The Octapult

If you’re ever so slightly geeky like me, this will be fascinating. Just look at the amount of work that has gone into building this machine. It’s got a great and relaxing rythm too.

Stolen from Raincoaster who stole it from defrostindoors

I did NOT steal it (for once). She emailed it to me, like: “here, this is freaky and pointless, so I thought of you immediately.”

Glad to know you appreciate my work! As far as I’m concerned, as long as the video is not altered from its original form (as seen on YouTube) it may be retransmitted freely.

Brad – Quite simply, It’s awesome! How long did it take to construct?

The design phase took about a week, as I recall. I do most of my design on the computer, using a 3D modeling/animation package. Actual construction took another month. After a year on site, however, I wasn’t happy with the reliablity, which was hampered by two factors: 1. not being varnished, changes in humidity played havoc with the tight tolerance mechanisms, and 2. a tight timing design didn’t allow for a wide variation in transit times between the cones and the loading gates.

So, I brought it back into the shop, last summer, varnished it, and added an indexing mechanism at the gates, so that a ball would always ready to load on time. Consequently, instead of circulating six balls, it uses fourteen, and works much better.
