I always use clamps, a dust filter for my nose and mouth along with a set of quality safety goggles. I am fortunate enough to own a flexishaft Dremel, which makes guiding and holding the cutting tool so much easier than the standard models. I clamped the heatsink in place and cut out the required sections. Having cut out the heatsink sizes I needed, I then filed down the rough edges with a large flat file. Any problems please contact webmaster .
