I'm going to be building a small-ish deck at home, approx 22sqm. I'd like to use concealed fixings for the deck boards, but concerned about how effective they are. This jig looks nice and simple, but I'm concerned about the boards cupping: www.carbatec.com.au/joinery-and-adhesives/pockethole-jigs-and-accessories/pockethole-jigs/kreg-deck-jig#The only other way I know about is the steel fastners that fit into grooves, in the board edges, then screw down to the joist. The grooves are cut with a biscuit joiner, and you access the fastner via the gap between the boards. What if you need to replace a board, in the future? Can't see how you could do this, without removing a lot of other boards. Is neat face-fixing, which is what I did previously, still the way to go? Thanks for any suggestions. |

Did some more digging around, and the Kreg jig gets uniformly bad reviews.

Ya I've heard bad things on it as well. I don't do enough decks to really say what's best

There are Festool deck fastners, but you have to have a Domino mortiser and they are NOT cheap. Once i had figured out the price for a 40 sqm deck , i politely declined. And they might be NAINA.

Being it-challenged i can not post a link, but if you google Festool decking system , you'll find a PDF from festool.au. Hope this helps, Randal..

Decks in Timber Framing? ...... OK When I put in a small Ipe deck and bluestone patio about 6 years ago I used stainless screws along with Tiger Claw clips and will continue to use them. They do require using the biscuit cutter for the grooves. I still had to use stainless screws that were recessed and plugged at the edges, but I've never had issues with cupping. Replacing a board midway would be an issue as replacing that board would require starting from the ending edge and removing to the problem board, or bite the bullet and replace the singular board with screws and plugs.   |

Happy to have it moved, if there's a more appropriate section. Maybe the 'General' area? |

Lincoln, I'm still trying to figure out what goes where. Not a problem for me. I added a image of the clips.
Working with the clips is easy. I just laid out the boards, marked where the clips would be installed to the joists, then used the biscuit cutter to groove the boards at those locations. I could have left just the clips retain the boards at the ends but decided to fasten down with screws just in case. The screws go in at an angle to bring the boards in tight, but I used clamps to take that load when fastening. The only issue I really had was making sure I used the impact perpendicular to the screw and not over torque as the stainless square drive screws could strip out otherwise. That's a pain in the tail.
Thanks Charley. We wanted to do something to compliment the bluestone and not have bluestone across the entire back. It's a simple design where I wanted it to "float", so the footings are set inwards (they were there from the prior deck) and the rim joists carry the joist load to the girders so it could be as low as possible. Although the "float" isn't that apparent now as I put dwarf English Boxwood around the two open sides.
