Below is a table summarizing the process, as well as the approximate time that each step took.
| Approx. Time | Notes | |
|---|---|---|
| Design fins | 10 hours | We used the design from Hermes 1. Next time, we should do more detailed analysis. |
| Total design time | TBD | |
| Waterjet G10 | 3 hours | Make sure it doesn't delaminate by leading in to the cut |
| Waterjet phenolic | 3 hours | Make sure to weight down the part because it's long and thin and moves around. |
| Cut G10 tab | 4 hours | It's going to be difficult to get this accurate because sheet stock has a variable thickness. |
| Cut phenolic slot | 4 hours | Use machine oil or it'll get spicy. |
| Phenolic taper | 4 hours | Used 15-degree taper for Hermes 2. Taper may need to change for future designs. |
| Mill down phenolic | 2 hours | May or may not need to do this depending on the total thickness of CF on each side of the fin |
| Assemble fins | 2 hours | Don't use 5-minute epoxy. |
| Bevel fins | 4 hours | Did this by hand- could make a jig to get a better result and save time. |
| Total manufacturing time | 26 hours | The more you do it, the better you get, but allow for set-up and things going wrong. |
