So I rang my mate Nick on Saturday morning around 9. We chatted about the project and general stuff, including the possibility of turning my plasma cutter into a CNC plasma cutter – which I’m quite excited about.

Nick was keyed up to make a spanner and I’m taking the nut round tonight, but he asked for some basic measurements. Number of teeth, outside diameter and depth of the teeth. At 11 I received the picture below by email. Looks pretty good doesn’t it? Clever Lad!

So the plan is to make a few mock up spanners in plastic for a trial fit. Once we have the best version it’ll be cut in steel, hardened if necessary and ready to use in anger! A big leap forward for the project, thanks Nick!
