« Part 2: Tool bit Part 3 of Four layers ball series no next part

I’ve got everything i need to make a first hole.

I used some video here, advertisings are not mine, they are part of blip.tv – video hosting web site, sorry…


I have some liquid grip leftover, so I used it on the chuck instead of double side tape

Hole made on the end grain side of the ball

Two holes

I did not do any sanding or cleaning, the cuts you see are straight from the bit.

Drilling holes takes less time then to setup ball in the chuck :)

Yuri, intersting project. I can’t tell from the picture or videos what type of tailstock is holding the boreing bar. Your swiinging something off the bed of the lathe so it must be supported or the bar would tend to bend down behind the tool holder. Your holding the carriage to depth with your left hand and moving the boreing bar with your right. Is there any support for the drill chuck? I went back to look at your other projects, they are fantastic. I still can’t see how your swinging the boreing bar. Thanks

Dan, on the second video you can see how i’m swinging the “boring bar” using the modified radius turning attachment . I modified taig’s tool post to fit the attachment and to have boring bar leveled/centered. Drill chuck is used as a handle. I was not sure if the whole system will work so I didn’t bother making a longer handle. The tail stock from the first picture is actually removed completely during turning (i used it only to adjust centers)


$20 attachments pointed with blue arrows, two red arrows shows the modification i made to raise boring bar to appropriate height. “red thing” on the top-right corner is the shape of the tool post

Brilliant Yuri! I am really impressed with the clean cuts on the pictured balls. I really like your cutting tool too. I might try making some from some of the spade bits I never use. I haven’t given up on the Chinese balls, but I am currently exploring marquetry type work and having fun, so it may be awhile before I come back to the balls.

I realize that I will never get such a good cut as on yours with handheld tools, but I may discover a way to provide better support. But again, my first priority is to make some better quality cutters.
