Hi everyone! Been a little bit here since an update.

Jay finally got the tooling and has machined the throttle shafts and is working on drilling the one oil hole at 6 degrees which Was an odd angle. Then he is not far from machining the rest of the head.

Here’s a picture of one of the Calliope engines apart!

Here’s the water jacket cores for the block. We poured them in an expoxy so that we could 3d scan them to put in cad and to make Greg’s life easier doing to block cad. 😁

A little Sunday morning photo dump of the start of the head tooling being scanned and modeled, so that Greg can assemble it all in cad to get all the exterior features of the head out of it.
