After a few decades of sitting around the carb on the little Honda wasn’t looking so great but with bi-carb soda in a media blasting gun the parts were cleaned up to brand new condition in no time.Continue reading Honda QA-50 Carb Clean-Up
A new printer has arrived at Speeddevice.
I recently changed the stepper drivers on the MPCNC engraver/router/plotter. Previously I was using a Gecko G540 but I want to save this for another project.
Three TB6600 stepper drivers were purchased and a new power supply was wired up. Continue reading CNC Stepper Drivers
The MP CNC (Mostly Printed CNC) is now working and being tested as a pen plotter before attaching a rotary tool. There have been some interesting problems. To find out more about those and my recommendations read on. Continue reading MPCNC Testing
It has been very busy here with numerous projects but the main project has been a new simple CNC router.
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
The APRILIA RS-125 caliper has finally been installed on the Honda CRM-250. The brake system has been bled with a quality DOT-4 brake fluid. It now has a solid feel (though there is some sponginess due to brake hose expansion – this may be replaced with a braided line) and no leeks in the system. So far low-speed testing has been carried out with further testing to come.
With the development of so many consumer, DIY and kit CNC mills, lathes, Laser-cutters, 3D-printers and other assorted NC machines that line our wishlists it can be easy to forget that a lot can be accomplished with manual tooling.
Some good news, a delivery arrived with the fasteners needed for the sprocket and brake bracket. Nice black finish high-tensile metric capscrews and countersunk socket screws.
Recently turned a few spacers on the lathe for the CRM to motard conversion (see earlier posts – CRM 250 with Aprilia RS-125 wheels & brakes).
The fabrication of the motard bracket, to adapt the Aprilia RS-125 radial mounted caliper to the Honda CRM-250 front forks, is now complete and the results are quite pleasing.
