    Hi,
    Trying to match an original skirting in the house but cant seem to find the right router bit.
    It seems like a roundover or bullnose but im not sure if they would give me the same profile.
    Picture in the next comment as the app wont allow you to include pictures in rhe original post

    I would say a combination of 2 bits. One for the rounding over, and one for the v groove.

    It looks like a bullnose profile to me. Have a search on www.wealdentool.com and you should find it. Best done on a router table with a featherboard unless you have a spindle.

    I doubt you can get a single bit to do both the vee groove and the roundover.

    You can get a roundover bit with a square groove that you could use.

    You could re grind the square shoulder for a vee groove, but its tricky.

    You could get the bit profile specially made, but expensive.

    Like i said, its going to take two router bits, or regrind the square shoulder roundover bit to suit a vee groove......or spindle

    If you can score the boards with a 45 degree cut using a table saw to make the groove, you'd finish the profile with a roundover bit in the router. You'd even manage it with a circular saw or tracksaw if you set up correctly.

    The first thing I thought to myself was just how easily that would be replicated using a plough plane and suitable cutters. I'm guessing you need a good few feet of skirting though, right?

    Would a scratch bead, using a piece of wood and a screw similar to the one in the picture make the v groove

    Would you have a photo of the side profile ? Would help if knew the thickness of the board as well, could guess the radius then

    You could make a perfect scratch stock tool to do the profile, if thats the route

    you want to take for a small amount of material. Large amounts need a powertool

    input.

    Thats not the same as a roundover profile,:)
