Stem Chart Tool

I've had a few chances recently where I've needed to figure out the right stem to buy for a bicycle.  In the past I've always drawn out the existing stem on graph paper and then marked where I'd like my handlebars to be and used that to figure out what new stem would work.  Here is an example:

In this case I was trying to figure out the right stem for my RB-T.  I had a 9cm stem on there with a 96 degree angle.  I wanted 2-3cm more rise and about 1cm more reach.  So I graphed out the existing stem, then drew a point 2.5cm higher and 1cm farther out and figured out what would work.  It turned out that an 11cm stem with a 17 degree angle worked well.  The line shows the top of the headset, in both cases I used 3cm of spacers.

This works great, but computers can make things easier.  I also wanted to figure out how to generate graphics on the fly from a webpage, so I made a new tool.  Here is the same thing done with that tool:

 

It uses the word "spacers" but you can think "exposed quill" if you are working with quill stems.  The default page shows how one might replace a Technomic style quill stem with one that has a little rise to have less exposed quill:

You can find the tool here:

It shows off my normal terrible design skills, but gets the job done.

Thinking about space and workshops

When we moved to our current house I thought the basement was huge and would be a great place to work.  4 years later and feels crowded and out of control.  For the past 6 months I've been thinking about different solutions to that problem.

My initial thoughts were to build a second building in our backyard.  My original design was a garage because this seemed like it would make the most sense for house resale and I liked the roof top deck:

Christine was understandably upset about me taking over one third of the yard.  The project would also be very expensive, and I wasn't sure that a garage was necessarily the best shape.

Version 2 of this plan was still an outbuilding, but one with a smaller footprint and higher ceilings.  The tall ceilings would give me plenty of storage (hanging bicycles from the ceiling) and the footprint would be large enough for me needs.  It wouldn't be huge, but it would be okay.  That plan looked like this (in cut-away fashion):

Last weekend I made the bad (for me) discovery that the maximum building size without a permit was 120sqft, not 150sqft.  120sqft is really too small to be a good workshop.  I've also been trying to simplify, and I needed to consider that building a new structure wasn't really simplifying.  This week I've been drawing my current basement in Visio to see if I can come up with a better layout.

I started by drawing only the bike part of the basement, but I realized that I needed to consider the whole basement to really make sense of what I have.  Here is what I have now:

My real problem with the current basement isn't the lack of square feet (it is around 450-500sqft), it is with the layout.  I have it split into four major areas, two workshops (bicycles and woodworking), laundry, and storage.  Both of the workshop areas are too small for the individual goals and they can't easily be combined due to the layout of the basement.  You can see that the bike area is tiny, I can hardly turn around if I have a bike setup on a stand.  The bike area needs to be close to the back door for ventilation.

Last night I rotated the storage room by 90 degrees and came up with a much more workable plan:

The key thing here was combining my workshops into a single space.  That space is 15ft x 17ft, plenty big for any of my projects.  There are two posts in the way, but I can't do too much about that.  The storage room is slightly smaller but has about the same amount of shelf space.  My stuff won't clutter up the laundry area.  Bike storage was moved out of the workshop area, reducing clutter there.

I'm excited about this plan.  It's not expensive (especially when compared to building a new structure) and should make the space much more useful.  I'll probably put some of my brazing projects on hold this winter to build out the space this way.

I made a Visio stencil with hanging bicycles and bicycles sitting on the floor for those who want to figure out their workshop space.

Oregon BCA Show

On Saturday morning Alistair and I met at my house and biked down to Seattle Amtrak station.  We were heading to Portland for the Oregon Bicycle Constructor's Association show.  Taking bikes on Amtrak was great, Alistair just rolled his bike into the baggage car and I folded my Tikit it and stuck it in the baggage closet at the end of each car.  Tickets weren't too expensive ($55 round trip per person, $10 for Alistair's bike) and it was much more enjoyable than driving.

Saturday afternoon we went to Strawberry Cycles for a gathering of builders.  I talked to Dave Levy (TiCycles), Sacha White (Vanilla), John (a builder in Ashland), Tony Pereira, Andy Newlands (Strawberry) and many other interesting folks.

Joe Broach and his wife Rachel met up with us a few hours later and the four of us went to a good Arabic restaurant for dinner.  Joe and Rachel very nicely guided us back to the apartment where we were staying (I think we would have been able to find it, but not nearly as quickly) and we spent a couple of hours hanging out with our hosts before heading to bed.

In the morning we had a nice breakfast at The Paradox (a veggie breakfast place) with a few of Alistair's friends, then met up with Joe to ride to the show.

The climb up to the show through Washington Park was great.  I'd love to have a climb like that in Seattle.  Alistair remarked that it was like Interlake only much much longer.  I'd agree.  Oddly (especially for bike centric Portland) we only saw one or two other cyclists heading up there, most people took the MAX (light rail).

We arrived at the show at about 11:30.  It was in a pretty small room and very tightly packed.  The lighting was pretty dim, so I didn't take as many photos as I'd have liked.  Most of the day went by in a blur of talking to interesting folks and looking at great bikes, but here are some of the highlights.

Bike Friday was there showing off some really nicely made Tikit and other bikes as well as a custom tandem.  The bike that got the most interest was a very lightweight Bike Friday (15lbs) built by Rob English, but I was more attracted to the fillet brazed frame made by Eric (one of their brazers).  It has a little front rack, steel Wald fenders, and a cool homemade seatpost.  The tandem was also incredible, it just had a lot of small details and one off pieces.  I've met Bike Friday folks many times, but it is usually the sales force.  It was great to talk to the guys involved in manufacturing the bikes.  I think they have some of the more interesting jobs in the bike world considering how unique the designs are.

