While I was at the East Coast show stepside's dad and mom asked if I would get their dump trailer working and of course I said yes no problem. It also helped that they had brought a banana split cake to sweeten the deal.
First off after building a few screw drives I thought this would be a piece off cake boy was I wrong. We weighed the trailer 8 Lbs then weighed it full of rubber 24 Lbs and found that it holds 16 Lbs. This box is 30 in long and proved to be a lot harder to lift than I thought it would be, so after making a gear box and completely making a new screw drive I got it to work and was able to lift 30 Lbs with a little effort on 7.2V. This box was bought from freddygeardrive as a box only and they were trying to do the screw drive themselves which they found out is a lot harder than it looks. Here is a video of the trailer lifting the 30 Lbs.
