i would go for 1mm polycarb, anything more go hdpe. reason being that it is very soft at 1mm thick (or thin!)

Which is why he shouldn't use 1mm

Spark is all 2mm armour, with a 5mm frame underneath

Deodorant is 1mm hdpe, bolted to 12mm hdpe

Yeah, nice looking ant you have there now. Only problem I'd remark on is it seems to need a more powerful servo.

I've always found the HPXF servo to be good, reliable as well as powerful

I'm using 1mm polycarbonate.

And this whole bot idea is in jeopardy. My Dad wants me to have extra French tuition, which I'm not accepting and I'm avoiding it at ALL costs. He's threatening to cancel this if I don't get the tuition, or at the very least pick my French reports up.

cancel what?

Lexan can crack when bolts or screws are used in it, Lexan must be allowed to flex, or it wont hold up to the rigors. The proper way to do this is to chemicly bond it together, with a proper resin.

polycarbonate has never, ever cracked on me

Badger · « **Reply #70 on:** July 25, 2011, 06:24:40 AM »

I was thinking of using screws forf a bit, but I've found some Lexan glue (Forgot the proper name), so I'll use that.

Glue gun works well :D

I'd still use HDPE though, not a big fan of polycarb

HDPE

HDPE is WAY to expensive for me, and I'm guessing that it's more difficult to work with than polycarb. Remember, I have no real tools.

Vertigo · « **Reply #73 on:** July 25, 2011, 06:41:09 AM »

HDPE is quite cheap actually

haz · « **Reply #74 on:** July 25, 2011, 06:42:08 AM »

yeah, at £2 a sheet its a right bitch.
lexan, no
macrolon, no
polycarbonate, yes.

yes i do know they are the same thing, it just anoys me....

Badger · « **Reply #75 on:** July 25, 2011, 06:42:50 AM »

Not as cheap as polycarb, I don't think so anyway.

But it's better that polycarb, IMO anyway

haz · « **Reply #77 on:** July 25, 2011, 06:45:14 AM »

cheaper. its just the postage from direct plasics is high - you have to buy 45million sheets just to justify the postage

Vertigo · « **Reply #78 on:** July 25, 2011, 06:46:24 AM »

haha, yeah
