robert Posted February 11, 2005 Share Posted February 11, 2005 Never done this before but you might try black silicone caulk. It's very adhesive and would fill any voids around the axle where the rubber tire has divots missing. It would definately bond the wheel to the shaft, but use it sparingly and use laquer thinner to clean up any excess. (Silicone caulk is quite shiny when it dries, so you would want to limit it's visibility around the wheel) Link to comment Share on other sites More sharing options...
SiamSam Posted February 11, 2005 Share Posted February 11, 2005 Hey Bart - if I were you - I would seek advice from John Rigg on this issue. Link to comment Share on other sites More sharing options...
MetalRobotHead Posted February 11, 2005 Share Posted February 11, 2005 Looks just the sort of thing Plastic Padding would fix, sparingly though so it doesn't ooze out too much. Link to comment Share on other sites More sharing options...

robothut Posted February 11, 2005 Share Posted February 11, 2005 Normaly there is a metal part cast inside the tire that the shaft would press on to. Do you have this part? is it under the hub cap? just glueing the old rubber wheel to the metal shaft is not a great solution. but if you have to do it that way you might try some epoxie resins like Magic sculpt, it works like clay in your hands and turns hard as stone over night, so you could work the epoxie inside the wheel area and on the shaft, align everything up and let it sit over night then you could paint flat black any of the epoxie resin that shows. Other quick fixes might be to use a jell type supper glue and the spray fast set "Kick IT" that will set up all supper glues instantly, that way you can put the glue on hole the wheel just where you want it then hit it with a little KICK IT spray and its set, then go back and add more glue and build up a good bonding surface.

Joe K. Posted February 11, 2005 Share Posted February 11, 2005 And one more hint, bart. Whenever I glue/epoxy anything to a metal surface, I always wipe down that metal surface with rubbing alcohol. It must be as grease free as possible to help the adhesive to hold. Link to comment Share on other sites More sharing options...

bartzenegger Posted February 11, 2005 Author Share Posted February 11, 2005 another - it seems like there is only continuous wire going to motor!? not sure what red wire is doing?? Link to comment Share on other sites More sharing options...
bartzenegger Posted February 12, 2005 Author Share Posted February 12, 2005 im most curious about the red wire coming out from below motor, does that look right? Link to comment Share on other sites More sharing options...
robothut Posted February 12, 2005 Share Posted February 12, 2005 Does the green wire solder to the motor or the frame? in most cases one of the motor wires is soldered to the frame and that solder joint of the red wire and the blue wire floating out in the air just seems wrong so I would bet that at one time the red and blue wire were soldered to the frame. Look close for places that the red/blue wire can reach for signs of a small solder spot, or just try touching them to the frame with the robot ON and see if things do not spring to life.

bartzenegger Posted February 12, 2005 Author Share Posted February 12, 2005 thanks hut! green wire is soldered to the motor. red/ blue wire originally had tape over it , so unless it was tampered with that should of been right. although it just looks funky to me. - ill test your theory !
