Interesting build. I noticed the first step was build pipe flanges, which are available in the plumbing section of your local hardware store. The next step could be done by using pipe clamps rather than drilling threaded rod. I like the seat adjustment mechanism. Thanks for the video.
dunno if you guys cares but if you are stoned like me during the covid times then you can stream pretty much all the new series on InstaFlixxer. Been binge watching with my brother during the lockdown =)
