The chipmunk is good value and a great airplane but I am spoiled now by modern CAD based designed. The spar slots need trimmed and shimmed to get good alignment.
The wood density varied to very hard to only slightly hard. The very hard wood was right on the ribs that hold the gear blocks so that is where you would use real hard wood. bottom side Trailing edge sheeting held on with weights Now the real advantage of the jig, I can flip it over and keep everything in place

I also use a adjusto jig and and am interested in your solution. The emt conduit does not hold a consistant level during the build which if not corrected leads to problems you desctibe.
