slow set hot glue for polystyrene!

[geperry]

I read a post a while back about using hot glue for joining polystyrene instead of using that really awful smelly glue (a mixture of: tetrahydroforan, Methyl Ethyl Keton, Ceyclohexanone, PVC Resin, CPVC Resin, Amorphous Silica and Acetone) that causes brain damage!
Well, I tried the hot glue I have at home, but it set too fast. Then I found some slow setting hot glue sticks at Home Depot! Still sets pretty quick, but works great. I needed something that set fairly quick, but gave me enough time to get the corner lined up. I'm making 70 frames that are 4 1/2 feet by 2 1/2 feet....... when using the poly smelly yucchy glue stuff, it didn't set fast enough and when I moved the frame around, it would come apart.
At any rate, this posting is just an FYI for anyone that the slow setting glue sticks work great!

Are you also adding V-nails? That seems to be a really large frame not to have some form of mechanical joining also.

Thanks for the tip. If I decide to try the plastic stuff again I'll try the technique.

Yes, I am adding V-nails.
