We have been restoring a Tumblebug and reached an impasse. We
don’t know what mechanism is required to trip the load or how it
was installed. The wheels are new and were made by Ron Scofield in
Fiddletown, Calif., from hubs and rims that we salvaged along with
the rest of the parts in Bellevue, Idaho. Any help would be
appreciated.
