    I turned some yo-yos

    (part 1 of 2)

    Sunday Dec 4:

    I started to make yo-yos for three children on my Christmas list but ran into a snag. With luck, they will be finished tomorrow. Lee Valley sells a kit (catalogue number 88K161) that can be used to make a very good yo-yo and one needs a lathe for the project.

    Mack Cameron agreed to let me use his lathe today and Don McFarland his neighbour in Brooklin agreed to help to train me.

    I have not used a lathe since high school and the lathe that I used then was a metal lathe.

    In preparation, I cut blocks from four different types of hardwood –cherry, walnut, maple, and jatoba then drilled a hole (35mm by 10mm) into each.

    A brass hub from the kit was epoxied into each hole then eack block was cut roughly into a circle on my tabletop bandsaw:

    Mack started turning but soon let me take over:

    I found the turning to be quite straightforward and made fewer mistakes than I expected to. After turning the side to the shape and size that I wanted, I sanded the wood starting at 150 grit and working right up to 600 grit right on the lathe (at a slower speed).

    The walnut sides looked really good:

    But, with the axel mechanism in place, they were too far apart:

    What was the problem?

    Upon closer examination, Don and I figured out that I had glued all the hub mechanisms into the wood blocks upside-down:

    There was nothing I could do except to split all the blocks apart with a chisel to extract the hubs

    clean, the dried epoxy off the hubs as best I could, make new blocks, and glue the hubs into those blocks with the proper orientation. I did all that at home this evening and will be going back to Mack’s place tomorrow in order to try again.
    Cheers, Frank

    Monday Dec 5th:

    I finished three yo-yos at Mack’s place on Monday and it took me about four hours to do so. I sure wouldn’t make any money at that pace. I ended up one making the cherry, maple, and walnut versions. I turned the jatoba one a bit but ran out of time. Also I don’t really like to look of jatoba and, if I decide to finish it in the future, I might find that the yo-yo is too heavy.

    The two hubs are joined with this axel assembly (which includes a ball bearing among other sub-parts):

    I managed to brand part of my name onto an inside surfaces before assembling the yo-yos:

    Finally, I got to test a yo-yo –and I am happy to be able to report that it performs better than any yo-yo that I used in the past.

    Looks like you had fun with the guys Frank. Hey that is all a part of learning. I still do things like that. Post your yo-yo's when you have them finished.

    A project and a meet up! That's great!

    And I'm no pro at the yo yo, but I do love those ones with the 'intelligent' hubs... Very nice...

    What a cool present Frank. Good of Mack to let you use his lathe. Must have been a real pleasure learning on a great machine line that. Wow just ocurred to me that was all Canadian...machine, yoyo parts and lessons.
