Double check seat tube fit at the bottom bracket
shells.
Produce 2 doughnuts to fit the 1 1/4" head tube.
|
Produce another arm to support the front triangle and thread it to hold the head tube stand off's.
|
Head tube stand off's mounted.
|
The arm support. This mounts to the jig to hold the main arm.
|
The main arm support mounting plate. Ready to weld.
|
The welded plate ready to drill and slot.
|
The main jig drilled and threaded for the plate.
|
The plate mounted. Note the two holes on the front of the plate. The main arm mount will bolt here.
|
The front triangle mounted and level
|
The main frame is ready to tack and weld.
|
Next week we will check the alignment of all the tubes. Be sure they are all straight and center. I will then tack the frame (putting a small weld bead on each tube joint to hold it as a single unit) check the alignment again then weld it. Once it is welded we will check the alignment again and do any final "tweeking" if necessary.
