I needed a more dependable grocery-getter and taking a cue from @One-eyed Sailor, I am throwing mostly cheap/used parts on this 1957 Schwinn step thru frame that I feel is too nice to chop up. It will be mostly pics with only a little explanation for some of the steps or if someone asks for something in particular. GIGI - grab it (bike) and go get it (stuff).......

I don't know the model, probably doesn't matter. 5 speed with f/r hand brakes. Not sure what tabs(?) would have been welded underneath the top tube. This was going to be an easy straightforward build but the paint was worse than I realized. Getting stripped for paint. The blue under the head badge was beautiful. 20231217_155036.jpg 20231209_142425.jpg20231209_142441.jpg20231217_155111.jpg
 
That's a Schwinn frame, but not Chicago made, it's mid 80's or later.

Still good for a build!

Interesting, I ran the frame numbers 4265904 at the Schwinn link and it came back Aug 1957 or perhaps I miss read. Like you said, it doesn't matter, its a good enough foundation to start with. Thanx @Wildcat

@Wildcat another thing that supports your 80s frame mfg date is the fat fork. I think it was released in the the earl to mid-1980s ?

That straight leg fork is mega cool. I would be glad to use that on a klunker or MX style cruiser. Nice piece

Thanx, I actually have 2 of them and I am going to try some funky fab front fork finessing for the future (next) ORBO fiasco. Ya follow??? :)
 
It was most likely made by Giant. I have a fork which is very similar from a Taiwanese built 26” bmx.
I took a quick look on the Cabe. seems Fu Pao was hired to make cranks after Ashtabula or Wald or whoever folded around the 80s.

from looking at bikehistory.org catalogs, the Cruisers I have: multi speed, Sky Blue color, and fat straight blade fork dates it to '83 maybe an '84 which falls into Wildcat's thinking......its all good.........
 
I scavenged a piece of steel from an old treadmill, or whatever, and it turned out to be 16GA hardened steel. It took about 1 minute to burn up my Lennox hole saw, about 2 minutes after welding short sections of fine toothed bandsaw blade to the hole saw (running a slow 440rpm), and my buddies plasma cutter had a broken air supply hose which prevented cutting thru it. :headbang:
I managed finishing up with the "wheel of death" and a hand held grinding stone to make the holes mostly round.
Hopefully paint tomorrow.....

A little bit of paint makes those poorly cut holes look a bit better. The silver is metallic and the red is the same duplicolor metal spec as the frame. My camera/fone is not doing the flake justice. Ill try a closer pic later in some brighter sunlite (it pops!)........

A little bit of internal seat tube sanding (actually a LOT of sanding w/ 50 grit). I greased the post prior to inserting and driving it to the bottom. I am happy with the amount that will rise above the top tube. That will leave plenty of space for a seat post.
