Steve, here is a little more on the topic.
Myths about Spin Grinding There are a lot of myths out there about grinding. In this issue we tackle two common myths with Express Dual and Anglemaster user Peter Fletcher, owner of PMG Consulting Services in Alicante, Spain.
The self-confessed �miserable old codger� is anything but miserable or old. Peter has been travelling the world recently helping to prepare some of the world's best golf courses for major tournaments.
In May and June of 2007, Peter has travelled around the world providing tournament support at the Volvo China Open, the BMW Asian Open, The Celtic Manor Resort Wales Open, the Open de France and the Italian Open. Along with an impressive amount of air miles, Peter has a tremendous amount of experience using spin grinders and here he helps us set the record straight.
Myth: Blade thinning keeps blades sharper, longer.
Fact: �Blade thinning, or relief grinding as it is commonly referred to, has no effect on sharpness at all. Relief grinding is carried out on the back edge of the blade and serves only to �relieve� the drag caused by contact between cylinder and bedknife.
It is the front edge of the blade where cutting takes place.�Myth: Quality of cut is guaranteed with a sharp reel and bedknife.
Fact: �The most important element to ensuring quality of cut is a sharp bedknife. A sharp bedknife (faced bedknife) will cut grass cleaner with mediocre sharp reel blades vs. a rounded edge bedknife and very sharp reel blades.�
