I am in the process of building now, the house is up, all rough-in work is complete and the siding is going on now.
One thing that concerns me is that there is a TON of nails all over the place. I dont want to do the finish grade and just bury them, I have two little kids (4 & 2) who I'm sure will accidentally find them.
I've seen the magnetic sweepers, not sure how well they would work on the rough job site.
I was thinking of getting 2-3 250lbs pull magnets from Harbour Freight and sticking them to my 6' grader blade. My thought was if I could keep the blade high enough to pick up the nails, but not necessarily have them get knocked off again.
Any other suggestions of ideas, would be greatly appreciated.
