I had a small compressor and 100 feet of hose already from Sears.
Pumped it up to 100lbs. Might need a little more, but max on the gun is 100lbs.
Tried it our on scrap nailing through 3/4" plywood plus 9/16" baseboard, adjusted it to the max setting and WOW-POW-BANG, went through both like butter.
It shoots 1-3/4" to 2-1/2" finish nails made by Bostitch from Home Depot.
I didn't need a pricey gun right now, maybe later.
Big dummy me, now I have to pry them apart.
Now I'm looking for things to nail. This is fun and no more bent over nails.
