Welcome to the wood pile, Vic. You mentioned that you have a learning disability. In my opinion, those who think they know it all, or those that don't want to try, have the greatest learning disablities, so you are a step ahead of many I have met. Woodworkers commonly use a variety of terms and acronyms that may not make sense to non-woodworkers, so please feel free to ask if something is confusing to you. There is no such thing as a dumb question if you don't know the answer. I hope you get a lot of happiness and satisfaction from joining this forum.
