    Hello all,
    Does anyone know the name of the profile t+g 22mm P5 chipboard is cut to?
    Simply, I need to router cut the same tongues and grooves on to chipboard to finish off a barn conversion floor.
    Thanks in advance.. :)
     
  2. Why have you ruined a Barn conversion laying a chipboard floor.
    Nothing to beat doing it correct and laying a timber floor with, either properly seasoned new timber or reclaimed timber.

    profiles vary a lot
    you would need a half inch router and table
    but you dont need to profile the edge as its cut to the wall
    so not sure what you mean

    the boards end from 2" to almost 8" from the wall.... the boards were laid straight and true, just a shame that the walls aren't!
    so I have to 'fill in' from the t+g long edge to the walls. i can use the corresponding boards, cutting off the 4" or so strips, but then need to mfr new tongues and grooves.
    or waste the rest of the boards! :-(

    How many board would you need to finish the project if using only one edge of full boards?

    Rip and slot it and use a loose tongue?

    I'm being dull here, so the last row of laid boards close to the wall have a butt/cut edge exposed? Don't understand you.

    I think what he's saying is that the remaining gap would only use a little bit of the next board with the rest being wasted.

    Ah right. In that case use a biscuit jointer coupled with polyurethane glue. Saves faffing about.

  14. If it had been set out properly you would have cut the first boards to fit,even if laying them later.
    There would have been no need to try and cut profiles on boards.
    A lot of extra work has been created.

    nope, cant get the biscuit cutter to the boards already laid.... :), only have 4" between the tongues/grooves and the wall...

    Then take up the laid row, remove the tongue/ groove, and cut slots with the jointer, then relay. Or go for your original, or chippies idea.

    the existing boards are PU glued down, and along the t+g joints.... we tried with the first one, it disintegrated...:-(

    Snap a parallel chalk line from the joint of the last board down the length of the boards allowing the clearance you need, then run a circular saw along a screwed down straight edge the correct depth, to cut through the boards, can take them up without damaging the edges of what's staying.

    Run a circular saw along at 45 degrees and lay the new pieces to match using polyurethane glue?
