Hello turners!

I'm pretty new to turning and just got my hands on a whole lot of green jacaranda. I'd like to use it to advance my turning skill.

Wondering though how to best cut turning blanks from it without destroying my carbide bandsaw blade? Do you all have any recommendations for this? Is there a best way to clean the gummed up residue from the green wood? Should I have a spare old blade for this kind of thing?

Any insights for this would be greatly appreciated.

Thanks.
