I have a block plane I am considering hacking at a bit. its no big deal as planes go, a no name, no depth adjuster, no lateral adjuster, blade rests on a couple of raised bosses in the casting kind of block plane. it has the big wheel under the cap for tension, and both the wheel and the cap are cast iron, and the body casting while crudely finished is sound.
my thought is to set it up in the mill and drop the bed angle down as low as I can. so what I'm wondering is how low can I go. as it sits the mouth is gaping, but between dropping the bedding angle, going bevel down and perhaps going to a thicker blade the mouth should close right up. what I need is a blade that can perform with an extremely low angle of attack and the associated grind.
any thoughts?
