Optical centre finder/punch 1500 subscriber

Gday, A couple of weeks ago I made a optical centre finder/punch and shared a photo in my Instagram page, I had quite a bit of interest asking if I had made a video on the build, after using it a few times I realised there was a couple of changes I need top make so I decided to make another one and bring you guys along to show how I made mine, hopefully you'll enjoy this build as much as I did making it, also i've crossed the 1500 subscribers and i'm going to do the draw in about a weeks time, please entry if you haven't already done so in the past, my email to enter the draw is [email protected] all I need is your name and you'll be put I the draw, Cheers Matty
