I need to edge glue 2 5" sections of 1 inch (dimensional not nominal) PT lumber for a custom fabricated tread ( i need to match the existing treads so off the shelf lumber won't work). I am going to glue backers to span the glue joint on the underside of the tread leaving gaps for the stringers. Would gorilla glue work? BTW the PT lumber is dry ( as PT lumber goes)
Thanks Scot
