at what angle the table for the knife is set, it is quite important when setting the stone's inclination angle

With the adjustable height on the threaded rod you adjust the angle. It can go pretty low so the angle is low as well.

Yes I know but I need a starting position. So I need to know what angle the table is to know how to set the stone. not all knives have a straight and smooth blade.

So I measured it from the picture. should be aproximatly good. Again, its not that critical. (you are adjusting the angle to the knife you have) If you want it eactly 17 deqrees you still have to measure it because it depends how wide the knife is ...

The length is not that important here. You can adjust the angle by vertical rod so its fine. But it needs to be long enough to accomodate the movement of the sharpening stone or in my case 3d printed holder for sandpaper and that is 170mm long. Dont have it with me anymore so I cant measure it now. but the smooth rod Im using is 500 mm .

I agree with @BestDay , how do we know the lengths of smoth rod and M8 & M10 threaded rod? It should have a correct size to create the correct angle to the knife.

For the M10 rods I calculated 260 mm from the front of the front stand to the back of the back stand. I measured the blind holed via CAD in the original design. You can add 2 times 10 mm for M10 washers and nuts (1x at front, 1x at end) + ~ 2 mm sawing buffer. I used ca. 282 mm.

EDIT: There is a picture with the measurements!

I can assume that the length for the M10 is 240 mm, and for the M8 it is 170 mm. Because this model is a revision of the one that is a reference: https://www.thingiverse.com/thing:2474245
