This will be my first attempt at something like this do you have any advice or resources you could share? I'll most likely be making it out of plate welded together since i don't have access to a foundry or skills in molds.Thomashttps://www.blogger.com/profile/01745686976177673085noreply@blogger.comtag:blogger.com,1999:blog-7582974294685594749.post-70248835192365522282020-09-03T08:03:33.203-07:002020-09-03T08:03:33.203-07:00You would lose speed, but probably not torque.

I see you used a STMBL drive for yours. Do you know if the is any way to get one of these drives without self assembly currently? If not do you have any suggestions for valuable drives for the harmonic actuator used in your setup? Any assistance is appreciated.

I learn a lot, and there is something particularly satisfying about watching your projects go through the various machining steps. I try to avoid machining castings (something you apparently do fairly often), because there's not a parallel or perpendicular pair of surfaces.<br />Liberty4Everhttps://www.blogger.com/profile/10991932345322858593noreply@blogger.com
