Spin boards are, as a rule, not very durable. This, combined with my desire NOT to hang a giant swing in my living room prompted my engineer father to redesign the spin board. He identified the problem with the floor ones instantly, saying “it’s the bearings; they’re terrible.” A week later, I had the object pictured above in my living room.
It has been such a HUGE blessing to us to have that board, that I decided to share the idea with the SPD community. What my father did, essentially, that is different, is that he used something he called a “trailer bearing” as the heart of the turning part of the board. This allows the board to spin EFFORTLESSLY (and, caution to all…very very very very very fast, so supervise like crazy if you decide to make one). My 100+ pound creature has not harmed it, not even a little, and we’ve used it since June of last year.
I was supposed to carpet it, but I bought a round throw rug and use that instead.
Here’s some close shots of the bearing and how he attached it. The first picture is the base of the bearing, the second is the hub, and the third is a general pic of the underside of the board. If anyone would like more information, email me, and I’ll see if I can pry some better details out of my father.
The link below is a VERY short YouTube video of the board in action. It’s from the very first time we “took it for a spin” without using it for OT, so mostly I let da Creature play with it a little. He’s a snidbit obnoxious if you leave the sound on, but you can see from the video (click on the link) that it is EASY to spin even a heavy child as fast or slow as his sensory needs dictate:
