I've been asked the same things a few times now so it's time to post something on the blog:

1. When assembling George L's cables with right-angle plugs, screw the cap down until it bottoms out.  It MUST be screwed all the way down until it's metal-to-metal else you run the risk of poor contact and of it working loose over time.

2. The best tool I've found for cutting George L's cable of either .155" or .225" size is a pair of pet nail/claw clippers.  The best model of clippers I've found is made by Mikki, model 6275-154 and costs around £5.  I will be stocking these later this year.
