File the quarq or the rings?Xplora wrote:I'm going the Full Retard, Tropic Thunder style. Quarq has advised that you can file down the proud edges on the earlier Quarqs to use the Rotor Aero Q-rings. Biggest issue was that you can't use a 52 at all without the modification. Just needs a proper calibration bwahahahahhahahahahahahahaha so here I go

fluke I tells you.biker jk wrote:Serviced my Shimano hubs without dropping any of the ball bearings. The pen with a magnetic head I purchased sure works a treat to get all the ball bearings out in one go. As did inserting the axle while dropping the ball bearings into the cup so they can't fall through.

Tandem wheel? I considered 4 cross, but eventually went with 3 for large flange hubs. 4 cross can overlap (or nearly overlap) which can make spoke replacement awkward if you ever have to.
As for multiple goes at lacing that happens, particularly if you are trying to get the hub logo aligned with the valve hole. Best to do that alignment with two spokes in the beginning.

The rear is a 40h Sturmey AW3, and was laced up cross 4 so I just did the same. I could probably have gone with 3. I needed washers under the spoke heads which makes it pretty tight for overlap at the flange but they do just make it. I almost got it laced up first go.

When installing a bolt, first rotate it backwards until it clicks. This positions it properly in the threads. Then wind forwards to install as normal. And use a little grease on the threads.

hi, can you be my new best friend? ive been telling people this for years but i just get blank stares like im from another planet. This tip is especially important with screws that have been from something that is plastic, most plastic parts during the manufacturing process have small holes with no thread, so when the factory worker or robot type thing is putting the screws in place they use screws that have a small groove that runs along the length of the screw which intersects with the screws threads thus making it a "self tapping screw" so if you remove one of these "self tapping " screws then you risk stripping the thread that has been made in the plastic unless it is re-seated correctly by the above mentioned method. this way you know that the start of the screw thread has met the start of the part thread which means clockwise turning will enable the screw to follow the same path that it had originally cut. If one accidentally strips the thread from a part then it is advisable to use another self tapping screw that is of a larger diameter. if you can.
but im a champion bike mechanic because i was having issues with the paint nozzle on a pressure pac can so while i was looking at it i decided to press it see if it was clogged. So basically i just sprayed paint directly into both my eyes. i dropped to my knees screaming to my friend im blind help me ahhh. but he pretended to not hear me , anyway i managed to find my way into the bathroom and wash my face under the tap. Then i contemplated my stupidity, went back out side to resume painting AND DID EXACTLY THE SAME THING AGAIN.

50Nm torque wrenches are crazy expensive I borrowed one from Dad, but I'm not sure I got the right result. Slight rubbing, wonder if I've overtorqued a couple Nm?

And the screwing backwards thing should be taught in schools or something.

On returning to the garage couldn't find the box anywhere, spent fifteen minutes looking for the red box with the new bar tape. Everywhere, including places I was sure I hadn't looked that morning and I knew I had seen the box earlier. Eventually found the plain cardboard coloured box, turns out the red box was was the previous bar tape box, not the current stuff. The new stuff had been in plain sight the whole time, just the wrong colour.
I've gotta tidy up.

I hope you don't handle fire arm's because you just can't wash that mistake away.

Will give this a go tonight once I have some spare hands. Had to admit I was surprised how much the weights were "off" the designated weight. They have a rubber coating, but obviously that's added weight. Something to keep in mind if I ever need to start measuring kilojoules.
TL:DR I am going to calibrate my SRM today
