Human Powered Sled - Boat-o-Sled

I've made something which has no name. It could be called boato-o-sled because it allows to drive a sled powered by human by rowing like rowing a boat.
The project is really easy and very fast in built. It took me.. I don't know something like 1 hour to built and film all together.

Why to built something like it ? 1. for fun 2. for fun :) 3. to make Your wife said: 'what a stupid idea' ;-) 4. to go on sled without anyone 5. to use sled as a boat - e.g. as a gym activity

- wood thick enough to hold the weight

- old sled

-drill

- screws

You need old sled for he project. It could be both - metal or wooden - it doesn't meter. What is important the sled need to have wide enough construction which allow to drill them.

You need few pieces of wood to make arms, hand holders and hm.. pushers for the rear.
The dimensions depends on the sled You will use, but in my case it was:

2 pieces for hand holders - 60cm

2 pieces for the rear pushers - 90 cm (the longest)

2 pieces for the rear pusher pushers - 80 cm, althoguh later i shortened them to 50 cm

2 pieces for connecting rear pusher pushers with the hand holders - 30 cm

Note: The rear pushers (those which push the sled from the road) cann not by mounted to high from the bottom of the sled. If the pivot will be too high, You won't move, but You will push up Your sled with You on them).

In fact connecting the wooden parts are real easy. Just drill a holes for junctions and put the screws there and that's all.

Note: I make the wood which will move near the ground a little bit rounder than rectangular by cutting the edges with the hand saw.

I added the iron rods at the end of the pushers, to have a better grip. I recommend that.
I think that my construction is just basic idea which could be improved a lot e.g. I think that the angles could be better.

And that's all. Now Your kid (or even You) can row his own sled :)
