Hi there, We laid our lime floor slab just over a year ago. It is 100mm thick. We have been repairing walls and fitting roof windows and now come to partition up our internal space into the rooms we need. We are doing stud walls and need to screw our floor plates onto the floor slab. We expected the lime slab to be more friable when screwed into than concrete so expected to need rawl plugs for the screws. However as we drill into the slab the drill bit is tearing a wider hole than we need and we aren't sure how to resolve it. We need to find a way to avoid that or take a different approach to the partitions altogether. The drill rips the aggregate out of the slab so makes a wider hole than you are drilling for - you don't get a clean hole like you would with concrete. We have tried using a narrower drill bit but the width is still uncontrollable, partly because the drill bit can move around in the hole and partly cos the aggregate is torn out. Also the drilled material is not exiting the hole properly so the depth is spoiled by it falling into the hole also. Bit of a head scratcher at the moment... any sage words from the wise?

They work even when the user is blind(ed) OK, I was a bit cack-handed, let my glasses fall off my nose, and then - in - slow - motion, watched my size 10s stand on them. Waraneejit But -the good bit- I found I didn't need to see the screw head for the drill bit to engage and drive the screw. And neither did I need to be able to see the next few screws either. I could do everything by feel. Bless the inventor. Bet Torx was invented by a woman. That's it. Buying Torx only from now on.......

If - once more - I have to go to the BM to buy just 200 screws, I'll go mad. But before I buy 2000 of the wrong size, which sizes will I use most?

Shuttering came down this weekend: well, most of it. The shuttering was screwed onto the wall by gorillas. Some joker had given them several boxes of screws with which to play: here's one of each type. And, being fun-loving gorillas, they managed to burr at least 50% of the heads sink the screw so deep into the shuttering the screw was invisible destroy the heads put the screws deep into the wood at an angle so that it was possible to see that there was a screw in the wood, but it was impossible to tell the type of screw hid the screw behind a thin scrim of concrete I bought a proper set of (Na! Bosch naturlich!) screw-driver bits. I armed myself with patience and good humour. I balanced happily on a proper scaffolding tower. And by tea time on Saturday I had been transformed into a furious, fulminating Dervish, happily ready to rip the arms off the nearest gorilla and beat it to death with the soggy ends. I am I alone in this sentiment?
