Thanks, Jack. I was beginning to wonder if anyone was still out there! And please send me details about your mill-drill electric feed system. As you know, there are people out there converting these mill-drills to full computer controlled complete with ball screws and programming, but they are a little out of my league.Jack Gifford wrote:Watching your persistent progress is enjoyable.

To avoid breaking those fins, you need to add a small/cheap (less than $60) electric downfeed to your little mill, as I did. Thanks to an $8 pulse-width-modulation circuit board, I can dial it down to less than .001"/second. I included an adjustable down-limit microswitch, so I can walk away while it finishes its s..l..o..w cut. With 5 minutes work it can be moved to the X or Y table feed, also (although no limit switches- yet). It's been invaluable- couldn't live without it now.
Thanks for the thumbs up Beat. You know how much work it is to complete a project!beat wrote:![]()

Yes, a cushion on there would help. But the wife told me last night how much I had already spent so that seat will continually remind me.skippy wrote:It looks really good. The seat looks a bit hard thou.
Stan, we're still looking forward to your next build and I hope your new "Indian made" new parts have a good warranty!HPbyStan wrote:I'm liking it Tom !!
Jack, I'm using two 6v coils in series which is what Boyer recommends, or a dual output coil. But I can't tell you the question about the electronics. But think about all the 4 cylinder bikes out there. They usually have just two dual output coils and spark 2 cylinders at the same time (wasted spark on the one on the exhaust stroke).Jack Gifford wrote:Looking good!
Although I spent my career in electronics- I'm left with some questions. Such as- if two spark plugs are both connected to the same coil, would they ever both spark?Seems likely that the first one to begin an arc would drop the voltage too low for the other plug to spark? Are two coils required to have them both consistently spark?
Thanks, John, and the reversed color scheme works really well when the front and the back of the tank were "modified" by the previous owner.johnq wrote:The reversed colour scheme works great
That's how they work.Jack Gifford wrote:So... apparently a "dual output coil" has two discreet secondary windings, as opposed to merely having two "outputs" of a single winding? [Do me a favor and put an ohmmeter across the two outputs?]
