indexing ring without a dividing head, back to basics. Making the feed screw block and indexing block. milling in the lathe, 4 jaw chuck work and knurling.
What a nice dividing lesson with paper and a pencil and a lid interesting lesson for me. Great chamfer to bar radius confirmation without (I think) removal of the material in the chuck. Fortunately these two American watchmaker guys use metric only industry standard so enjoyable to follow not having to convert along the way. We are liking your tool a lot, thank you for sharing your build.
excellent project, i've learning with you. I wish have had a teacher like you, technician school in brazil-São paulo. Thank a lot teacher. Você é o cara!
very nice device i builded myself a tool and cutter grinder without any plans from someone else and it works quite good thats why i have great respect this is not an easy Project but very satisfying sharpening the end mills and other tools by yourself at home i needed months of thinking comparing ideas and planing the building itself took only some hours after i was sure which ideas to prefer...
Easy way to get a sortof accurate device. Hopefully a very loose tolerance was okay for it. As the lid rotated (2:27 to 2:50 and beyond) it was obvious it wasn't centered, thus a maximum of two of the dozen points would be accurate.
I like you used things I Learned in 7th or 8th grade algebra class now days 3rd grade maybe. If the divisions are small like three you use the angled side for the strip of paper? Thanks for sharing
Hi Valdimir I will try to explain The top line is the circumference of the lid. The line from the circumference down can be at any angle the important thing is the length so you can mark the 12 divisions as big as you wish.The last line is from the 12th division back to the end of the circumference. This line gives the angle for all the other marks. Copy them from the bottom line onto the circumference line at the same angle i.e parallel to the 12th division line. Regards Alan
Wait wait wait wait wait wait wait. Why in the heck couldn't you just take the strip of paper that you cut and tape down draw a line on it and divided into 12 increment starting with one Edge? You would have got the same exact thing
enots engineering lol ! Yeah I didn't think of it that way that is 12 equal parts. It's actually quite simple when you put it like that I wasn't thinking that through

Geometric constructions - "When am I ever going to need to do this in the real world?" - Heard my kids say! Nice build so far!
Thanks
I did say back to basics

Thanks for watching
Amazing tip!
Very cool
Very nice device for small parts... :D
Thanks

Thanks Sam
I remember thinking whats the use of algebra.

Why the line is with an angle to the line on the sample? which angle?

Sweet
Thanks
having made the Hemmingway tool an your design yours is hands down a better tool
Thanks for your comment

Hi
This method is simple. Try dividing a strip 152.652 mm long into 12= 12.721 mm per div plus any error per division will accumulate.
