There are several other sites that sale componets or kits for box calls. I can' t think of them right now, but one is Peyton Putters.

You can also go to... http://www.customcalls.com He has links for phone numbers and e-mail addys for people who sale componets such as slate, wood and etc. You can also keep your eye on ebay and for the saler Hidden-Hollow. He also sales componets such as pots, slate, strikers, etc.....

As for making them. I just finished three calls. Two Sassafras Slate over Glass and one Walnut slate. The two sassafras calls sound pretty darn good. I just followed the directions from Customsawing.com. I did sand the wood down to what I wanted, by getting rid of the sharp corners and the tool marks and then buffing the wood with fine steel wool to raise the grain. However, the walnut call was a disaster! The wood was beautiful however the pot was too deep for just slate. The sound was nasty!!! I should have put some sort of soundboard inbetween the slate and the pot such as glass or some sort of metal or acrylic. I used Minwax polycrilic spray for a protective finish, using three coats and buffing with steel wool between each.

The stirkers were very easy. I again ordered the ash tops from Custom sawing and some 5/16" dowel rods in black walnut. I sanded the rods and the top and then again steel wooled the top to raise the grain. I then applied a light coat of Minwax " golden oak" on the top to try and match the finished sassafras. I also applied polycrilic on this, three coats. I glued the dowel rod into the predrilled top and let it sit. After it dries you just figure how long you want it approximately and cut the dowel rod. I then went through the process of finding the exact length for each call by finishing the tip and trying to call. I ended up cutting one striker about three times and the other twice to get the desired sound/pitch I wanted.
