I've had my father-in-laws machinist tool box for about ten years. For about as long as I've had my Southbend 9A. My interests have evolved over that period - initially I used to the lathe for the production of mechanical wooden boxes - machining wood.
I've figured out most of the stuff in his kit - now that I'm getting a lot more into milling metal, there is more of it that will be useful.
So here are a few things I can figure out or that are puzzling in other ways. Hope to tap into the wealth of knowledge in this community.
First off, a set of clamps:
Not much of a puzzle what they are - however what's weird is the jacks thread in 3 - 4 full revolutions and then bind up quite tightly. So tight that you can't run them thru by hand. I haven't forced them. They clean enough that they should run through. It's possible that they don't go with the jaws but that doesn't make much sense to me. Why so tight?
Second question - what does one use clamps like this for when machining?
Second item:
What is it and how do you use it?
The ball ends and adjust-ability suggest that you can take and/or transfer measurements with it.
There is a square flat bit on the (bottom) end for marking?
Third item:
Again, I'm just guessing - the two shafts can be screwed in two orientations. Could be used (again) for taking inside readings of openings, setting mill cutter height etc.
Whatever - it's not obvious to me.
Forth item:
Parallels - with an odd profile?
They are about 6" long.
And finally:
I know that these are used on a surface plate or at least a flat table to measure or check height - but how and what are the typically used for?
Hope this is the right place for this sort of post.
