I've been watching him a bit on his You Tube channel too. I like his video on cutting in the patches on a 45 degree angle to close the gaps before migging them in.
Have not seen Tony here in awhile. He used to post those tutorials here but I guess he gets more eyeballs over there.
I love any tech and the more people i see doing what they do and how they do it , helps to fill my memory bank up . I like that he does it low buck > Thank you for sharing.
