telling me that there should be a mchine that takes a spool of thread underneath so bobbin and thread would run out at the same time. Never seen one in person in exceptioal condition.
So, the issue with these is that the machine when making the loop has to go around the bobbin.
Since a two spool has a BIG bobbin, it need a big loop. this limits the speed that the machine can operate at.
Hard to market.
BTW - My 1863 Grover and Baker (The machine that is my Avatar picture here) uses a spool of thread above and below.
