For a bunch of reasons, access from above is not so easy (not impossible, just awkward).
My stud detector just bleeps everywhere (because of the laths and nails).
The only thing I can think off is to drill a few test holes with a fine drill (e.g 3mm) until I hit a loft joist. I reckon I could end up doing a few of those for each fixing point, as the loft joists are not very accurately spaced (Victorian building).
Anyone have any tips to make the job easier?
Where I have to fix top plates parallel to the loft joists (and no doubt not directly underneath one) - I'm thinking to fix noggins above (fortunately these will be in a more accessible area), and then use 120-130mm screws to be sure to bite into the loft joists.
Any other recommended solutions?
