Locost Airbox?

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

And who never would be missed-- who never would be missed!

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 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

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!

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.
