informationadWOW, its been a year since the first build off! Where has the time gone! This year I think I will feature the resurrection of a dead torso and the problems that can and do occur with fiberglass. My original TimK torso that was damaged by a local paint shop here in Dallas. It was a beautifully prepared torso when it went in for a show room finish. We had added the SEM bumper coating material for the orange peel texture effect. Apparently that had a reaction with the solvents in the paint that was used. It caused a cascading reaction which melted portions of the torso. In an attempt to fix the problem, the paint shop dug into the gel coat into several areas further damaging the torso. Months of work and Bondo sculpting were ruined. In addition to that it looked like the torso had been dropped because the bottom of the torso had an impact fracture and raw fiberglass exposed (which they denied). We are going to show you how to fix that!

Most of us have used Bondo or similar products but most do not use it correctly and get suboptimal results. Unless you are a paint and body expert most simply do not have the exposure to master the use of this product and technique so this build off should help to select the correct product and how to use it. As we start to make our B9’s mobile we will start to see stress cracks pop up if they are not prepared correctly so we need to prevent this before they start to show up.

We will cover:

  1. Torso prep
  2. Bottom ring support to prevent stress fractures
  3. Donut prep including truing the donut for the rockler bearing and trimming it for twist locks.
  4. Selection & Proper use of Fiberglass Resin/Epoxy, Bondo, Dynaglass, Evercoat, Kittyhair and glazing putty
  5. Electrical setup of the B9 to allow for simultaneous AC and DC usage safely.
    • This includes a detailed parts list and schematic to disengage your motor controller when your robot is charging so he wont take off on you unexpectedly while still being able to entertain the public safely.
  6. Use of the CF3 sound system and the 12 channel RF
  7. Roboduino programming and use in your robot
  8. Using RC relays for remote activation of robotic functions
    • Remote control of the Soil sampler
    • Remote control of the claws and arms
    • Remote control of the bubble lifter
  9. Making Collar Ribs and Vents with Acrylic stock & Jigs
  10. How to prep and use the Replica neon back plate
  11. How to assemble the Brain cup and Finger Light assembly
  12. Copyright & Licensing issues. Fact vs. Fiction.  An open discussion on what you need to know when you take your bubble headed booby to conventions and organized events.
  13. Live Web Chat with Dick Tufeld on Saturday.
  14. Droid races – for those that dare!!!
  15. The entire event will be be viewable on web camera and live chat at
  16. Plus tours at the machine shop, paint and body shop and polish shop (for those that need their domes nice and shiny)

    Are you, in fact, located in Texas? It’s hard to tell from this site. But I was wondering if you are local. And if so, I wondered if your droid ever makes party appearances??
