While I was working on generating the cover/tape guide, I was printing out the cover tape feed sprocket.
Getting just the right tension was proving challenging, so I changed the design.
The addition of the slots should allow those areas to bend out slightly. The mating slant from the upper portion now means that downward pressure will increase the tension.
This should now allow me to tune the friction. Now I can put a thumb screw or the like in the center on the bearing, and ultimately control the applied tape tension that way.
There is one caveat in that the feed sprocket for the cover tape will now slide against the body to maintain that tension, so I will have to make sure that source of friction is less than that which the bearing surface is presenting. I think adding a few raised areas on the body will suffice.
Back to work..
