Early on when he got here he had Rivendell that needed a couple of new tubes. The customer insisted on using the lugs again, Bob milled out the old lugs so they could be used again without being overheated from torching it apart. I had never seen that before, very impressive to me.

He worked for Bilenky for quite awhile before coming to PDX. I don't think there is anything he can't excel at.

Yep, that's what I thought too. Even with my pathetic fab/hacking skills, it all starts with holding the workpiece firmly in place to cut, file, drill, etc.

Lambert w/ lugged frame
Those seat lugs sure are pretty. For custom frame builders this is a place to show what they can do or provide a unique look.
This is a high or wanting to be high production volume frame from Lambert. This is from around 1972 -'73 since it is fully lugged. They went to fillet brazing later.
What I like about this frame is the "upside-down" seat stay, with the thicker part of the tube at the seat lug.
The original paint appears to be a lacquer based on the cracking pattern. I like it. The touch up paint is Rustoleum enamel. Not as elegant.
Production bikes also have interesting seat lugs. The opposite of this frame is a Motobecane,I cannot remember the model, but it had thin seat stays near the seat lug that wrapped around the seat lug. I believe Raleigh and others made frames in this style too, but the Motobecane was so thin that it looked like it was too delicate to ride. It wasn't. Perhaps someone has a picture of one of these.

That's a machined groove. It's actually part of the seat tube.

Naked Schwinn Seat Cluster
This picture is of a 1980 Schwinn Continental. I'm confident that the process hadn't changed at Schwinn in decades, so it is probably the same as a 1960's Continental and other bikes in their line.
Technically, you would be correct to berate me for posting a non-lugged seat cluster, but we like pictures and it does help to put the beauty of low production and custom frames into perspective.
It looks to me like Schwinn had some way to cut the top tube into a "fishmouth" then flare it in order to get enough contact area to braze it to the seat tube. If you look carefully you can see the gold color between the seat tube and the top tube. If I would have known, I would have done a better job of removing the paint at this joint. This is not the prettiest way to attach a top tube to a seat tube, but Schwinn was making bikes in high volume with a lifetime guarantee.
The seat tubes have a ball end. This is almost a Schwinn signature look for their seat tubes whether they end at the seat cluster or the down tube as on cantilever frames. They all had this same end on Chicago made frames. I suspect they took the cut end of the tube and roll-formed it into a ball end.

I've highlighted the section about how the top tube is joined to the seat tube....
Sometimes I forget how specialized the assembly of the humble Varsity was!
