Just recently I scored a project Triumph! So excited. My first bike, too many years ago, was a Triumph Bonneville. It was a trial. Always breaking down, reliably unreliable but I loved that bike and have lamented selling it since the day I let it go.
My new project is a 2005 Daytona 955i. A great bike with only 5000 miles on the clock. It's in need of a lot of love but mechanically whole. It'll be a great project that'll change the shape and goals of my VFR.

I laid hands on a project VFR700 about a year ago. It wasn't and still isn't quite all there but it's mechanically sound and the obvious issues at this point are cosmetic.
These iconic V4s were great bikes in the late 80s, the 700 winning bike of the year in spite of being 50cc's smaller than its Canadian and European cousins. Even pushing 80K miles mine has plenty of snap in the throttle.
OEM fairings are both rare and costly for these machines with new manufacture after market fairings being affordable but still on the costly side. As irony would have it fairings for the venerable race version, the much sought after RC30, are not only readily available but fall in the inexspensive cataegory.
With effort it's possible to turn something like my VFR into something like Geof Infield's VFR.
I've already done some small things, making mechanical repairs, changing mirrors, and updating turn signals. It'll be no simple task but I'm looking forward to putting some new life in this old machine. A V4 just has soul, a sound and feel inline engines don't have and grace at higher RPMs where V-twins rattle things apart.

In the forges of my youth we used mainly straight or ball peens as well as larger sledges. When I lived in Japan I saw some used in the shops I visited but again the majority of hammers were straight, ball and sledge. A recent visit to James Austin's forge in Oakland got my head wrapping back around iron, coupled with a move to East Bay it was kind of a mental homecoming.
It could use some help, cleaning up anyway but in spite of looking rough can be used as is. There are no clear brand markings but there are what appear to be letters, "XhB" or maybe "XRB" on one side of the head.
This type of hammer could very likely have been used to make and maintain crosscut saws of the type introduced into the Michigan logging industry in the 1870's and later and I'd say that's the likely history of this one, especially considering it was found in a log house.
It's future will be as part of my forge tooling. Someone put a lot of time and effort into making it and clearly valued it enough to mark it so it would find its way back to them if lost. The least I can do is put it back to work.

Since these photos were taken its been through a couple evolutions including an upgrade to a modern stem. That will require an upgrade to different shifters and I finally found a celeste saddle for it.
The first image is my complete(almost) Sequoia, the second is of a stock bike from the Specialized website. As sold, the Sequoia had a clunky adjustable stem, a heavy shock absorber seatpost and a funky comfort saddle. It also had an OK gruppo and a light, rigid frame with a nice carbon fork. In short, it didn't look like much at first but, by not ignoring what it could be, I was able to build a nice bike. It's also not too far off from the Sequoia Pro that sold for about double the price of the Sport model. Even got the bar tape looking decent this time!
...of course now that it's built the way I want, works well and looks decent, much like my CAAD8, I'm left questioning whether to risk it locked in a rack.

The latest adoptee in my stable of Frankenbikes is a truly fantastic project. In its current incarnation probably one of the nicest bikes bikes I've ever owned. Built for racing, it's not a great city bike and it's too light for touring but it's a dream to ride.
It mostly took some fussy adjusting and measuring to figure out if it could be done and then a lot of head scratching and wrenching in Italian. I visited all of my usual bike guys and a few more to get help yanking the very stuck Campy Record seatpost out and learn a few critical details about drive trains. For the most part it needed cable adjustments that it would have needed regardless of the cassette. The bike had been sitting a long time and I suspect was formerly fitted with ZIPP wheels and a Campy cassette. It was dusty, dried out and neglected but came right back with a small amount of TLC. The end result is well worth the effort.

|All the files you need|
|Double ended tools ready for final shaping|
The basic process is to cut half circles out of the bristles at the ends and then shape them into hooks as shown side by side in the third image. This should be easy enough to logic out. Use the round files for making round cuts and flat files to shape the hooks
Noteworthy points might be that my best hooks are almost all cut at about forty five degrees if you draw a line from the base of the arch to the end of the hook. You will almost certainly want to cut the inside of the arch before shaping the outside and then remove a lot of material from the shaft leading up to your tool end. The bristles are stiff and you want as little in your way inside the keyway as possible. Polishing is optional but if your raw material is particularly rusted or corroded but it doesn't take much and the tools do clean up a bit with use.
|Different stages of completion of a saw tooth rake|
There are innumerable YouTube videos showing basic attack methods. Fewer deal with tool fabrication. My thought is that tool manufacture is at least as important as the skills one needs for using them. Given the ease of acquisition of bristles and the quality of the metal I focus on making my tools as shown.
Other materials commonly available are windshield wiper blade springs, good but too soft for my liking. That means easy to shape but they wear out much faster and bend easier when you don't wan them to. So, I have and do use these springs but they aren't my preferred stock. A similar common material with potential is bra under wire strips. There are certainly plenty of bras but not so many sitting around waiting to be robbed of the wires. These are also somewhat softer metal and not to my liking.
I'll leave it at that. A couple very basic tools you can get about anywhere and street sweeper bristles you can also get about anywhere and keep a few on hand for later or just find when you need one.
So go out and make a hook and I'll get to work on the next installment, how to make a tension wrench.
