Nice work.
Most saws that I have used do like that thick of stack cutting.
I occasionally cut 1-1/2 inch oak and it does work the saw. Need to change blades more often or they cut bevels when you do not want them.
Scrollsawing is cheaper than golf, drinking, gambling or many of the other HOBBIES!
Nice work on the Angel Fish.
Very pretty fish; but, when I kept an aquarium, they were hard to keep alive very long.
