SUPERCEDED by http://www.thingiverse.com/thing:8275/* The Printable Clock Project by Syvwlch, with help from MakerBlock, rustedrobot, barrychuck, and many others at Thingiverse. Test Jig - Minutes and Seconds Only http://www.thingiverse.com/thing:8128A minutes & seconds only test jig for the printable clock project.This configuration, with only one gear between them, should have little enough friction to drive the escapement wheel from the drum. The frame sytem has also been improved to include the escapement shaft. Hopefully, this test jig should allow us to actually test the escapement for the first time!CC-A-SA licensed.*/I also went ahead and enlarged the diameter for the shafts to 3mm and made the sleeves thinner to compensate. It seemed ok to do so, since rustedrobot mods his parts with a drill to get the same result. ;-)This script relies on both the MCAD involute_gear library and on my own clockwork library.Current repository for the latest version of the clockwork library: http://www.thingiverse.com/thing:8155Print one of each STL file, or fiddle with the script, check your work with assembled(), and then generate a new STL for each part with laidOutToPrint(), and print those.This test jig requires three shafts to slip the sleeved gears over, outer diameter 3mm with a clearance of half a millimeter either side, so M3 will work... without drilling!In order to accommodate the frame, I had to make the escapement wheel a tad smaller, which also resized the escapement, so those parts are not interchangeable with previous clock versions, sorry.Test #1: with the escapement (04) in place, are there any escapement positions for which the escapement wheel (03) can rotate freely?If yes, test failed.Test #2: without the escapement in place, can the escapement wheel be made to turn by applying moderate torque to the drum (01)? How much flex is there in the frame during this test?If no, test failed.Test #3: with the escapement in place, and with moderate clockwise torque applied to the drum, does swinging the escapement slowly back and forth cause the escapement wheel to 'tick' forward by one tooth for every swing?If no, test failed.Test #4: repeat test #3, but instead of swinging the escapement back and forth, slowly push the escapement until the escapement wheel 'ticks'. When it does, does the escapement jump ahead a little, indicating that the wheel gave it an 'impulse'?If no, test failed.
