Just out of ongoing curiosity, what type of material are those pieces that you've used to attach the casters to the rails? How did you fasten them together?
Thanks for your interest. I wish I could say it was carefully engineered from start to finish, but I used scraps of steel I had on hand. In this case, the scraps were some short pieces of 1/2" square tubing leftover from another project. I am thankful to have a welder. At the front of the roller frame I was able to weld square tubing alongside the piece of steel on each side that holds the rollers off of the floor. At the back wheel of the bike the casters needed to be located between the two rear rollers. There was already a hole in the roller's frame halfway between the two rear rollers. I welded the square pieces of tubing to a small piece of steel and drilled a hole in the piece of steel for a bolt to hold it to the frame. I used a second set of square tubing pieces to move the casters outward and not lose any useable riding area on the rollers. If this is not too clear, I could make some additional pictures.
Without a welder, this would have been a much more difficult modification. Still, it might have been possible with some careful drilling and use of small bolts.
