Very helpful, as is usual. Thank you.
Your animation is fantastic ! I've thought about how to straighten out 'hardened' wire . . . and the ONLY WAY that seems reasonable , is to stretch it very tight , while heating it to remove hardness . Once it is annealed , it would require heating again , to a hardening temperature , ( which I think could only be done with fairly short sections . . . ) * then comes the TRICK : how to quench the piece without distortion ? ? ?
No doubt , there must be a reasonable method to make it VERY STRAIGHT ! * * Maybe pull the wire through a 'drawing plate' while in the annealed state would work ? STILL , there is the problem of making the wire HARD again ! ! ! I'll go back to scratching my head ! ! !
Good video. Kent Vanderploed has a TH-cam video of twisting with a variable speed, reversing drill that seems to have more control. About 15 turns per foot for .031 (inch) wire. I enjoy your videos and look forward to them.
Watching this opening animation.... 🤣
Heating wikk remove the heat treating and associated stiffness. I would use the hole in the block method, which is:
drill she smallest hole the wire can fit through when straight in a scrap of 25mm stock. Clamp this in a vise. Start the wire through the hole, and use a pair of linesmens pliers as close to the block as possible, while leaving a small space between the pliers and the block. This gives the shortest radius of action, and consequently concentrates the applied stress on this small part of the wire. Bend the wire, then advance it into the hole and repeat. On and on until the entire wire is through the hole. You;ll see what I mean. An old engineering axiom is: "you must bend something to straighten it" Never more true than here. This is essentially a manual versioin of the straightening mechanism at the entrance of a machine like a nail maker when working with coil stock. Hope this helps, I suspect it will.
