On these pages I will highlight a few of the projects I have completed as samples of the quality of work that a customer
should expect. Please check in often because I will frequently update these pages with new items.

So what, you say? A spring? A bird? A plane? Able to leap tall buildings in a single bound?
No, none of the above. This is a filament made of .020 inch diameter tungsten wire. For the eagle eyes among you, yes
each coil gets slightly larger as you look to the right. This taper had to fit a type of ceramic crucible used to vaporize
different materials inside of a UHV chamber. Plus the filament had to have rather sharp bends to insert in the electrodes
that it hooked up to. As if this wasn't enough, it still had to fit accurately into a very small space
so that a manipulating arm could change the crucibles just by lifting them up. For those who have tried to bend tungsten,
you will understand the challenges faced with this one. Oh, by the way, while you are at it, make six alike for replacements!

Here I have a glass disk that is 2 1/4 inch in diameter and 1/4 inch thick. I was making it to duplicate an antique clock
pendulum for a clock I was restoring many years ago. I spent 8 hours grinding and polishing the bevel all the way around and
then engraved/etched the trademark on the back. While doing the final polishing to remove a really tiny flaw, it slipped from
my grip and hit the concrete floor. You can see the result. I had to start all over again and I made another just like this
one, but didn't slip this time.
After I took this picture for this webite, I was holding this item up to see if I could find a different way to
have the light come through and better show its brilliance. Guess what, it slipped from my grip again. This reminded
me of what I used to tell people years ago when my wife and I sold antiques. I claimed I had developed a foolproof method
for determining if a glass item was antique and therefore valuable. Just let me hold it, if it is valuable I'll break it without
trying. It seems to work for me.
Yes, I thought it ironic that this is my "Bits and Pieces" page.
