Problems rounding blanks with Band Saw

OK, need a bit of help here. I've got a bunch of cherry, maple and some apple that is an average of 4 months since being cut. I sealed the ends of the logs I cut to minimize cracking and splitting.
Now that I'm actually getting(making) some time to work on my lathe I want to cut the logs in to bowl blanks and turn them while "semi-green".
The problem I have is that when I go to trim the blanks to round on the band saw it keeps binding/stalling. I'm feeding slow and tried even slower- no success.
I've got a Craftsman 12" bandsaw with an Olson 6 TPI skip tooth 1/4" blade. I know it's not a Jet/Grizzly class machine but for now I was hoping it would at least get me going since it has the capacity to cut the size blanks I can turn on my Jet 1014 lathe.
Do I need a different blade because I'm trying to saw green wood??
Thoughts, suggestions and even admonitions welcomed and appreciated.

For green wood you would do better probably with only 3-4 TPI. A blade designed for green wood clears the waste quicker and binds less.
Highland woodworking has a great woodturners blade. Their catalog is free and has some great info that when I was starting answered a lot of questions.

I'm no expert, but I use a 3/4" blade for rough cutting like that...
Usually 3 TPI, but if I have a 10 TPI blade on, I'll use that...

I use 1/4" blades rarely, and only for much finer cuts.

p

...ever notice how "I'm sorry" and "I apologize" mean the same thing, unless you are at a funeral..?

woodcraft sells blades specifically designed for green wood. I cooked a 4 tpi blade cutting a white oak burl into chunks and the issue was my blade. I take the one designed for green wood or wood that is around 12 -16 inches and it blast right threw them. is your bandsaw 208 0r 120. my rikon at 120 will bog down a bit if i am cutting a big log. i am going to rewire it to 208!

I use a 1/4" blade when I'm in a hurry and it's on my saw. I have a 14" Delta. Blade tension is pretty critical. If you push the cut at all the blade will try to bow and this binds the blade. Try increasing your tension.
That being said I normally use a 1/2" 3 tpi blade. It's much easier to not force the cut.

I cannot tell the difference between skip or raker blades but think raker and hook tooth blades better for cutting bowl blanks.

Might try ” x 3 tpi or 3/8” x 3 tpi Lenox blades they also carry 1/2" blades too.
