XC Skiing

 

Christine and I went for our second ski (sort of third for me) on Saturday.  Visibility was low, but the snow was falling, the woods were quiet, and the crowds were light so it was a great day for us.

This is my first year of cross country skiing, but I'm really enjoying it so far.  It reminds me of the types of mountain biking that I like.  Thanks to Nate for letting me borrow his skis when we were out a few weeks ago.  Here is a photo from that day:

Does anyone have a recommendation for their favorite place to go?  So far we've gone to Gold Creek, Hyak, and Easton State Park, all near Snoqualmie Pass.  Easton was our favorite.

Rack Building Basics -- Eyelets

It's been a long time since I've posted a Rack Building Basics entry, but I still have some in the queue.

Today's photo series is about making the eyelets that connect the rack to the fork or frame.  There are a couple of ways of doing this, but this series focuses on doing it with brazed in tabs made of flat stock.  This is similar to how dropouts are made.

The first step is making a slot in the end of the tube for the tab.  I draw the slot and then use a hacksaw and a thin file to make it:

Now we need to cut a piece of flat stock to fit.  I purchased 3' of 1" wide 4130 which is perfect for this purpose.  You only need to make a single cut.  I use the tubing as a gauge to how wide it should be.

The tab is the same width as the tubing:

Brazing just the tab in is probably strong enough.  Note that I filed the end of the tube to slope the tubing towards the tab:

I like to fill the whole end of the tube with a "plug" of brass.  To do this you heat the whole end of the tube and draw the brass around below the tab.  I'd do a few tests first and cut them apart to see how well you do at pulling the brass in.  It is a bit hard to see in this photo, but the whole end of the tube has brass in it.

After removing the flux I do a little work with a round file (12" round which is about 10mm or 3/8" in diameter) to make a nice clean scallop.  The tab has also been bent to match the angle needed for this rack:

A bolt hole is drilled and a file is used to ease off the edges:

A final photo showing where this tab is used on the rack.  It connects the stays to the fork blades:

At the start of the entry I mentioned that there are other alternatives.  A nice and easy one is to braze a piece of tubing perpendicular to the stay and run the bolt through it.  5/16 x 0.035 tubing is a nice fit for an M5 bolt.  This is an especially good idea if you need a spacer to clear part of the fork blade.  In this example the tubing is extended on the inside so that the rack can clear the fork blade even if the fenders aren't installed.  This is from the first rack that I built:

Another option is to simply flatten the tubing in a vise and drill a hole through it.  I think that this looks a little less refined, but it is strong.  Sorry, I don't have any photos of this approach.

Cooper's Hawk in our front yard

We came back from playing in the snow on Wednesday evening and watched a dead pigeon drop out of the sky.  We were a little startled and trying to figure out where it came from when Nate spotted a much larger bird flying to our neighbor's roof.

We all sat inside the living room for 30 minutes and watched the hawk return, monitor the area, and collect his kill.

It's pretty cool having birds of prey in an urban setting!

Based on our tiny Birds of Seattle guide I think this is a Cooper's Hawk.

Tried and Liked 2007 (bike and not bike)

This is a normal internet-BOB (a bicycle mailing list) way of finishing out the year.  I sort of missed it this year (spent too much time on the basement to read the list), so I'll try doing it with the blog.  There is bike and not bike stuff here to make all blog readers happy. 

Not Bike

Le Creuset Omelette Pan -- Le Creuset makes this item really difficult to buy, but it is amazing.  I think that it is impossible to make a bad omelette with it.  The non-stick coating is not teflon and works really well.  The cast iron retains heat really well, so the pan doesn't cool down when you add food to it.  We have one of their frying pans too, and it gets some use, but the omelette pan is used almost every day.  We've owned other omelette pans, but none were as good as this.  We have the smaller size (7 or 8") and it is perfect for 2 egg omelettes.

I've tried to buy these as gifts and they are really hard to find.  They are sometimes in Le Creuset "outlet" stores.  Amazon and most kitchen stores don't carry them.

