Cutting logs
 

We were cutting a 10 dia. log in 4" slices for bowls on a band saw.
Worked great until the last cut. i.e. grip wasn't quite the same being
close to the 1 1/2" blade is a bit intimidating. The wood spun and the
blade is bend, thankfully no one was injured. Now it's time to do it
the safe way. Does anyone have a jig to handle this type of sawing AND
a jig for resawing.

From the sound of it, you were cutting into the bark side and the log
rolled. If so, all you need is an L shaped jig. Clamp the log to the jig.
Cut. Move the log and reclamp. cut ... What you Must prevent is any rolling
motion of the log. It is almost impossible to do this by hand.

For resawing, google "resaw technique". Lots of helpful articles out there.

As Lobby said, it sounds like you were cutting from the bark to the center
of the log so as to turn end grain bowls. What you need is something to
prevent the log from rolling. I use a c clamp that rests the arm on the band
saw table and prevents rolling. For a 10" diameter log I think a bar clamp
might be more appropriate.

Sounds like crosscutting rather than ripping. No matter. Answer's the
same.

1) Use the chainsaw, you don't need precision here, so why heft and huff.

2) If you insist on ruining your driveby gloat of a humongous bandsaw to cut
through sand-loaded bark (clean it), get a flat spot to rest the log on on.
Can be as simple as a V block or two parallel 1x1s screwed to the main.
Careful of the screw placement, of course.

3) Full-footprint jig for crosscutting features the blocks attached to
something guided by a bar in the miter gage groove or edge. Bungee will
help keep your hand away.

For ripping operations, numbers one and two are still good. The preferred
jig featured dogs like the commercial outfits and a sled that rides the
miter groove. Commercial jobs and pictures at Woodcraft, make yours
similar. Mine had pipe clamps instead of pinch dogs. Of course back then
I had it attached to a 24" three horse Powermatic - I can gloat too - which,
unfortunately was not mine.
