WoodFishingRodHolders

Wooden Fishing Rod Holders

After freehand-sketching a model on Fusion, I CNCed these fishing rod holders. I then use the roter to curve the edges for a nicer finish.

Completed: October 2025
CNC Wood-Work Practical
WeldArt

Weld Art

After gaining some confidence with MIG welding, I attempted to make an art piece out of scrap metal where I use multiple weld angles. I sand blasted and grinded the scrap metal.

Completed: October 2025
Welding Metal-Work Art
TWeld

First Mig T-Weld

After some practice with MIG welding, tried doing a T-Weld to create a miniature stand for other projects. Welds came out well and strong.

Completed: October 2025
Welding Metal-Work Practical
FirstWeld

First MIG Welds

First time MIG welding on 16 gauge steel. Practiced using a swirling technique and correct speed/distance to create useful beads.

Completed: October 2025
Welding Metal-Work
Trout

Plasma Cut Trout

This project involved translating a 2D image into a vector-based sketch using Fusion 360. The design was then programmed via CAM to control a plasma cutter, resulting in a precise metal art piece. It showcases skills in digital design, manufacturing processes, and machine operation.

Completed: September 2025
Metal-Work Plasma Cut
Flywheel

3D Printed Flywheel

CADed 3D printed Flywheel used as a large scale model of future prototypes for engines and other projects.

Completed: August 2025
3D Printing Mechanics
Surfboard Holders

Surfboard Holders

A practical project to organize and display surfboards. Designed and installed custom wall-mounted holders using hand-tools.

Completed: January 2025
Hand-Tools Practical Woodworking
3D Print Crossbow

3D Printed Crossbow

An interactive 3D print that incorporates spring mechanics and string tension to create a functional, projectile-launching model.

Completed: December 2024
3D Printing Mechanics
3D Print Video Game Knife

Video Game Knife Replica

Created a 3D printed replica of a video game knife, featuring a synthetic rope handle wrap for an authentic look and feel.

Completed: December 2024
3D Printing Prototyping
Snake 3D Print

Articulated Snake 3D Print

An intermediate, multi-part 3D print designed with articulated joints to allow for realistic, snake-like movement.

Completed: November 2024
3D Printing Articulation
Lucky Cat 3D Print

Lucky Cat 3D Print

Our first project using a Creality 3D printer. A quick and simple print to learn the basics of slicing and machine operation.

Completed: October 2024
3D Printing Beginner
Fishing Rod PVC Holders

PVC Fishing Rod Holders

A cheap and effective solution to keep fishing rods out of the sand and water at the beach, constructed from PVC pipes.

Completed: September 2024
Hand-Tools Practical
