Design Goals
for the MDF Rose Engine Lathe 2.0

This document to outline the design goals around which the machine is specified.

Guiding Principles

Target User

  • The target user for the MDF rose engine lathe 2.0 is
    • An experienced woodturner, with
    • The basic woodworking skills that would have been garnered in shop class.

  • The design will ensure it can be built by the woodworker
    • Using a kit of parts we will provide, or by building their own according to instructions to be published,
    • Possessing basic woodworking skills, and
    • Using tools which can reasonably be expected to be available or easily accessible.

Overall Design

  • The intent is to stay consistent with the original overall design outlined by Jon Magill, especially the designs built into the rosettes.

  • The design will continue to use MDF as the primary building material for the headstock and base.

  • The design will include commonly implemented updates to the original design, including,
    • Stepper motor for the spindle drive,
    • Metal sheet on the lathe's bed,
    • Magnetic hold-downs (MagSwitches) for locking the cross slide into position on the lathe bed,
    • Front and rear rubbers, and
    • Amplitude adjusting (front rubbers only).

  • The design will not include previously offered features which would make the new overall design cumbersome or expensive. In particular, hand cranking capabilities will not be included.

  • The design will provision for known future options / expansions, including
    • Multiple stepper motors with controls for the multiple stepper motors, and
    • Pumping on the spindle.

Kit Offered for Sale

  • The design should enable a complete rose engine lathe to be built from a kit for less than $2,000. And the design should be designed to be lower if the user opts to make their own parts.

  • The kit offered for sale will provide options which, in total, will supply the hobbyist with all the parts needed (including the MDF).

    • Using standard, off-the-shelf parts, with a conscious decision being made when customized parts are to be used,

    • Sourcing parts from vendors likely to provide the parts for a reasonable time into the future (i.e., minimizing rework of the designs), and

    • Sourcing more expensive parts from vendors who will accommodate drop-shipments. This reduces the investment in inventory for the provider of the kits.
