We've recently had the guys from our sponsor E3d at the shop to do some scanning on fragile magnesium accessory drive cases from the Sabre IIA. And while they were on site, they were kind enough to scan two of the sleeves from our engine as well.
The Sabre has two different sleeves, 12 of each. These are essentially opposites, with the only difference being the port to trunnion orientation; top right and bottom left are the same, and top left and bottom right are the same.
At this time, we've not had any luck in locating the original engineering drawings for Sabre sleeves. Using the information gathered from this process will be able to combine known dimensional information with the scanned port profiles and orientation to create new data for potential future production.
