And here i thought you had taken it apart just for me! Thanks for that though! It helps a lot. my smaller idlers are 12.70 mm and my front idler is 34.50mm. my fronr idler will be bigger for sure but my smaller ones will be larger than yours all because i think so far i am going to use roller chain and tig small nuts to the outside to mount the tracks to. but i will run aluminum bar threw a table saw ti get the track cleats much like yours.
