One rite of passage I never did pass was repairing sewups. Removing base tape, cutting stitches, replacing or patching the tube, restitching, regluing base tape. The couple of times I tried I wound up with bulges in the tire that looked like inoperable tumors. So for 30 years, I'v either tossed punctured tubulars or if they are really good one, sent to a company that repairs them.
As to stretching tubulars, I never did understand why the manufacturers didn't just make them larger. Today it would probably be a legal liability thing, to guard against being sued if a tire rolled off the rim, but 40 years ago, tubulars already required stretching. Maybe it is just easier to make them too tight and let the buyer figure out how much to stretch them.

I'm in on the new thread. 20 years ago and my first attempt at gluing sew ups! Nobody told me (or I wasn't listening) about pre stretching, gluing and letting it dry, or at least get tacky,etc... . Thank god I didn't ride those, too much glue EVERYWHERE anyway. I'll bet that carpet still has red Clement glue in it.
