Ed...... Thanks-I didn't know that. All my instincts would tell me that a flat suface woud be the ideal. Most of the time I don't even fully tighten the ligature- mostly I just use the top screw and maybe half tighten the bottom one. The reed has never let me down by moving.
With regard to the use of feeler guages and paper........ this is fraught with potential difficulties. Can I throw this one into the ring;- just to be sure, I tested this last night and got very good results.
Based on the old engineering technique for establishing a flat surface and for mating two surfaces........ try this.
Smear or dab a thin thin layer of oil based paint ( since mouthpieces tend to be black, then use white or cream paint) on the glass. An area approx 3" by 1" will suffice. Better quality paint is better as it will have a higher pigment density, and you can apply a thinner coat- yes, thin thin thin.
Place the mp down on this painted area- let the barrel end touch down first- and press the table down firmly.
This will do two things...... it will show quite clearly where the curve starts, and also whether the table is flat or hollow.
If you are fussy, repeat the process two or three times and take the average.
I also did a quick test with emulsion paint, and it worked reasonably well, but it is much easier to obtain a thin application smoothly using an oil base.
Try dabbing the paint on with a piece of cloth.
I hope this is of use to you, and if you try it, please let me know the results.
all the best......... H&P
