First, the bike is stripped down to the basic frame.
Then it's time to cut the frame in half.
A precision blade guide is used to perfectly align the blade square to each
frame tube.
It also precisely spaces the cuts to remove the exact length of tube required to
make room for the coupling.
(Not the KHS frame but the process is the same for all bikes)
This photo shows the 1 3/8" gap left after removing a section of tube
that will be replaced by a coupling.
Two saw cuts are required per tube/coupling for a total of 4 cuts per bike (two
couplings).
Then, the paint is removed from the frame so the couplings can be silver
brazed in place.
Silver brazing the couplings into the frame (the white heat shield minimizes the
damage to the paint)
Once the couplings are silver brazed into the frame, the frame is
cleaned, repainted or touched up like this one then assembled
Packed in an S and S backpack case and ready to go!
You hacked my KHS soft-tail and it works great!
