RE: How to start - Nikon1975 - 03-05-2018
I found on Amazon some KF 16 L and KF 25 that are discounted as were used for display. I'll see if I can find something like this at the factory. The KF 25 is the smallest that guarantee a runout precision, although is not a table top machine and it would force to rearrange my room.

The Discount was a scam. Anyway, do you have any experience with products of a company called Groz ?
Thanks,

I've read a little bit about Groz and the reviews were all positive.

For the selection of the vice, is the angular movement needed to make cut like the one in the picture ?

Or it is better to have a flat vice and use an angular cutter ? What are the benefits of the vice with the swivel head ?
Thanks,
Davide

Have a look at Tom's videos. In this one http://tomstechniques.com/clamp-knurling-tool/ he shows a number of different ways to set up an angular cut. I don't think you would use a vise swivel base for the type of cut you've shown.

Thanks,
More questions: what's the difference between a precision vice and a normal heavy duty vice ? Looking at the Bernardo catalogue (but I see the same in other producers) there is the PS series and the KV. They look the same to me. For the FJ I see the benefit of the wider opening, mostly for my applications, working with front panels.

The precision vise is less likely to have the movable jaw lift when you tighten your work piece in it. And it should be machined to tighter tolerances. I'm sure there's more to it though.

For front panels you may want to just clamp the sheet to the table with a spoiler board behind it. Thin stock will buckle with the sideways pressure from the jaws.

You also want smooth jaws on your machine vise. The checkered or 'knurled' cross hatch found on bench vise jaws will ruin the surface of the part it's holding. They are also less likely to be straight and parallel.
RE: How to start - Nikon1975 - 03-10-2018
Thanks for all the answers, precision will be. Will decide between the wide span and the normal. I think it's also worth to but a set of the thingy to clamp parts directly on the table. How do you call them in English ? These, do they have to have any special features ?
