When I rode (road) tubs our mechanic (who had also spannered for Roger Hammond) insisted on a meticulous process of glue/tape/glue, done over a couple of days, with epic amounts of tweaking and fiddling to get it just right.
I rode them, and within 100 miles or so both had ‘rotated’ slightly so the base tape was significantly more prominent on one side (maybe 2-3mm) or so. They settled down after that, but it didn’t do much for my confidence that the tyres weren’t going to roll off the first time I threw them into a corner.
When I replaced them I just did a layer of glue, left it an hour (IIRC – as per the instructions on the Conti tin) and they seemed fine.
