Planer Blade Change
Let start with the planer, as I have especially been curious of whats inside these things. The insides are basically: a motor, dust hood, three blade cutting head. This particular model DeWalt 735 provides a single T-handle allen wrench to remove all the bits needed for regular maintenance.

The manual says one can replace only the blades that are damaged or dull, but I wonder if one should always replace all three (which I did). After reassembly I planed a couple pieces of teak. They went through smooth and effortless. Of particular note, the planing was MUCH quieter, due to the sharp(er) blades. I suppose, as with most tools, a noisy cut often indicates a dull blade.
Finally, the admiral came home last week with a set of infeed/outfeed extensions for this planer. These help to support long pieces of wood during planing. Got those installed.

Band Saw Bearing Replacement
For the most of this project, the band saw has been used, not to cut wood, but composite materials (foam, fiberglass, coosa board, etc), usually with a carbide grit blade. I have rarely used a toothed blade or cut much wood. Admittedly, I have abused this tool such that some of the blade bearings have seized up and gone way out of alignment. The saw needs some TLC if it is to cut wood for finish trim. Last week the admiral also came home with band saw replacement bearings and new blades (various widths and teeth per inch).
