The CFL issue is interesting.

I bought one that is turned on for say 30 minutes every day and it's worked since about 1993. It gives out a good light and doesn't flicker, etc.

The rest of the...

Infantry11b,

You've hit the nail on the head; too many people. The earth and its resources is a finite commodity and we can't simply keep doubling its population without dire consequences for all....

Thanks Jim. Your feedback, as usual, is appreciated.

Cheers,

Thanks Benderart.

I wasn't trying to give Jim grief only trying to clear things up. I consider Jim and Tom to be absolute legends for the home brew machinery set and their equipment, opinions and...

Thanks for the speedy and informative reply Jim.

The Powermax 85 list price for US customers is $3,890 USD ($3,635 AUD)and the list price for the export model is reportedly lower.

A typical...

Dear Jim,

Are the Powermax units sold in USA able to be used in Australia as is or are the units exported to Oz somehow different?

Given the favourable exchange rate, shipping from the US could...

Looking good.

How come everyone else's sheds appear tidier and better organised than mine?

Back to the idea of a rotating jib type table where instead of an X and Y axis, we have a swinging jib with a torch that runs along the swinging jib. Whereas the normal gantry setup requires the...

I agree with your crown idea Tom.

As a kid on a farm in Western Australia we had a lot of machinery and equipment driven with flat belts. Invariably the pulleys were not flat but had a slight...

I'm just a lurker and haven't built a table yet, however I've devoured every bit of information on this sire and others.

Is the direct drive setup an issue? How far does the X and Y axis move for...

Looks like you blokes had a good time.

Are there any CNC hobbyists in Perth and do they have similar gatherings?

I am presently designing a 2 x 3 metre plasma table and will use servo motors to drive timing belts for all 3 axis.

I am in a quandry as to where to mount the motors. I was going to have a servo...

Bekx,

Just had a look at your build pix. How come your shed / workshop is so tidy and uncluttered?

You're a disgrace to the home tinkering profession. By rights your shed should be...

In Australia we are looking down the barrel of a federal election. The left wing party has been in opposition for about 15 years and look as though they might get back into power based somewhat on...

gmatov,

All that thinking and nutting things out willl at least keep Altzeimers at bay.

Your kids and grandkids must be proud of ya!

I agree Greolt.

Gerald D's design and presentation are spot on. The machine looks fantastic and many are charging for inferior designs.

Keep up the great work Gerald and don't be diheartened....

Have a look at Jaycar - Australia for a stepdown transformer, however I think their biggest 240 - 110 stepdown is 1000VA which translates to about 9 amps @ 110 volts (I think).

Mike,

The concept of a water table is attractive in that it captures dust and smoke and reduces material warpage.

The downside as I understand it is the rusting of the support slats, the...

Abomination,

At least with my approach to fun means that you have some fighting chance of avoiding serious injury, even if it means standing very still and trying to not make the rabbits look...

I'd rather get into a cage full of hungry dingoes naked with rabbits tied to my wedding tackle!

Black Hollow,

Your workshop is very neat and tidy. It puts mine to shame.

Dear Millman,

What type / brand of bearing is the one used for your gantry pinion shaft and where do you get it?

Obviously it must have a bearing each side and provide sufficient support for...

Awright,

The water table mentioned is a shallow tray / tank about 6 inches (150mm) deep in which the metal supporting slats sit.

The metal to be cut sits on top of the slats and either just...

What sort of money are we talking?

The pack rats are the survivors. I;m in Australia and come from a fine line of pack rats. I'm presently in the acquisition phase and hopefully I will reach to making something phase, before I die.
