I now have three points in and the new main line section cut ready. However I have run out of insulated joiners so there will be a gap (no pun intended) until I can get my hands on more.
No worry though because my spray booth arrived yesterday, so airbrush experimentation can commence.
I also some heavy duty side cutters (for £3) yesterday. These are immense and make light work of piano wire! Thanks to David Waller for the info. Thanks too go to various other people who came up with other methods for cutting. However nothing compares to these beastly cutters – simple and quick.
