I am considering a modification to a home made seed drill that currently has the seed plates mounted vertically on a drive shaft and they are cut into small seed boxes, supplied by a larger hopper above, to pick up seed. I sow a wide range of seeds from vetch through to large fava beans and the current system is not satisfactory for all sizes.
I want to change the drive from rotational forward through a gearing to horizontal - exactly the same as a pair of bevel gears would. The seed plates (to be made in diffetrent sizes) would sit horizontally in the bottom of the seed box and drop the seeds through a hole in the base of the box and into the feeder tubes for the sowing tines. There is very little force needed to turn the shaft and I wondered whether I could use cage gears I make myself. Any comments greatly appreciated.
