Hi Martin, thanks for the build info. I would still be sat staring at the plans without it. My method of keeping the jig true and steady is to glue it to a piece of worktop. This frees up my building board for the fuselage (a bit of multi-tasking coming up). I've started early because I'm an old Duffer who takes his time. I've shaped the wing skins and marked them up. Time to start gluing.
I tried to add a photo but failed..... so much to learn...
