I've seen one of those schwinn aluminum frames retrofitted with a seattube collar, but I don't know how well that works. I guess you'd have to trim the top of the tube to get a level surface for the collar. But the original seatposts seem to cost as much as the frames these days if you can even find one.

@herbarium, that's a great video. RJ the Bike Guy is really smart, and I learned a lot from the video.
I saw the drill press and thought I'd never afford one. But I looked for drill presses just now, and it pointed me to this video where a guy reviews a cheap one that he paid $81 for. It turns out it's a good tool and worth having. The price has gone up to $99. I put it in my Amazon cart, but I probably won't buy it soon. I'll just save it for the occasion of need. RJ's video uses a seatpost with an integrated clamp. Those are nicer, but I've always managed fine with straight seatposts and external clamps. I can always get the angle right. The clamps do tend to wear out, but they're easy to replace. And it made the job easier.
I did not use a larger stem to reap the wedge. I used the wedge that came with the long stem. In theory, this means the surface area of contact is smaller than ideal, but it worked. I did not use a protractor to get the angle right. I just eyeballed the angle and used a hacksaw and a file. On the first cut, I got it wrong. I don't remember if I cut a second time or just filed it down or whatever, but with some work, I eventually got the angle right. (I added a $20 digital protractor to my Amazon cart, too, so thanks again, RJ.)
I love his technique for machining down the wedge. It's less error-prone than the technique I used on another project which was to reduce the size of a seatpost shim. My technique was to use even pressure as I pressed and turned the seatpost against my bench grinder wheel. It's also important to turn at an even speed. I measured frequently while filing down. So I compensate for lack of tools with extra care and measurement.
I wasn't sure I would succeed, because the whole thing seemed tricky, but I managed. It's not as hard as I expected, so you can do it, too.

I also subscribed to Wranglerstar's youtube channel, because I can learn a lot from him.

Yeah, the result is just like on a typical modern aluminum frame. I might be able to track down whose bike it was and get a photo, but that will be harder during lockdown.

A pic of this would be great to see, if you can manage to track this down.

ISO a short, recessed nut for a Tektro dual-pivot brake. Sure enough, in reverse of what everyone usually does, I need to convert a nutted front brake that I have here to recessed rear
EDIT: Thank you jethin !

The bearings look like cartridges that have lost their dustcaps. If so, those will be difficult to move.

Plus, why waste a good nutted bolt? I know they sell these aftermarket now, but might as well throw one more into circulation. The recessed bolt folks have had their fun for 35 years, it's time to take back the territory

Difficult to explain easily with text. I know there's a Suntour overhaul on youtube. That's a good place to start. The biggest difference will be the grub screw (aka, stop pin). These Shimano ones often aren't removable, so, upon reassembly, you begin threading the cage spring bolt but wind the spring before finally tightening down the bolt.

- Fork w approx 8” or more steerer, 700c wheels, 26.4 crown. For a beater, so not picky.
- Suntour barcon mounting pod — just the cylindrical expander part and screw.

A friend gifted me some forks recently; I’ll try to check if anything meets your specs.

Which cylindrical part - the screw with the conical head, or the three expanding sleeve sections (need both?)

Well RATS!
My new Cardiff that I got here on BF has broken a metal buckle. Looking for a short 6” brown leather strap to replace it.
Could go toe straps or try replacing the buckle but wanted to see if any here have one to trade for.
Thanks all!

I'm in search of a mid-eighties steel racing frame and fork. Something in the 59-61cm range with a light tube set. Open to anything, but primarily interested in Japanese tube sets and builders. I would also entertain the idea of a newer titanium frame. Thanks!

Are there any good leather crafters in your area? That would be my first choice; but I think think the buckle is designed to fail due to the thin stress point.
