So, let's do it
I purchased the gate and installation kit at Home Depot.
By positioning the gate on a vice I was able to mark the position of the holes.
Then I proceeded to make the hole, starting small and making larger until I created the needed diameter.
O.K. Honey bring on more alpacas, I am not afraid, I can make as many gates as will be needed
(Thanks to Techshop .....ahahaha...)
P.S.: never show alpacas for your wife.
I made it at Techshop
