This is a pro tip right here. Thank you so much for this.

I wonder what kind of router I can use that will work in that 3/4 inch (installed height of the floor) workspace. Any hand held router tool that lets me do that?

I am curious what will I need the chisel or multitool for if I am using router to make grove in the both floor planks and nosing and using spline & glue to join them.

Chisel and multi-tool is used to clean up the corners and end of your circular saw cut, if, needed.

For routing, I recommend a medium-large size router. You want two hands on the machine for a clean cut and good control. A dustless unit will keep the dust down, although not needed. The extra amp will allow you to make a single cut. The large base will keep you square to the edge. You can use a trim router but, will need to make multiple passess and you can tip it, resulting in a oversize cut. Try and get a snug fit, you want to avoid as much up and down movement between floor and nosing. Specialty router bits for flooring splines can be purchased for around $75 . You can use a slotted bit, but will need to make your own splines.

The nosing will not need a groove. Common hardwood nosing already has one.

G & S Floor Service Thanks for the response those are helpful and bring some unforseen thing in to light ahead of time. Reading your comment making rethink in which direction I should laydown my floor.

attached is the layout of my current space. Previously I wanted to lay down the floor from front window to patio door, in that direction. Which I think can help me avoid having to use router tool. I will just need to make sure edge of grinte is 5 inch multiple away of transitiional nosing. 5 inches & half wide nosing lets me do that. Not sure if that would be too wide?

But then I watched a video where this designer girl recommended laying floor towards fireplace, which I am also curious about what you guys think of?

What direction would you run the flooring in, if it were you.

Uptown Floors after reading your comment I came by this video.

Something tells me this video makes it look little too easy.

If, you want to maintain the original manufactured edge. Yes, you can install the nosing first, then connect to the nosing and install towards opposite end for the nosing section.

You have to lay the floor perpendicular to your floor joist for a stiffer floor.

ok that settles it then, if I am to run the floor perpendicular to joists, then it has to be run perpendicular to windows.

Which is going to be great, because I measured today and it seems like using 5 inch and a quarter nosing will leave me about 150 inches between granite and nosing, which is exact multiple of my 5 inches wide floor planks.

Might have to cut nosing down by about 1/8 to 3/16 of an inch, but I might just endup sliding nosing out by that amount, Wouldn't be end of the world. I am just glad it didn't fall short. Fingers crossed on that one.

Only room for an error would come from the width of the wood plank now, as I have taken manufacturers word on that one. I will keep this thread updated to how it goes.

Thanks a ton guys really appreciate your input here.

in the end I finished the nosing at the very end. Started from fireplace. I just made sure I was running square. Had to work with an 1 inch strip at then end also routed it out to make things fit together.

I applied a lot of thing I learned in this thread on the project so thanks a lot you guys. Maybe not in exact order but it helped a ton.
