Hi,
Now, 21:30 at Japan.
Step4:
Step4 is the making of very important parts. In case of non-suitable Disk brake frame, the dropout and the joint of dropout & frame-pipe are not strong. The joint of dropout & frame-pipe must be reinforced. I made short pipe from rod of A6061-T6 by lathe. This step was most difficult working.
If this reinforcement pipe doesn’t exist, the crack will be caused on the welding part of joint of dropend and frame-pipe by innumerable braking.
