Could I use 18mm OSB board (such as that in weblink: https://www.travisperkins.co.uk/osb/structural-osb-3-2440mm-x-1220mm-x-18mm/p/803928) cut to 300mmx300mm instead of 18mm plywood? I already have 18mm OSB board offcuts lying around
Yeah but don't buy ply from B and Q its stupid money and their ply is s***, go to a builders merchant, use screws as last reply, I use glue as well, but its probably not needed but I always have some lying around, so for the sake of the amount needed I use it. I'd stick with ply.
Travis Perkins sell a fair priced 18mm OSB board. I assume that before I screw the 18mm 300mmx300mm OSB gussett into place that I first remove the existing bent nail holding strip?
I wouldn't use OSB stick with ply. Remove the steel plate so the ply sits tight, You can buy part boards at a builders merchant so you don't need a full sheet,
16 screws per 300mm x 300mm ply attaching that to the 3"x2" compression strut? Surely that's a bit much, that will remove a lot of the compression strut wood, I was thinking more around 5-6
Don't try to remove the plate: they are unbelievably difficult to get off. Ply will pull up happily with the plate in situ.
Hi Stevie22. the existing nail plate/nail strip holding the compression strut to the diagonal is already deformed/bent from myself trying to hammer the nails back into the compression strut (photo at https://u.pcloud.link/publink/show?code=XZS8oAkZDiqo3lF9nBLJMPcP2SXxdX0ITpy7). Should I not remove this plate before using 2 x 300mm square 18mm plywood gussets to secure either side using screws?
Ok I will leave the existing nail plate on and not remove it.Can I attach a 300mm square plywood gussett on the same side as the existing nail plate? Surely I would have to drill through the existing nail plate and into the compression strut
