The Bozo Thread Debacle
| I tell this against myself !! Feel free to laugh! A classic example of near total lack of observational skills! Objective - make a replacement sash clamp leadscrew - 12 TPI ACME determined and project begins... not until an advanced stage was the mistake spotted, when it should have been seen early on! We show the progress until the penny (finally) drops! :) There is no cam-lock on the lathe so to cut double produces a problem of accurate indexing for a second cut - yet to solve this fully. |
