Hi TT, I think this video has been put on this forum a year or so back, but I watched it again. It is a thorough test but as he points out JB Weld is a two part adhesive,
I would like to make a point about PVA or white glue. Nearly all modellers have spring type clamps holding the joint until it dries. These form brittle joints. If you clamp with a screw clamp the joint will not fail before the wood does.
I inadvertantly found out after having mistakenly glued up part of a boat hull wrongly. I had to undo the glue joint and reverse a part. there were some spring and some screw clamps used.
The spring clamped joint opened up with a knife blade inserted, the screw clamped would not open at all, the wood split apart.
I still use the spring clamps but not much, I now use screw clamps where ever I can.
Regards
Roy
