Not a great deal of progress today as have been doing a bit of proper work for a change! Think I have come up with the solution for the hole though.

The CD box is 120mm and it just so happens that there is an adjustable hole drill that goes up to 120mm. It is worth a try but I am well aware that it will be at the maximum reach and may well make a hole that is not exactly round. Some scrap ply to start off with will be a good idea I think.

Anyway, one ordered for just over a fiver from Ebay (post free!) - you can never have too many tools!

This reminds me of one thing though - it is absolutely mo use having tools if you can't find them! I knew I had an automatic wire stripper somewhere and could really have done with it for wiring points the other day. Had a look in Maplin the other day and as they are £15 I decided I ought to have another look. This search didn't turn it up either but as soon as I wasn't looking for it I found it in a parts bin on the wall in my little workshop in the cellar. Point of this is that I really must tidy up the tools and workshop.
