I wish he'd taken a pic of the stub left in the frame, which is like a bunch of sharpened knives pointing at your crotch... And one more ("why not?)

That booklet doesn't say hydrogen embrittlement is the reason. They do say to "stove" (bake) the frame after chroming to eliminate any problems, which is the standard advice for hydrogen embrittlement -- heating drives the hydrogen out. The specific reasons they state for not chroming are the...

Reynolds used to say "no chrome" on 753, some tech mumbojumbo as to why, dunno if it's real.

Good guy to know!

Yep that sounds like a good idea. Be sure to keep us updated. Will the FB share in-process pics? Personally, I love that sh... uh stuff, though it might bore some people. As detailed as possible, if you ask me.

Just seeing this thread for the first time. @Canuk are you still thinking of DIY? That's audacious — you could use it for Audax! I'm certified in 753 but I only made two frames with it, made a similar number in 531SL which is almost as thin. Ironically I wasn't certified yet when I made the...

Yes, 5-vis rings have been strong enough for countless Clydesdales on MTBs, not to mention tandems. I used to compete in Observed Trials, and would bash my TA 5-vis rings on rocks and logs pretty often, usually only bent one or a few teeth, which I could straighten on the spot with a 4" long...

The holes were punched not drilled. Some say the very first ones were drilled, but this is hard to pin down because there were so many that were drilled aftermarket. You can tell they're punched because the punching was done before the flat metal was bent, so the holes are distorted. Fun...

'54 ASC hub. Take a look at the waxed paper that it came wrapped in, mostly perished now.

Green anodized Airlites. They came in other colors of course, but it seems the green ones are rare. Wingnuts are Gripfast.

Wedge-Lock leaflet. Be sure to look at the cartoon near the bottom, p.4. And check out their advertising claims, here are a few of my favorites: * Pure racing stuff — not for "Promenade Percies" or "coffee-bar cowboys" [ hey I'm offended, I'm a proud coffee-bar cowboy!! ] * real AD 2001...

The "other" Wedge-Lock cranks — steel, cottered, arms are tubular, brazed to the pieces at the BB spindle end and the pedal thread end.

Did he ever build a bicycle? As in rideable? I only saw his "bike-shaped object", a mock-up of what he was proposing to build. It was not rideable and weighed something like 40 kg (from very foggy memory) because the parts that were intended to be CNC-machined hollow were just solid metal on...

I only scanned a few of them myself. The rest were digital files sent to me by others. This was back in an era before you could get tons of online storage for free or cheap. I had a little hobby website, that I didn't think anyone would look at, I just wanted to see what it took to make a...

That type would work if you filed the hole in the etrier to match the square on the bolt. That's do-able if you're good with files. The etrier is soft aluminum, so filing the hole to square won't take long. Those bolts usually aren't very strong though. I'd want a heat-treated bolt there.
