How far is too far Mike? : ) I just used 4# of wire filling in holes in one of my 5U frames so I can actually bolt the rollers on instead of welding them. Fitted new idler ears to the front of the frame as the originals were all worn out (like paper thin at the ends) and the previous owner had glued a piece of 1" to the side to help. I'm still debating whether to fit the D3 rollers to these frames or put D2 ones on this and build and brand new set of frames.

Wow, Mike, you’re certainly not afraid of a project! I shall follow with interest as usual..

Regards,

Tony
