Vaulted drywalled angled half ceiling (15'X13') and would like to attach barn wood planks.
It's an aesthetic ceiling - meaning it does not actually follow the roof. Rather, it is an angled "box" inside the attic, over that room, with a 2 foot gap between the top of the box and the inside of the actual roof.
The "ceiling box" does have seven 1.5" joists running down it, however, they are not very straight, they slightly curve all over the place.
The plan is to attach 3/4" thick by 6" wide reclaimed barn wood planks to the inside ceiling (as shown here) with wood screws (and construction adhesive), perpendicular to the joists of course. The wood all together is very heavy.
As a quick test, I held the plank up to the ceiling and checked for a known joist with the Zircon 740 - and NO reading, it is too dense I suppose ?
So, started marking the drywall with the center stud finder looks like this so far (not too good):
Next, when I place the 6 inch wood plank on the ceiling to attach it, it will obviously cover the line made for those 6 inches, so I will have to "project" where the line is for each plank as it goes up.
Between these two issues, I have less confidence that I will be drilling into the ceiling joist.
Given the situation and plank install - is there a way to confirm I have actually screwed the wood plank into the joist?
