First of all: I'm NOT so familiar with the US/UK-milling-terminologi !

Is this called a PLAIN milling cutter ?

I think it was the right cutter to use to the job, but unfortunately I destroyed it because of the plasma cutter had hardened the steel too much for HSS tools.

I now have to arrange some grinding rig to get it sharp again - but it'll have to wait.

I then used a big "end cutter" - I think it's called - and it gives me two problems:

1) a much more rough surface - witch you clearly can see here:

2) it's not big enough to cover the whole width of the peace, so I have to mill it twice - and you can clearly see the "ridge" here:

- you can SEE it but you can't FEEL it !

The PLAIN cutter didn't give me this because it was so wide it covered the whole peace and the surface was nearly ::) like a mirror.

Darren:
Hi Ksor,

The first cutting I think here is called slab milling, or side milling on a vertical mill. The second as you rightly say is end milling.

That slab milling of yours gives a wonderful finish :clap:

How did you cut the dovetails, I'd like to see the cutter that did that so well .. :bow:

ksor:
Here is the cutter I used instead of the destroyed slab cutter:

I called it a "very big end milling cutter" - is that the right term in US/UK-milling-terminologi ?

And here is the one I used for the dowtails - and I cut each of them in one procedure - 25mm X 15mm.

Darren:
They look like some serious tools you have there, I see now why your dovetails came out so well :clap:

Thanks for showing.

There seems to be a lot going for horizontal mills, if it wasn't for the room I'd consider one but I have enough on my plate .... :lol:

Darren,

You should be able to get a right angle head for your Beaver, I saw one for sale the other week on one of the second hand machine retailers sites. Not cheap though. Maybe a standard Bridgeport one would fit.

I am going to Chester UK in a few weeks to have a look at one to fit my mill. But the dovetail attachment will need thicker gibs, because mine has a narrower mounting. Should be a fairly easy mod job.
