Re: 60W: Cutting a match and lighting electrical t
Glad to be of assistance with the nipples.
As a matter of fact, I found out the hard way metal is a nono. That's how the output coupler cooler was cracked. The focal length on this lens is 7" so after a few feet it's dispersed enough to avoid any holes in my drywall. A shorter focal length will yield a smaller focal point (better cutting) but the smoke and debris (I also found out the hard way) collects on the lens which in turns absorbs the energy, heats up the lens and ultimately fractures it. So I opted for a longer focal length to alleviate that problem. I could have also used a nozzle with compressed air like most engravers/cutters use, but those are expensive, big, and ugly with a very small work area.
The irony is I have a mirror as a beam stop ;D
Also, good idea with the pork flesh. I already have planned soon: Ice, cardboard, glass, and ceramic as well. Any other requests?
