I was going through the plans for all the metal parts. I'm going have them cut with water jet. I noticed the note on the "06 Spar Fittings" drawing the indicates that the holes are drilled undersized and reamed to 5/16". The holes for the AN3 bolts are shown as 0.187 so they are drilled to size. But because the water jetting isn't all that accurate I was going to cut the holes smaller and then just drill (or ream) them to size.
Reading through the form, quite a few builders have had the parts cut with water jet but I didn't find any mention of what size they had the holes cut. Any suggestions on what size should be used for water jet cutting for the 3/16" bolt holes?
As an aside the "COMPRESSION-TUBES.dwg" from the web has an error in the TB-4 part. The holes should have 1.5" between them. The one hole is drawn 1.813" from the other one. It is right at the bend.
