Drill Powered Outboard (Work in Progress)
- 1x Propeller of your choice
- 1x Handle
- 1x Bearing Support
- 2x Bearing Spacer
- 2x Bearing Cap
- 1x M10 Threaded Rod (I use 1000mm)
- 7x M10 Nuts
- 2x 26x10x8 Bearings
Printed out of ASA using a Flashforge Creator 3 V2 with the following settings:
- Layer height: 0.2mm
- Infill: 25% Gyroid/3D
- 5 Outer Layers
- 5 Top/Bottom Layers
- No supports (depending on your printer, you may prefer to support the propeller blades)
- No bed adhesion
- Propeller requires pause at 29 or 19mm (aggressive or mild, layer 145 or 94 at 0.2mm) in order to insert the nut.
- I print the propeller in one, and the handle assembly in another. But it's up to you!
The handle assembly acts as a frame to hold the bearings, bearing caps and spacers. The propeller has an embedded nut. Everything is tightened, and then locknuts placed across the primary nuts. The bearings can be tight, so you may need to scrape a little off of the edge of the hole. You can use the nuts and bearing caps to press them in.
I am going to include a handle option that can support itself on the back of a boat, to save wrists.
