This is a bolt - how can I use a bolt on CLS timber? Drill through the whole 3" of the timber then attach the nut from the other side?

The timber is dangling on steel banding, so it's not rigid: Answer: Ok I will add ceiling support 3x2" CLS timber going from the nearest joist (which is not vertically above) down to the wood. Press upwards on the plasterboard in random places. If it moves upwards. Answer: I tested and it...

No need to be rude. I don't like leaving pics of my place as attachments in a random website so I use filelinks - filelinks expire attachments are there forever

2 sides are steel RSJ so I CANNOT attach the 3x2" CLS timber into those steel RSJs (drilling into steel RSJ/steel beams isn't good). The ONLY way to support these horizontal 3"x2" CLS timber is by using vertical 3"x2" dropping down from ceiling.

I'm looking to add a 7"x3" timber to support the end of a bit of 18mm plywood which is only supported on 3 sides not 4. Access will be underneath from the garage below. I don't want to take up the floor above only bare minimum floor. So the joist hanger can't 'fold' over the attaching joists (as...

Need a decent skimmer is all. Admit it wasn't a good job plasterboarding but it's 1st time.

I need advice on a 3"x2" suspended ceiling which did not need building control. The wooden framing was done in a corner of a 'to be' kitchen boarded by 2 load bearing walls and 2 steel beams. Idea was not to attach the CLS timber to the steel beams (to avoid weakening the steel beams) and to put...
