  • Just add design decisions, considerations, and updates etc. Treat this as a paper trail.

    • The goal is that a random person should be able to pick up this log and get a really strong idea of your project and how it has reached the state that its currently in

Criteria:

  • Base needs to be sturdy

  • Ribs need to be (perfectly) parallel to each other, and perpendicular to the base in order to ensure curvature accuracy

  • Limit cost/try to use material already in the bay

Constraints

  • Ribs are being made out of metal

First Design

Base Cad: Using pipes already in the bay, a simple frame to support and hold the ribs was crafted. The tubes are 1.25” in diameter and aluminum.

The tubes (grey circular) will be welded together using a jig, and the ribs (Orange) will be welded with the same jig.

MDF Mold:

  • Made out of MDF, slots for ribs to be placed, with hardstops at the front and back to prevent movement.

  • MDF does not require welding

  • MDF base can be reused by removing the ribs from the slots and replacing them with new ones (that fit a different panel)

  • MDF will have to be purchased

Aluminum Tube Mold w/ Slots

  • Made out of tubes as cadded above

  • Tubes have slots that allow for ribs to be inserted and removed in the event of recycling a mold

  • This method uses tube we already have

  • This method does not require RIB welding

Aluminum and fully welded:

  • Sturdy and one shape use, very durable

  • Requires welding (will need to see what aluminum tubes can withstand)

  • No labels
