Hello I love the backhoe, both the design and the workmanship. I have been looking at building one for a long time but could not find a design that I liked. Most of the other designs do not look like they would stand up to long term use. Your design is far superior to any others I have seen! What size plate did you use for the arms 13mm or 19mm? I would love to build a copy of your project if I could , would you be willing to sell a copy of your design or plans? I have a small farm and a tractor mounted backhoe would be very useful. thanks MELROG
