I don't post often here, but I have to say what awesome workmanship this is in PVC. Looks great Derek!
I've started a new robotics project and have been exploring using the grey PVC for the frame and some structural parts. It's been great so far. I'll need to do some pocketing in some places to lighten it a bit because this is very heavy stuff, but very easy to work with, cuts and routs well, and is very rigid. I'm impressed with the nice bends Derek was able to get. :) Good stuff. I've gotten my PVC sheet from Industrial Plastic Supply in Anaheim, CA: http://www.indplastic.com/index.cfm?id=%3C!id!%3E&fuseaction=browse&pageid=61 They offer several different sizes and lots of choices for thicknesses, and are a great company to deal with. Their regular prices are very close to the sale prices from freckleface.com, but offer free shipping with an order of $120 or more. I've used them for all my plastics purchases for the past few years and have been very happy. Also, I have a pair of those Globe motors as well. They were offered through eBay at one time, and later skycraft surplus had them. the R2 Builders Club was using them as a possible choice for leg rotation to achieve the 2-3-2 extension of the center leg, but the vertical forces are too great for the shallow gear teeth. They would be well-suited to your application though, since they were initially made to turn satellite dishes like a turntable. If anyone wants one (or both) I'd let them go for $45 each, plus shipping. Email me directly if interested.
