Drumset drums: The parts.

Drumset drums are really rather simple devices. They consist of only a few parts see our glossary website Drumbits.com. These are the

• heads, the
• rims, the
• tension rods, the
• lugs and the
• shell.
  

In building a drum, from suppliers you will normally buy

• heads,
• rims,
• tension rods and
• lugs,
• strainer,
• butt and
• vent grommet .
  

• Also, since actually manufacturing a drum shell is a rather advanced process, you will also likely be buying a blank drum shell. 
• Advanced builders do often make their own lugs. In "re-building" an existing drum kit you also can use the old lugs to save money. I rebuilt my Sunlites but I did buy new lugs mostly for looks.

Thus, the main operation in "building" a drum is to take a blank unfinished drum shell and size it, cut bearing edges, finish it with paint/varnish/lacquer/wrap, carefully drill the lug mounting holes and put the whole thing together.

"Drum building" therefore, really only amounts to shell drilling and finishing.
