BetICouldMake1 Posted November 17, 2018 Posted November 17, 2018 Somewhere I remember reading about dry rolling tubes with gum tape and then steaming them in a double boiler or slow cooker to activate the adhesive. Has anyone done this or can you point me to the thread? I've tried searching the forum but can't find anything. Probably user error but I can never get the search function here to play nice for me.

davidh Posted November 19, 2018 Posted November 19, 2018 Seconds in a pressure cooker will activate the gum and leave a rock hard tube.
Arthur Posted November 20, 2018 Posted November 20, 2018 Biggest issue I see is that tools are a fixed size and truly round, but unless wound on a mandrel tubes are not perfectly shaped.

Col Posted November 21, 2018 Posted November 21, 2018 Might have to dig out the old pressure cooker (unless its been hoofed) just to satisfy my curiousity

I'm not sure what your criticism is. The tubes are still wound on a mandrel, just not fully glued until briefly steamed. Wet rolled tubes are not (at least commercially) dried on the mandrel. I rolled some tubes last night and set them on a double boiler for maybe 10 seconds. Tubes set up nice and hard in just a few hours, no swelling or warping. I did give each one a quick twist on the mandrel to ensure the inner layer was down flat. If you're rolling small tubes for spolettes, inserts, or bottle rockets this is an awesome way to get nice tubes with no mess and without the dreaded telescope tube.
