considering making a top guide and I could use a little help
current plan is to use 1.5mm thick sheet aluminium for the back plate, and 1mm thick carbon sheet for the cage
couple of questions-
will the backplate be stiff enough, or should I get something thicker? most guides seem to use 3mm+ thick aluminium. there is quite a price jump going from 1.5mm to 2 or 3mm. the cage should be pretty lightweight.
can/should I use a laser cutter on the carbon?
how much can I expect laser cutting to cost?
thanks Smile

I got a piece of 3mm big enough for 4 back plates for 4 quid at a metal fabricators as a off cut. Try that maybe? Anything thinner is a bit flexy, my dad had some 2mm which i tried first and it just flexed because of the length of the arms

Do you just walk in and ask for offcuts?
It might actually be cheaper to just do the whole thing out of carbon if I'm buying online

What's more important is the type of aluminum.

Expect anything to cost a lot in aberdeen. Oil and gas industry has hiked up manufacturing costs. No one is going to be interested in helping some kid make some bike parts apart from some small machine shops. You'd be better off asking to use tools in uni.

Also no one really does carbon fibre in aberdeen apart from the university's for the formula student stuff, you'd be better asking mr magura for some homebrew ideas as hes the boy when it comes to CF

I've found this, which might be of interest to you if you've not heard about it already. I might have to check it out myself at some point in the near future. All I'd be doing with carbon is buying some rigid sheet online and cutting shapes from it, no moulding or anything complex.
currently speaking to iffy about laser cutting though, seems to be the way forward at this stage.

edit, iffys stuff is 6082 - T6~T651, sound good?