Tony Pereira was showing off a few new frames that hadn't been painted yet.  I really liked the 650B Randonneuring bicycle.  It had a great custom twin plate crown, subtle manipulation of the chainstays to fit wide tires, and excellent workmanship.  I look forward to seeing this bike in person once it is built up.

 

Jeff Lyon was showing off a collection of road, cyclocross, and randoneeuring frames.  I really like his front racks, especially the one shown here that was made of 1/4" tubing and chrome plated.  He also has the best headlight mounts out for his front racks.  Jeff is a great guy to talk to, I wish the show was a little less busy so that I could have spent a little more timing hanging out there.

Ahearne always has some interesting bikes.  At this show they had an unpainted bike with a porteur rack, Rohloff hub, and some interesting chainstays.  It was a really stout bike and would be great for dirt road touring.  They also had Joseph Ahearne's personal camping bike complete with a Ti Spork headbadge, a collection of great racks, and a nice fork built for the Surly Pugsley wheels and tires.

The last builder that I'll highlight is "m.a.p. cycles".  Mitch is just starting out but has already built two impressive bikes.  I love the rack on his porteur, I just can't imagine mapping out of all the twists and turns in the rack deck.  He also built a really nice mixte with a Tubus Fly-like (or maybe a modified Tubus Fly) rear rack.

 

I have dozens of additional photos, and they are mostly well tagged.

I don't know if Oregon BCA will become an annual event, but I hope that it does.  I'd like to see it grow to include other NW builders from Washington, Idaho and Montana.  The Oregon/NW focus (compared to the international focus of NAHBS) seemed to allow a wider breadth of experience levels and exposed me to smaller builders that I'd never heard of.

A nice November weekend

November is normally very wet in Seattle, but this weekend was dry and unseasonably warm (mid-50s).  I spent much of it outside.

Saturday morning Christine and I started finishing the new doors that go out to the bedroom deck.  This is a project that we put off for years and it is great to finally have new doors that open and close and that we can see through (the old doors had cracked seals in almost all of the windows).  To protect them properly we had to seal the wood with polyurethane.

Saturday afternoon I took off on my bike for some errands.  My first stop was Free Range Cycles where I saw Kathleen's nice Jeff Lyon city bike and picked up a jewelry like but inexpensive Origin-8 stem.  Her bike looked great, I was at the Seattle Bike Expo when he delivered the frame to her and it was great to see it all put together.  I liked his headlight mount and thought Kathleen's use of an old purse as a saddlebag was cool too.  I was also really happy with the bargain that is an Origin-8 stem, no $30 stem should look this nice.  They come in a variety of lengths and angles and I expect that I'll use them again.

After Free Range I headed over to Alistair's house where we nice conversations (as always) about bikes and other matters.  On my way I stopped at the View Ridge PCC and discovered that they now carry Ten Spoon Winery from Missoula, MT.  I met the owners of the winery last year at my friend David's wedding, he served their wine and I went over to the winery to buy it for him.  The cherry wine is dry (not sweet like most non-grape wines) and was really complex, I look forward to opening this bottle.

 

(I love this photo because we only see bikes on the road...the cars are on the sidelines)

This morning I woke up nice and early and met up with about 20 members of point83 for a breakfast ride.  We met at Top Pot Doughnuts, then rode downtown and across I90 to Mercer Island.  We spent a long time there in "Waffle Park" enjoying real and fake bacon and some nice beverages before riding back to Capital Hill for another breakfast.  I tore off before the final breakfast and rode back to the U District to meet Christine for breakfast at one of our local places.

After my third breakfast of the day I went over to the Bike Shack to hang out and work on the RB-T.  It got some shiny new stainless fenders and I checked out Lee's huge Pugsley wheels and helped some folks.  The Bike Shack is a fun place and I think I'll try to swing by more frequently.  I left them my old SKS fenders and picked up some MKS Sneaker Pedals to try out.

This evening Christine and I walked down to the Neptune (movie theater) to see Into the Wild.  I read this book non-stop when I first picked it up, it is a very consuming story.  The movie was similar.  It's interesting that I remembered all of the details the Alaskan part of Alexander Supertramp's journey, but had forgetten the two years that led up to it.  I'll have to read the book again.  Walking down to the Neptune and back was refreshing too, I always forget about how walkable our neighborhood is.  I'm quick to jump on the bike when I'm solo and probably too quick to jump in the car when I'm with Christine.

I wish all weekends could be this nice.  Got stuff done, had fun with friends, and got in a few miles on the bike.

Bridgestone RB-T back on the road

Two years ago my Bridgestone RB-T was my daily commuter.  I took it apart (needed the parts for other bikes) when I got the Kogswell P/R.  I loved the RB-T though, it was one of my best riding bikes. 

 

Two months ago John Speare offered me a low trail (high rake) steel fork for the RB-T.  I jumped on it, pulled the frame out of storage, added a few more of my own brazeons and then sent the frame, fork, and one of my racks off to powder coating.  They came back on Tuesday and I finished assembling the bike last night.

It's great.  Really really great.  Like meeting up with an old friend who you haven't seen in a long time. 

Typical Alex build -- Nitto Noodle bars, wide range double drivetrain, canti brakes, fenders, front rack.  Some details will change (rear tire, stem, headlight), but the photo gives you the idea.
