Gage Block Buildup Calculator

So, I have that Python source code on the side of my site there for calculating gage block buildups. I figured it was time to turn it into a JS program so that people can just access it from the web. Not super complicated but useful nonetheless.

Features as follows:

  • Imperial 81, 28, 34, 36 and 92 pc sets
  • Metric 88, 47 and 112 pc sets
  • Multiple ( as many as you want) results
  • The ability to remove blocks from the list if they are either missing or used in a previous buildup. This is handy.

Anyways, hope somebody out there enjoys this!

An RTJ chart

Here is a chart for RTJ ring groove facings. It’s very specific to my own use case but maybe somebody else will find it useful. I guarantee nothing, if you use it, it’s at your own risk. Bottom width is the size at the bottom of the groove, Largest Ball is the largest ball that will sit tangent at the top of the groove, and well, Smallest is the one that will sit on the bottom and touch the two sides. Obviously you want to be somewhere between, not at, theses sizes. Also, the lists on the bottom denote the Depth, Width sets and the numbers that follow are the R sizes that match that set.

CMM, a test video

So, I was measuring a plate on our Mitutoyo CMM yesterday and I figured it’d be a good test to see how videos embed on WordPress these days. When I started this site the first time, you could not embed videos very easily and you had to embed with either YouTube or whatever other video service was available. Still, the limit is only 512MB but, hey, good enough. That’s almost enough for a movie.

This was a plate we needed to grind flat withing a few thou. Worked out well.

A new die/punch housing

Just finished a new die/punch housing for use on an old press. Works well and allows you to index at different distances. The initial drawing was kind of wrong when I drew it but I just shifted it a bit to work given the machine.
