	Here you can see the pan/tilt head constructed for more elaborate time-lapse imagery: And the first resultant video from it: There seems to be a lot of rotational jittering caused by the compression on YouTube.  Compare this to the video here (3.6MB) to see what the original looks like.  This will be much more interesting with some background audio bed, but you can only do so much in one day. Here is my letter to the person I borrowed the original design from: "I used a nylon spacer, Hillman 0.562x0.375x1/2 (#880443) Nylon spacers, from Lowes, sanded the outside down slightly, put three groves into the inside of the gear using a small triangle file, then press fit it into the gear using a wood block & hammer to jam the nylon sleeve in. Then, I took a spare 1/2 bolt, heated it up just enough to slightly melt the nylon plastic, then began tapping the nylon spacer with the hot bolt. It didn't take to long but now I've got a gear with a very snug nylock nut sort of fit. The rocking you see in the head is due to my crude Dremel machining of the wood to make holes for the Lowe's: Hillman "For ACE pump bearing" #99502-H. There is a 1/32 of slop between the bearing in the head, so that accounts for a tiny bit of rocking. I forgot to put thick plastic in between the pump bearing and the tilt bearing. I'll fix that oversight soon, though. The main source of rocking comes from my too-loose hole drilled for the vertical 1/2" bolt, and my not-so-flat cut on the nylon spacer used to hold up the head from the bearing in the base. If I put a thrust bearing on the head from vbx.com (thanks) to spread the rocking load instead of being only on the 1/2" bolt, that would cut the rocking back and forth dramatically. Making a tighter hole for the vertical bolt will improve things even more." Back to articles
