Has anyone created an offset table for the "L" version? I understand it is 6% larger and I can handle the transformation of the x,y data pairs but what about the length? Is the form spacing stretched to end up at 18"? Any and all assistance will be appreciated as I am a newbie but would like to start as soon as it cools off here in Phoenix. I would also like to be done glassing before it hits 110 next year.
