Re: Banebots 42mm gearbox: Recommendations for use
With all the work being done to solve the softer 56mm carrier plate issue, I haven't been really thinking about the 42mm plates. We still want to use them at 256:1 to drive our arm. Is anyone else still pursuing a 256:1-based arm?
I got a replacement carrier for the one I fractured, but it seems to be a slightly different version, so I am going to make new plates out of the left-over A2 tool steel I have from testing 56mm plates. At least I have a tempering process that I know works for getting this to HRC40. And this time I will take the pins out first. (To anyone just tuning in, I was able to harden the original 42mm carrier plate, which is, unlike the 56mm plate, tool steel, but the pins fractured.) I am going to make six (see attached), temper a few for testing, and save the rest as spares. If anyone wants the .dxf or an OMAX layout file, let me know.
