thanks for answering my questions.
sorry that was rude of me to ask you what you had allready gone to the
time and trouble to put on your site. I had gotten wrapped up in the
welding and ran out of time while looking at the boat project. then
asked you here instead of going back.
BTW I went into the welding thinking lets see what this guy knows. lol
i left it sure that you know ALOT more than I on that subject
you put together a very nice site. I feel you did a wonderfull job
putting the physics in to lay terms that anyone can understand well
done