One Car Family -- Christine and I were a one car, one driver family from moving to Seattle in 1996 until 2002.  Then we bought a new car, I got a driver's license, and we bought a second new car.  We sold our second car in April and don't miss it at all.  Cars are expensive.  They can be handy tools, but we don't need or benefit from two of them.

Fuzzy Logic Rice Cooker -- We rarely use it for rice, but it is amazing for steel cut oats.  One of my favorite foods, but I never liked standing around for 45 minutes stiring it.  The rice cooker makes it better than I do.  The timer means we can have oatmeal ready when we wake up.  I'm not a big kitchen gadget/appliance guy, but this one is great.

Virtual Computers -- I replaced 3 servers with one physical machine.  The new machine has about 30% of the power consumption of the previous 3 machines, is quieter, and takes up less space.  This blog is hosted on a virtual computer.

Smaller Plates -- For years I've wondered why normal dinner plates hold more than one should eat.  I doubt they've always been this big.  I spent a while trying to find smaller ones and finally did.  Denby salad plates are the right size (9", instead of 10 or 11") for a normal sized meal.  Their stonewear is really durable too, we've had their dishes for a year and have chipped anything despite a few drops.  They do make full size plates which we use on special occasions. 

Eating Fish -- I've been lacto-ovo vegetarian since my junior year of high school.  In 2006 I started eating fish to get more food in common with Christine.  My first experiences with fish weren't great, I didn't get the subtle flavor and didn't like the texture.  This year I've come to really appreciate the flavor, enjoy cooking it, and the lean protein is probably good for me.  I am careful with the sources of my fish and worry about sustainability.

Bike 

New Clubs -- I've been riding with point83 and playing Rollo (mini bike polo) this year.  It's fun riding with a younger and less serious crowd.  I'd like to find a group that did some more weekend rides but with a similar mentality.

Metal Fabricating -- It was only last January when I first lit a torch.  In March I bought my own.  Since then I've built about 5 racks and have learned a lot more.  This year I hope to do even more.  Fabricating my own bike parts and modifications is really enjoyable and a nice way to grow the hobby.  This week I got a lathe which will take me to the next step of fabrication.

Porteur Racks -- Building racks has given me the chance to really get used to big front platform racks.  I really like carrying gear up front and have plans to build racks for all of my bikes.  The porteur rack does most of what I used a trailer for and most of what I used panniers for.  It's always there too.  I wish that there were some good production models.

Bicycle Fixation's Knickers -- In 2006 I discovered the Ibex Breakaway Jacket.  A great jacket, but I needed something great for my legs.  The Bicycle Fixation knickers do the job.  I have them in hemp and wool.  I like both, but I like the hemp ones better (unless it is raining hard, then the wool ones are warmer).  The knickers are comfortable on and off the bike, lightweight, look pretty good (for bike clothing...pants would be even better) and work well in a wide range of temps.  Below around 40F I put very light tights underneath.  40F to 65F they are perfect by themselves.

Flat Pedals (no retention) -- about 10 years I've ridden everywhere with clipless pedals.  Since I ride pretty much every day and don't like to change shoes I end up wearing my bike shoes all day.  I didn't even really think that there was another option.  When I went to the Oregon BCA show I didn't want to take two pairs of shoes and knew that I'd be on my feet almost all day.  Flat pedals with good walking shoes made a lot of sense.  So I picked up a pair of the MKS Sneaker pedals and put them on my commuter.  A week later I didn't really miss the clipless pedals much.  Now I have one bike permanently setup with flat pedals and might do another.

Bike Friday Tikit -- It folds small, it rides well, it is reasonably priced for a US made product.  I converted it to a 7sp internal gear hub (which is how they should sell it stock) and it's a great bike.  It's my city rider, my folder, and my travel bike.  I've owned a Bike Friday New World Tourist for years and hardly used it, but the Tikit is getting a lot of miles.

Gifford Pinchot Tour -- Bicycle Touring isn't new for me, but this tour was incredible.  6 months later I still think about it often.  This was the best 5 days that I've spent on a bicycle.
