This last week was BUSY!
We did get to spend a bit of time on the Sporty chop.
Here are a few pics of the 1st Gen Jockey shift we made with the 3D printer.
Shift arm added-
We did not like how the pivot arm was so far forward up top. So we made a different pivot arm that is more upright on top.
Another view-
After much looking & playing with it, we decided we did not like it at all.
We made the following decisions:
1. The S-shaped shifter arm is cool (to us), but it sticks out too far. It is being redesigned with 1 less curve in it.
2. The main bracket (XXXX) is too big and ugly. A smaller one is being designed and will mount up at A & B points shown in the photo below.
3. The whole concept of a pivot arm (Y) & accompanying shift lever plate was interesting, and different, but in the end it was too busy, & has leverage challenges. So we are starting fresh, and we'll have a simpler design printed out soon.
After putting that to bed, we spent a couple of hours looking for fresh ideas on a foot clutch. We came up with a few different drawings (can't find the photo's I took of them), but we still have not settled on one.
We even spent about 45 minutes studying how the cams on a compound bow works, seeing if we want to use something similar in the foot clutch design.
We did come up with one steampunk style design that is pretty cool, but I don't want to use it on this particular bike where I am trying to keep everything as clean/simple looking as possible.
Any ideas, photo's or drawings are appreciated.
