Re: [gingery_machines] new article: A Low Cost "Digital" Angle Gage

For those of us who suffer from "math anxiety" (US)) this is really a nice thing! I spend my time devising ways of doing things using geometry and construction, avoiding "maths"(UK). "Cos" and stuff literally makes me shut down mentally. I was extremely relieved when I found this!

I really like the idea of sine bars, a beautiful principal, just the "Maths" gives me a short circuit between the ears!

no need to reinvent the wheel by making it more complicated. far easier to buy than it is to make.

This article presents a simple variation on a sine bar that uses my digital
caliper to set the angle. Making this instrument is simple. Dealing with the
equation needed to set it to the right angle may be more than some can
tolerate even though the heavy lifting is all done in an Excel spreadsheet.

Questions and comments are always welcome. All of us are smarter than any
one of us.
