You are limited to 45, 90 and I think 22.5 degree cuts.
yes but not made for that it will take a while to cut through 2x4 and teeth on saw are made for fine precise cuts on baseboards or trim board pieces.
The clamps are ovoid in shape and work by cam action. They work well enough but I don't normally use them. Just one more small part to get lost.
It will accept 3" tall wood.
use a tape measure and measure the space inside the box
No. the box is almost 5" deep but only 3" wide.
This is nothing more than confusion over which dimension is W and which is L. The bed is 4-1/2 in. wide by 7 in. long.
If the baseboard is not wider than the box it will definitely cut it.
