Sidestand extension

Over the past weekend, I finally took care of one of those jobs that's been nagging me since last Summer. Ever since I upgraded the suspension on my bike, I have been reluctant to use the sidestand much. It was too short, and left the bike sitting at rather a crazy angle.




Not only is this angle tough on the parts, it is tough on my left leg when I try to stand the bike up. So I've been using the centerstand almost exclusively, which has been less than perfectly convenient.

So I pulled out a few tools and got to work. First, I removed the sidestand and marked it up. I scribed a straight line top to bottom (for later alignment) and scribed a circle around it at what I thought was a good location.





Then the irreversible:



Next up, I needed a piece of steel to put in the middle. Since A2 tool steel is what I have on hand, that's what I used. Makes for a very expensive side stand...




That was easy enough with the mini-lathe. I ground chamfers all around the areas to be attached and test-fit them:



Welding time! My welds aren't nearly as pretty as I'd like, nor as free of voids... But I think this will hold. The grinder helps with the look, and the shoulders on the insert should help to keep things seated.



After several alternate passes of grinder and welder, I had something I think was strong enough and decent looking enough to paint. So I primed and painted the thing and had it installed by dinner time.




And now, my bike finally isn't ready to toss itself over when on the stand.

A bit of brake work

On Sunday, I replaced the brake disk and pads on the front end of the bike. Technically my old disk was within specs (4.5 mm minimum thickness) but I was unhappy with how much material would have to come off in order to get it properly smooth. So I bought an EBC MD-650 disk like this one:


Since cyclebrakes.com offers a discount on pads with purchase, I ordered a set to go with the disk. I have a spare set in the garage already, but since the life on those things was kinda short I decided to get the new ones. These are the 'gold' pads, in the highest 'HH' temperature range. They claim to be for superbikes and such. Once they're bedded in we'll see how they do for my application.
