Thanks Very Much!

The problem of finding edges of non-conductive materials....

Here's one made from a scrap of drill rod and a skate bearing.
It'll locate edges EX-tremely well and is easy to use....

Just find one edge. Zero the DRO... Find opposite edge and set
the DRO axis to half. Move to dead center and drill....

This isn't my own idea, but I wasn't able to find very many examples
of someone actually making one and trying it.
I've been right at the doorstep of buying a $$$$ one for some time,
but few of them work with materials other than metals.

It was pretty easy to make on the lathe. It's only off by a very
tiny bit, but that works to my advantage of being able to see the
mark on the bearing 'skipping' easily.

I'll have to try that one , it would be a good method to use with the high speed router , regular edge finders and high rpm's don't go well together

I'm running it somewhat low....maybe 350 rpm.

I might be concerned about the grease slinging out at too
high of a speed. I know even Oilites will sling the oil out if I
run them too fast in the lathe....(sometimes they're customized
a tiny bit)

But there's got to be a way....

I wouldn't worry much about the grease leaking but
now that I've thought about it low rpm bearings at high rpms is purely dangerous , sort of like playing with a grenade
I'll stick with the homemade probe

Speaking of playing with a grenade...

I run the reamers at a low speed and it's so slow and so many flutes
that it's easy to brush a few flakes off with a finger without it seeming
like a dumb thing to do. But it grabbed my finger the other day and
if I hadn't had *just enough* clearance in the vise....I'd be much
more sorry than I've been in a long while.

I Always keep a long bamboo skewer close to the lathe and mill for
when it gets tempting to knock a little trash out of the way.

I won't touch another thing spinning in a mill again. It sure looked
safe enough. It always had been. Not anymore!

it only takes that one time that things don't go right , and some things are better not learned the hard way , I've got a bad habit of not using my vise on my drill press and I'll hold the part tightly in my hand , I've been shredded a few times by spinning parts , but like the lab rat to the electrified chunk of cheese I'll bite again .
the key is to always have crazy glue close by for the larger gashes

I use crazy glue too. It mystifies a lot of people, but it works Great, and
I'm back in business within minutes...

Stuck my hand under a spinning 4" sawblade once..... Slash!
