7-17-11 Finally started working on new Parlor. Most people have said making your own 24" diameter sprocket wasn't a good idea. It's not humanly possible. Only god can make a sprocket. So we did a test section and it wasn't perfect but it wasn't impossible. Matt Sponer and Peter Luca tirelessly worked to get us to the position shown in the video. The turntable took two people to lift onto the drill press. It was 8PM so we quit.

7-18-11 The next day, I finished the first sprocket and the first 20 drilled holes were way off as we forgot to tighten some bolts. I couldn't just re-drill because the bit wandered into the old holes. So I welded up the 20 holes and then re-drilled. These teeth would be weak but there are about 80 more engaged at any one time. But then the last hole was 1/8" off.
   The second plate was too small to make 150 holes anyway. So, great. How many man-hours did this lesson cost? It was about 2:30PM (time to go to the dentist. ((tooth-hurty - 144 tooth hurty)), and we started yesterday at noon. 37. Thirty seven man-hours so far. Doesn't matter. I redid the hole thing with 144 holes. This is 23" diameter. Practically the same thing. I only drilled the pilot holes as the Turret Drill Press has quit working some time ago. It developed Turrets Syndrome. That'l probably cost $20,000 or so. The 145th hole lined up perfectly with the 1st hole on both plates. The hole time I was on the verge of giving up on the hole thing. I still don't have a hole lot of faith, but now I have my teeth sunk into .... whatever. Tooth hurty.

   Our sprockets are getting married. They are engaged. Worst pun ever?
