Could you please PM me more info on how you did it? I have a 50 watt CO2 laser engraver and have been wanting to see if I could convert it to rust removal. Thank you👍

Nah,I was just ranting about all the negativity about the post on don't remove the protection,don't do this 'cuz it's dangerous,etc.,etc.I just wanted people to realize,what we do here is inherently unsafe if you don't use common sense.Every toy we play with/scavenge parts from here has warnings...

C'mon guys,it was a good instruction.You gotta utilize common sense in what we do,hell all the blue rays you guys took apart to get the diodes out say dont open the case!I just turned 50,I'm sure there are lots of you near myage that did stupid crap growing up(pennies,bullets on train...

I know it's been awhile since your post,but I'ma slow reader,lol.I have an answer to your quandry about the heat shrink tubing not going all the way to the diode.Although you had a warning about the use of the alligator clip:),a great use is for when you try to use heat shrink near a...

Do you have any schematics of the wiring posted on herre anywhere?I'd like to do a similar set-up if you don't mind me copying.Nice job either way!

I have one of them too in the shed a friend dropped and broke the mount on I had forgot about.I'll have to play with it when I get time and a decent laser built.Being a packrat has it's perks!

I definately didn't want anyone to get hurt,just give options for where to find one.I have one of those free telescopes that came from Marlboro a few years back(Now I know why they were free,blurry as heck,at least mine was)That I may just take apart to change the focal length to see what...

Thank You for the info.After a few nights of snooping around on youtube,I already ran across FML's Tunnel Gun,and a few Spiro vids,that's what gave me inspiration to dig out my old box of stuff from when I got the tube laser.I found a couple of motors like you showed from Jaseth plus a couple...

Hi, I saw above you had looked at Mouser,and possibly Newark for switches.Other companies I have used in the past for non-laser projects,that carry obscure parts are Digikey,Jameco,and Alltronics.Check them out.Hope to build some lasers of my own in the future!

I'd look around on ebay,craigslist,fleamarket,etc,and get the cheapest if not free scope and give it a whirl!

Thx for the reply!Even though I'm disabled,I still have a pretty full machine shop in my garage next door(lathe,mill,etc.)I may have too look at other pics,and do it the "cheapway" for me.I definately have to read up on lens,prisms,etc.,and look through all my junk drawers to see what can be...

Hello, I just joined today.This thing is Awesome!I know I have alot of reading to do on these forums to learn what the terminolgy is for a lot of things,but can you tell me about the casting that holds the lasers?Does it normally hold 3 beams at once,or did you modify it?Also,what do you call...
