I have located the joists. Plan is to use the plywood board to span the gap and attach the plywood board with the mount already attached to the joists. I assume 3 screws each end of board into joists will suffice. I will be sitting under projector so don't want the thing coming off ceiling Are...

Cheers again. The mount plate is probably a couple of mm thick. I assume I don't need the length of the t nut to go all the way through the ply Was looking at 9mm t nuts and 18 mm ply

If I use 18mm ply and t nuts I assume I need 20 mm bolts. Screwfix sellots of m6 ones. Are there any that are more suitable to the t nuts than others Also last question I promise What screws should I get for attaching board to joists. How long and or thick etc. I don't want the board to come down

Do I need to route a shallow hole in the board. Just thinking that the board will not be flush with the top of the t pins

Cheers. I think I now understand. So basically I get a set of matching M size bolts. Drill corresponding sized holes through the board. Hammer in the t nuts through holes. Attach board to joists then attach mount to board Is there any benefit in using hardwood or softwood plywood.

Thankyou for the help

I am not sure what would be the best board to use. Looking for the one that will offer the most resistance to a weight hanging from a screw. Cheers

Cheers for that response. With the threaded inserts I assume I drill a guide hole through the whole of board and then a slightly bigger on the other side of board to fit the thread and then once thread is in place screw through board and into the thread cap. When you refer to bolts and...

I was not looking at a review of my projector. It's heavy as it's a very new 4k state of the art projector. I am also aware a joist will take the weight. I want to know if a piece of board would hold that weight. The thinner the board the better etc

I have a 15kg projector with a mount. The place I need to attach it to ceiling is smack between 2 joists. The projector plate which ideally should be at attached to joints in 2 places has 4 holes depending on which way joist runs. Now as I can't get the ceiling mount at a joist I was thinking...

Planning on running some simple trunking down the wall itself. I assumed that there would have to be some closer joist nearer to the wall or is the old 16 spacing not always accurate

I have marked the 2 joists with tape on ceiling. The wall behind is hollow and there are then stairs behind going upstairs.

How do I locate my ceilings joists. My living room is rectangular. I bought a cheap joist finder and think I have found some running parallel to the longer sides of the room. However the closest one to the internal wall next to stairs is around 20 inches away but there is no other one close to...

I live in a house built 1980. Its got a carpeted living room. I wanted new laminate and have a friend who can fit it. Anyway took a fake chimney down and can see that under carpet there is under lay and under that is wooden laminate. Now I don't know why original owner laid carpet over it...

Cheers. Originally there must have been some device running off that fused box. Not sure what though. Would an old boiler use a spur. Just curious as to what would have used the spur in the first place

As far as I can tell no.

Just did a quick test and found it's on the downstairs ring. The TV was usually being run from an extention lead.
