New gears arrived for the 2501 card reader restoration

NEW HOPPER GEAR CAME OUT CORRECT FROM SAME STL FILE AS THE OTHER

The first gear I had printed using the craftcloud3d.com broker service did not have the correct high walls. This new print had the exact same STL file sent but it was done properly. The printing service that did a good job was Detroit 3D Manufacturing, someone I will select when I use the broker service again. 

By comparison, look at the old order made by 'elipac 3D' where the wall and the outside teeth end prematurely. 

NEW STACKER GEAR TO REPLACE THE ONE THAT SNAPPED

I had a hopper gear whose teeth bent inwards towards the center as the extended further up from the bracing at the bottom. To get this to fit on the aluminum disk which forms the gear I had to attempt to bend it slightly but it broke in half. The gear did match the STL file, but the result wasn't good. 

Friends suggested a change in material that would suffer less from the deformation and bending of the sides of the teeth, so when I reprinted I selected a different plastic. I also used 'Detroit 3D Manufacturing' and in this case also the part was excellent when I received it. 

Comparing it to the prior gear, the one I snapped, I believe this new one is to be superior on the merits of the printing quality. The picture below of the snapped older gear isn't very sharp, I am afraid.

RECOVERY FROM KNEE REPLACEMENT - BEATING EXPECTATIONS

On Monday 21 April I had my right knee replaced, was walking with the aid of a rolling walker that night. Before I was sent home on Tuesday morning I could already bend more than 105 degrees and almost fully straighten the knee. I never needed pain killers outside of Tylenol and had remarkably little pain. 

The Wednesday 23 April I was able to walk without the walker as a support. I could do marching steps backwards and forwards at the Physical Therapy facility on Thursday as well as stand on the repaired leg while tapping my good foot back and forth, all with good balance. 

The only consequences of the operation are the swelling of the leg and bruising, but as long as I continue all the exercises and ice it frequently, those will greatly reduce or disappear in a week. I am extremely optimistic about resuming my workshop activities - except for any that might require me to kneel on the new knee - within a week.
