    bonding brass to wood

    Not sure if anyone in here can help but it doesn't harm to ask & I know people will do other things apart from turning pens lol

    May have a job where I would like to inset a brass square (100mm) into the top of a post, I can pocket the top of the post out easy enough so the brass plate sits flushbut don't really want to use mechanical fastenings for security & overal looks.
    The posts will be either larch or Oak & obviously the brass plate will be bonded to end grain, these are for external use so out in the open.

    So just looking for thoughts on what might be a good adhesive to use under the circumstances

    For outside applications I like to use exterior latex caulk. Rough the glue side a little to give it some tooth. Apply an even coat and press firmly in place.

    Gorilla glue will also work but you will have to clamp it in place while the glue dries.
    You know your old when your sweetie says "lets go upstairs and make love" and you reply "honey, I can't do both."

    How big is it and does it have any form of load. So what is it for or is it purely decorative

    The brass squares re 100mm x 100mm x 5mm, posts are 150mm square, the brass parts will be set into the post tops so they are flush. These are rubbing posts, they are for a nature trail, the posts will be set in the ground at certain places around the trail so no loading what so ever on here the brass is joined to the post, it's just so you can do a brass rubbing as you walk round the nature trail, ere will be woodland animals on the brass for brass rubbing.

    Pics please to complete the request. Nothing to open up the inserted end to give a greater overall bonding of the chosen glue. Glue designed for airo space purposes these vdays are amazing.

    +1 for Sikaflex though there are several different types, I've used it a number of times to bond plastic to metal, aluminium to glassfibre ( just yesterday to fit a DAB aerial / alu plate on to my motorhome roof) and years ago to fit a heavy glassfibre spoiler to the boot lid of my BMW which I drove for 12000 miles without issue.

    There are several other makes just as good, I've also used this one Stixall Extreme Power - Ultimate combined building adhesive and sealant hybrid - 290ml - Black: Amazon.co.uk: DIY & Tools black but clear and other colours available. All are polyurethane based and waterproof but you would probably need to seal the wood before fixing as the adhesive works best on non absorbent surfaces.

    It grabs very quickly and you have little working time which is good for that type job but the adhesive once opened doesn't keep well, I put clingfilm over the nozzle before fitting the cap back on which helps.
