Hi, everyone. Would need your advice how to repair this bow. Previous owner had installed screws to the bracket, but this made the bow useless for other limbs. I removed the screws and tried if it holds together but it gave creeky noise so I stopped. After inspecting it can be seen that the bracket has started to separate from the riser. I have an idea how to start but firtst would listen to yours. Please see pics. Thanks. Tamas

Do you have some more pictures? I'm not exactly understanding what you are saying. Bear TD limbs have a reputation for creaking" on some risers.

Creek was with latch. Removed the latch to be able to remove the screws. Hope you can see the 2 holes.

Please see on the front of the riser that instead of the wood there is painted epoxy.

Those two holes look like where two rubber plugs go. At least on my risers. Looks like he used those two holes to try and secure bracket to wood riser.

there were no rubber plugs on those brackets, only the mags had them as far as I know. The screw holes do not look like they go all the way through? If not then not sure why they are there other than to try and hold a loose bracket down. If the bracket will come out you can clean the glue off then try and re-glue it back in. I've seen others do it but I don't know what glue they used.

If recall correctly those brackets go deep into the wood riser, I don't think you will get them out without doing sever damage to the wood riser. If the bracket is loose, what I would do is countersink those holes and use flathead screws at least 3/4"-1" long to secure the bracket. If that eliminates the noise, then remove the screws and add some quality epoxy to the screws and reinsert them. Don't use the 5 minute crap, it doesn't have the strength needed.

What Bob said. Get some T-88 or similar quality epoxy to coat them with before installing them for good.

Tom are the screw holes all the way through the metal into the wood? Were the screws being used to hold the loose bracket or were being used to make limbs fit more tight?

Thanks everyone. I was planning to use Bob method. Hope I have plenty of material for countersinking. Attached pic shows the previus screws and the limbs which the previous owner modified. The holes do not go through the riser.

Thanks to hvac tec I got inspiration to turn this thread to a repair along. I am going to remove the bracket, applying gentle heating with a heat gun and reglue it back. Before the final decision I put on 30# limbs and drawed it back a couple of time to see what will happen. No creeking noise but slowly started to separeta, see pics attached.

I have seen MT-13 used for gluing osage or yew billet take down metal Sleeves, good stuff very strong. I use Smooth on EA-40 for gluing up fiberglass and wood bows.

Thanks for the advice. Made some progress. Managed to remove the bracket. It was not easy but not impossible. It took 2 hours. Heated with a heat gun and slowly started to remove it using a 65# limb. Let the pics tell the story.

Huntom:
Don't use the glue you have pictured it is not strong enough for that project and all that work will be for not. You want a slow cure, high strength product. You must have something like that in Hungary. If nothing order from ebay.

Not sure I totally understand either. I would return the screws to reinforce the glue but get flat headed screws. It don't take much to c'sink them. If the 2 holes don't go through the metal pretty sure they had press in rubber bumpers. Hope it works out good for you. >>>----> Ken

Thanks Joe, I will order smooth on soon. Ken I hope that I can reglue the bracket and it will be good as new. BEar did not install screws to hold the bracket in place therefore I am going to follow their steps.
I am convinced that smooth on is powerfull enough to keep the bracket in place.
At the moment the slot in the riser is almost clean, some glue residue is still there but will use the dremmel to remove it.
Also decided to remove the old finish, so the bow will be good as new. Also will attach a pic with another riser I already refinished.

Thanks for sharing this thread???? There’s been many posts on the Bear Bow group on FB re: these risers developing a hairline crack where the bracket forms a corner. After seeing how the bracket fits in the riser it’s easy to see the risers structural integrity is still maintained. The way that bracket is epoxied in there with twin fins and laminated future wood it’s probabl The strongest part of the riser.

Tom is doing a great job and it will work for sure. the way he is going about it will make a ten times better job than screws the right glue is stronger than the glue .the problem is the glue just fails sometimes .

Thanks Joe. It was cured above room temperature at approx 30 celsius. Was afraid to go higher in temp because the bracket was kept in place with plastic foil. I am sure this is enough. Hope that I can finish it till the end of next week.
