Many things influence the performance of your bandsaw and the outcome varies according to any one or many of those influences. The outcome is of course reflected in the quality of the cut left as the wood progresses into, along and through the cut. Identifying what causes poor cutting is often problematic because the variables are so diverse and range from the bandsaw blade type to the amount of pressure you apply where and when and then too the tension you apply to the many different saw blade types, widths and tooth types. I thought it would be interesting to look at this as we investigate bandsaws, bandsaw blades, bandsaw use and so on. I produced these cuts using different blades, different tensions and different pressures. If this outcome doesn’t seem confusing then nothing will but believe me, there is rhythm and harmonics in the whole. Below you can see what happened to the right of the piece of wood and how after the initial start the score started to set up its own pulse rate. I changed the tension as the wood progressed into the cutting blade and new tension disallowed the more dramatic variance.

It will be an interesting journey but one that should bring ever greater clarity to an amazing workhorse.

    Look forward to more discussion and pointers for bandsaws. I’ve just renovated a second hand Record BS350 (14 inch throat) that really had been abused by its previous owner. It’s now in full working order with lots of new parts replacing worn out or missing parts but I have hardly used it so far. I took some guesses as regards spare blades (TPI and widths etc) but I’m always open to being educated.

    So excited for this particular line of blog posts and/or masterclass topics.

      And me.

      I watched the initial cuts of the round-bottomed plane using the bandsaw with interest … and a little bit of nervousness for how near to the blade Paul operates!

  • Mike Z. on A Future PastGreat stories and pictures to boot! I think part of why your teaching methods work so well is the time you spent on both sides of the Atlantic ocean - not an easy chasm to straddle…
  • Alain Briot on A Few Years AgoWho is Joseph? Your son? Thank you for the nice story.
  • Dave R on A Few Years AgoI also would love to see this toolchest as a project on WWMC.
  • Nick Jones on A Few Years AgoWhat a lovely story. Time with our kids is the most precious, rewarding and important time of our lives. Wonderful.
