Glue for aluminum barrel into plastic chamber

Unread postAuthor: teebone66 » Tue Jan 28, 2014 5:26 am

I'm hoping to insert and seal barrels in the following scenarios:
Aluminum into plastic pill bottle.
Aluminum or copper into soda or Gatorade bottle.
I don't have any jb weld lying around but I do have 5 minute epoxy, sellys kneadit, and super glue.
All repleys gratefully recieved.

Epoxy should do for all those jobs, just remember to clean off those surfaces and rough them up a bit before applying.

also try mixing in some very fine metal shavings with the epoxy, it makes it stronger. When you epoxy on plastic, be careful, it reacts and the plastic sometimes warps/does weird stuff

Yeah 5 minute epoxy should work just fine, rough the metal and plastic surfaces with sandpaper to help the glue stick. Also im assuming you are making a mini combustion, they arnt high pressure so it should work just fine.
