I exclusively use the Tom Sexton's half cast method which I have modified a little. Use the Tom Sexton Fish Filler from McKenzie and have had issues on and off with slow setting, no setting, and fast setting. I can deal with that. However I seem to be having a new one and wondered if anyone else is experiencing this? I'm getting the skin of the fish pulling away from the filler creating drumming once the skin dries. Never had this issue until recently. Usually it's just back of the fish, but had a large crappie where it pulled away on the entire fish! I took the filler out, rehydrated the entire fish and remounted. Still pulled loose on the back side but I was able to deal with it. At first I thought perhaps I was using wood that is too hard for the inside block, and when running my screw in to fasten a stick to -- and hang the fish from the rafters --I was stressing the skin. But the latest fish, a yellow perch, I went out of my way to prevent that, by pre drilling the hole etc. Three days later the skin has pulled away from the back just above the seam. Maybe my humidity is too low? But I have doubts about that as I have two recirculating aquaculture tanks just down the hall that total about 500 gallons. I guess I can put a layer of glue the skin before putting in the fish filler but never had to do that before. Anybody else use the half cast method and have this happen lately? BTW called today to see if they had changed something but thy are closed to weather issues. Last time I complained about the setting time I got treated like a newbie and I was making it up. Don't remember the guy's name but he wasn't anyone I had ever heard of. Promised to call me back but never did.
