Frame / Forks

Kayla, Gillian, Erin

What we have accomplished so far as of 3/15/22

  • We took apart the frame and fork assembly.
  • We degreased lots of parts of the frame
  • We sandblasted the main frame part and some additional parts

On 3/16/22: We primed the main frame outside

On 3/21/22: We cleaned out the battery box using both a parts cleaner and a degreaser, sanded the main frame using 300 grit sandpaper, and did a second coat of primer on the main frame.

On 3/23/22: We painted the main frame red outside (one and a half coats). Pictured below!

On 4/04/22: We continued sanding and sandblasting the fork tubes. Once we were finished, we primed the fork tubes (pictured below).

On 4/06/22: We used the hand machine that sands objects to sand down triple tree, which holds the fork tubes in place. They we primed that part and a few other parts. We also painted the fork tubes themselves.

On 4/11/22: We cleaned the fork springs and some other parts

On 4/13/22: We started to put together the fork assembly. We greased the balls bearing and put it together then sanded down the inner fork tubes so they would fit inside the triple tree. Unfortunately, we had to take apart the fork tubes because we forgot to add something, but that is all part of the process!

On 4/18/22: We finished putting together the front fork tubes and cleaned, sanded and primed a few other parts.

On 4/20/22:  We finished putting together the triple tree assembly

On 4/25/22: We cleaned all the springs for the back fork assembly and sanded and degreased the parts that go with the back forks

On 4/27/22: We cleaned and put together the brake cable and helped to adjust other parts that are associated with it.

Final Poster Presentation: Frame and Forks group presentation – Erin, Kayla, Gillian-2

Special things we have learned:

  • How to make your own nut and use a tap and a die to fix and recut threads
  • How to use the bronze bush. (front forks slide on each other). The back forks slide on it too. What keeps it centered is two springs
