Hello,

Just received a new 4" size machine vise.

It is a Kurt lock-down clone made in Taiwan and sold under the brand Knuth.

Model number is PMZ100:

At 400 EUR shipped is not the cheapest, but it is half the price of a 100mm Gerardi.

The build quality is very good. Ground surfaces on all sides. After cleaning and oiling everything moves smooth.

First impression is very good, but I must still check the perpendicularity and parallelism of all surfaces.

BTW, can anybody give some info about the Knuth brand?

Made more progress with the vise.

Bolted on the table and measured how parallel the ways are to the table. Result: 5 micron difference (0.0002") over 100mm distance.

When fully tightened both jaws lift 15 microns (~0.0005"). But the lift is identical on both jaws, therefore should not be a problem.

All in all I am very happy with the vise. Build quality is very good and for hobby use is perfect.

Initially I wanted a 100mm Gerardi which clearly would have been better, but at almost half the price I decided for the Knuth and will invest the difference in tooling.
