Fasten the seat post to a plate and so on.. Could reuse the\nfork assembly as the azimuth bearing.\n\nThe motor and gear ratios are just scaling factors in equations.\n\nOne of my first instincts was to go after bicycle parts. This stuff is\nubitiquious.\n\nI suspect that it may be possible to find a new encoder of the\ncorrect type with a mount for a few dollars. One that is shaft mount,\nwith an appropriate output and no detents.\nIt might be the one bit of the project fit for a group buy.\nNorm n3ykf\n", "attachments": [] }
