Unicycling/gardening crossover (again)

I just found a use for the ridiculously short spare seatpost that came with my coker…
… I just used it to mend the rear roller on my lawnmower !

I was hunting 'round the garage looking for some usefull oddment of plastic or metal that I could butcher that had a flat boltable side with a tube at 90 degrees in which to seat the rear axle.

Why did it take me so long to think of a unicycle seatpost!
