Piot drilled then opened up all holes on canopy trim. Will have to take apart and open up the glas holes and dimple the metal holes holding the glas. Washing the Corvair parts as I am building, starting to look a little bit better after second wash. Case has only been washed once so far. My four inch venturi is due on Thursday so I can finish the plumbing on the Artifical horizon.. Still have to do the plumbing on the LRI, panel and wing.. Then the engine when William Wynn delivers.
