Two Questions on Flex Track

1) What is the tightest radius that one can reasonably expect using flex?  I am building a traction/trolley layout and curves are very tight: R=10"-12 "

2) I have read where some users disassemble the rail from the ties and use a rail bender to aid in making curves.  What is the opinion on this?

Thanks in advance

No problem, terminology is important.   

Thanks for the tip on the program.  I tried another that wasn't as user friendly, but Thi one worked well.  First pass showed me that I have most of the track I need, except for the crossover.

I would like to put together a small layout for Christmas this year using EZ Track. Something a little more than a single loop, but simple and continuous running  The closest plan that I could find was one made for Atlas track that used a single 19 deg. crossover to "fold" an oval into a double loop.  I can't find anything similar in EZ track, so am looking for a pointer or two.


Thanks in advance
