Precautionary reinforcement of holes in joists

[DKenn]

Ok, I can see the logic of smaller screw, I just didn't see a 10mm hole centred in the joist being a problem.

Can you get a drill in to bore the hole?

Whenever I have had to drill though joists, the drill and drill bit combo has always been too big to get in, so end up drilling an angles hole.

Not 30 °, peehsps caused by costa's length constraints.. 

but why 30°? Trusses are made with 45° straps.

I am pretty sure that I can reach using an angle drill. I was going to using a drill guide to get the hole started.

Just glue it.

Because if there were large loads to spread, past a big hole,  then a surface only connection isn't carrying the load into the core of the timber. It might distort or twist off....needs lab tests with coffee sticks and mugs.

Was measuring from the vertical. Basically an equilateral triangle.

@SteamyTea I hope you are going to re-emburse Costa for the obvious theft of the stirring sticks.
