RE: Covering
Hi,
I would suggest the best way to learn is to join a local club and get to know some of the more competent builders. Nearly everone is keen to help when approached in an appropriate manner.
If this isn't an option I would suggest that you get a trainer kit. I would suggest this anyway. Building the trainer kit will get you into the mindset for building the CUB and allow you fairly painless experimenting with covering.
Good Luck,
Colin
