What Did You Buy Today?

New to the site... 1st post.

Check out this set of calipers...

Leave it to the French to make it beautiful as well as functional.

Check out the tin that they are in. Not sure if that is original or not.

The measurement shown is about .788" (as measured real quick with my calipers)

The inch vernier increment appears to be 128th (.0078") of an inch.
.750 + (5 on the vernier) .039 = .789"

It's the first tool I've ever seen graduated in 128ths.
Thank God for decimals.

Bought

Also sold my old mill so I had an extra 1000lb of weight allowance for the move

I really like rusty crap... I guess...

I picked up an old, rusty Fairbanks platform scale today...



I've been keeping a lookout for one of these cheap for a while. I've found a few, but they have all been missing the weights or the weight hanger. This one has all the weights...



It looks rough, but works very well, except it doesn't read accurately... it reads about 29½ pounds heavy...



...from empty to my current weight as compared to our fancy digital bathroom scale.

The best I can figure, it is calibrated by adding or subtracting weight from a cup on the bottom of the weight hanger...



By my caculation, it will need around 5 oz added to that cup... but when I shake it, it sounds like the cup is almost full now...

There is another fine adjustment...



... a weight on a screw, but adjusting this only changes the reading about 2 pounds or so.

I'll see if I can figure it out somehow...

@682bear
If it reads heavy, I think you want to take weight out of the cup, not add it.

Edit: misunderstood

Won't look original (if that matters), but how about a 5oz. slotted disk on top of the weight hander disk? Might be hard finding a piece of steel that is rusty enough though.

It's just the opposite... if you set the slider at zero with no weight on the platform, you have to push down on the hanger to move the beam...

Or, moving the slider out to 29½ pounds causes the beam to lower to the balance point.

FWIW, I thought the same thing you did... and so did my wife... until we tinkered with it a bit...

That doesn't matter to me... I did think about adding a thin disk...

It would take a lot of trial and error to get it at just the right weight... but that is definately an idea.

Semantics disconnect here. Now I get it.

I suggest that, if it's that far off, to get it working properly you should check that everything is it should be (nor bound or bent). Maybe you just want yard art?
