So, if you want to make a large polariscope, find a LCD monitor, get
the filters out and glue them on a piece of glass.
I googled this about polariscopes:

clear.

Hello all you bicyclers,
I thougt this EMC was a machine controlling forum, but machining machines,
not riding machines. Let's confine ourselves to machine control and
exchange construction hints (how thick should the stock be?) and
motorbiking experiences at other news congregations.

The important part about the P number is if you use it it turns on the naive

Can you spell product liability insurance? I consider that to be an

Finite element analysis, fatigue testing, and destructive testing might

I finally produced my first part on my new Kasuga/Emc2 (Mesa 5i20/7i33) knee

moves tend to slow the feedrates down a bit,

Not true - tool lengths can be positive or negative. I set up the

longest and everything else shorter (negative offset).

ok, you move the knee

something we used to do on the quill may be of help
we'd slit a piece of conduit
grind it to length

rides in
this gives you a fast mechanical offset
something like this slotted tube may work
