Hi again yall.....
Im trying to catch myself in any mistakes before I unknowingly just roll past them and waste effort and materials.
I just noticed this. I have finished my cutting jig and about 1/2 way through making the form block (nose ribs)
I just went and looked through the plans---- and I cant find anywhere that there are diameters called out for the rib lightening holes. I hadnt really thought to look---
Page 4 shows the centers of the holes but nothing else.
What I did earlier was I had my blueprint shop blow up 3B which shows the holes. 3B says it is a 1/2 scale drawing so I had them blow it up 2X bigger.
I used the hole diameters from that without thinking. I did discover that the hole center marks on 3B do not match mylar wing form drawing #4. THIS
makes me think I shouldnt use 3B for any exact measurements..........
The ONLY dimensions I see, on 3B, are the skin rivet spacing and stiffener widths.
Am I correct making them match the blown up drawing 3B ?????? Dont see anything in the Bob book or Eric's CD.......
I am noticing the bend lines for the bevel on the holes will end up just barely fitting between the stiffeners it appears....... (the way I have the holes now.....)
I dont want to proceed till I think im on the right track........ and not going down a rabbit hole.....
