What is a good metal to metal adhesive?
Question:I need to repair part of a broken bed frame made out of wrought iron. What can I use other than welding that will hold the weight of the mattress.
Answers:
Let's be real. the reason it broke in the first place is because it is in a high stress area of the frame. I am imagining a bond line that is relatively thin/narrow. For this application, your only shot at attempting to fix with a glue is a 2 part epoxy system. If you can, choose one that is 'toughened'. In other words, it has a lower young's modulus resulting in more flexibility before failure. You don't necessarily want a soft epoxy, just one that can take some shock and stress.
I think mechanical means are necessary in this app (without being able to see it). I would highly recommend a plate and some machine screws to hold the frame together. You could use the epoxy to adhere the plates to thei frame- this would give you the surface area you need insure the epoxy does not give.
The only good way to repair it is to weld it. You can use gas welding, or electric welding. If you use electric welding, don't use steel wire (MiG) or steel electrodes (arc) - use non-ferrous non-corrosive wire / electrodes ONLY.
Epoxy glue works Great!! Comes in two parts, resin and hardener, which you have to mix in equal parts then apply. This is the type of glue used on aircrafts.However, the repair should be as strong or stronger than the original piece. I do not think that the glue will do it alone. Personally, I would glue it and screw it to clamp glue down. Maybe use a bracket to support repair. Also, the larger the surface area that needs to be glued the better. Use self tapping screws or pre-drill hole slightly smaller than the screw size. Good luck.
Liquid nails. Be sure to clamp it.
It's not the weight of the mattress, buddy. It's the jumping up and down on it with your sweetie, getting your jollies!
THAT is tough on beds!
You cant weld cast iron. Pick up from hardware or auto parts store a JB instant weld. It is 2 tubes of paste that is nearly as strong as a weld. You just mix them together and apply. The stuff is great.
I might suggest that as a back up that you buy and place either a small clamp or a couple of bolts and nuts to augment the repair.Good luck
The closest thing I can think of to what you're looking for, is J B Weld. It's available at most Meijer stores, hardware stores, auto parts stores, large dept. stores. Even it may not hold the weight of a mattress and someone sleeping on it, but it's pretty good stuff. I've successfully used it to repair metal objects that I thought were just lost forever and they 've lasted years.
You can try epoxy putty. It is a two part substance in cylindrical form and is very simple to use. Just mix it between your fingers, per mfg's recommendations, and pack to the joint, hardens like steel. It's never let me down, hope it works for you.
Good luck!
gluing sounds like a lost cause. get a piece of narrow 1/8th inch steel and drill through this and the frame and bolt it together. its worth a try
