You may have read my recent introduction to railclamps, delayed because I am using mostly code 250 rail, and I only just found out about code 250 railclamps. My main reason for clamping was to sort out bad rail joints in my flexitrack, by bad I mean from the point of view of alignment. I did a particularly poor section only yesterday, and have only just test run a loco on that section. Another problem I have been having is voltage drop, and to sort this out I was going to try to insert self tapping screws on the joint, which was going to be a very long job. I do not solder wires across the fishplates. To my surprise this newly clamped section runs not only smoothly but also shows no sign of any voltage drop. I have noticed that removed rail joiners manage to get a lot of fine muck trapped inside, I am hoping that the clamp will not suffer the same. Whether I will replace all my fishplates, rail joiners, or not remains to be seen, but I am a clamp convert from now on
