I have 8 built and I think 9 to build.
I have been collecting parts etc but a few months back noticed that I hadn't acquired enough headsets and stems so had to focus for a while on getting more. I have quite a few wheels that either need building up, stripping re anno and then rebuilding, but it just finding the time. My lad has just started rugby training and I have got roped into becoming a trainer as there are so many kids attending they needed more dads, so that is Sunday mornings written off, footy practice for the lad Sat morning plus then add the missus chores etc doesn't leave much garage time
