Hello,

I am in the process of modifying my deck a bit. I plan to mount a post (see image 1) and want to insert it slightly into the joist for extra stability. However, I need to cut a beam (see red lines in image 2) to do so. My first question is if it's okay to splice it with the other beam as shown in image 3. I assume I should use really sturdy stainless steel screws that go through all three beams. Any particular type?

My second question is if you have any good tips on how I can secure the post? I want it to be as stable as possible without an unreasonable amount of work :D

Thanks in advance!

Saw into the post instead so that you can nudge it down between existing joists. Screw the post with long screws or nails or dowel from a broomstick... (Clamp the joists together first), place blocks on each side as in the second picture.

Thanks for the response @Huzzbutt!

However, I suspect it's not such a good idea because there wouldn't be much left of the pole. It would probably break as soon as a kid climbs a bit on the railing. And I can't move it because it needs to be centered with the other poles.

Made a 3D sketch to demonstrate:

In the pictures, it looks like you can fit a 45xNN rule in the gap, why remove so much as you do in the sketch?

(Ok, I get it now, I think... That will be tricky to make stable unless you shift the post toward the camera.)

Wouldn't it work to cut out the beams so that you can lower the post like into a hole? The new short beam also reinforces the beams since one of the supporting beams will be completely cut off.

Can report that it's rock solid! Now only the handrail remains and to cut some decking boards :)
