The patent was in 1935 so it has expired. I was given the article by the author without a mention of an existing product. Done deal now and no way to detract it if there is a infringement. But I think 80+ years means it is expired.

jlchapman, I just ran across this article. Nice build. The design and drawings were published in Model Engine Builder in issue # 19. I have no objection to showing the build pictures although the isometric drawing of the winder and any other drawings are copyrighted by me. I'm OK about you...

I put a set of the cheap iGaging readouts on my lathe. They are spec'd to be within 1 thou over 4 inches. They are better than that and even if they just met the spec, that is quite good and usually better than my machining skills.

You need to make a series of tube stiffeners that can be clamped on the bar stock diameter. Use worm gear hose clamps to hold the stiffeners on the workpiece if you cannot weld tabs on the tube for clamping screws. The tab approach is better and stiffer. You should also mill out most of the...

I have the board files but I have never had a set of boards made so that may take a while as I learn what and how to do it. If you need a single ignition system, I do have a spare built system. I would sell it if you are interested. Let me know at editor at modelenginebuilder.com.

I have e-mailed Dave Sage, the board designer to see if he will either order more boards or release the board design files. The boards were constructed in China and are quite nice. I just built the last 3 of the 11 boards I was given by Dave or I could offer a few. Give it a few days to see...

I should also mention that the ignition circuit will also trigger from points or a reed switch. Both are nearly indestructible. The reed switch will function very nicely for single cylinder farm-style engines. Triggers with a magnet just like a Hall Effect Device.

Not to blow my own horn but we published an excellent ignition system in Issue # 34 of Model Engine Builder. David Sage and John Gedde are the designers. It will handle a V-8 up to around 10,000 RPM. Within the Bay Area Engine Modeler's Club, there are probably 30 of those systems operating with...

I'd call Dwight and discuss this with him. See post directly above yours.

Dwight Giles, the developer of the Black Widow, still has three casting sets available. The price is $1450 plus shipping. These are the last that will be available. His phone number is 707 648-71481, he does not use the Internet.

It is very possible you are going to be severely overcarbureted. Even the Black Widow V-8s run almost too rich on two fairly small Walbro carbs. But it will be interesting to see how this all turns out. Nice job!

Sounds a bit extreme to me. The Forums are great tools for what is really a fairly isolated hobby.

OK, if you say so. But it is morally incorrect to cheat a widow out of her method of making a living by passing the information on in a different media. Magazines in this hobby are marginal efforts and we've lost too many already. Let's not contribute to their downfall in any way, OK?

Sorry, but I think expressing the article in a spreadsheet isn't standing on the shoulders of giants but cheating the providers of the original work. I see no advancement of the science in this case and certainly no deriivative work.
