I have drawn my lines for my layout (5x12 table) (I'm using 24 Radius/but I guess I could use larger)...My question is how do I keep the flex track centered between the line I've drawn on my paper? Understanding that the line is the center line (Yes, I'm using the foam for a base it is Pink) I can see how it could get way off if there's not some technique you follow. I have read where you can make your own Trammel using a yard stick...I've also read where you drill the hole at the 2" mark and the 1" mark to place your nail/screw in...Then measure from either the 1" or 2" mark...1.) The question is, Is there a difference? 2.) With a 5x12 table what is the widest radius I can use with flextrack? and what should be my center point using the yard stick? 2a.) Given the largest radius I can use, can someone give me a step by step explaination on this offset/easement topic. I've read many posts concerning, however, there seems to be varying opinions. 3.) What is the best distance to use between double track. I have heard 2" and 3"?
