Joining cedar

I am failing to join end grain to side grain with western red cedar. The joint falls a part with 2 test pieces using Titelbond III. The glue is new, and the wood is dried - bought from a lumber yard as dressed 2x4's.

I applied glue to the end grain first, and waited 10 min. Then applied more glue and clamped to the side grain piece. Waited 45 min then tested.

[Ultimately, I'll aid the joint with 2 mahogany dowels. But since it's for outdoors...would be nice to get more than only the dowel pins holding[.

Note: my first trial was end grain to end grain, clamped over night. No go, which made me switch to end to side grain.

Sorry to advise but end grain joined to anything is weak.

You will need to rely on the dowels for the strength.

The alternate is a mortise and tenon joint.

The end grain of cedar is very porous. Hard to make glue joint.

As stated a mortise and tenon joint is good. Even a half lap joint would be OK. You could even pin the half lap joint with a dowel.

If we knew more about your overall intent it would help.

I can't imagine why you would have an end to end joint for a new build unless it is some kind of mitre. I agree with George. Mortise and tenon sounds the way to go. Dowel may be ok too, depends on application, for that matter a biscuit joint might even work for what you want.

I am planing to use WRC to make a timber camper for my truck. My intension is to use mortise and tenon on main framing.
