THE CANNON

January 25th, 2008

I just finished a bike for Providence luminary Carrie Cannon. It’s a commuter single speed, and in addition to being lovely in general, it’s a good example of a melange (if you will) of construction techniques.

So what we have here is a frame with a welded front triangle, lugged fork and BB shell, and capped seat stays. There’s a lot going on at the top of the seat tube so let’s take a closer look, shall we?

OK, so as you can see the top tube is TIG welded to the seat tube. To make this super strong, we use an externally butted Dedacciai seat tube – it takes a standard 27.2mm seat post, but the wall thickness increases to 1.1mm at the top of the tube for a stronger weld. Also this makes it strong enough that we can sculpt a nice point into it. That point along with the old-school capped seat stays give it a very classic look, especially when combined with the lugged BB shell:

Also there you can see the mount for a rear fender.

Carrie’s deciding on parts, I’ll post some more pictures of the complete bike hopefully next week.

Also I promised to write about stripping paint with invisible rays! and I didn’t lie! check this out:

Garrett, our erstwhile partner and espresso machine tech, made this for stripping paint. It’s an infrared heating element with a handle; for home use the idea is that it doesn’t get so hot as to vaporize the lead in old house paint. But it works great on bikes too. It gets the top coats soft enough to easily scrape, and from there we can abrasive-blast down to bare metal. It’s much nicer than nasty chemical strippers and you don’t have to worry about any of the stripper lingering on the frame. So if you send in your bike for a repaint this is the sort of high tech, kid glove treatment it’s in for.

    Oh man, that is gorgeous! Makes me want to ghost ride my On One off a bridge and have you build me one… “No really honey, the bike just leapt off the road and, you see, I need a new one”. Be sure to post some shots of the completed bike!

    Dude!! WTF. You call that a “nice” point on the seat tube? It’s a WMD for sure!
    Ouch.

    Looks like hot chocolate… you know… hot.

    […] know what you’re thinking. Why the add-on seat color? Why not a fancy point like on Carrie’s? Well, I’ll tell you. This bike will often be demounted, and packed into a box with the seat […]
