Tuned this up for a kid today. I tried to test ride it. I made it about 100 feet and had to walk it back. Something was bizarrely wrong. If felt like my leg stopped working or my hip was going to dislocate. Turns out the crank is not 180, more like 170/190 degrees. This why our shop policy...

This guy could show anyone about welding chains. A former volunteer at the local bike coop. I have a few of his simple works. I mounted some on board just using screws or fine wires. https://chainbreakerwelding.com/ Plenty of bike chain frames on the www to copy...

Just reread you post. The Schwinn "Heavy Duti" came with thicker spokes. The hubs had larger spoke holes, the rims had larger nipple holes. A regular size spoke can pull right through the hd size holes. Schwinn has different part numbers for the hd rims. I don't have a .105 or .120 die for...

There have been 2 main tools on the market in the past 50 years for rolling spoke threads. Hozan hand crank model. Different size rollers for different diameters of spokes. Run about $150 to $200 these days. I have one and it's rather tedious to do a whole wheel of spokes. I mostly use it...

Columbia build, probably sold under another name since the serial numbers don't match Columbia branded bikes. They used the wishbone stays design and the dropouts look like typical Columbia joinery. Columbia made some of the US Army bikes during WW2 intended for use at bases and delivering...

On a friends Gios Torino race bike.

Oops, yes. Hiawatha vs Hawthorne. Same serial numbers on both. I have a 1950 but it's missing the head badge. The sprocket has a different pattern on the two names.

After the test ride.. Installed the rear wheel reflector. Changed the 18t cog to a 19t. It seemed a touch over geared. 38 x 19 now. Put knobs back on. 27.56 pounds now. I'd rather use the Schwinn branded Kenda Komfort look-alike tires on another build. Those are one of my favorite...

Hawthorne was Gamble's department store brand name. Many of the Hawthornes were made by Cleveland Welding company, later AMF. (Yeah, the same AMF that once owned Harley Davidson and ruled the bowling alleys). In 1947, they started adding more letters that are often hidden under the paint...

Out for a test ride.

Suggestions for future build offs: "Grocery Getter" build off. Must be able to carry a 12 pack (or more.) Racks, baskets, boxes, etc. Final photo in front of your local food store. Schwinn Varsity build off. One of the most sold models of bikes in the later 20th century. Plenty around...

You might have sucked a ball bearing in when applying grease to a hub. Try a spoke to clear the nozzle. Visited 4 stores today, my local auto stores are only carrying grease in 12 oz tubes for grease guns. At least I can see what the grease looks and feels like. It's not sealed up like some...

Picked up 5 bikes late last night from a local college facilities manager. Abandoned on campus. best of the bunch is a 1984/1985 Raleigh Wyoming mixte 10 speed with flat bars. Others: Mongoose Spectra bso, Schwinn Mirada (pacific version), Giant Boulder SE, Huffy Cranbrook. Hum, all but the...

Before they finished the bridge, the arches turned in to skateboard ramps. Splat. They fenced it off for a couple years until they added the planters. The city skate park is just a few hundred yards upstream. IMO, add some yellow paint and you get the "Golden Arches". Want fries with that...

Sprocket paint order: white primer poppy pink paint pink glitter (clear with the glitter in it) extra layer of clear. The suggestion of using the glitter on matching paint is good. The glitter works best on larger surfaces. Bike tubes/rims are too narrow. The The spray pattern is so...

Haro Vector VO Bob Haro was the first to build freestyle bmx bikes. The V shape in the top tube was a signature design in the bmx bikes that got carried over to the mountain bikes. The tires are pretty awful Specialized Nimbus Flak Jacket. heavy and slow. I rode it up Mt Trashmore. Local...

Not the movie. About 12 years ago our local bike coop got a 25 pound bag of used grease. The local printer (large scale) routinely changed out the grease in their big printing press that was used for countless newspapers. It was great stuff. No signs of any contamination. We ran out a couple...

The pink paint dries slow. Still tacky after several hours. And it's very dry, warm and windy here. I tried some of the pink glitter on the poppy pink enamel on the sprocket and that looks better. The sparkle spray is 2 parts. The clear is like normal spray paint in width but the sparkle...
