tore down a poorly built mirror frame and reclaimed old frame to build new frame.

cutting miters with dws780 with the stock dewalt blade…its a 60 tooth dewalt carbide bladr that came with the dws780

during the process i overlooked a finishing nail and cut through it during a miter cut.

it was maybe 16/18 gauge nail.

any concerns here with my saw or blade?

i cut more miters thereafter with no issues….

thoughts/suggestions pls?

Look at the teeth, and see if you chipped any. Your sharpener may have to replace a tooth or 2 next time you take it in. It will cost more. On the other hand if it is a junk blade just use ‘til it’s dull then chuck it.

Finish nail? The blade didn’t feel a thing.

tks guys…ill take a look at the teeth tomorrow in daylight when i have her out for another project.

yeah..i barely felt/heard the nail during the cut…and this was a finishing nail from a nail gun…16 gauge max…

im more cocnerned if there is a piece of the nail in the guard assembly or down in thr miter arm (in the cavity between the kerf plates….

should that be a concern? or am i overthinking it?

i saw a clean cut of the nail on the waste side…but didnt bither to check the finish side of the cut for the nail.

problem is that finish side of the cut is hidden as i glued and nailed the frame together (lol)

of course if i had taken 2 seconds to check the other side and saw a clean nail cut on the other side…i wouldnt have this problem in my head

obvioslly the worry about nail part somewhere in the saw is worrying as im not looking ti have that catch in my blade during a cut…

With a good blade, especially with carbide teeth and the generally soft steel in a finishing nail, my gut feel is the nil was just cut away like the wood around it. So you have have some metal shavings, but I doubt you have anything big enough to ever be an operational worry with the saw.

I have a LARGE Rare Earth Magnet Epoxied and Set In Flush to the end of a 1” piece of Oak, 12” Long.

If I’m working with ANY Kind of OLD Wood I run this over it and BAM! If there’s any kind of Metal in there it almost Snatches it right out of my Hand! Simple but Effective.

You should be okay though with your Little Problem though.…

that is a really really good idea when repurposing wood..

i have plenty of magnets ..tks for the tip.

looking back…i was looking over all the wood for nails and knew about the head of the nail piece..which i cut at the old miter joint….

forgot about the 2nd half of the nail to look for on the other side of the adjacent miter piece.

btw the reason why i was thinking about having a nail piece that may have torn off was i saw another cut piece i did…and there was an empty nail hole visible…

im thinking that was simply a nail that was removed by the original builder of the mirror frame i tore down….
