Just a quick update on the dilema the earlier post on wall fixings (dry-lined wall / battens for built-in desks) - in case anyone is interesed.
In the end I decided against legs-all-around, simply because I really wanted / preferred the idea of the (already cut) desktops being wall-to-wall and gaining much of their rigidity from the walls (so, rubber ducky decision point reversed!)
I then decided to use the simplest of the wall mounting methods (frame fixing plugs - thanks Mike Clarke), with the intention that if that wasn't sufficient, to progress to the next easiest (the dowel idea - thanks - Set Square) and finally onto what at work we agreed is the best solution, albeit the most disruptive - the embedded batten in wall, up to the block - thanks David Lang).
Anyway, to cut a long story short, the frame fixing screws/plugs worked a treat. I think for this application where 99% of the force is a sheer force applied down onto the battens, and supplemented by a couple of legs at the front then these do appear ideal.
Now, a couple of whinges -
Why does DIY take, say, 2 hours, but the shifting of 2 person's worth of junk in and out of another room (our bedroom, in this case) take 4? (hint: good idea using the bedroom - gave me incentive to move all the stuff back afterwards, that or sleep on the couch).
Why can we buy frame fixings with a posidrive head significantly larger than a "size 3" (whatever that is) - Wickes sell these, as do CPC (for significantly less than the sheds); But at 17:00 on a Friday evening you can't buy a suitable screwdriver? (the sheds only sell toy-screwdrivers, it'd seem).
Why then, do I have to consign my 10mm x 115mm, £1.50 for ten packs of frame fixings to the shed, and buy a pack of 16 for £10 from B&Q, just so that I can buy a screwdriver to fit? (B&Q sell frame fixings with smaller driver-sized heads).
Why do all the small independent tool stockist lock their doors at
17:00, when they advertise that they open 'til 17:30? (glares at Speedwell Tools / Preston)
...and Finally, why do a job like this on the weekend when the missus is off partying with her sisters - those frame fixings take some serious screwdriving - knackered my wrists - now what'm I supposed to do with the rest of the weekend?
(Sorry, but in case you hadn't noticed, I was getting mightily pissed-off on the whole screwdriver debacle - something to do with travelling a total of some 20 miles in rush-hour traffic over a period of nearly 2 hrs to buy a bloody screwdriver, and failing)
