Before we actually start putting pencil to paper (or rather mouse to CAD, in this case), we need to outline some basic needs and layout of the duck. Let's start with the problems and solutions analysis that we did on the design.
The following table lists the problems and solutions we worked up; although the original table was handwritten, this one is far more legible:
|
Problems we'll encounter |
Solutions |
|
Water leaking into seams of the model |
CA glue seams, and fill with silicone sealant. |
|
Water leaking into the location where the propeller shaft meets up with the body |
Stationary sleeve for shaft filled with grease and sealed (on the outside) with silicone. |
|
Water leak on access lid |
