One of these days, I'll complete the CNC conversion on my X1... Harvey

Not very, I think it works out to (and check the MG chemicals website) 5 microinches/minute. I remember leaving the boards in for about 5-6 minutes, which is what they recommend. I used old photo

The island approach really didn't require etching, it needed an xacto knife and a ruler. Etching time will be the same, as long as you have enough etchant. Think about that one, you have to go

Harvey, ? Yes, all good info. My Proxxon just arrived so I will been opening the little box and see what I bought. :)? I figure 8500 rpms will be fine and being it's a hobby I will be ok. I have a

That's right. I was reading your website about the markers. I will have to use my EBucks that should be here soon from all my ebay spending the last 3 months. I remember looking for those markers and

Harvey, ? I am a very careful person but I do appreciate the warnings nonetheless. How thick is the correct amount of plating?

Ok on the top/bottom posting. Nobody is complaining yet. :) My default trace setting was 15 and I had bumped it up to 20 so that sounds good to me. I have seen those "islands" you speak of and

Got it. Thanks for the clarification. Watching/waiting for the UPS man is like the old saying "a watched pot, never boils". I raked the whole front yard hoping he would show up but he will probably

Yep. Make the board with the toner transferred, remove paper whatever way you do. Dry board. Put foil dull side down on board, run through laminator (I do twice). Then I allow the board to cool

I had trouble with SHARPIE. and industrial SHARPIE where it would draw a little bit of black ink and that ink would wet the toner and dissovle the toner and the some toner would stick to the SHARPIE

I prefer to interleave where reasonable. For this post, I will. For the previous post, it was so long that without seriously trimming it, my reply would be at the very bottom. You get your choice,

You'll find, that just as in machining, the RPM of the press needs to be matched to the size of the drill. Slower is used (at least in part) for larger holes. The largest hole I've drilled with a

Thanks Steve. I feel better already. Mine is out for delivery so I should have it soon. Did you have to replace the belt yet? I wonder if I should order a spare or two for future reference. I have

I have a Proxxon TBM115 and it has served me well on drilling hundreds of PC boards at my fabrication shop. There are definitely better drill press setups available. But prices do get high. I would

Jim, ? I figured somebody was going to say that. :) I researched the other Proxxon setup with the high speed tool but didn't want to go that route for some reason. And I read some good reviews about

Received from Dave at 3/3/2019 02:41 PM UTC: The Proxxon TBM115 has a max spindle rpm of 8,500. Conventional wisdom is to use an rpm at least 3X or 4X as fast as that to reduce the chance of breaking

Ok, I see. I was a bit confused there. You are actually transferring the backing from the foils on to the resist. Not the foil.
