hi, first time poster!
I have recently purchased a pearl drill, Japanese with a swivel holder, and have been attempting to drill my own pearls for design. I have have run into a couple of problems.
1. Some times I try to drill a pearl and it is like trying to drill a rock. If I force it the bit typically breaks. What am I doing wrong?
2. If I am drilling the pearls for a necklace, what size bit should I use?
3. Some times (with the larger pearls), I cannot get the swivel to spin without retracting the bit. I am worried that this may misalign the holes. Is there something I am missing?
