After many years of scrolling I thought I knew a fair bit but now realize I still have a bit to learn yet.

I was cutting a very fine pattern in Kari Pine and worked through blades progressively getting finer because the cuts were to aggressive and I was loosing control. I was down to a jig saw blade ( very fine ) and still had trouble so I blunted the blade by using a diamond file to take the edge off the blade. It worked and I was able to carry on with my project with confidence and no mistakes.

This piece of information just might assist others who have had the same problem.
