i added a second stem to my bike, but the hardest part of this project is finding the short section of tubing to insert into the second stem. i've called all the local LBSs and tried the hardware stores, but the LBSs either don't have the scrap pipe or don't cut pipe; and the hardware stores do have electrical conduit that looks like it would work, but can't cut it for me. anybody have any suggestions on what i can use?
