    To make a brake bridge, a similar process is followed with its own mold,

    So, we have all the pieces of the puzzle now. It's time to put them all together in an actual frame. That will be in my next installment.

    Hello everyone. I shall continue with my story. With all the tubing made and the bike design finalized (length of each tube, angles, etc.), they are cut to the exact size using a lathe (as pictured) or by hand.

    Now comes the trickiest part : to place all tubes in the frame fixture. The end result in terms of proper frame alignment and balance will depend on this step ,

    Once the proper placement and alignment of all the tubes has been achieved on the frame fixture (and I cannot stress enough how important this step is), they are glued together with an adhesive to keep the whole frame as a unit when removed from the fixture. The next step is to make an alignment check to make sure that all fits properly (see photo). This is a somewhat unnecessary step when working with carbon. Steel , titanium or even aluminum, can be "forced" to align after being welded by cold forging. On the other hand, carbon , once the tubes have been glued , you can not realign it, unless you unglue the tubes and start all over again (strongly not recommended ).
