Staying Busy + Good Book

Sorry I haven't posted in a good while. While the swine flue did knock me out pretty good for a few weeks, lately I've just been busy catching up with life. I do think (even though this is a bit different for my blog) I should mention a book that I managed to read while sick. Shop Craft as Soulcraft was one of those books (for me) that seemed to put into words, things and ideas that I've been mulling over since people first asked me as a kid "What do you want to do when you grow up?" While not exactly my words, it seemed to express the deeper reasons that I've come to appreciate while deciding to get into bicycle repair and frame building, as opposed to following my Economics degree or Philosophy minor. Not that this book is for everyone, but I feel that there are a handfull of good ideas that even office dwellers can appreciate.

But not to get too caught up in a good book, I have managed to get some more work done on Eddie's frame. I went a bit out of order on this one, and chaced/faced the B.B. shell. That way, I could install some cranks, and check the exact tire/chainring clearance that I've fretted about since first drawing up the blueprint for this frame. There wasn't much room for error when threading the drive side chainstay between the tire and chainring. (only a couple millimeters on each side) So it was a great relief to see everything go from blueprint to finalized function. I've also got both seatstays with custom S-bends fitted and mitered. Just a couple braze-ons, weld the stays, make a seat stay bridge, and some finishing work, and she's getting close to paint.

I Have the Swine Flue!

That's right... after feeling like $#*! for the last week, I finally went to the doc. (hoping it would be another infection, so I could get some anti-biotics, and be done with it) But after some questions, and shoving a q-tip sort of device up my nose - farther than any finger has previously gone - my test came back with H1 N1. Woo hoo! I have no idea where I got it, (I swear I haven't made out with any pigs lately) but now I get to keep taking it easy untill this all goes away. And I'm allready borred out of my mind...

In other news, here's what I was up to with Eddie's frame: Chainstays were mitered, gussets were shaped, and braze-ons were brazed on with the help of some fancy new clamps from Sputnik Tools. (handmade in the U.S.) Let me say how excited I am to be using these! No more fiddling around with bending spokes to hold the braze-ons where I want them, eyeing things up to make sure they're straight and alligned, and heating with one hand and twisting with some pliers with my other hand if they didn't end up straight. Clamp on the tube, slap the braze on under the arm, and it holds it securely, centered, and alligned. I've easily saved 5-10 minutes per brazeon.

After that, drilled all the vent holes quickly and precisely with a fancy new drill press, thanks to my buddy Jason. Then I spent a day sanding, scrubbing, cleaning, welding, soaking, and a little smoothing. Now the main frame is all together, and alignment looking fine. I was worried about the clearance, threading the chainstays between the bigger 2.3" 650b tires and the chainrings. But it came out very nicely. I'm also trying something new with chainstay gussets, instead of a chain stay bridge. My brown bike has no bridge, but I figured the lugged BB was plenty of re-inforcement. With the lugless frame, I wanted to do something to keep that junction strong. And just for kicks, I made a bridge anyhow, and weighed it compaired to the gussets. (not that I'm worried about it, but the gussets ended up saving a few grams) But probably more relevant, they're going to be tough, and cool looking.

Dropping Out

Well Burning at the Bluff was pretty awesome. My team ended up 9th in our class, and 36th overall. This, despite about 7 cold ass creek crossings per lap, and two guys dropping out before their third lap. (if you want a more thorough race report, I refer you to Team Seagal) But the point was to do my three laps, have a good time, and to get excited about getting back into racing. If you know me, or read this blog, you may know this past year has had some setbacks. Breaking my collar bone, surgery, bronchitis/nasal infection, getting married, and going to Germany, are some of the things that broke my momentum and my motivation to train hard for something. But after finally getting back into it (even if I wasn't super fast), I'm totally excited again. And Greg, I owe you one hell of a PBR for spanking my lap times!

Aside from that, I've got the chainstays mated to their respective sliding dropouts at just the right angle for 650b tire clearance. Now a couple miters, some braze-ons, and the main frame will be ready for assembly.

Steel Kickin'

This fork has taken me a bit longer than I was hoping, but I do think it turned out pretty well. There were a couple times that I ended up doing second steps first, and then it would take longer to go back and do the first steps. For example, brazing the whole fork together, before putting the caps on the fork legs. It was harder to match up the exact angles, not to mention hard to get the file in there to make the miters as well as clean it up post braze. None of it has to do with the end result, just the fact that it may have taken me twice as long to get there. But all in all, I think my first go at a segmented fork turned out pretty well.




