    Please tell us you've got plans in the works for this! There's no end to the amount of usefulness that we could get out of it. I'm about to start a new career in machining, and have been told time and again having a home shop to hone your skills while off work, especially when you want to build your own stuff, is indespensible. I would love to have a tool like this, if only to learn more about gearing and the math involved!

    A very nicely made example of this tool, I enjoyed your video and explanation of the workings of it. I have the Ivan Law book but have not yet made the Eureka tool, I have been using the 4 tooth offset method you mention at around 15 mins and have made many usable cutters with that system the last ones were for my milling attachment.DIY Gear Cutter: The Eureka Tool-screen-shot-01-30-19-05.02-pm.png

    Thanks tmoore4748...Ivan Law's book Gears and Gear Making has a set of plans on the last 3 or so pages of the book. I used these drawing to build the tool. There are no building details there though. The project is pretty straight forward. I am putting a construction video together right now as I took lots of video while I was building. It will be a "show and tell" video as there are lots of approaches to this build. Then I am going back to my grasshopper clock build for a bit (see my U Tube Channel) but will then make a 3rd video on the Eureka tool where I'll make an involute gear cutter with a button tool and the Eureka tool. Thanks again for your interest...bob

    A wonderful piece of engineering, need just to be retired for making pinions like that, I hope to have the time to make this tool in the future, now I'm just making it with a single teeth cutter which is really less elegant than with that solution.

    Okapi Thanks...single tooth gear cutters work just fine and it is nice to be retired and work on projects. I often wonder how I had enough time to stick work into my daily schedule

    There is always the same problem when you're working for customers and on old mechanisms with pinions, the relation between the costs and what your customer is able to pay…
    I can just take time to work on my own collection items but it can take years before I repair or just clean some of them.

    That's spot on...within my sight I have 5 nice clocks and in a drawer several old pocket watches...all saved for my retirement...3 of the clocks have made it to test stands and seem to be running fine...but this Eureka tool is just so interesting I took time from a grasshopper escapement build to get a good look at it...I'm retired and I still can't keep up...Man I'm having fun!
