One of the advantages of using the Aprilia wheels over the popular wire spoke wheels is that they incorporate a cush-drive to reduce driveline vibrations. Continue reading Motard Complete & Tested

Workshop Projects

It has been very busy here with numerous projects but the main project has been a new simple CNC router.

P1010604 This is based on the “Mostly Printed CNC” machine that has featured on Hackaday, Thingiverse and other websites. This is small 3-axis machine with belt drives on the x & y axis. The z-axis has been upgraded to a lead-screw and nut.
The purpose of this machine is to get familiar with the software & hardware before commencing work on a larger platform router and then on to a third machine which should be a solid steel frame for machining metal parts. Continue reading Workshop Projects
