A buddy of mine owns a cabin on an island, but he's got MS and hasn't actually been able to reach the shore for several years. Several companies sell tracked wheelchairs in the 8k-16k$ range, so we're shooting for homemade. He acquired a power wheelchair, and I hope to convert it for him. A gas engine is not an option as it's Nature Conservancy land.
I'm hoping some of you might be able to help me with a few design questions I have. I'm camera-illiterate presently, but I'll try and resolve things soon so I can share pics as things progress.
Currently I have the wheelchair and 180x60x37 tracks (only) from a Honda power carrier. I hope to build track carriers using solid bogie wheels (ebay or similar) and probably homemade sprockets. I plan to utilize the chair's original joystick controller, batteries & charger, and drive motors. It looks like I'll scrap the original chair frame.
First question. I can buy Honda sprockets and hubs to fit the track for about $200 (but I do not know the i.d. of the hubs and the axles are NLA). Making them myself will allow me to determine the number of teeth, choose the hub i.d., plus may save money (labor's free, right?). A while back, one of you posted directions for laying out a sprocket, but danged if I can find the thread again. Can anyone help me with this info?
Have any of you here ever tried to build one of these, and have advice?
Thanks!
Paul
