Laser Etching Anodized Aluminum
I Have been a gunsmith for a couple years now and have had many customers ask about laser engraving on the lowers. any ideas on a system that is strong enough to etch or engrave on anodised lowers?
Ive been checking my broken chargers and most have NTC connect in series with the negative and then a 471kd07 Varistor beetwen pos and neg. Isnt that enougt? The NTC con will work if when temp is high (all currents) and Varistor will work when current is high and NTC is Hot and lower the resitansa is current is high? Only 2 component ans seems to be standard in most chargers.
Is there ANY commersial products i can buy instead of messing around with high voltage and current? Trying to run a spot welder but i trip all breakers under 20A.
You can always buy a cheap K40 laser for around 400 dollars shipped. It won't be nearly as nice as Epilog but it will do everything an Epilog will do. It has no DSP control however... and it does lack on safety (for example NO laser off if the cover were opened), and I'm having a little bit of trouble locating the starting point of the engraving (it led to some mispositioned stuff... Will need to add a laser pointer to help me with this...)
