Question about wood grain orientation for a one piece yoyo


#21

You could try a slightly thicker axle in addition to finding the right wood?

I did leave the axle thicker than average, but this the wood is just too dry and brittle for this application. I want to try it with a bit of maple next.

I’ve been assuming the Legend Wing is not hand turned. Is this the case @YOHANS or @yyfben2?

@glenacius_K they are turned on a CNC lathe from one piece of wood (No Glue, No parts and pieces)

CNC lathe? That’s cheating!!! :rofl::stuck_out_tongue_winking_eye:

@Myk_Myk In 1901 the US Government helped the Filipinos start a school called “The Philippine School of Arts and Trades”. The machinery hall was equipped with modern machinery to take them from hand carving yoyos from Caribou (water buffalo) Horn to crafting their yoyos from wood dowel. In 1916 they brought their crafts to the USA in what was described as “Filipino Cultural Day”. It was 10 years later that Pedro Flores would remember these lathe cut yoyos from his childhood and start Flores YoYo Company. You can read more about the history and evolution of the mass production of yoyos and see photos of the original lathes used at the Philippine School of Arts and Trades: http://www.yoyofactory.com/100years/

That whole page is great!

I’m fascinated by the patent drawings for the Spin Tops. Not sure what exactly the patent covers, but I would have thought tops spun with a string, would have existed for so long they couldn’t be patented.

Looking closely at the Legend Wing, it looks to be turned in spindle orientation.

That looks like the trick to ensure the axle remains strong. I’ll hopefully get myself a turning blank next week and give it a go.

Yeah! I love it!

I had no idea that the Legend wing was just turned from one block of timber, I just assumed that it had a separate dowel and that the halves were matched from sawn blanks of the same tree. I’m surprised that it is as strong as it is, I haven’t broken one yet!

I suppose it’s less fiddley to produce.

My guess is on a CNC lathe, a Legend Wing would be cut in seconds.
