I was this close to "signing out" on this project, due to a lack of enthusiasm. Robert and I now have a collective investment of thirty bucks (shipping is no longer cheap) and I have no personal interest in that the only way I will ever own a JLC GG1 is if one arrives free.
But I see there is still life here. If Harry wants to do the molds and cast these things, that would be ok - nobody will get rich on this project. But we really should coordinate!
Robert may have a bowed casting. If so, we will saw it carefully into two or four pieces, and then get Harry and Bob Stevenson on the same page so we only do this once.
Yes, it is my impression that only the main casting is failing. The "air line" as I recall is a separate piece, and will need to be moved to the new casting when the pilot casting is attached.
