 The sword is only as powerful as it's beholder. But if you choose the labview sword you won't get much tech support at regionals. - xXhunter47Xx [more] |

Re: pic: Dual FisherPrice Gearbox
I am using a 12 tooth 20 dp gear press fit onto the fp motor shaft. I am indeed mounting the motor straight to the gearbox.
FP's have a free load rpm of 15700. 15700/48=327 rpm. Hmm... I came across the rpm limit in their catalog too but disregarded it. rpm for first stage- 3768 rpm second stage- 1055.04 third (idler)- 295.4 fourth (output)- 328.2 rpm It looks like the first one will definitely need bearings but the other three stages will not. This gearbox is for an off season upgrade so every ounce counts (to comply with the rules anyway) We weighed in at 117.8 pounds and are also planning on adding fiberglass struts with powered rollers for the manipulator (maybe). Thanks for the correction. -Vivek
