Modifications for Fabrication
Main item: resesign for 'stock steel erector-set, Lego-set-like design while retaining performance and ease of use. Allow for replacement of boom/stick elements with longer or shorter versions.
- Need to work out specifics of rotation mechanism
- Simplify boom and stick for use of standard stock steel like the LifeTrac frame - 4x4x1/4 or x 3/8 tubing
- Design quick attach buckets
- Design for disassembly whenever possible
- Retain design for quick attach (QA) plate with seat.
- Will need to acknowledge tractor steering from the seat - such as additional wheel control valve for LifeTrac wheeels.
- Will need to acknowledge migration to Bobcat standard quick attach plate, with universal breadboard quick attach plate for rapid prototyping of attachments - there is insufficient flexibility in QA attachment with Bobcat standard alone
