Now that I've covered safety. Fantastic video, which I hope I can use in my lessons of machining and design techniques to fascinate my students even more for our profession and to develop and shape our and their skills into first-class mechanics ❣️
We use the machine jacks to support the workpiece, not the toe clamp. If you were to set the positive angle you would push/clamp on one point of its diameter (tangential). This pushes the Jack away. or only to be used with 100% 0 degree alignment… even then use little cutting speed and material removal. Keep it safe❣️
A method useful with tiny delicate pieces is to hold or support them in a small tray of low melting point metal (Cerrobend) and remove later with boiling water or hot air gun. (I use a block of aluminum that has a pocket about the size of a matchbox.) Have also read of parts being frozen inside blocks of ice for machining!
Toe-clamp must be used between 0 and positive 5 degree angle. I set it level en go one step up. The bolt is as close to the workpiece as possible and not the clamping blocks, you want to clamp the part not the blocks.
