Oh well.. respiratory protector i think is not hard to find in HK. As after the SARS, we still have some N95 face mask at home.. haha
Ya I know... I just didn't wanna point it out, could be sensitive topic for some ppl!
But i have a problem getting 3mm CF at reasonable price. I did saw 2.5mm CF selling in HK, the price is even higher than a finished chassis! Specially TAMIYA parts are very very cheap in HK
CF sheets is not something you'd easily find retail.
Depends on who you know, try out either aviation or motor racing workshops. The airplane guys often use flat sheets for their fabrication and might be able to sell you some offcuts cheaply. Sometimes in Oz we can find pieces about 30x50cm for about $50-60, enough for about 2-3 chassis depending on how fat your design is.
As for EvoIII... if you don't mind the shape of the current chassis... why not just bolt TWO of them on?? Haha, was thinking about that the other day, had 2 chassis plates on my table & just dreaming... 5mm thick! hahaha... except I'd probably want longer screws and gee, my rideheight would become about 2mm.
I haven't tried cutting anything recently, but when we did CF & FG yrs ago, it helps prevent splintering if you sandwich your material between 2 thin sheets of plywood. Clamp it all together then cut using a jigsaw (think it was the fineteeth 'for metals' blade).
Have not tried using a router like Steevo... would be good idea if your bits came free, but router bits are very expensive otherwise.
With jigsaw... plan on wearing out 1 blade per chassis, assuming it doesn't break prematurely. Also when drilling the holes even highspeed steel drill bits goes blunt quick. You need 2-3 bits to do all the holes nicely... so maybe invest in a drill bit sharpener. A drill press would be very important.
Given all that... haha, I don't have the patience anymore to make own chassis plates - better to buy. I do like making my own stuff though, but prefer to work with aluminium.
