That setup should be adequate, are you sure you're not being too violent with your cuts?

Pretty sure, never took cuts deeper then 1mm at a time.
The problem it's I have difficulties at clamping the big vice so it's parallel with the mill table traveling... Also it's not perfectly leveled. Should I buy a new vice?

Does this mean your clamping methode is interfearing with the travel of your mill table?

The vise is not squarely built?

Is your table magnetic? (for setup trouble shooting)

No, it's just when I try to mill a slot on a block/tube I can see it not parallel to it, so it means the vice it's not mounted square.
The vise is not squarely built?

Don't know, the small vice it's square I'm sure but the base vice it's just a regular drilling vice I bought a while ago.
Is your table magnetic?

No, just the standard milling table of sieg x1

I would loosen the vise mounting with a workpiece clamped in it (a piece as long as the table) and have a bit in the chuck then use the ends to square the vise to the bit. Then tighten the vise mounting, then recheck the distance to be sure it didn't move. Then make a test cut...

Of course the workpiece has to be straight. You could even use a carpenters square on a good level.

Not really :lol: lack of planing now clearly give me headaches...
However, I learnt some precious experience with this so the next one I'm going to make will be much better :)
Can't wait for the rotating table to arrive :D

Looking very good. General advice to everyone, if you're really into making stuff and have a couple thousand dollars to spend, get yourself a lathe and mill - it is easy to teach yourself, and with a bit of dedication the tools will soon pay for themselves.

Save as much as possible and get something decent, I'm already finding the length of the bed, chuck dia of my lathe and the general size of my mill disturbingly small.

Depends, not here. So far suppressors are the only thing that has a bit of market.

I remember saying something about this when you were first looking for advice ;)

Seek and you shall find, when word gets round that you can make custom parts people will come to you :)

Yeah... But sometimes reality and pure numbers aren't the same thing :P anyway I'm saving again so next summer I'd probably switch gear :D Also it's short of a addiction, bigger the better :lol:

Recently gained access to one of these:
http://www.mini-lathe.com/C6_lathe/C6/c ... troduction (04/18/07)
I have done a lot of basic work on lathes in school metal work but understand i have a lot to learn.
Anyone suggest any basic projects? or got any simple designs for hammer valves etc. to look at.

also have access to bench drill, arc welder and a lot of general equipment

JSR will suggest you to make a pengun.
Do you have the milling accessory for the c6 lathe? If you do, it's possible to build a PCP. The book "The modern pneumatic airgun" by H.M.Burckly will help a lot.
