Patrick, you'll find plenty of disagreement on that question. Personally, I think a bridge plate is still a good idea, largely because I believe it creates a much more stable substrate for the bridge, i.e. it stiffens the area and helps limit cross grain wood movement (expansion and contraction of the spruce with changes in humidity) of the top, which helps ensure that the bridge will stay on over the years.

On the two pinless bridge guitars I made, I used a spruce bridge plate.

I have an acoustic bass guitar plan that has a rather simple pinless bridge. It is constructed the same as a pinned bridge but the pin holes are drilled at a 15 degree angle, the top of the hole being tilted to the tail of the guitar. The bridge is slotted as one would do for unslotteed pins and the pins are eliminated. I have yet to build one of these. Is there a flaw to this solution? Perhaps a reason it would work on a bass and not a standard six string?

Anyone?

Nice looking bridge Fillipo, and very nicely seated from the looks of it.

The only 2 things I dont like about that style of pinless (strings mounted on pins), is if you use daddarios, you get a rainbow effect from the ball ends (on one pinless I did, I made sure the holes in the rear of the bridge were deep enough to NOT see the ball ends). There is also no ability to increase the break angle of the string at the saddle as compared to a pin bridge, where I get to decide where the holes go,and how much to ramp the slots ..... I prefer a bit more angle than you have there, and I think it translates into more tone/volume transfer.
