Haven't tried multiple start threads yet, the Summit has some sort of indexing plate built into the back of the spindle for up to 10 start threads. Been a while since I had the cover open but I think its a plate on the spindle and a pin system to lock the first gear in the drive. Simply index it over to move the start of the next thread.
Free advice is worth exactly what you payed for it.
