To lighten my resin swimbait I have been exploring casting hollowed pieces. The idea was to make a hollowed 1st segment with solid resin, then forming the following segments with resin and micro spheres to obtain an ideal weight. The first segment came out lighter and stronger than expected. I tested the shock resistance by repeated throwing onto a concrete floor. I took a lot of force to get it to crack. But a slight twist of either the line tie or hook hanger easily separates the two halves glued together. I am using devcon 2 ton (5 min) to join the two halves. Is there anything stronger? I think the weakness is the ability of the Devcon adhering to the resin. I do not use any release in my casting, and I lightly sand prior to gluing. Not sure what else I can do except increase surface area. Attached is a photo of 1/2 of the first segment.
