Here is what I do for a clean, oil, and adjust
. remove dust, dirt and light tarnish from the instrument body
. check the headcork to make sure it's not leaking air and replace it or wax it as needed
. check and correct the tenons' fit
. disassemble the instrument and unpin the key sections, cleaning out the old oil and replacing it with fresh oil
. shim pads so that the instrument pads seal with a light touch. If your instrument is in bad condition (i.e. needs more than 2 or 3 pads shimmed), I would contact you before I do more shimming. Shimming is time consuming, meticulous work (my polite way of saying a lot of shimming will run up the cost of the COA) but it's what makes the difference between a great playing instrument and a leaky, fuzzy sounding instrument. I do NOT clamp keys to seat the pads to the tone holes.
. I correct all the adjustments
. correct spring tensions
. remove lost motion, correcting key heights
. play test the instrument
. if I find anything else I can correct that will help make your flute play better I will contact you to ask your permission to do the work.
