I've been reading a few of the threads, and I've noticed that the ideal size for the pack is around 16" wide. My question is, using the fantastic plans from Alan (JetPack SS15). Is it a matter of scaling it up by another half inch? Making the "one inch" scale "one and a half inches"? or I'm currently redrawing these plans for cutting in a laser and at the current scale. It suits the PVC pipe i can get a hold of. Don't want to have to redo it all at a later stage.
Sorry if this has been answered before. I couldn't seem to find anything tho!??!
Cheers in advance
