That is absolutely BRILLIANT This man is a GENIUS!!!
Put this up on the horse Forum, there will be people queueing up to buy it!!!!!! I never liked the idea of driving an easy entry with a team- this is the answer- Get him to patent it ASAP-- you can do it on the internet, it is free and very quick. Just Google "Patenting" there is a whole website on it. Do it, before someone steals the idea, PLEASE
To those who have ask me to build them a wagon attachment.
This old man has built carts for 30 years. I have put my tools away and now share information with those who would like to try building their own cart.
If you would like to build this wagon attachment for resale, go for it. I think it would be popular with the mini crowed.
I also have information and pictures for building a pony, donkey and cob size cart using motor cycle wheels. It is to big for minis.
Thanks for your interest, hope to see a few cart/wagons in parades around the country.
