I am making a keychain/key holder for my son. I’m making it out of 14ga steel which I want to affix to another piece of 14ga steel behind it. I am powder coating both pieces different colors.
I am trying to figure out the best method of adhering them together. It’s rather small - 13" long by 2.5" high. He’s just going to hang it on his wall in the kitchen.
I thought of epoxy, rivets, screws (least favorite) or tack welding (tig). Just need some thoughts. This would obviously be done post-powdercoating.
I may just pick some of the stuff up anyway. I’m not sure if the thickness, didn’t want this project to have any type of a gap. I’m gonna use these smaller type hammer-on rivets and see how that works. Pics to come.
The kid just had his twenty birthday and he’s having a supercharger installed on his Lexus - this is all I can afford to do for him. Lol
VHB (very high bond) is wonderful stuff, works miracles. You can get different thickness and width.
These 2 piece signs are held together with one small strip on top and one on bottom.!
I can not.pull them.apart, the signs I assembled last fall are still together and they have been out all winter. 20200305_155538|500x500
Gunny:
I have used 2 part epoxy to set my large saw tooth hangers on the back of some of the signs I made. It will hold up to 250lbs. I did a little experiment to see how well it holds and it bent the sign metal and the bond never moved.
We make engraved name plates for our machines and when we went to powder-coating in the 90’s the adhesion between the plates and the machines was a huge problem. VHB was the best of the tapes but was only good for 3 years n an industrial sometimes filthy environment, we ended up using drive screws in the end. and they look the best, Kinda look like hammered rivets and they won’t fall out.
