The piccolo that I am using is stiff to put together, someone said that you are supposed to put a type of grease on the cork...?

Any recommendations?

Cork Grease? You can get it for clarinets.... I suppose it'd work for picc. too!

yep thats right - im guessing your picc didnt come with the tiny container of grease? Clarinet stuff would work just as well. But only use a tiny amount!

clarient cork grease you can get in a music shop...........onyl costs about £1