Aside from that, I'm officially on a three-man team to do "Burnin' at the Bluff" - a twelve hour mountain bike race. This will be my first race in three years, and I'm in no peak performance, but I'm hoping to catch the bug again, and make a serious (for me) solo attempt in '10. I've realized that - for me - having races to train for keep me motivated to ride more, harder, and generally keep me inspired to make these machines with as much attention to their use as to their aesthetic. As much as I love the renaissance of making and refurbishing "old steel frames," I really do believe that there is still room for steel in the cutting edge technology of the bicycle world. With modern steel, as well as modern components, even steel framed bikes can get down into the 15-16lb range.

Not to say that there is no use for other materials. However, with the market pushing those materials to the limits of weight and strength, I think the pendulum must swing a bit back the other way. This past year, it seems that I have seen a good number of bicycle companies making something just able to handle a 130lb rider coasting along on a smooth flat road, and no more. In the ever increasing push for lighter weight, frames must be made stiffer to not deflect enough to break. Aside from sometimes having a "dead" ride quality, that extra stiffness can lead to extra fragility, or brittleness. Many companies are now pushing the "high-mod" carbon as a way to edge out the competitors. Basically, that means making the carbon stiffer, so you can use less of it, thus saving weight. However stiffening up carbon makes it more brittle. And using less of it doesn't help either. Breaking seat masts, seat stays, head tube joints, and even top tubes being crushed when hit with a knee or a chamois covered posterior - after slipping when trying to clip in - all come in as things I've seen in '09.

Don't get me wrong, I think it's awesome someone with enough cash can walk in and buy a bike that doesn't meet the weight limit of the UCI regulations. I have heard a few stories of pro's having to go as far as gluing on weights, or even dropping an extra chain down the seat tube to meet those regulations. But keep in mind why the regulations were invented in the first place. To keep things from being pushed so far that they were no longer reliable, putting the rider at risk. Plus, when putting extra strength and stiffness in certain areas is being marketed as making you go faster, why spend that weight in lead weights, instead of making the frame or other components strong enough to handle the rigors of racing. Again, I'm not totally against, making crazy light bikes. It's pretty cool riding something less than 14 lbs. But if I'm not getting paid a salary, and getting a couple free frames every season, it doesn't make much sense for someone like me to ride one.

One step down...

...many to go!

Got some good work done these last two days. The first miters were done for the front dropouts, as well as mitering the disk brake tab. Then it all went together with some brass. I think I was a little rusty after all the time off, so things went a bit on the lumpy side. But aside from a bit more work smoothing it out, it's tough as nails. (I guess tougher, as nails are usually a pretty mild steel) I will say I'm pretty excited getting this project going. So excited, I ended up waking up at 6:30 and starting into it today, just because I couldn't sleep thinking about how cool this is going to be. It's fun doing something as custom as a 650b specific mountain bike. Also, this will be my first try at a from-scratch, segmented fork design. After doing a little research, a little calculation, I called up my favorite aviation parts/supply company to order some stock 4130 steel tubing. It's pretty cool to see a few lengths of tubing that might have ended up building a piper cub, slowly turn into a rigid mountain bike fork that will have the crap ridden out of it.

(stock tubing... nothing special here)


(...but do a little miter work,)


(...check the angles,)


(...and now it's starting to look familiar.)

Paragon Machine Works

All the bits are in, and while I iron out the last details before getting out the files, let me tell you how excited I am about some small chunks of steel. First off, I am in no way sponsored by, a part of, or even get discounts from: Paragon Machine Works. But what I am, is impressed at the quality and seriousness that is taken to make some of the nicest machined braze-ons, dropouts, and other frame bits available. Not only are they cooler, smarter, stronger, and or lighter, but they're pretty enough that many call this stuff 'frame jewelry.' Competitively priced, they're making the ol' "Made in the U.S.A." tag mean something good again. If only the U.S. car manufacturers were that cool.

The reason I'm talking about it so much now, is that I've used the excuse of ordering one thing from them, to order about $500.00 of stuff from them. The sliding dropouts that helped put them on the map have now expanded to pretty much everything except the main frame tubes. And every bit is given the utmost in design and detail. So I'm happy to say that with the U.S. made True Temper tubing, flux and filler from Henry James, and everything else down to the B.B. shell made from P.M.W. this next project will truly be a "Handmade in the U.S.A." bicycle frame.


And as always, more pictures here.

Sometimes Hard Work Pays Off

Justin's frame is painted, reamed, faced, chased, frame-saved, stickered, packed, and should ship out today. Ok, so I was feeling pretty down on the whole 'hidden binder bolt' lately. It was just too much work, and a real pain in the neck. But now that it's all finished and painted, it does look pretty sweet. Not to say I'll do another one anytime soon, (or ever) but I think it is pretty cool. Thanks for being patient Justin. Hope it's not too stiff.





As always, more pictures here on my Flickr site.
