If it is any consolation it scribed and cut out in under 10 minutes, should be a quick task to check off.

I'm glad the floating head worked out for you. Don't forget I will need to add the time making one of them to the 10 minutes...

I've got some plans I could sell you

HaHa, I just told the missus I didn't know how to make one...

If you don't tell them in the first place you don't have a problem. :laugh:

Some pics of the table. Excuse the cables drooping everywhere, like I said earlier there is a lot of tidying up to do.

The two drums hold a total of 60 litres and the water is pumped up with air pressure and drains with gravity. As you can see I am pressed for room in the single vehicle garage. Cutting will be done outside so the table will be filled and drained for each session. It takes about 2 minutes to fill and about three to drain.

I have gone against the majority recommendation and directly wired the torch switch to the 7i96, it is only switching 18V and I have faith in PCW's design (plus a few spare inputs). So far so good.

Thats a tidy little table Phill,

I was going to go with a compressed air water height on mine but I changed my mind after making the first tank as I was worried that pressurizing a large steel tank could kill someone if any of the safety valves failed. I ended up with a 1000 l/m pump instead.

But on a smaller table it makes sense to use air pressure.

Is the table on castor wheels?

Yes, it is on castors.

The pressure for the water is only 1.5 - 2 bar.

My problem was I did not consider the safety factor of having a untested pressure vessel used in a workplace. Getting a tank 3000x1500x300mm tested is not cheap.
And a small amount of pressure over such a large area can cause problems. Especially if it were to pressurize up to our shop air pressure of 110 PSI.

But for a hobby machine is makes perfect sense. Especially when your the only one using it and you know what your doing.

I can understand your concerns.
I will be the only one using it but I'm not sure that I know what I'm doing.
When I get the water to the correct level I unplug the air to be safe.

What was me when I first started using my machine. I had never use any other CNC machine before apart from my robots. When I first started cutting I did not have any cut settings fully sorted and I started cutting a 20mm plate for a job. I think I only got about 3 good parts out of that 3000x1500x20 sheet. A very expensive learning curve. Looking back I would of done things differently but I learnt a hell of a lot.

Looks good Phill. I had a setback with my watertable as it had a leaking weld. I got as far as putting the tray in the back of the ute but had no time today to go and get the boys to reweld it (after all, I paid them to do it).
I've kinda half been looking for a tank of some kind but it needs to hold around 125 litres minimum.
