In other words I have no clue what these are and would like to know .  These were things I found in my father in laws shop after he passed away, stuff that was tucked away in tool chests. At one time he had worked as a mill wright, but his last job before retiring was working in assembly for Gulfstream Areospace building executive jets, which would probably explain the 100 or so 6" long drill bits of the same size !! 

This one ain't a mystery but it's just cool to have a cresent wrench that reach around a corner !!

The drill with the spring is used in sheet metal work, the spring is a depth stop. The springs on mine are very stiff.

The other ones are rotary mills.

Thanks Mike, I kind of figured the drill bit had something to do with that since he had assembled aircraft. Yes the spring is really stiff, there are several of these, and probably 50 or so of the others in various sizes, some still have the protective coating on them.

The first one looks like a wire twister, but don't quote me on this. To me it looks like it was chucked into a drill or lathe and used to twist wires together by looping the wires through the two ears and then running the wires back to a fixed point.

I do something similar all the time on my farm to make high strength cables to hold my fences together; more specifically, the diagonal wire braces on my corner posts. Being in the areospace industry, I could see where your Dad might have needed to twist wire/electrical cables together a lot and made his own tool for doing so.

Just a guess though.

the first one I believe is for  metal parts in alignment so the next piece could be milled as it fit and locked the piece to the mill table so it didn't move or kept it in alignment..

 

The second picture first 2 bits are end mills for machining steel, the third is a piloted counterbore.

 

The 4th picture is a drill bit with a spring loaded depth limiter on it.

 

The Wrench pictured is an adjustable wrench but these were used on Hydraulic lines and other fittings.  The faa will not allow you to have an adjustable wrench or a pair of vise grips in your tool box to work on a airplane these days.

Actualy the FAA allows adjustable wrenches for some dumb reason, I don't know why but when I see my mechanics with them I make them take them home.
