This is a project that has been on the ToDo list for a long time, and I have finally had the time to do it.
It is a fairly advanced build, not recommended for beginners due to the number of parts and complicated build. The model Excavator is in 1/16th scale and is made from aluminium and Plaswood or Sintra (a type of closed cell PVC board used in outdoor signs and shop fitting)
The Scale Model Plans are for a static model, with fully moving parts. The finished model is capable of being converted to a full hydraulic Radio Controlled model for the more ambitious model engineer.
The model in this project is constructed with 2mm and 6mm sheets of Plaswood or Sintra (Closed Cell PVC Board) although this can be substituted for wood or other easily machinable material.
Parts are cut from the stock sheets and assembled following the Photo Build Guide that accompanies the plan set. There is no Step by Step Guide as such but each stage is covered by the Build Photographs and is a straight forward build for the experienced modeller.
The larger components are made of laminations of 2mm and 6mm sheet to avoid excessive material costs and enables the replica to be built in the home model engineers workshop. Parts can be cut using a Band Saw, Jigsaw, Scroll Saw or CNC Router and Laser Cutter. The plan set is compatible with all modern CAM software.
The 1/16th Scale Excavator Plans are in AutoCAD format and copied in Adobe PDF Format in full sized sheet template and Tiled A4 sheets that can be printed out on a home printer.
The model has full and free moving parts with the full range of movement.
The model excavator is based on the Liebherr 50 ton hydraulic Excavator and is scaled down to 1/16th size.
