Anybody have any idea why I can't find aluminum tubing to replace my TheMightyHobie18 tiller crossbar? I'm not the best mathematician, so I've got some weird measurements off the conversions from mm to inches (my micrometer is Russian), but even then I can't find tubing/pipe that is remotely near the measurements in OD, ID and wall thicknesses ... anybody have any suggestions/ideas? I tried one on-line place someone of the F18 forum gave me and that didn't work ...

thanks
