Thanks for comment, yves78.
Indeed, this table saw is designed for cutting small pieces, as in modelism; tilting the blade was not a goal for me, so I preferred to keep it simple. For woodworking I have a commercial table saw, a radial saw, a miter saw and a band saw, all of which can perform bevel cuts.

Almost 4 years ago, when I made a table saw attachment for the Unimat lathe, I started a Pinterest board in order to gather ideas for this project, (https://es.pinterest.com/morsa00/mini-table-saw/). Over time the number of links has increased, many of which include a blade tilt mechanism and could inspire your project.

An alternative for bevel cuts is making slides where the work is presented at 45o to the blade.

A word of motivation: Since almost a year I already had all the elements to build this project, and I lacked decision to begin, but as soon as I started things went straightforward and I didn't stop until conclusion. Someone said: "once you begin a project, you have achieved more than 50% of the work".
