This is the fourth vice I have bought and I must say from the beginning that it was the best choice I made. The design was promising (Kurt style) the size was appropriate for my mini mill (80mm) and the price was right (52 GBP).

It took a week to arrive from UK and as soon as I opened the box I tested it to see how it works.
It was hard to turn the handle and it was covered with a mixture of grease and oil. So I started taking it apart to check, clean and fine tune it.
First thing I checked was the parallelism of the body.

I was Happy to find out that sliding the DTI all around the body there was no movement of the needle.
I was impressed.
Since body was ok then fixing any problem to the rest of the parts is easy.
Testing the fixed jaw I found one side 0.05mm higher.
Using my dremel and a tiny sand paper tool I gently grinded the higher side.
Then I put sandpaper on the surface plate and with careful lapping I managed to make all sides parallel.

Next I noticed the moving jaw nut had an uneven surface

and it was pressing the spherical segment sideways.

A few passes with the mill and the nut took its shape.

Next I cleaned the moving jaw and the spherical segment that was covered in rust.

I lubricated all parts adjusted the jaw plates and the vice works like a charm
