I recently received a table saw for my birthday to help me with some large furniture projects. I fitted it with a Diablo 40-tooth general purpose blade. For the time being it will be living in a "semi-public" workspace, so long as others adhere to a rules sheet that I am putting together. The short version of that sheet is
Use appropriately for a given task
Leave it as you found it
Point one has hit a bit of a snag; I would like to be able to clearly define when the blade should be temporarily swapped out. Officially this blade is "intended for cutting oak, pine, plywood, pressure treated lumber and boards". That's pretty vague, and I would like to be able to say something like "Only cut wood. If your wood is harder than ******* then this blade is not appropriate".
I was wondering if anybody could give me some guidance on this. While I do have some professional-level training in set building, I am overall fairly amateur at woodworking and I feel this is important to get right.
