Jeff,
I once had a Quickie ( Q1 ) that broke a tailspring. ( don't they
all ). Anyhew, I replace it with one designed for a Dragonfly and
never had a problem with it after that. The Dragonfly spring was a
different material of construction and shape than the Quickie's. I
don't remember where I ordered the Dragonfly spring, but I would like
to get another one for another project. Do you know who sells them
nowadays? Thanks

Neal
