on this site, I have heard and seen references to what look like brush bristles on a blank plate for cables to come through. Could someone give me a link to the topic that tells you how to make these.
where can I find the correct type of draught excluder because a google search shows me weird fancy designs
You can buy a strip from B+Q cheaply enough, it's designed to go on the bottom of a door, just slide the bristles out of the metal holder and cut to size
Dremel? i have used them to cut holes out of pc cases, guessing a blank plate would be thinner to so would be easier. Or drill pilot holes and then use a hacksaw
