The dream has always (in the past few years or so), been to build a bike, and ride the Argus (or cycle tour, or hatever you want to call it) on said bicycle. An achievable dream I reckon (done the "race" a couple times, no record breaking mind you).
What first stopped me was the fact that bicycle tubes are hard to come by, and not particularly cheap. So I left it a while. My workshop is pretty comprehensive at the moment, and I eventually decided I may as well try with mild steel, the stuff that's readily available and comparatively cheap, and only half as strong as 4130 (+_250 mpa vs +_450 mpa yield strength, which i barely understand).
I don't yet have oxy/acetylene for brazing (it's high on the list of things I want to invest in), but I have a good tig welding machine and enough skill with it to keep welds together. I found some geometry online for a commuter/street bike (it was a surly something or other, rest assured that geometry is VERY different to the bike that I made). I had a rough plan, I decided there was nothing to lose and dived right into it.
A few weeks later this came out, my first bike. Many many lessons on measure twice cut once, many lessons on draw it 1:1 (I never did this. But watched enough paul brodie videos to know I was stupid not to). Greatly improved my welding from the start of the project. After first making the frame there were some improvments needed: Replaced the bb shell because it was too thin and warped, replaced the head tube because it was too small for headset cups, then replaced the downtube because the head angle was waaaaay off (thanks to WCW guys for some pointers on that one). Then rode it once or twice. And replaced the fork because geometry again. Then a lot of faffing with tyre clearance because I liked the chunky 700x42c tyres. Anyways. All in all a rodeo.
Components were sourced almost ad cheap as possible because budget. These are the components for those interested:
-Easton rims (raided from jewbacca a few years back)
-fsa (gossamer?) Cranks from classifieds, probably richiespares
-second hand disc hubs (no name i could see) from WCW, New spokes and nips from WCW
-600mm straight bars were lying around
-no name aliexpress mech disc brakes (they're not very good)
-no name aliexpress brakes, which broke in shipping so made new levers for them
-made the stem, cassette spacers, fork racers, top cap, seat clamp (top of the seat clamp was from a bontrager seatpost from wcw)
-Chain was leftover bits from different chains from bike shop days.
-seat was something on which the leather had all fallen off, just a plastic saddle with bent rails, had to add foam and leather.
-skewers are m5 all thread with dome nuts and washers (I will upgrade this at some point, it's already frustrating)
-I had one specialized sawtooth 700x42c lying around in my shop (don't know where I got it from, it's been there for years). Bought a second one to match (this was the biggest expense on the actually bike).
-pedals were another "lying around for years" piece that I found in the box at home.
-specialized grips from Solomons cycles because they were cheap (and matched the tan sidewalls)
-headset was from the "old trash headsets" box at WCW (thanks again nils)
-eccentric bb was me, bearings from silkuni because bb30 standard is one of the only bicycles standards that's also industry standard (6806 bearings).
Final notes on the +-20km I've ridden this bike so far: it is big (I'm pretty tall, like 1.93m), it's waaay too high off the ground, (you've probably heard of bb drop, but what about bb rise?), feels like I'm leaning over the front end a bit too much, it's not very stable because of the high centre of gravity and steep headtube (I cannot ride my bike with no handlebars. Yet). I am unsure of whether this is a wise decision on which to ride the cycle tour, the jury is still out on that. It's heavy.
If you read all of that, thanks for your time, please ask me questions. I'm relatively excited about this because it worked and I am sure I will be making more bikes in the near future (still sticking with mild steel for now, weight is not something I've ever cared about much). I have many many notes on improvements, ideas for next time etc etc. But will fully appreciate any and all ideas should people have them.
Finally some photos. I'm sure there are more should there be interest.
