I think you are doing a fine job on your first build. Doing anything in life is a learning prosess with mistakes along the way. But it sounds like you are starting to get a better feal for what you are doing. You have been able to fix ,and overcome the mistakes you have made whitch is great. it means you are on the road to becoming a better guitar builder/woodworker. Most of what you are doing is woodworking skills, and as you learn what works and what doesn't you gain in your skills. The PG forum is a great place to pick some brains on all types of subjects, but keep in mind what will work for some people might not work for you in your givin situation. I have been building things since I was 5 years old, and learned at an early age that I loved to work with wood.
I remember a time when I was working in a cabinet shop on this custom solid oak desk. I had the top all done with cardboard over top of it so it wouldn't get scratched up. Well in my brilliance I decided to drill the holes for the drawer pull on the drawer fronts before attaching them to the drawers. Needles to say the bit went through the drawer front, and then the cardboard, and then into the oak top. major mistake when i removed the cardboard there were three holes in the top. Itold my boss what I did and he told me to fix it. So i filled the holes with a combination of wood glue and wood that matched the grain patern best. Then used an exato knife to make a little more grain detail and you couldn't see it at all once it was stained and finished.
So don't be to discouraged on your mistakes they are making you a better builder. and in the future you won't make them again. Some of the best jig material I use is baltic birtch. It is very strong and can take a good drop off the work bench without breaking like plexi would.
I can't wait to see your ccompleted guitar it will represent alot more than just a musical instument. It will represent the jouney you took in ceating it...
Build on ihocky2
Good luck
