For the cork and pads, kudos must go to Hammy Hamilton for his recent “Wooden Flute Maintenance” DVD. The tools needed for these jobs are on this video, and most of us can do this at home and it is a satisfying piece of work when completed.
It is an excellent resource that made it possible for me to do this work out here in the hinterlands of Montana. If you are a wooden flute player, this DVD is a must have. You will learn a lot about wooden flutes, even if you do not intend to perform these repairs.
The DVD is now being offered on Ebay.
Many other sorts of repairs and maintenance are included in this handy DVD. The hands-on directions are very easy to follow, even for the manually challenged. Just one repair job will pay for the DVD. You can do a search for 320355283711 or find it under Wooden Flute Maintenance DVD-ROM
