Palmgren 30601 CV60 6-Inch Cross Vise Review

In spite of the quality of construction that went in to this vise the thread on the travel screw handles is not long enough to engage the locking insert of the nut for the traverse handles. This tension is important to the smooth operation of the slide. I was forced to use locktite to secure the nut at the right tension. Other than this shortfall it is a good piece of equipment

Grizzly G9765 Ball End Mill Set - 9 pc. Review

I couldn't believe my eyes when I opened this box and another box from Grizzly that had conventional End Mills in it.....Grizzly ships these products loose and they literally beat themselves up. Many of the sharp edges are now dull or dinged!! I wish I had ordered a few good US-made end mills instead...better to have a few supreme end mills that cut then two box fulls of useless end mills from Grizzly that need to be resharpened before I can even use them. Grizzly, what are you thinking? Very disappointing.

Proxxon 27100 Micro Compound Table KT 70 Review

Proxxon 27100 Micro Compound Table KT 70

The Proxxon KT70 is a great XY table. I have purchased two of them so far, for use as part of the Nano Gigapan project to allow us to take high resolution mosaiced images under microscopes.
You can take the knobs off and couple them to stepper motors fairly easily, and thus have an automated xy stage for a fraction of the price of equipment designed for microscopy.
The KT70 moves 1 mm per turn of the handles, and a 115x microscope has about a .75 mm field of view, so there is plenty of precision and accuracy in the KT70 for this purpose. In fact, the KT70 has 20 hash marks per revolution, so each hash mark is 50 microns. From my measurements the table has the accuracy to repeatably hit these marks.
That does point out one issue for Americans - everything is metric. 50 micros = 0.0019 inches - about 2 thousandths.
If you google 'Nano Gigapan' you'll find our project, along with examples of using the KT70 in scientific applications.
