Tailwind Racing’s Medals are Shiny

Published August 26, 2012

Today was Tailwind Racing’s Stony End of Summer Classic race, and I found myself competing in it. A bit surprisingly I ended up coming in fifth, which got me a medal, shown above. This is the first time I’ve received any medal in a race since some of the Lake Orion High School weeknight races three years back. These are pretty nice medals. There is a sticker on the back which lists the race, class, and place.

This was a really fun race. It was somewhat hot, humid, and a bit dusty, but it was fun. Everyone that I encountered was really courteous and good about passing and being passed, the course was a good length without having an irritating extra short/steep sledding hill at the end. My official time ended up being 1:50:55.399 with laps of 35:49.943, 37:46.442, and 37:19.014. Only once did I almost throw up, but I was able to get that under control and keep going without any problems.

Titus Frame Damage

Published August 26, 2012

While out riding at Highland last weekend I fell over on the Titus. I slightly injured my shin, but also took a few scrapes out of the down tube. This is the first scrape-type damage done to the bike in 2.5 years of riding it (and the only frame damage), so it’s a bit frustrating. Still, I guess it’s not bad after that much riding.

This isn’t anything that should cause any problems (it’s just cosmetic), so that’s at least good.

Addison Oaks MTB Route in OpenStreetMap

Published August 19, 2012

With the upload of OpenStreetMap changeset 12787189 I have finished adding all of the hiking and equestrian trails, intersection markers, and mile markers needed to draw a second generation version of CRAMBA’s Addison Oaks map. This data includes the still-under-construction connector trail which’ll create a new park entrance at Indian Lake and Lake George and provide a safe route to Addison Oaks East and Oakland Township’s Cranberry Lake Park. I also added all of the named routes through the park as found on the official park map, including the specific hiking, biking, and equestrian permissions and restrictions.

If all goes according to plan, the next version of the map will show the actual locations of the C and D trails, shared hike/bike/equestrian (on C only) areas in the west of the park while highlighting the MTB route. The mountain bike route (trail F) frequently crosses these trails and occasionally shares their route, so I want to better illustrate the interplay between them all. This next version will also be based on OpenStreetMap data, which beyond the benefits of being CC BY-SA licensed should make it easier to update and use for future planning.

The only things I have left to add to OpenStreetMap before it’ll be usable for drawing a complete map of the park are a few campground roads and the B loop, a relatively flat and straight hike/bike loop around the campground in the northeast of the park. I’ll probably record that route the next time I’m at the park.

External Intel 320 SSD

Published August 17, 2012

A couple weeks back, the Intel 320 SSD in my iMac failed, leaving the machine unbootable and the drive appearing as an 8MB volume. This drive was replaced with a new 256GB Crucial M4 SSD and the Intel drive was returned for warranty replacement.

Having no immediate need for another SSD but not wanting to have this one laying around I decided to put it in a Macally PHR-S250UAB external enclosure and use it as another piece of fast storage on my Mac. While the installation went well I’m not quite happy with the performance. Despite being connected via FireWire 800 (IEEE 1394b-2002) couple of benchmark tools report only around 80 MB/sec read and 65 MB/sec write while the spinning piece of rust inside the computer reports something like 105 MB/sec read and 107 MB/sec write. It’ll be much lower latency than a spinning disk, but I’m not sure it’ll provide improvement over the internal disk, especially for things I was hoping to do with it like running VMs.

Maybe I’ll give it a try on my work laptop for VMs there, or maybe I’ll see if it’d work out well in Danielle’s Macbook Pro.

The photo above shows the external enclosure with an Intel-provided case sticker applied to the top in place of Macally’s branding. Except for the residual curved blue logo pieces at the end that didn’t fall outside of the cutoff area, I think this worked pretty well. Here is a photo of it all being assembled.

20 Miles before 8:00 AM

Published August 17, 2012

After dropping Danielle off for the her volunteering / crewing at Oakland Mall for the 3-Day and picking up an apple fritter from Donut Castle in Warren I found myself home just a little after 5:00 AM. With a fair bit of time before needing to start work and my feeling sleepy I decided to head out to River Bends for a quick ride.

