Follow up on Raptor nails:
The Raptor nails rep sent me some 0.8 inch and 1 inch brad nails to test. I used a Ryobi brad nailer and tested to see which types of material I had on hand could be nailed to my backer board.
I started with a piece of pine 1x4 and found that both nails were able to fully penetrate the wood, though the 1" nails had a higher failure rate of about 20%.
Next I tried 3/4" plywood. This was a little more disappointing as I wasn’t able to get any 1" nails to penetrate, with more than half failing at or near the surface. I should clarify here what I mean by failure as opposed to penetration… I considered a failure to be the nail shattering on the surface of the material, whereas penetration could range from half the nail to sticking out the other side.
I was able to get a piece of 2/4" ply nailed to the backer board with two of the 0.8" nails, but more than half of the nails failed or didn’t penetrate through the plywood.
With 1/2" plywood the results for the 1" nails were about the same, but the success rate of the 0.8" nails was much better, with more than 50% of the nails fully penetrating and holding the wood to the backer board. Certainly, 50% is a high rate for having nails not fully penetrate, but it is a viable option for workpiece holding.
Next I tried OSB. This is an easy one to report on because all of the nails failed at the surface.
And finally 3/4" oak, which also had no full penetration, though some nails did embed, so perhaps a thinner piece might be usable.
I didn’t try and MDF as all I had was 1/4" thick stock, which the nails seemed to easily penetrate.
Removal of the nailed workpieces was as simple as I had hoped, with a sharp rap sideways causing the nails to break between the work piece and the backer board. A sharp knife took care of any part of the nail left standing proud.
So, my conclusion is that these nails are perfect for any softwood nailing, but expect to lose a bunch on the way to affixing 1/2" plywood, and OSB, 3/4" plywood, and 3/4" hardwood are a no go.
NOTE: I do want to stress that these tests were done with a nailer that I bought for being the lowest price, and that said nailer is not recommended by Raptor nails. A better nailer may have better results, and the Raptor specific nailers would undoubtably be best.
