Very impressive result overall! I probably would have gone with like super glue and baking soda then shaping by hand with a small Dremel bit or something. This is definitely prettier.
Nice strategy, personally I would just split them along the seam between two teeth. That way the transition is in line with the teeth and the effort required is much less.
Thats a great idea. In practice however, I think something like this might still be required due to misalignment during assembly. At least that was the case with these gears.
I think you might be able to avoid this process by prtinting yourself some assembly guides for the gear arc sections, basically an inverse gear sector that you clamp across the gap between two adjacent gear sections. It would also help if you split the sections along the bottom of the herringbone following the root of the tooth. But as far as repairing an existing part, this seems like a useful technique!
Thanks, yeah I considered some form of assembly jig / tooling but I decided to raw-dog it and see if that was good enough. Turns out I was close. If I were to build these again I'd probably look into some kind of alignment tooling.
@@designbydave Please do. Also, you quoted ~200 hours / 5 weeks on the process - I'm sure with some learning curve. Do you think that process could be optimized and the build time cut in half?
@@Guyvs3dPrintingI can't say. It's been a while so I don't recall what went into that time estimate, it may have included the CAD and prototype part printing.
