Got the bottom bracket off the Lenton, cleaned it up and bagged it, so now on to the headset. Which is rusted tight. So I hit the threads with some PB Blaster, let it sit for twenty minutes or so, and try again. Still stuck tight.
Obviously the problem is that headsets insist on turning when you put a wrench on the nut. Given the bike's age and provenience (aka, it's not a cheap bike boom wretch destined for the fix and flip), I need to find a way of putting some serious pressure on the threads while putting no pressure at all on the fork blades.
I'm almost embarrassed to admit that the idea didn't hit me until I'd cracked the second beer of the evening:
Yeah, a chunk a 2x4 and one 14"-20 x 3" bolt, nut and washer. I laid the frame down, fitted the board underneath until it was rubbing against the crown race. Put the bolt through the brake caliper holes and tapped it to dent the board. Drilled thru at the dent. Slipped the bolt back in, dropped the fork on top and bolted it together:
If this hadn't worked tonight, I was prepared to drop by Sears tomorrow and pick up a 1-5/8" socket to use with my 1/2" breaker bar; but the combination of the PB Blaster and my old Model A wrench managed to break it loose. And yeah, you don't want to center the bolt on the board. I'd prefer to have the maximum amount of board possible to turn against.
Now, a question for the group: In the second picture, you can see bits of the old silver-backed reflector tape on the head tube. It's also in a couple of other places. Does anyone have a suggestion of how to remove the stuff WITHOUT damaging the paint. I'd really like to get rid of it, but if it means damaging the paint, I'm prepared to live with it.