I returned home just shy of two hours later, having headed up to River Bends via the usual route, through 2.5 laps of the ridable single track (all but the floodplain seasonal loops), then back home via Utica and Whispering Woods Park. The photo above is from a brief jaunt down into the floodplain to see how wet it was. I came across Jeremy’s bridge, which will hopefully be put back some time within the next week.

Since I was starting out in the dark I brought along lights, but they were unnecessary for seeing on pavement, and not needed in the woods by the time I was done with the first lap. This was the first starting-in-darkness ride I’ve done, and as I’m not accustomed to starting off in the dark and needing lights less and less as things progress it was a bit weird. The sun also comes from completely different angles in the morning, making it unexpectedly glaring on some parts of the trail and causing a few stop lights to be difficult to see.

Details of the ride are available here on Strava if you’re interested.

The Circle of Life

Published August 16, 2012

This is the scene on the sidewalk near the front porch: a group of ants eating the remains of a squished cricket full of orange pulp-looking eggs. I wonder if this is the cricket that I’ve been hearing at night when falling asleep.

Nature takes care of its own.

Functional Mukluk

Published July 27, 2012

After the ill-executed (but fun) beach ride a couple weeks ago the Mukluk was in serious need of some work. Specifically, I needed to replace the seized bottom bracket bearings and fix the lower derailleur pulley, and I also wanted to replace the becoming-worn middle chain ring as a bunch of chain suck during the beach ride kept me in the granny gear.

By picking up and assembling some tools (a blind bearing puller and a bearing press assembly) along with the required parts I was able to get all the affected bearings and chainring replaced, and I also swapped out the chain for a standard SRAM PC-991. The Mukluk had come with a KMC Z99 Rust Buster galvanized chain, and while it initially seemed nice I begun wondering if it’s rough surface was contributing to chainring wear.

The replacement chainring is a cheap (~$10) Truvativ ramped 32 tooth steel middle chainring to replace the stock e*thirteen part. While a bit heavier than the alloy model, I suspect that the steel ring will last quite a bit longer than the alloy one did, even when riding in potentially icky conditions. If it doesn’t, at least it was only $10.

A quick ride at River Bends this afternoon ending in rain showed that everything is working nicely, so hopefully everything’s in order for riding the bike as part of a fatbike-only team at tomorrow’s Tree Farm Relay.

Here’s some photos of various steps of this work:

· The e*thirteen bottom bracket after removing the bearings with a blind bearing puller. Conveniently this bottom bracket uses 6806-2RS bearings, the same size as BB30.
· Detail of the 6806-2RS marking on the bearing from the e*thirteen bottom bracket. This one seized up after a ride along the beach and in some fresh lake water.
· KML-brand 6806-2RS bearings to replace the seized bearings in the e*thirteen bottom bracket. These are BB30-size bearings.
· Bearing press made from some eBay-purchased dies, threaded rod, washers, and nuts. Bearings are also shown.
· Home-made bearing press before pushing the BB30 (6806-2RS) bearings into the e*thirteen bottom bracket cups.
· KML 6806-2RS bearings (BB30-size) pressed into e*thirteen bottom bracket cups. This went very smoothly.
· e*thirteen XCX crankset test fit with the newly-installed bearings. Everything aligned nicely.
· Lower SRAM X9 rear derailleur pulley after pressing in a new 626-2RS bearing. This cracked the inner ring of the pully, but appears well seated and spins smoothly so hopefully will remain usable.
· New SRAM PC-991 chain and steel Truvativ Trushift chainring (104 BCD, 32 T) on the e*thirteen crankset.

For reference, here’s the specialized parts that were used:

· e*thirteen Bottom Bracket Bearings: 6806-2RS (Same as BB30)
· SRAM 2011 X9 Lower Derailleur Pulley Bearing: 626-2RS
· BB30 Installation Drivers purchased from eBay seller mtbtools with threaded rod from Mid-States Bolt and Screw.

Résumé Updated for 2012

Published July 20, 2012

Updating one’s résumé can be quite a pain especially if done under duress, so I like to periodically update it so that a fairly fresh copy is readily available. This afternoon I put the finishing touches on the most updated version, one which takes into account some changes at work, stuff that I’ve done with CRAMBA and the MMBA, and a few other newly-acquired skills.

If you’d like to see a copy of my resume it can be found at nuxx.net/resume.
