Yes please.

Here you go. I fixed the labeling issue.

And here's the stl file for the box lid.

I had to compress it because it's a 2.4M file. The limit set for stl files was 2M so I changed it to 3M but it still wouldn't allow it to be attached.

I bought a Harbor Freight magnetic indicator stand last night. For less than 12 bucks, I'm satisfied. Magnet turns on and off smoothly, ground surfaces are flat and even, and it holds an indicator.

I probably won't use it much, but I had to know what the runout on my lathe is before machining the 5C adapter plate, so why not get one. I was pleasantly surprised to find it was under .0003" on the spindle, and the rough adapter plate was still within .0006". I believe the discrepancy is mostly in the roughness of the surface.

When checking the squareness of stock I had milled on the mill I kept getting out of squareness using the squares I had. I had bought them years ago for woodworking, long before I got involved in metalworking. It finally dawned on me that maybe the stock is square and the squares are not. Sure enough testing them against a 1-2-3 block proved that they were not very accurate. More than good enough for woodworking but not so for metalworking. So I bought this set which arrived yesterday.

I finally found a spacer block set that was reasonably priced. I use to have one and used it all of the time. Perfect for when gauge blocks are overkill, which for me is 99.5% of the time. They sure have gone up in price since I bought the last set.

After looking these up online, I have only one thing to say:

Yea, they aren't cheap. I think I paid $35 for the first set I had. This one costs $57.21.

I cheaped out and bought a set made for woodworking. Only has 1/16" to 2", by 1/16ths up to 1". Parts are red anodized aluminum, but it should work for me.

A tale of two dial calipers.

First to show up was this hot mess (at least it was cheap):

Which was promptly disassembled and cleaned up.  It was crunchy before, and afterwards was nice and smooth.  The thing actually changed color when I cleaned it.  However, at final assembly, I slipped and broke the stem where the pointer needle attaches.  Crap. 

Then a few days later, this showed up.  What a difference.  Mostly clean and unblemished other than the name engraved on the back.  Obviously well cared for, and smooth as can be.  My cheap chinese made Starrett is no match for this one.

   

   

Surprisingly, the price was also good.  I'm a happy camper.

Edit:  I will post a thread of pictures of my attempt to fix the Mitutoyo later on.  It will surely test the limits of precision I can achieve.
