Challenge: Learn how to join and connect various pieces of Delrin. Connect two pieces of sheet Delrin using heat-staking, piano wire, and notches/pegs. Also explore the implications of loose fits vs. tight fits and bushings on Delrin rod. You will rotate through stations in the classroom/lab to learn each part of the process.
Today, during class, we had four mini "workshops" where we learned different skills.
1) I had to connect two pieces of Delrin using heat-staking. My pieces moved around a little because there was a small gap between the two pieces (I should have pressed it down more).
2) My next task was to connect two pieces of Delrin by drilling a hole and putting a piano wire through the hole. I could have centered the hole better. Also, the piano wire was bent, so I could not push it through all the way.
3) The third activity was to play around with different bushings and Delrin rods to develop a sense of what would be a loose fit versus what would be a tight fit.
4) We are not finished with sketching the 5 cm x 5 cm square (with different-sized openings) on Solidworks, but this activity is to show how 0.02 cm could make a difference (loose fit vs. tight fit). *Update: Our laser cutter had some problems, so we had to see our classmate Ashley's notches and pegs to gain a better idea of what was a good fit/tight fit/loose fit.
I made some mistakes, but they helped me gain a better understanding of how I should fasten/attach pieces of sheet Delrin. I am excited about using these new skills to design and to build my next project, a well windlass.
