Main goals of this upgrade is:
1) Removing old Manesmann router
On the old Manesmann router, the shaft twisted,
so that it became unusable.
2) Inserting a more powerful router BOSCH POF 1200 AE
3) Enabling independent airflow to cool the router
To further improve the Premium Homemade Router Table technical
solution, I enabled an independent airflow to cool the router. That
prevents sawdust from entering the router.
