The most elusive Park Tool has surfaced. Bent headtubes, take note.
I've spoken about this tool in the past. I saw it mentioned here once; it was shown in an age-old Park Tools catalog.
Some said it was foolhardy, others said it wouldn't work. Nevertheless, the discussion disappeared into the BF archives, the catalog photo never resurfaced, and an example of one never showed its face since.
Until today.
If you're wondering what this thing is designed to do, this photo should explain it all:
Yes, its a Park headtube straightener, and I'll find out, first-hand, this week, whether it really works (using a 753 Jan Legrand Raleigh Pro as a starting point).

Looking at that I can see no reason why it wouldnt work, looks like a pretty beefy tool though, and you have to wonder what kind of stress it will be unleashing on the frame. how did you come by it?

Looks like it could work, but seems intended to straighten top and downtube rather than headtube.

That certainly is an interesting gadget. Seems like you'd need to use those dent removal things that clamp around the tube as well to completely fix it. Can't wait to see your results.

Ironically enough, I thought about this very tool - for a split second - no less then an hour before I saw it. During Bike Miami, I failed to avoid (though I did "go light" at the last minute) a gigantic pothole with the '61 Paramount. I was nearly convinced that I wouldn't make it through without crunching the front end, though I came out of it with little more then a scare and a dislodged water bottle.

Manual notes that those sleeves are not the right way around, supposedly.

Works well if you're careful...
I was lucky enough to get a few frame tools a while back, and the frame straightener was one of them. More importantly, I have already used it to correct some distortion on an old Peugeot. Have a look at the results and/or read more about this bike and how it turned out.

+1 on that. 753 is not a good candidate to try it on. If you want to send it to me, I can try it on an Ishiwata frame for you.

I remember over on the ratrod bike site, someone mentioning about straightening bent forks. I would be curious, though, for what that tool was actually made. More to the point, it might be intended for hi-ten cruiser frames, and not so useful on any kind of high-end road-bike frame or something.

That's the tool we were talking about to fix my Schwinn New World, so now the question will you rent it to me to try and fix this.

That said though, if I do buy the tool, I'm not willing to ship it out. I wouldn't have anything against doing the frame here though, and considering the tool's size and the weight, the shipping for either would probably be about the same.
Same here.

We would straighten frames this way:
Take a long heavy rod, similar to the one in the Park tool. Insert one end of the rod in the head tube. Insert the other end of the rod between two buildings. (Buildings in NYC are made of concrete or brick, so this serves as a good vise.) Using the frame as a lever, bend the frame against the rod.
Bending isn't really the hard part. It takes force, that's all. The hard part is measuring the alignment.
I did this with my UO-8 frame. I got it mostly straight. It still has a little toe-clip overlap. And it's off to one side, so riding no-hands requires leaning a bit to one side, but that's not very noticeable. It's not noticeable when you hold the handlebars. I rode this bike for years. I retired it about two years ago.
Anyone want this frame? It's a 54 cm. The fork is straight. I'm willing to part it out: frame, fork, crank, headset.
