why does it need a bottom?
This block of wood and I have had several confrontations. It started when I decided to do my 1st recess mount and I cut the recess perfectly in between the range of my smallest jaws and the next size up. Hmmm...
Not willing to pay $60 to Woodcraft for the 35mm jaws that should have cost $37.99 (that's another story that's covered in one of the many Super Nova2 threads), I decided to widen the recess and, since I didn't want to have different plateaus in the recess, I went as deep as I went wide. Each step is a learning experience.
Next came the punky spots and tear out and the new Hunter carbide ringy thing and eventually, I got the piece of mystery grab bag wood sorta looking like a bowl. After that came the need to swap it around and try to figure out what to do with the seriously deep recess. So next came the new Cole Jaws and that led me to discover that the Woodcraft insert for my Nova Lathe and SN2 chuck was not touching the inner face of the chuck which made wobble a fairly reliable outcome. Because the chuck was mated by thread contact only, sometimes it lined up sorta OK and other times (like when I mounted the Cole jaws), it gave off seismic readings.
A call to Tim and coming to grips with the fact that while the other SN2 I had did have the Teknatool insert, I had interfered with the mating surfaces between the insert and the spindle by sticking on one of those, now not so spiffy, nylon washers that make it easy to remove your now wobbling chuck.
Fast forward to this morning and the moment of truth. What to do with the uncooperative bowl that has caused me to buy more turning accessories?
After I mounted the bowl in the now true spinning Cole jaws, I got the idea that maybe a bottom on this bowl was superfluous. Well, the idea actually came to me earlier, while the bowl was chuck mounted in the recess and I decided to take out a bit more of the inner wall of the bowl and ended up with a paper thin bottom.
So here is my bottomless bowl. I might put some sort of insert in it. Maybe I'll thread it.:rolleyes:
