Hello All ,
I am trying to repair and strengthen a cot. It has 3” round hardwood (rosewood) horizontal members that were cut in half for shipment reasons. To make it work a threaded bolt was stuck in one side and the nut on the order so both pieces screw in together. This was never a strong and precise joint and started to open up as the cot was used. You can see I screwed in a flat bracket to strengthen it but did not succeed.
I am asking experienced members to advise on best course of action to butt join these hardwood 3 in round pieces.

Is there any type of metal hardware that can be used to clamp these together or any other stronger joinery ?
