Re: bandsaw problem

Rob
I am one of those who use a chain saw to "rough round" a blank for the
lathe. It is easier and faster than a band saw for larger blanks and for me
that is anything over eight inches. However, for rounding on the band saw
try
(1) use a 3/8" 3 tooth per inch blade and keep it sharp
(2) have a flat for reference and to keep the blank from rolling
(3) use a guide for a good cut. I cut a series of circles out of card board
ranging from 4" to 15". See one used with the chain saw at
http://aroundthewoods.com/firewood.shtml
(4) on the band saw lay the flat from the chain saw cut down on the table
and fasten the circle to the back of the blank with a couple of nails
(5) slowly cut around the circle. The gullets on the blade need time to
clear the wet shavings and dust from the cut.
Let us know if you still have hassles. My 25 year old, 10" (yes 10" not 14")
Rockwell still cuts 5 1/2" thick wet blanks without difficulty. I jsut find
the $80.00 electric chainsaw more appropriate in the shop for such a cut as
I like to heave wet 14" rounds of wood as little as possible. They were
lighter 20 years ago :-)

Rob first off get the right kind of blade to saw GREEN wood, get a 3
or 4 TPI blade that has a extra wide set.
That will cut your blank.
You don't need any circle cutting setup, this is NOT cabinet making,
and also the reason many use a chainsaw to cot blanks to a fairly
round chunk.
Also get the bark off the wood, that's where the sand, grit and gravel
hides, blades do not take kindly to that stuff.
Give it a try and come back if you have more questions, we'll try to
help out.

Leo doesn't understand. A circle jig is an excellent way to ensure even
feed and curve. It is NOT for circle making. Equally as important is to
have a flat surface to reference to the table so the blank can't tilt and
pinch. For that, you can use a scrub and Jack plane. Moreover, if you're
dealing with timber thicker than the 6" capacity of your saw or refining
the blank by tapering off the endgrain, you can use your jig with table
tilt.

Quick search on circle cutting jig should turn you all you need. It's a
place to mount the pin and a way to set its position relative to the front
of the blade
