Splice parquet without tongue on the gable end

[stefan.stor]

Just tore down a wall in the house to get a bigger TV room.
Was thinking of extending the parquet into the new room but now see it might be difficult without a molding (prefer not to have molding).
The short sides of the parquet boards are of course cut against the wall I tore down.

Can you buy some sort of tongue and groove kit or similar?

Feels like this should be a fairly common problem as many change the layout in their homes.

Glue a piece of plywood on the underside.

Tore down a wall in the house recently to create a larger TV room. I was thinking of extending the parquet into the new room but see now that it might be difficult without a trim (I prefer not to have a trim). The short side of the parquet boards are of course cut against the wall I demolished.

Is there some kind of tongue and groove kit or similar available?

You mill and use a loose tongue. Not quite sure how people do it at the ends though. You need a hand router and a suitable router bit. Cobolt is a good brand and it can be found here: https://www.tooltrust.se/for-overhandsfras/skivnotfrasar/skivnotfrasar-med-skaft

That would be an easy solution but plywood does add some thickness.
It could create a bump on the floors maybe?

One could try doing it on a loose piece to see how it turns out..

Then it will be generalskarv and the Not and fjäder is not the stiffest joint.

It's only at the ends I don't have tongue-and-groove, but maybe you can mill a groove in the short side to lock the gables a bit?

Then it'll be a general joint and tongue and groove isn't the stiffest joint.

The new floor will be laid in the blue area.
The general joint won't be that long, so I'll have to live with it.
I think a strip might be more noticeable.
The arrow shows where the end side of the boards is located.

Perhaps the best option would be plywood and also milling a groove in the ends so that the ends lock against each other a bit as well?

Perhaps the best is plywood and also to mill a groove in the end panels so that the end panels lock against each other a bit too?

Or you can cut the whole thing off straight from the corner to the outer wall. Splicing parquet like that with general seams will look like duck droppings. Depending on what kind of parquet you have, of course. But give it a try, it's hard to make it look nice.
It can't be that many square meters to lay in that whole niche anyway.
