sorry i'm been less than attentive, i've been dealing with some personal problems and also with mites here in the real.

anyway, thank you all for the props, although all i did was to apply the principles i've learned doing a LOT of research. anyways, thanks

and McDanger, i'm glad it works as well for you as it does for me.

and polish, i used a 1inch hole saw, if you have 2 inch neoprene inserts, you can use a 2 inch saw,
lol, i know a guy who makes his inserts out of flip-flops (that would be shower shoes, or beach shoes, the flimsy rubber kind)
if you use pipe wrap like i did, a 1 inch hole saw will work.

and thanks for the thumbs up reap! (i've learned a thing or two from you dude)
