Just found a project for my new router

Good Evening All,

I just bought a router for the first time and have a project for it, but now I just need to find the right bit.

I have 3/4in Bruce Hardwoods throughout my house, I need to install one last room to be finished with this project. However, I have hit a little snag. Why I did one of the bedrooms, I got very lucky and the grooved ends were all lined up and none were cut, so I was able to use a slip tongue instead of a transition slip from the hallway into the bedroom. On the other end of the hallway, where the current project bedroom is, the boards are all cut, so I need to route a groove to accept a slip tongue. The issue that I am finding is that all of the T&G bits are made for use on a table-mounted router and are not meant to be used handheld with the flooring already installed.

Does anyone have any experience with this or advice as to what bit to use?

maybe a 1/4" slot cutter w/bearing? not sure what your slot size needs are, but you can make multiple passes or trim down your tongue...
that's a great idea. It needs to be a 1/4 tall x 1/4 deep so that may work. My only concern is the bearing, I would have to find one that rides on the top rather than sticking out from the bottom since the flooring is installed and I only have 1/4 from the bottom of the cut to the sub floor.
Table is far and away the best choice for T&G. If you do it hand held, it's really easy to slightly tip the router which messes up the tongue and/or groove. You can alleviate that by laying a second piece of your material parallel to the one you're cutting to support the router base.

Another thing would be an edge guide that will hold your router stable. Here's a picture of the Bosch unit, another of the DeWalt guide.

I completely understand that table is better, but since the flooring is already installed, I'm hesitant to try to take up a whole section of the board in the hallway just to be able to take them to the bench. I was planning on using another piece of scrap flooring on the other side of the opening, parallel as a counter section to set the router on to hopefully alleviate the tipping issue.

Will the edge guides work if I am routing on the edge of the board?
Either you or I am missing the point. Is part of the floor already installed? When talking about reversing direction I am talking about one floor going horizontal and the other going vertical. Is Jamma007 trying to install additional flooring that has a tongue on it to flooring that does not have a groove? If so, then good luck (especially for a non professional) to cut a groove/ slot into the existing floor. I would really like to see that slot when it reaches the wall. Maybe it could be cut with a chisel and an oscillating tool or maybe it could be cut with a kick saw or maybe it could just be only cut where it's easy to cut and then simply butt up the rest. Maybe if it was really necessary to have a slot then the guys in the above video doing boarders should be told that they are doing it wrong. The end tongue and groove help keep things lined up. A surface nail and adhesive will do the same thing.

The flooring in the hallway is already installed and is existing. Its a combination of tongue and straight cuts that they made when they installed it. Im going to cut it back square just a bit to loose the tounges and I would like to put a slip tongue in to make sure that the boards stay flush over time. I have previously done a room where I just but joined them and the boards weren't perfectly flush. Since its already installed I can cut the slip tongue to length. The width is only as wide as a doorway, so I was only going to put the tongue in as far as I can route a groove and leave the rest to butt up since it will be along the door frame.

Heres a picture for reference. This is at the other end when I did the previous bedroom where I got lucky and the grooved edges all lined up. (this was a test fit of the cut before the underlayment was installed.

The issue with just a butt joint here is that there are many different boards that may move over time and start to come up. A slip tounge will help them all stay flush.

*I don't want to lace them into the hallway because the hallway is running along the floor joist instead of across them the way I have always been told it should be run in a room.

You didn't put roofing felt down before installation?
I did, but I was just doing a test fit for my cuts. I always use roofing felt.
Thanks for all the recommendations. I got it all laid on Saturday and finished trimming it out yesterday. Now I need to find a new project for the router.

@TimPa. Thanks for posting that bit. Thats what I ended up using and it worked perfectly.
