Leg leveler length

Just a word about the length of the leg levelers. As mentioned earlier, we want to achieve a slope of 3,3° for the cab. So how long should the leg levelers be? They can be expanded to a max. length of 10cm. The length of the legs is 725mm (without the levelers).

So for the calculation, we have the desired angle of 3,3° and the length of hypothenuse of 1216mm. (the length of the cabinet's bottom) Let's do the math!



The rectangle triangle has a sum of 180° on all angles,
Alpha = 90° Beta = 3,3° so Gamma = 86,7°





That means we need the length of b which needs to be added to the length of the backside, then we can calculate the length for the leg levelers we need.

Here's the basic formula:

With the values we've got:

So we have approximately 70mm difference between the front and the backside when the cab is in a 3,3° slope. 

On the front side we have 104mm from the bottom hole to the bottom, which is c in the picture of the triangle above. On the backside it's 50mm from the bottom hole to the bottom plus the 70mm we've calculated.  That's a difference of 14mm.

That means, the leg levelers on the backside have to be 14mm longer than the front leg levelers.

For a better understanding, here's a bad drawing:
