OK...I'm going crazy now ... Going to do a combine tomorrow of a cut out that really had a SHB problem, and I could SWEAR I read a post on here about 'banging out' the SHB from the frames over a container of soapy water with 1/4" screen over the top. It sounded extremely logical to me at the time, and I built my "bang out" trap tonight...Now I can find the post to reinforce what was suggested.
Ideas any and all? Any help is appreciated! Thanks!
