Okay, thanks for that, looks like I've got some head scratching to do before I decide what to do :D

It was to be a built up wing, not solid, I had intended for the spars to be a 1" aluminium tube up front and 1/2" tube at the rear, which should be overkill really. I did think about a foam core and skinning it originally, but I have no tools for cutting the foam accurately, and I don't have vac-bag or anything available, anything with fibreglass, etc, would have to a wet layup. Basically, an angle grinder and a file is about all the tools available, we're a pretty fast car/team, but we operate on an absolute shoe-string of a budget, most guys we compete with have more money in their engines or shock absorbers than we have for an entire car + spares :D  Whilst it'd be cheaper to cut the wing ribs myself I thought a laser cut set might be cheap enough to be viable and take the most tedious part out.

Thanks dylan, I'll PM you later. Stefan - I had originally thought about doing it in a foam core and then fibreglass skin it, but - as most of you have probably guessed - this is for the rear of a rally car (well, actually, a safari buggy), and I was worried about flying rocks and tree branches snapping the trailing edge off if they get caught, hence deciding to go with ribbed construction and then profile an ally strip for the vulnerable sections.

I've just got a .pdf line drawing at the moment, and a point/co-ordinate plot of the respective profiles, but I can probably make it up in whatever is easiest for you, they're only slightly tweaked S1223 foils. Edited By Phillip Moffatt on 29/04/2014 21:52:55

Thanks guys, any thoughts on the trailing edges? I'm planning on shaping them from some aluminium strip to give some strength on the wing but obviously it'd be easier to match if they were on the ribs too.

Actually, while I'm asking, would it be worth me knocking the trailing edges off the parts I send for cutting and adding them later, I'm just wondering if this kind of thin taper would give a big problem for laser cutting/etc.   Edited By Pete B - Moderator on 29/04/2014 20:06:38

Hi all, sorry about my first post being a request for some cheap labour :D Anyway, I'm making a two-element foil approx 1.5m in length, and I'm wondering if anyone on here offers laser cutting/routing of custom spars from plywood or similar to save me trying to hand cut them all, or if anyone can point me to someone who does small jobs like this?
