Rib Crowning Jig

[marco de lellis]

Hi Terry  " Maestro"
 
it's very interesting the vacuum sistem. (I fall in love)
some question:
do you use a specific vacuum bags? (how big)
how thick you cut the slice of spruce?
and do you use a different pattern ( radius) and lenght?
 
thank for your time
 
Marco

My approach to rib building is much like Ron Nossaman's, with the exception
that I vacuum-press my ribs. Picture below is of my two latest and greatest
rib cauls. I simply glued up a bunch of cheap 2x4s into a huge hunk of
spruce, drew my curve, cut them on the bandsaw and touched up the curve with
a hand plane.
 

 
Below is picture of laminae being clamped after glueup.
 

 
Below is picture of finished slab of ribs. Individual ribs are then ripped
from the slab to desired width.
 

 
Works great. I love making ribs this way.
