I gradually spooled off what I thought to be enough tape to make the capstan drive the TT at over 78 rpm.  Then I glued the end down tight.  Checking the speed with a strobe disc, I saw I was off by a few rpm.  So I began to cut off recording tape until I reached 76 rpm (yes, 76, my choice).  Eventually I reached the length that gave me 76 rpm.  Once glued, the TT works great.  That was about 15 years ago.  Still works great!
