Woodpecker has brought the square back!

Check the screws when you take delivery and regularly thereafter.  THEY WILL LOOSEN!.  I was asking for it because I clamped mine down and used it as a guide for power tools and I suppose the vibration loosened them. 

It's fussy to get them back in place and locked down.  There's only a small amount of play in the holes but it is enough set it off quit a bit way out at that 26" extremity. 

Relying on friction is not good.  Ideally it would be one monolithic object machined from a single piece of aluminum.  I suppose that would have pushed the cost out of sight or perhaps that isn't feasible.  Barring that there should be positive machined locking, a key way or slot or something, for the side pieces.   Or even the stainless steel pins that the 12" has.

Couldn't you put a drop of Loctite Blue on the threads? It's made to be removable with hand tools, but won't allow vibrations to loosen the screws.

As I recall there was something blue on the screws.  Probably Loctite.  It still let go.

WoodPeckers just put up the 6 & 8" models  deadline in the middle of sept.

Thanks for the heads up, I'll check that.

As indicated, machining a square this large from one piece of metal would cost a fortune. As for the screws loosening up, has anyone else run into this? We do not use locktite or any other anerobic when assembling the squares. I've been considering adding the stainless steel pins but because they're press fit, there's a risk of metal deformation causing permanent deviation from true square. We are mostly successful with the pins in the 1281 because of it's size. I'll experiment with some other mechanical options when we get to machining this next batch later this fall. Thanks for everyone's support on FOG. Beats a stick in the eye.

Based on posts here I had checked the screws in all my Woodpecker's squares and T-squares a few days ago.  They were all tight except the ones in the 26" square. That is the one I have used a few times as a fence to align the Domino when  cutting face mortises. So maybe it is tool vibration that is the cause of them loosening.

Does Woodpecker use Loctite (or something similar) on the screws?

In post #24 they said no loctite

I think it's great that WoodPeckers came on this thread , addressed the issue , asked for follow up & will look into a fix , that hopefully will lead to their improvement in producing  the next batch . 
My respect for WoodPeckers is growing more & more  [thumbs up]

Ah - yes, thanks.
