Can anybody tell me what they are doing with their lighthouse motors in the way of the manufactures recommendation about cooling the lower bearing by drilling a 1/4" hole in the plumbing for leakage. Is this really needed?
Here is their wording copied from their website:
"You must have at least 1/4"(Drilled Hole in the bottom of your table or plumbing) leakage per motor for proper cooling of the lower bearing. This must be filtered air - possibly using a filter like a ShopVac uses to cover the all holes that you have drilled. This will give you plenty of filtered surface air. If you come up with a better idea please tell us so we can tell others.
If you do not provide leakage air, you will destroy the motor and the warranty will not apply!"
