Don't know if you finished deck board removal.I grind heads off with mini angle grinder.All 3"deck screws have no threads on shoulder,boards will pry right up.Most deck screws are hardened steel,pain to cut a lot of them.They are cheep, and I have been using mine daily. Well after watching several videos on removing old decking screws (keep in mind that I need to minimize the damage to the bottom side) I think I need around 25 of the 12" metal saws all blades to remove these. I went through 2 blades on 2 boards. Once cut, I flip the board over and using a punch remove the screw heads. Works good, but time and blade consuming.
Before you suggest, I did try the following;
Tap a Philips bit into the screw (Most just break off)
Drill and use a bit extractor. See above.
Cutting seems the cleanest way. A trip to HF payday is planned.
Project is on hold, Rain and work. Don't have an angle grinder. Still need to pick up a couple packs of 10" saws all blades. Good suggestion though, thanks.Don't know if you finished deck board removal.I grind heads off with mini angle grinder.All 3"deck screws have no threads on shoulder,boards will pry right up.Most deck screws are hardened steel,pain to cut a lot of them.
I guess that you lucky in the years that the old Roper's last. My issue was we had a Maytag top loader that lasted 25 years with no repairs and when the transmission went we got a new Maytag (Samsung built) front loader that my wife absolutely hated. She complained that the Maytag was never getting the cloths clean it smelled and she followed the recommendations. It had 3 control boards on it and after the 3rd one went after the extended warranty I took the wife over to the local appliance store and let her pick what she wanted, she had the salesman demo several different brands and he finally took her to a Speed Queen residential washer with the same guts as the laundromat machines. She actually went back to the old fashion agitator machine that she said actually got the cloths wet. That Speed Queen washer was what she wanted. She actually kept the Maytag dryer (also Samsung built) as it has been reliable and works well.Picked up a couple Ropers today, not the Tractor kind. It was bound to happen with the new house with all new appliances.... EXCEPT the washer and dryer. The complaints started a couple weeks ago, Takes two spin cycles, and two cycles to dry, bla bla bla. I don't know as I don't use them. So I get a call today saying the dryer isn't getting hot. Well I asked if She was happy with the Roper brand, and She said yes, as those lasted over 12 years. $800.00 for a new set wasn't too bad. And now seeing that all the appliances are new, and more Importantly She is happy. Maybe I can sell the old Ropers on Craig's list.
Good advise. I have an air chisel but the angle wouldn't work except for the outer boards (which I have already sawed through. The saws all lets me get right to the screw.I wonder if you could put a floor jack under the deck boards and put a 4x4 piece between the saddle on the jack and the deck board--perhaps if you place it close enough to where the screws or nails are ,they will pull out before the board cracks or breaks..
I remember seeing a guy use an air chisel to get siding boards off a house intact once too,without breaking that many--he used a pointed punch bit to drive the nails right thru the board..he tried using a chisel bit between the board and house to cut the nails,that didn't pan out too well..
I wonder if one of those new "zip" saws that will cut under mouldings with a metal blade would cut the nails ?..probably would,but the "reach" is too limited to get at the nails further inboard..
