I'm interested in making a P weight (channel weight for a backplate) to make up for my recently departed STA, and to add an extra pound or two that I'm lacking at the moment. I find that with a drysuit I get into a head-down attitude easily in the water (not so much floaty feet - I wear gators anyway), but just where my center of gravity happens to fall even with my tank mounted "aft" - so I'm thinking of making a P weight for just the bottom half of my backplate, to help counteract this tendancy, with the aim of giving me better trim.
Has anyone cast a P weight before with an integrated wingnut in it, so I could mount it using the lower bolt on the wing? Talking singles rig here, I would not be using it with doubles. The pictures of P weights I've seen on the web all look to be centered on the backplate, in between the 11" bolt holes - I want to mount one just in the bottom of the channel. Hoping to get 3 or 4 pounds in there. So I'm thinking that if I took a spare bolt, put it through the hole in the backplate, and screwed a wingnut onto it (sealing up any gaps with plumbers putty), I could pour the P weight into the channel around the in-situ wingnut, and then unscrew and discard the used bolt once it's cooled, leaving the wingnut permanently molded into the P weight. Then I could reassemble the rig with the normal bolt, and just tweak it with a screwdriver to hold everything in place - I no longer break my rig down to take the wing off the backplate for cleaning, so it could stay in place until I next need to dive doubles.
any thoughts?
