Use a high quality contact

Use a high quality contact cement designed for sticking high-pressure laminate (Formica) counter tops down. That works for me.

This is something I actually

This is something I actually know about :-)

I have done extensive trials to find a reliable way to stick brass to steel for this sort of thing:

and I can honestly say that the only adhesive that works is Household Goop:

Others tell me that other versions of Goop work too, expecially Plumbers', but I have no direct experience with that.

All epoxies (I tried at least 4 kinds) and CA glues failed miserably. Interestingly, although some say that E6000 is another version of Goop, it did not work anywhere near as well.

My limited experience with copper would sugest that the results are transferrable from brass.

I Second that

I have been using Shoe Goo,I think the original product by this company. I glue my gloves back together where the stitching fails. I also glue my "swampers"(winter boots) back together with this product.Its flexible and holds tenaciously. I use a bit of aluminum foil on the end of the tube to seal it and then place the tube in a glass jar to store it, otherwise it dries out. I never glued metal to metal, but wouldn't hesitate to use any GOOP product. Only if they made cars.....

A UK glue that I have found

A UK glue that I have found very good, but with a silly name, is "Serious Stuff" glue. It can be found easily in B&Q and, I think, Wilkinsons. I confess that I have not used it on copper, but I have used it on other materials that would not stick with anything else and, once stuck, I could not part them without destroying them. The parts are in a situation where they were subjected to high amounts of wear and movement and there have been no signs of failure. It is quite cheap and does not smell too bad at all: much better than Evo-stick or Bostik.

 

Regards,

 

James.

thanks james - is that a two

Sorry for the delay in

Sorry for the delay in replying: no, it is a single component glue. You can get it in either small tubes like Bostik or in those large cartridges like silicon sealant.

Regards,

My Household Goop tube is

My Household Goop tube is getting old so I bought a tube of Plumbers' Goop to try. I glued a piece of copper scrap (19G) to a piece of mild steel using the usual abrasive technique to prepare the surfaces and cleaning them with 99% isopropanol. The overlap was about 2 sq. cm. After 48 hours I had to clamp the copper piece in a vise and before I could separate the two pieces the copper bent several times. I would call it a pretty good result.

I recently made eight large

I recently made eight large copper wall panels for a client using very thin copper with a heavy verdigris patina. The copper was affixed to sealed plywood panels for mounting to the walls. I used a mastic designed for ceramic or fiberglass tiles and it performed exceptionally well. The advantage of the mastic is it has a high initial "grab" so the copper can be placed and then rolled out to perfectly flat, but it isn't like contact cement where repositioning is impossible once the bond is made.

I've used this mastic method for twenty years or so now and never had a failure, and that includes one kitchen range hood where the original hood was stainless steel and the client wanted it covered with hammered copper - it is still in place after ten or eleven years now..

Metal Adhesives

I just received an email discussing the comparison of mechanical fasteners, two sided tape and metal adhesives for manufacturing and fabrication. It took me to a website where there is a video demo, and PDF guides on selecting a metal adhesive. Here's a link:

Looks very interesting.

Bob, Henkle is a good outfit

Bob,

Henkle is a good outfit to deal with and the Loctite methylmethacrylate glue with activator is killer good stuff. I used to use it to adhere sawed brass letters to glass lobby doors on banks and never had a failure. Want it back off? No problem - just break the glass. (grin) Unless, of course, it is bank lobby glass 3/4" thick and laminated to boot. Those were definitely a one-way installation!

The activator was a neat deal since I could put the glue on the letter, place it on the glass and shift it until it was exactly perfect, then give the edge a quick spritz with the activator and it almost immediately set up the glue.

wow lots of ideas since i

wow lots of ideas since i last looked.. i used a contact adhesive called thixofix in the end, which has the advantage of you being able to fiddle about moving things for quite a while after first sticking. my only problem was that i was sticking pointy ended leaves, and despite pushing the tips downwards ever so slightly before sticking and keeping away from pressing the middle section too hard, i still have areas where i can get my finger nail under the edge.. : ( the glue was great, my method needs some refining... they were not in a great position to clamp, and i had not enough of the right shaped weights ready by the time i knew it was going to be an issue. its not terribley bad just a bit annoying. i am wondering wether to try to push a teeny bit of body filler under the edges of the few that i dont like. it would be tricky and it might make more mess trying to clean it up afterwards. and i have not much time now, so, i dunno what i'l do! thanks for all your advice though!
