When it comes down to it though, I'm not sure how different the different base plates are between pistons, because theoretically, the bore, main rod, and tie rods should be almost identical no matter which option we choose. For that reason, it makes most sense to go with this pistonoption, because it already has an acceptable COTS form factor and therefore requires not adjustments, though adjustments could be made to improve things. More specifically, we opt to use the 6453K143 because it provides an extra 1/2" margin on throw over the 6453K119.
Selected Piston Dimensions and Improvements

| Bore Diameter (in) | Bore Material | Stroke Length (in) | Rod Material | Rod Diameter (in) | |||
|---|---|---|---|---|---|---|---|
| 0.5 | Aluminum | 5" | 303 Stainless Steel | 1/4" |
Given a 4.5" coupling section, this gives us a 0.51" margin on separation distance.
Rod Improvements
The rod can be improved by making it out of aluminum instead of stainless steel. An estimate for mass savings is calculated below:
