It takes a lot of work to get to the stage of putting a bike project back together. Media blasting, sanding, de-greasing & ordering new parts. It can be tempting to rush but taking care in assembly will make sure everything works. It took a few trial assemblies to get the shims right on the QA-50 engine & transmission. Everything was fitting together nicely with minimal end-play. Then this happened…Continue reading It Takes A Lot of Work…
It may be quiet on the blog
Quiet on the blog but it has been busy in the workshop with a number of projects progressing. My VSCCS application has been approved in NSW and I am just waiting on a response from the WA Department of Transport. And the picture? Well one of the projects in progress is a rebuild of a 1974 Honda QA50. This is the engine casing after a quick bead blasting.Continue reading Quiet On the Blog but…
A new printer has arrived at Speeddevice.
Sorry for the lack of posts but the past several months have been quite busy relocating from the east coast to the west coast.
One advantage of relocating is it gives a good opportunity to reconfigure the work space and take advantages of lessons learnt in the previous workshop. Technology keeps involving and being able to incorporate some new ideas is always welcome.
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
This makes it very difficult to bleed the brakes but worst of all it is down right dangerous!
I was recently tasked with reconditioning a Honda CB-500 Four that had been left in the weather for a few years. When I saw the bike one of the first things that I noticed was the “front brake reservoir delete” or in simple terms a piece of Tygon tubing with a plug in it. I wasn’t impressed but had seen something similar plenty of times on the motorbike blogs and on race bikes.
Then when I went to bleed the front brake I had one squeeze of the lever (with the bleed nipple open) and then nothing. No brakes. No pumping. Nothing and the tube was still full of fluid. Continue reading Please Don’t Ever Do This!
I had a bit of interest in the YZ-125 powered go-kart so here’s a bit more information about selecting a gear ratio.
Here is a simple little housing I design for a connector adapter. The connectors were soldered to a small custom printed circuit board (PCB) but needed a housing to protect the board and prevent any contact with the copper conductors. Continue reading Connector Adapter
The new power steering cooler is working well. There are no leaks with the new hoses, fittings and clamps. After a typical drive on suburban streets the cooler is warm but cool enough to be held in the hand without burning (sorry no definitive temperature measurements at the moment). Here’s a picture of it installed where it will get plenty of air flow.
A recent inspection on a Holden Commodore revealed that the power steering cooler was leaking. The standard cooler is a length of 3/8″ steel tube running horizontally in front of the radiator. These are known for rusting and splitting or leaking fluid. Below is a close up of the part that was removed.
