Boy this kind of opens a can of worms. Like asking, "What is the best scroll saw blade?" I used blue painters tape for years and was not about to change because I thought it held all the right answers......no glue residue...could use a cheaper glue stick instead fo the the spendy spray adhesive....and I thought I had all the answers. The big draw back was the fiber raising on BB ply. Then one day about a year or so ago, I watched a video on applying directly to the wood and using mineral spirits to remove the pattern. It was a dream solution once I started to cut a lot of fret work. With the blue painters tape idea, I found removing 300 or more really small pieces of painters tape was a real pain but with the spray glue and mineral spirits the tiny pattern pieces almost fell ott the wood by themselves. Much less work oriented.
I never found a need for a blade lubricant until last week when I was cutting a really dense wood, of which I do not know the type of wood I was using, and the wood got really hot and the edges of the wood I was cutting, ( less than 1/4 inch thick), burned and blackened as I cut. I tried several blades and all resulted in a burning of the wood. I then remembered about the packing tape and thought I would give it a try and it did the job. I had tried it years ago for a lubricant becaseu if it worked it seemed like a good idea, but it was lead away from it the same as Paul, (Scrappile) was do to the saw dust coving the pattern, under the tape.
So depending on the wood you are using and the type of cutting you like, tape or no tape can be good or not so good. MY take on this
