small gap in between plywood

[DrGonzo]

Because my room is not completely square, I have had to cut a long triangular shaped bit of plywood to fit in between 2 large sheets of plywood on the floor.
I could not get an exact fit so there is a 10mm gap at one end of the ply.
I think the tile will be supported by the ply anyway but is this okay or should I fill up the gap with adhesive? That part would then have adhesive on the floorboards...

What's the width at the other end? It looks like you have effectively created a plank with ply - that's not a good idea.

that was my crap diagram.
Actually at the other end, the 2 large pieces of ply touch.
Then I have this triangular shaped bit of ply in the middle.

If I didn't put the triangle in the middle, then it would have been on the left or right hand end to cover the area where I need to put tiles down.

The red is the small gap where you can see the floorboards underneath.
All ply is still level with each other.
The largest gap is 10mm at the pointy end.

A tile would fit here:

How wide is the centre piece at the bottom of the pic?

 

[DrGonzo]

96mm

The whole point of overboarding with ply is that it spreads the load out evenly over the floor. What you've effectively done is fit another small floorboard over the top of existing floorboards. This wouldn't have been an issue if you'd left the small piece for one of the edges of the room.
Your problem is not really at the end with the gap, it's the other end where you might come unstuck (pun intended).

 

[DrGonzo]

The floorboards run left to right.
The plywood boards run top to bottom. So, essentially criss crossed.
Won't that spread the load enough?

It might well do. But for the record this is possibly the daftest bit of overboarding I've come across - can I have an actual photo please?
