And I thought this was going to be a simple project! On the other hand, it's coming out really well, but with a lot more work than I expected.
First, since the feedback from my testers was that the prototype bowls needed more weight, I had to come up with a practical and attractive way to do that. Thank goodness I saved some old lead sinkers--they were just the thing, but they're not sold in NY, so I need to go to CT for a fresh supply.
Then I needed to make a cutting pattern that could be attached to the inside of the bowl, since that's the way it has to be cut to use the scroll saw. My prototypes were marked on the outside, then I drilled little holes to outline the pattern, but that was far too messy to impose on others. Fortunately, that was easier than I expected, since I had one of my prototype bowls to copy. And I had some small spiral blades standing at the ready, in case the regular blades didn't reach all the areas to be cut. They did--but barely.
Last, I had to work out a systematic way of smoothing and sanding the cutout areas. That's the challenge when you're writing instructions. You can't simply say, "Sand until it looks right". My little Dremel sanders, and the little carbide burrs did a good job, and I'm starting to get the hang of using them.
Now I'm waiting for the new supply of weights to arrive so I can finish up. Just hope the weather stays warm enough so I can heat my garage. I'll post pictures when I'm done--I think you'll like it.
