Two of the biggest problems with making your own water wheel are how to mount a metal axle into a wood hub and trying to get the axle exactly square to the wheel itself. An axle 1/4" out of square can make a 6 foot wheel wobble 1 1/2" inches. This adjustable metal hub plate allows you to adjust your axle so that you can minimize wheel wobble and it also allows you to balance your wheel when the balance changes due to waterlogging. These sets includes 2 adjustable hub plates, 2 industrial grade bearings and a steel axle. The axles are slightly undersized to slide easily into the bearings. Custom sizes are available.
The 7 1/2" plate set comes with a 1"x 28" axle and bearings and works well for most wheels up to 5 feet (up to 150 lbs dry weight) $240 shipping $25
The 10 1/4" plate set with a 1 3/4"x 34" axle and bearings and will handle most wheels from 5 to 8 feet $320 shipping $40
The 15" plate set with a 1 3/4" axle and bearings and will handle most wheels from 7 to 9 feet (up to 600 lbs dry weight) with 8 or 12 spokes. $380 shipping $50
note: since different people use different numbers of spokes these hub plates don't have the bolt holes for the spoke bolts drilled in them. You will need to drill them yourself or give me a call and my machinest can predrill the holes for you to match up with your spokes (about $20 - $40)
