Cleaning Bits And Blades
Before attempting to sharpen either a router bit or saw blade. Clean off all the pitch, resin or glue build up. Soaking in a tray of Domestic oven and grill degreasant works well. Or there are specific “specialist” cleaners available but from what I can gather from woodworkers in general. There seems little difference in performance over and above the domestic cleaners. Please read and abide by the safety instructions of any cleaning product that you decide to use.
Blade And Bit Balance
It’s important for the balance of any high speed blade that when it’s being sharpened that each tooth or cutting face receives the same number of sharpening strokes.
Where To Start
When sharpening a saw blade use a marker pen to mark the point at which you start that will let you know which is the last tooth you need to sharpen.
All new diamond stones feel very coarse to the touch regardless of the micron or grit size of the diamond used.
This is a result of the plating process and is quite normal. The stone will bed after a few uses and the difference in grit will become more apparent.
Guilty as charged , As I’ve subsequently learnt I’ve always tended to use too much pressure when sharpening with Diamond stones.
It is absolutely the case that an easy light pressured sharpening stroke is all that is required to gain optimal performance from any of the Diamond stones.
To use too much pressure tears the diamond particles from its nickel bed - compromising the performance of the diamond stone and reducing its serviceable life dramatically.
Again its really down to personal preference as Diamond Cross sharpening stones can be used dry. We do recommend using a lubricant. Water works well or a purpose design lapping fluid but really it’s down to personal choice.
Warning by the very nature of the tools being sharpened i.e. they are ALL designed to cut something. In the wrong hands they can be very dangerous.
