Hi gang, I just met with a local artist who is doing some interesting work with copper vessels. She wants to attach beads of various sizes to the vessel wall,...
... One suggestion is to use a "back cut" "high angle" bit. you could also use a lube pump to flush the cuttings away faster. This would allow faster drill...
If you can get some kind of block or die lined up on the inside, a punch would be the ticket. Some kind of air cylinder could easily poke a punch through,...
I would buy a carbide PCB drill bit. The will last for 2,000 to 3.000 holes when drilling 4 to 6 layer circuit boards. What diameter are these "Vessels" ...
The vessels (which look a lot like ceramic pots) vary in size, from maybe a diam. of 6" to more than 18". The shapes also vary, but all have cylindrical...
... Speaking of which, do you still have some open laser time? I'm starting to think about the next Maker Faire (late May). My son is interested in seeing if...
I used to work for these guys http://www.kyoceratycom.com/ It is best to buy them in the std 50 pack. The price should be around $1.25+/-$0.25 per bit? ...
... You can buy re-sharpened used bits. ... yes I do I also still have the plastic you bought earlier. ... I think the chassis design looked quite well. We...
Thanks, Jeff. On their site, I found a speed/feed chart-- http://www.kyoceratycom.com/pdfs/80K_FS_CIC_Multiple_CLs.pdf What does the "Retract" parameter mean?...
If the copper gets work hardened, might it be possible to anneal it and get back to nice soft copper that merely gums up the drill bit? Can you switch to...
This is cool! Locae in a four block region - what sort of RFID are you using? I'm used to some with ranges up to 50 cm.  Rich ... From: Jean-marie...
I am not sure a big spark would make a small hole, but how about EDM? That can make very small precise holes, and I bet would work better then carbide drill...
Folks, I've been trying to figure this out and I can't. Is there a free (or less than $30) way to convert the data on a DVD to a wvm or mp4 (320x240) format so...
... Oh, That reminds me of something. I think the big video files on a DVD are actually mpeg. I think you can just rename the extension to .mpg and then see if...
Let's see-- 100coulombs/ .01 sec = 10,000 amps! That sounds like it would take some pretty serious hardware. Would it? I'm open to all ideas, and if...

I don't mean to waste your time with a distraction, just brainstorming here.... the complexity of the electronics would depend on the desired repetition rate...
