A Novice Mistake

<< < (2/2)

Alan Haisley:
I made one of these from a piece of hot rolled steel. Each hole is tapped for one of my commonly sized screws. The slit was made with a jeweler's hand saw but could be made with a slitting saw in the mill.
The original example of this tool had it case hardened after all the cutting but mine isn't hardened at all so eventually it will need to be remade.
In use, you screw the screw in as far as desired, clamp the plate edge on in a vise, and saw and file the screw to length.
I made mine so I wouldn't need to stock a bazillion lengths of each size screw.

Bezalel:

Alas! another briliant little bl*****y gismo I need to make   :cussing:

Part of that experience is called "planing ahead". It is about what machining steps to do at what time. And what might happen at each step. And having the experience what steps are a piece of cake, what steps are risky and what steps are sure to fail.
In buzzword-language it is called "risk-management". :)


Don't worry, every machinist has to make these mistakes by himself.

Alan, good idea, I made the separate nuts or coupling nuts if I could find them. Any oddball sizes I made from hex rod .Your idea is better,
mike

Alan Haisley:
I was able to find the original source of this idea. It came from Bob Shores and was posted on the Florida Association of Model Engineers website. Bob - and others - have several useful ideas posted there; worth checking out.
