Heat formed 1/4" locally? or a whole part WITH a heat gun?
Trying to gauge the tone of your remark here Mike.
Maybe a video or more explanation of your process? Thanks.
On another note: not having done a LOT Flame treating, it is something of an art from my experience. Mostly used it for prepping inlayed plastic parts in PVC foam core kiteboards prior to laminating carbon tops amd bottoms set in epoxy. good results, but I always wonder if I did it properly. "move flame at this many inches per second at this distance from material, etc"
On another note: for LW2500 or LW 3600, the area around tire opening does not have a "flange" to bolt to, so that is the crux of installing bolted on flat sheet bottoms unless a guy is will ing to blind fasten, relying on the actual fiberglass ski bottom to hold the fasteners in this area. Heck, it is known that some folks just sheetrock screw UHMW blind into the bottoms. maybe we are overthinking this!
