Cut this Batman Fidget spinner on my Jcut 6090A router out of Polyethylene plastic - 8mm and use two 18mm magnets for the wing weights, the center ball bearing Size is a 608
with two thumb plugs pressed in from both sides to hold when spinning, Fun Toy!

Cool - 2 sided machining ?

One side machining, but rounded the edges with a buffing wheel, cut some for a friend of mine and he routed the edges with a small routing bit in his drill press.

Suppose you can make some kind of jig to hold the fidget spinner in place for routing the edges.

Got some 608 bearings, had no problem making a proper hole with a good friction fit.

Plug is a bit if a problem, file had ridiculous dimensions like 75x75", I'm in the process of trying to scale it down for a proper fit.
There seems to be 3 steps to this plug, any chance of posting your plug file to save me some headaches ?

I'm trying to make one out of corian, a little heavy perhaps but might give it more inertial spin action just from the weight.
I sliced the corian at .27, the thickness of the bearings so it should be a nice flush fit.
I don't see the use of using all the outer holes with bearings so I'll probably experiment to see what else I can fit in those, might even try leaving the arms solid.

I have discovered that corian is not the ideal material for these.
If the hole is slightly undersized to pound the bearing in for a friction fit, it has no give and cracks.

I cut a couple out of Elm, and out of a skate board top (shown - multi layer/colour) looked good. For the plugs, I used the center from the hole (tried the masking tape CA glue to keep them in place - worked great!) and then put the plug in the lathe and turned to a press fit in the bearing. Was pretty happy with the results.

Have had mixed results so far, having problems with the caps more than anything.
I'm picturing a male/female set of caps that fit snugly and into each other so they don't pop off so easy.

Am getting some friction, the material I am using is about .29 thick, the bearings .27, so I think the caps are rubbing the body a bit, causing short spin times.
Material I am using is the stuff they use at skating rinks for boards, helped a friend do a teardown of a rink and saved quite a bit of it. Is about 3/4" thick so I sliced it down to around .30, probably should have went a bit more.
Tried plexi mirror too, which is a bit thinner than the bearing. Too fragile for this purpose, probably too light too. So I'll keep at it until I get an acceptable design.

Batman out of Bamboo

Postby kp91 » Tue Sep 12, 2017 9:37 pm

Used a $7 bamboo cutting board as the stock for this spinner. I had to shrink the holes a little on the second try to hold the bearings tighter. The bamboo creaked a lot while pressing them in, but no problems.

I didn't use any tabs when cutting it out, after I cut the holes for the bearings, I put a dab of hot glue in 2 of the holes. I was able to route the outside profile without any trouble. It was a lot easier than sanding tabs off later.

Daughter #2 is a big fan of Bat Girl, so hopefully she'll get a kick out of it.
