We employ a huge CNC (Computer Numeric Controlled) Router. That means every part is cut exactly the same and perfectly.

This is Woody the wood cutter! He knows all the moves.

We program in microns. That's one thousandths of a millimeter!

Woody cuts to the thusandths of an inch accuracy.
That means all the bolts will line up and everything fits together perfectly.
