Ridable Rack

This will be the last rack posting for a little while, until it is actually complete.

(click for more photos)

I installed the other stay and a backstop last night, cleaned up the flux, and mounted the rack on my bike.  I only used it for a short ride this morning but it seems to work very well.  I was worried that my stays were too far forward and would cause problems with the front wheel hook on the bus rack, but it wasn't an issue.

Remaining work:

  • Install a light mount.  I think I'm going to get a Lumotec Oval and mount it between the stay and the wheel.  It looks like there is enough space.
  • Wire routing for the light.
  • Fender eyelets (so the fender mounts to the rack)

The bike handles nicely with the front bag.  This isn't a surprise since it is a lower trail bike (45mm trail).  There is a small amount of shimmy when riding no hands, but this will probably go away if I drop the tire pressure a little.  I normally ride these tires (28mm Avocet Duros) at 75psi but they are at 90psi right now.

Rack progress

My vacation put a little hold on my rack making, but this week I did get to spend a few hours in the workshop.  The gallery is updated.

 

I'm pretty happy with the progress for a first rack.  I wish I had spent more time when making the bends for the rack top, some of them aren't perfect and it makes the whole thing slightly wonky.  The top has a slight twist in it when viewed from the front, it doesn't all lie in a nice plane.  It'll definately be functional but it might not be pretty.

 

I'm pretty happy with how the mount to the fork crown came out.  It is tricky to get everything to fit when you use a sidepull brake (instead of cantilevers).  I should have left my mock-up brake on for the photos.

The other challenging part has been coming up with fixtures for holding things in place while I braze them.  I built the rack in this order:

  • Make the top
  • Make the fork crown mount
  • Attach the fork crown mount to the top
  • Make and attach the stays to the top
  • Make and attach the backstop to the top

Attaching the fork crown mount to the rack top was tricky.  I did it by mounting a wheel (no tire) into the fork and putting a long and skinny piece of wood onto the wheel (coming off at a tangent).  The end of the wood had a groove which held the front of the rack at the centerline.  I used a ziptie around a spoke and the fork blade to keep the whole thing in compression.  The rear of the rack was held against the mitered fork crown mount using this compression.

How do others do it?

 

 

Oregon Coast Trip

Christine and I spent last week along the Oregon coast.  We had originally planned to go to Jamaica for diving but changed our plans when Christine injured her ears (due to diving with an unknown sinus infection).  They'll heal but the doctor asked her not to fly for a couple of months.

We spent 5 days in Manzanita, OR (about 20 miles south of Cannon Beach and 20 miles north of Tillamook).  The weather was so-so but we mentioned to get out for some good hikes on Wednesday and Thursday.  I also went for a bike ride almost every day.

On Friday we drove out to Bend, OR and spent two days hanging out with our friends Nate and Sam.  Saturday Nate, Christine and I went up to Mt Bachelor for a day of skiing (Christine) and snowboarding (Nate and I). 

Some of the good photos follow.  There are dozens more that you can view.

On Sunday we head out from home to stay in a yurt at Fort Stevens State Park.  I had a lot of fun exploring the old fort.  I think that it is incredible and wonderful that these are left open for people to explore instead of boarded up and closed off from the public view.  My favorite area was Russell Battery which is getting mossy and green and which was completely deserted.

On Tuesday we hiked the Cape Falcon Trail in Oswald West State Park.  This was a great hike and since we were there in the off season we only saw a couple of other hikers.  The hike goes along a bluff out to the end of the cape.  You get great views of the Oswald West beach for the first half of the hike and then wonderful views of the rest of the coastline as you get out to the cape.  The forest had early spring wildflowers (trillium mostly) and was very dense and lush from the rain:

and the view itself:

On Thursday we went to Hug Point just south of Cannon Beach and then to Ecola State Park just north of Cannon Beach.  At Ecola State Park we hiked the somewhat new Clatsop Loop Trail.  This is a 2 1/2 mile trail that climbs up through the forest, takes you to a nice view of a lighthouse, then drops back down closer to the coast, where you get the same view of the lighthouse.  Christine and I were both disappointed in it, the Cape Falcon trail was much more scenic, less crowded, and much more enjoyable. 

Hug Point was a really pretty beach and reminded me of Shi Shi Beach (although much less remote).  It had a waterfall and a lot of interesting rock formations.  Sadly we were there as the tide was coming in and couldn't stay long (you can get trapped on certain parts of the beach).  The tide pools also didn't have very much wildlife at this time of year.

Here is the lighthouse that you see from the Clatsop loop trail:

Finally here are a couple of photos from our ski trip on Saturday.  It was Christine's first time back on skis in about 5 years and she did great.  It was my only snowboarding trip this year and I did okay, but still lack confidence sometimes.

It was a great trip.  We had never been to Bend and hadn't been to the Oregon coast in 9 1/2 years.  I don't think we'll wait that long to return to either area.

Starting on rack building

I finally made the plunge and bought the equipment necessary to braze racks out of steel.  I spent a lot of time asking Alistair, framebuilding members, and random people at NAHBS what I should buy and finally ended up getting a Victor Superrange II.  The torch is a little bigger than ideal, but the price for the whole kit was a lot cheaper than putting together my own kit with good regulators and a smaller airplane torch.  The included regulator was also compatible with propane (I'm using Oxygen/Propane instead of the more common Oxygen/Acetylene).  I also bought a Ridgid 3/8" tubing bender, stocked up on files, and ordered a bunch of tubing from Aircraft Spruce.

The first project is a handlebar bag rack for my Trek road bike.  It has caliper brakes and I'm not crazy about the common designs for racks that would fit. 

Tonight I got home and built the platform:

It's not perfect, but it'll be perfectly functional.  I messed up when measuring the platform and was off by about 1/4" where it the two ends of the outer tubing join each other.  I brazed in a little filler piece of tubing to make it work.  The joint isn't perfectly smooth, but I think it'll be okay after I sand it out.  The perimeter of the rack is made out of 3/8" tubing because that is what works with my bender, but I'm using lighter 5/16" tubing elsewhere.  Click the picture to see more photos.

I'm excited about building some more and finishing up this.  I think my second project will be a good lowrider rack for my Bike Friday, the stock one is terrible.

Lessons learned so far:

  • Measure carefully when making the perimeter for a platform
  • The flux that Henry James sells is much nicer than what I picked up from the local welding store.  I can't wait for my HJ order to arrive.
  • Measure more carefully when trying to make things look balanced.  My middle-stay is slightly off center.

 

Back to back bike shows

Two weekends ago I went to the North American Hand Made Bicycle Show (everyone just called it NAHBS) in San Jose.  It was overwhelming and wonderful.  I met many great people (builders and visitors -- we had a nice lunch on Saturday with a lot of people from the Internet-BOB list). 

I have hundreds of photos here:

This past weekend it was time for the Seattle Bike Expo.  I wasn't super excited about this one, but I did want to stop by and visit Jeff Lyon and see if any other builders showed up.  Jeff and I had a nice conversation and also I ran into Val Kleitz (ex-owner of Bikesmith, my favorite bike shop), Kathleen from Free Range Cycles, and some other folks.  Sadly I didn't get to spend too much time at the show and I had to head back before getting to see all of it.  Photos from the Expo are here:

Finally, I just need to plug this really nice new randonneuring bike that Jeff Lyon built:

68mm of fork offset, 650B, custom racks, nice fenderlines, a beautiful paint job by Keith Anderson, and a nice build.  It really came together nicely.
