Thanks everyone, trust me this first one has taken a lot of time and money. Trial and error practise and dirt! Oh and the odd cut, like accidentally resting my elbow on my grinding wheel whilst it was doing 4,000 rpm
I've invested in some old man machinery such as a bench mounted machine polisher, polishing compounds, drill, dremel, and heaps of wet and dry. Now that I've mastered the process it's now a case to reduce down the time in which to produce the final product.
With regard to fitting, the Instructions will be super clear with pictures. I'll even enclose my torque wrench if you don't have one to do the job with.
Again thanks chaps for the comments
