Try a two part isocyanate/polyol polyurethane foam mix. We have just bought a machine to make parts with this stuff, having been outsourcing it. It basically comes out as a sort of synthetic rubber....

That YouTube video is very neat. I've been thinking about making a PCB printer for a while, and this (very long) thread probably answers a fair few questions. I know what I'll be reading these next...

Free energy machines come in the two types stated previously:

Fake on purpose
Fake by accident

Purposeful fakes want money to sell you the secret or the device, often lots of it. By...

I see, it's your webpage. Nice looking machine you've built.

I've just bought a very basic 4 speed wood hand lathe, so now I'm looking around this section for the first time.

It could be that your driver board is crashing because the hardware in that can't keep up with the data rate from the faster computer. It shouldn't happen due to the bottleneck of the parallel port,...

You could also try shading the compressor, as a large compressor tank will catch a lot of water as it cools down after pumping up, eventually getting full (which leads to other problems) You might...

Personally, I buy the cheapest damn power tools I can find, and simply buy two of them. I have, due to this, four 24V batteries for my 2 24V drills, 2 12V batteries for my two 12V drills, and 2 18V...

Well, I'm simply watching a (very long) thread http://www.cnczone.com/forums/showthread.php?t=14100 on low cost laser engravers, and chipping in once or twice.

Like many, I have little time, I'm...

Aksess, once it goes via a reliable local distributor (as I'm sure Neil will be) then any issues become his problem when you buy Chinese through them, rather than direct. If nothing else, it gives...

I know you don't need a license or anything for a high powered laser in the UK, but you do need to consider the HSE.

For cutting stainless you will probably want/need an O2 or air assist, and at...

hkxy, your website isn't very helpful, as it isn't in Latin characters, let alone English. All I see is ???? everywhere, and some nice pictures.

Is there an English version?

Thanks, Neil.

To avoid a lot of the HSE laws you could provide the parts as a kit, with a power supply, laser tube and table all as seperate items for home assembly, in the same way as kit car...

Long thread! Yes, KITT needs a computer controlled nitro system, and a button on the dash that says "Turbo boost".

Back on topic, is the UK distributor site up yet? I'd happily buy a UK based...

If you make your own on a machine, don't forget to keep it cool.

Personally, I would use piano wire and a hand file. Start with the right diamater, then work carefully, it shouldn't take more...
