Alev, Here are some sites that are filled with info: 1)Luthiers Mercantile International aka LMI (lots of info, tools and tips) 2) Stewart MacDonald aka Stewmac (another luthier site with vids, how-tos & tools. 3) DePaule Supply amazing amount of materials and info. 4)Grizzly Industrial.com (inlay material and tools- owner makes guitars so there is a fair sized luthier section. 5) Lumberjocks (you may have to sign up to access search functions) search for "Mother of Pearl inlay" in Forums, projects or classes. 6) YouTube has a ton of inlay vids- I don't have links, but a search will get you more how to's than you'll need. 7) I'd be remiss if I don't toss in Larry Robinson- the most incredible, beautiful inlay work I have ever seen.
I know these are sites mainly for luthier's but the materials, tools and techniques apply to what you want to do. My basic tool kit contains a jewelers fret saw, a deep reach fret saw, a bird's mouth (for cutting materials on), a good light source, a Dremel (or a small router like the Colt). I use a Dremel with a Stewmac Dremel base -expensive but accurate as all get out. The 2 most important items are items we should all have in arm's reach- a good dust mask and eye protection. The pearl dust is toxic and it chips easily so it's wise to be protected.
Hope this helps in some small way....................Wes
