Fork out, more sanding

Yesterday, after having given up previously, I was able to remove Ol’ Paint’s fork from the frame. After stripping the frame at the start of this project I had tried hammering on the steerer tube (actually, on a block of wood placed atop the steerer tube) without any luck. I’d decided to let it be, as I was content that the headset bearings were in fine shape, but then I stumbled across this post. The suggestion involving snipping up an old pair of jeans seemed to make sense (on the second read; although I think an old belt would do the trick as well), but then there was the update by the original poster about turning the frame upside-down and hammering the whole thing down so the steerer tube strikes a block of wood, and that sounded worth a try as well.

I gave the latter technique a try and to my surprise, after the first rap on the wooden block, the headset popped right open. It was stunning how little force was required given that I’d hammered on it before to no avail — leverage!

The headset seems to be in fine shape, but I’m still glad I now have the chance to give it a good cleaning and packing with new grease before reassembly.

With that done, I tackled the sanding with renewed enthusiasm. The parts of the frame I’ve already sanded are rusting quite quickly, so I’ll have to hurry up and get the frame ready for painting. In my mind, it’s all clean shiny steel when the prep is done.

But given the time constraints and my skill level, I may now settle for less than perfection. I want to get all the existing paint at least roughed up with sandpaper, if not removed down to the bare metal, before painting. I’m glad to say that my chosen paint is specifically formulated to work on a bare frame or painted, with or without primer.

In addition to getting the main frame tubes this time around, I began working on some of the detail bits. One priority was the inside of the seat tube, where rust had held the seatpost locked in place. I’d gotten a wooden dowel specifically for this purpose, and wrapped the sandpaper around it before taking it to the inner end of the seat tube.

With that done I turned my attention to other detail places, such as the brake bridge between the seat stays. The wooden dowel also came in handy for cleaning up the rear dropouts and the bottom bracket shell. With the latter I just have to take care because it’s threaded for the bottom bracket bearings.

Finally, I spent more time with the fork, particularly the rounded shoulders. The wooden dowel came in handy again with the lower end of the steerer tube, although it was a tight fit here.

After a couple of hours of work on a number of different bits, I felt I’d made good progress despite not having much energy.

I brought the various bits of the headset home with me, and had a go at them today with a brush and some degreaser. They all cleaned up fine, which reinforced my impression that this headset can be reused. I thought I saw a model number on a couple of the spacers (which would help with the specs if I had to replace the unit), but it just turned out to be a fairly generic patent number.
