You shouldn't have to swap the leads. I'm not sure about the other part. It's been too long since I built mine to recall exactly. I think I had a couple of wires backwards. But which one's I don't remember.With the fuse blowing when switching to AC wouldn’t that mean something is off with the bridge rectifier? Isn’t that what allows it to change between AC and DC? Someone also told me you have to swap the leads when you change between DC and ac is this correct?
I could use a better one also. Mine is super simple. I took a small piece of wood drilled a hole in it ran a piece of 14 gauge wire thru it and soldered that to a brass plate. I have a bunch of felt and just wrap a piece of felt around the whole thing, wet it with solution and I'm ready to go.I also built the same one. It should work great for you.
I'd like to build a better marker for mine, maybe out of graphite? Those of you that built your own, what kind of marker did you end up with?
Thank you sir! Check out Chris Crawford‘s plans. They are actually Bob Warner‘s plans I believe but cleaned up and made easier to understand. I changed this one to 12 V instead of 24 because 24 was going to burn my stencils. Also some of my parts were numbered different so it was a bit of a challenge but Chris Crawford’s site will give you a good starting point. That being said though I didn’t really save any money so you might be better off just buying one.Wow very professional looking, both machine and mark. Did you buy the plans or does he offer them on a site?
