Pulling Nails


Hi;
I need to cut some floorboards in the attic with a circular saw. I want to cut right on the center of the joist, but there are nails below the surface of the boards.
The last time I did this, I just cut the board, nails and all, and the saw didn't really complain, but I am afraid that I might shatter or just dull the blade if I cut too many nails.

What is the best way to pull nails that are below the surface of the board?

When I wanted to pull the entire floorboard, I was able to wedge a crowbar or large screwdriver and pry up the board enough to pull the nails partially out, and grab them with the claw hammer. But this time, I don't want to pull up the entire floorboard. I just need to cut out a section between two joists to access wiring.

Thanks

Fw

Pulling Nails


Won't the claw on my hammer do the same thing?

The nails are buried (blind), so I need to first get the heads above the surface to pull them.

I was thinking there might be some sort of tool that would dig through the wood to expose the nail. I guess I could use a drill, or just use the circular saw and let it cut through the nails.

the cat's paw at Amazon (or a local tool supplier) is for digging out those nails.
There will be no extra points for 'pretty', but it works great.

or you can cut next to the joists, and then scab in a piece of 2x4 for a nailer when you are ready to put the boards back down.

No the claw of your hammer won't digg into the wood like the tools shown in that link. Like jl said it won't be pretty but the tools in that link are designed to be driven into the wood under the nail head and pull it just above the surface to be pulled with your hammer.

Here's what I would do. I take a 4 1/2 ich grinder with a metal cutting resin blade and go over each nail in the direction of the saw cut. Then once the nail is ground down I'd take my circular saw and set the depth to the thickness of the floorboard (no deeper) and make my cut. Use eye protection and a dust mask and don't be surprised if some smoke is formed when the metal cutting blade cuts wood.

Or you can get a circular saw blade specifically designed to cut wood and nails (these are sometimes called demolition blades). Then you don't have to worry about damaging the blade. The cut won't be as nice as a finer blade, but the blade is tough as nails.

Anyone that owns and uses a hammer should own a cats paw too.

that's what I did for a previous job, but I was trying to avoid that. I guess in the end, it's easier than having to purchase a new tool, and then do the extra work of digging the nails out. But I'll take a look at the "cat's paw", because it will come in handy for other work I need to do in the attic, and elsewhere.

Don't own a grinder. Maybe just use the demolition circular blade? Or just cut next to the joist as suggested.

No. Correct that. He owns me

I'll go to HD tomorrow and buy the Pro Claw Nail Puller. That will be a very handy tool to have. Don't know why I didn't buy one 25 years ago!

Whatever brand you buy spend $15 and not $6 on the Chinese knock off.

Careful cutting a board with nails in the house w/windows
Hit a nail the right way & the saw will catch it & spit it out at high speed
Glass does not like this......
