My Dad has asked me to go over and help fix up a cupboard in their

it is the best way, any other suggestions?

I should go very easy if you're drilling it, a "normal" hammer
drill should be OK unless you hit a bit of metak re-inforcing bar
- if you use a high-energy SDS you may crack panels, they're
surprisingly thin. Make sure all panels are held on properly, someimes
internal
(4x2 sheet steel with a hole in the middle) plates go missing. Use
galvanized bolts, head outside, not BZP.

Fix to the posts

What's the problem ?

Concrete panel garages usually have concrete posts too.

I spent a year building these things

If it's a compton or a banbury , you have posts to build on to

I'm just guessing that the posts are concrete, otherwise this post would
have been along the lines of 'how do I screw into timber posts?'
