You are correct, ATF only requires serialized parts-which they consider a "firearm" to be "secured". But many things are changing rapidly and state and local requirements can be more stringent. I believe ATF also has a proposed change out for this. We are an FFL/SOT- lock everything!!! It...

I'll make a better tool this week, but for now this worked OK.

Thank you Friends! Bud, I used your suggestion - drilled a plastic "gripper" tool undersized and grabbed the CuW wire and pulled/wiped it down while spinning in a drill press, it did pretty good working it smooth. My trode is .0635" a bit thicker then you mentioned and the plastic tool let me...

Hello experts, A few weeks with my 1st EDM sinker, learning lots but figure you guys must have a sneaky/smart machinist way to straighten thin copper round trodes. When I set them up, I can get them 1-2 tenths runout at the tip, but not all the way along the z axis. I need to set them .9"...

When all else fails, burn it-EDM.

1. No experience w Yasnac, but have used Fanuc & old Mitsu w Ethernet 100% reliable. 2. IIS is unreliable garbage. 3. Fanuc loves Filezilla-never fails, can drip 100mb files 4. Never seen it happen in 35 years(DOS, Win3.11), maybe but more likely hardware works and software failed with...

Yes, from Mazak. SmoothCAM Ai - (they match it to the controller you have, I bought a new Integrex w the Smooth Ai control so SmoothCAM Ai version for me.) Check out youtube- it will actually write the CAM in mazatrol for you based on the tools you have loaded in the machine. It still won't do...

Also - you can buy the new CAM system which will let you program on your PC using the most advanced Mazatrol - its graphical and shows your part as you fill in the info. You can then "output" the code to your older machines. Its awesome. I bought a new Smooth AI Integrex - hasn't delivered...

Approach point - hit auto set. If you change any of the other settings i.e. depth or width, go back and auto set them again. (auto set will input "?" in those boxes and the control will fill them in with actual numbers after you run check or the program) the control will use those to bring...

I'm looking at doing the same in a bigger space, let us know what temp you can hold inside vs outside.

Lol, Marcus- I'm barely getting my fancy machine to make holes to size and your doing amazing parts manually. I'd love to see what you could do with this thing. Thank you for Bud's book- really helpful!!!! Makino installed the 10 mcode flushing option, we're short a few pieces of sheet metal...

Thank you Marcus & precisionmetal. This is definitely a learning process... I really didn't understand how quickly the graphite trodes wear. That's some really beautiful work Marcus!! Those trodes would be a nightmare to machine in a single piece, funny how breaking it up into multiple ops...

#1 - can be done in both modes. #2 - you don't need to but you can if you want. #3 - Yes #4 - don't remember

Happy 4th of July weekend Americans!!! We burned our first part, 2 counter bored 3/8 holes into a sine vise build from A2 - 58Rc. Now I really understand what you guys were warning me about. I didn't realize how much recast doesn't get cleaned into the filters, nor did I get how fast graphite...

1st test burn today!! Marcus, I see why you stressed good work holding, I hadn't thought to buy a quality vice for it yet my Kurt's are a bit too big, so I used my crapO, Amazon/China special "shop fox" vice ($58 and I got screwed...) which in my defense I bought only to hold parts in place for...

Wow, you have my brain working overtime again. Thank you Marcus. This really is a whole new world, its a different way of thinking vs milling or turning. I just bought Bud's book and Makino has been great, we'll have applications here in a week or so. Here's our 1st controlled movements, they...

Marcus, Wow, you are a wealth of info- you've been doing this for many years I imagine. I see, yes I was trading off easy access trode replacement for hopefully precision, and your right I have no idea how fast they'll get used up or how precisely I can cut them-graphite and CuW is another new...

No please bring the rain, I've have 0 experience and I really appreciate everyone's insights and responses. I was not thinking to burn multiple parts at once because of the tolerances, the 2 sets of trodes (6ea)was to have fresh ones for a lights out burn. I was hoping to mount my pins in the...

Thank you Marcus & Steve for the pictures & tips! --Steve I'll make the top plate thicker. AC & air filtration is going in shortly, the area is separate from the rest of the shop. Marcus nice vice, I'll focus on the repeatability. I was planning to burn dowel pin holes to locate the trode...

Well, here it is ready for install on Tuesday. We milled an aluminum piece, it locates into the t-slots with no play, each pot will be controlled by M code so we can back burn each station with suction. I was assuming we would need Rough, semi and finish electrodes. this would hold 2 sets of...
