This is my favourite saw now, even for wood.

I squared the blade in every direction, which meant that I had to add two 1.5 mm washers under the front of the vise to get the blade vertically aligned.

Now the saw cuts in perfect 90° angles in every direction and it is of course repeatable.

I also made a small improvement, added a wooden block to support the cut off piece so that it won't fall and rip off the end just before the blade cuts through.
