MADBob Posted April 25, 2007 Report Share Posted April 25, 2007 My 1st practice/test run on some scrap MDF to test my CNC coding:Added spline shape for onza/tensile cranks and cut it in aluminium:Nice tight fit!Assembled to an old, used crank arm:This is my 1st design, will probably make more with improvements Comments welcome Quote Link to comment Share on other sites More sharing options...

MADBob Posted April 25, 2007 Author Report Share Posted April 25, 2007 Hehe thanks I would do one for burns, but I don't have one to take the measurements of their weird spline. If you have an old or broken one you want to donate.... Quote Link to comment Share on other sites More sharing options...
Walleee Posted April 25, 2007 Report Share Posted April 25, 2007 good job!!!!in the next few weeks i'll have something similar to showDid you make a fixture to hold the crank when machining the spline??? Quote Link to comment Share on other sites More sharing options...
MADBob Posted April 25, 2007 Author Report Share Posted April 25, 2007 Nope, just accurate measurements and NC code Quote Link to comment Share on other sites More sharing options...
Jsy Ben Posted April 25, 2007 Report Share Posted April 25, 2007 80g Impressive...polish it up and make it alittle thinner. Ps. A cheap design simiular (sp) to the Koxx bashring design would be sweeeet Quote Link to comment Share on other sites More sharing options...

MADBob Posted April 26, 2007 Author Report Share Posted April 26, 2007 Drawing in autocad: 1 hour - ishCoding the NC code: 2 hours - ishMachine cutting: 2 hours, cos I was very conservative on feeds and speeds, wasn't really sure what the machine/cutter could cope with.Yea Dave MDF but only for the test run. The real thing is 6082 T6 aluminium.Its on my bike now, and I've given it a few bashes Holding up well Quote Link to comment Share on other sites More sharing options...
