Locost Airbox?
RazMan - 16/12/10 at 02:59 PM

Has anybody figured out a Locost version of the Piper PX600 airbox?



A remarkably simple design ... but a very complicated price
There must be a cheaper way eh guys?

Well it shouldn't be seeing any significant vacuum, (as you are using ITBs) so why not have a look around until you find some ready made plastic box etc that will fit the space available. Alternatively I suppose making something bespoke in GRPor ally is the way to go

I may have a spare similar arrangement kicking about somewhere, if i get chance i'll have a look if interested

I've thought about this type of thing and I'm sure, with mine being a V twin, I could use a modified butty box.

Same thought occurred to me - I'm sure there must be some suitably sized tupperware items

You have my undivided attention Mr B

You must have huge butties for your lunch, or maybe you have a 400mm long Sub Roll!

How about some form of trunking? - it would need to be (in my case) about 450mm long, 100mm wide & 50mm deep.
.... and I need 2 of 'em.

*edit* Found this but it's plastic and I doubt it would stand the heat NEW trunking cable wire tidy 50mm x 100mm 1M length on eBay (end time 28-Dec-10 14:00:43 GMT)

If I can make a buck, I could mould it with fibreglass

Trunking that size ......... sounds a bit like guttering to me.

do a search. Steve H has a vid here somewhere showing what he's done in CF. He makes it look simple, which we know is not exactly the case!

I spent several days making a buck to mould something similar, realised the shape I'd made couldn't release unless I made the mould in about five parts, and gave in and knocked one up in ally in about 3 hours

I'd still like to re-visit moulding one eventually, but it's not likely to happen any time soon.

I found a really good video about making a mould - certainly LOOKS easy enough

Some of the guttering profiles look good - I am thinking the 115mm half round cast ally might be useful. They even have end caps which simplifies things a bit but the trouble is there's going to be quite a bit of welding to graft on the intakes. It's a pity I can't use a TIG

You've obviously never met him if you think that's a bad state of fingernails, that's the cleanest he's Ever been!

Could have had a shave and tidy workspace too!!

If you need to mould a fully enclosed box (like an airbox) making a conventional buck would be impossible as you wouldn't be able to remove it. I was thinking about the possiblity of using candle wax as a buck, encasing the whole thing in fibreglass, then cutting the required holes and finally heating it up with a hot air gun to melt the wax - voila!

How about polystyrene too, wouldnt be as nice inside, but same idea. Acetone would dissolve it nicely!


RazMan - 17/12/10 at 11:47 AM

Aha! If you use polystyrene foam and wrap it in parcel tape, it will have smooth finish on the inside. 2 layers of heavy glass mat should do the job - a good hi-build primer will give a reasonable finish on the outside.
