my foot joint had some wobble when connected to the body, so I used an expander to open up the tenon. Polished it off with some paraffin wax and cleaned out with denatured alcohol. because I have a nickel plated flute, I had to buff the instrument to clean it up. I had buffed with yellow for the body. before- double G. After - foot joint to the key buffer for the keys double g before halfway finished! time to start padding!
