely' expensive although its a slut to hold the resin while curing.

Shes not pretty but a little attack with the flap wheel should see it looking tollerable.
note the extra filler (the brown stuff) on the top for the pipes.... I school boy errored and got the pipe holes the wrong way round
The filler is ace, its a polyester resin with glass ground into it and its bright green in the tin and goes that browny colour when its set... saves poking it to see if its done
