Wood glue (MDF) that works without clamping?

[Alko]

Hi, gluing together a bookshelf in MDF with various angles for the sloped ceiling. One of the angles was 51 degrees, which my plunge saw can't handle. So I had to hand saw and then sand the cut, and of course it's not perfect. But now it needs to be attached to the end panel. What glue can I use for that? The cut isn't completely even and would need something gap-filling. The shelf is secured at the back to the back panel and won't carry much weight, so I'm not worried about that.

You could have cut 39 degrees from the other side.

You can use some montage glue like Tec 7, Superfix, Esstack, or similar.

The TS55 can handle 45 degrees, the table saw as well. Could I have done it in another way? It’s the same angle on the other side sas.

90-51=39

The second angle is 39 degrees.

90-51=39

The other angle is 39 degrees.

This is how it works. It's hard to see how I can get 51 degrees when the saw handles 45. But I have to admit I skipped a lot during the trigonometry lessons.

That's how it is. Hard to see how I'll achieve 51 degrees when the saw handles 45. But I must admit I wasn't very attentive during trigonometry lessons.

If a is 51 degrees then b is 39 degrees.

If a is 51 degrees, then b is 39 degrees.

Absolutely, we agree there, but it's difficult to utilize in practice when cutting an MDF board where the cut should be 51 degrees. Without some kind of ingenious jig, of course. Sure, if you think about it a bit, it's not at all impossible to make it happen, perhaps like in the image below, with the table saw then.

No, that's true. You can take the last few degrees with, for example, an electric planer or a table router if you have one.

If you had inverted the piece you beveled (the side instead of the top board), then my calculation should have worked, at least.

That sketch of the circular saw is a bit misleading because for most table saws, you tilt the blade towards the fence and not away from it.
