Thanks again, it has been fun learning about this old bike. I welded the cracked chainstays Saturday and took it to the local LBS to get some headset bearings found.
After it gets back I will just do some touch up paint around the weld and some other worn areas. The bike was originally red, but the orange is a nice patina. For now I'll leave the SA three speed on and find a new front wheel. Rear brakes will stay also. Thinking bottom tube mounted 3 speed shift location.
Not staying will be the chain guard, already ground off the mounting tabs. Seat post, which had to get pounded out after soaking in lube for a day, ditto for the stem. Thinking about keeping the crank if I can find a key bold that matches the original, right now I only have one. Otherwise I can save a lot of weight with a new bottom bracket and crank set up. Pedals have to go one is bent anyway. Front brake and wheel lock will not be reinstalled.
