Hi All,

I shall respond in order:

John: thanks for excusing George. I'm not easily offended and can take criticism. Even if its a bit left field.


George: I am intrigued by the 'CNC' category in Ebay. All the CNC stuff I found, including my own appears to be in

Business, Office & Industrial >
Metalworking/ Milling/ Welding >
Other Metalworking Tools

e.g. http://cgi.ebay.co.uk/CNC-PLASMA-GAN...ng_Supplies_ET

Is there a category Business, Office & Industrial > Metalworking/ Milling/ Welding > Other Metalworking Tools> CNC ?

or maybe Business, Office & Industrial > Metalworking/ Milling/ Welding > CNC ?

I couldn't find it. I'd be grateful for a link.


Robin: The tool will cut glass, so yes, it'll cut steel, stainless, DO1 tool steel, you name it. If you want a deeper 2nd pass, add a bit of Z. Maybe 10 thou but you should, with a bit of experimenting, be able to get the depth you want in one pass.

The spring rate is just one parameter. There is a pre-load grub screw in the end, plus you've got the Z to think of. The spring is *very* stiff. You need almost no pre-load at all for acrylic & ali.

BTW, just so we're clear, this is a 'drag' engraving bit. It does not rotate. You basically push it in as far as you need and 'drag' it around the surface.


Lee: I think I've covered your points. One additional thing though... as the tip is sprung you can engrave curved objects like pens, buckles, golf balls, pool cues, etc, without having to program in their profiles. Which is nice.


BTW must be the MYCNCUK effect but I sold one today! And to an American no less.


Cheers,

Wilson.
