Racman,
Sound and wood are generally the main influences. I've never constructed a small kit. They've all been big sets and for the most part the concept sets - square shells, all ten inch depth, or 8" depth, or half-toms/bass have just been ideas based on certain ideas I have of sound. I don't think I have played a traditional depth floor tom in more than a decade, save for the one set I put together from component drums while living in Texas. But even then the trad. depth was just one 16x16 off to my left. On my right the floors were hung. Although the green stained set had three 18" depth floors, 14, 16, 18, and a 20x20 on the left, left over from a square shell setup. That has happened with most of my sets. Something from a previous set gets thrown in to the next one.
I still have concept sets I would like to make. One is a set with a 'wood rainbow,' meaning the drums would descend in wood grains light to dark, say English Sycamore to Ebony. But the cost of veneers would be a king's ransom and lots of waste, depending on what veneer supplier I used. Another is a set where the smallest tom would be the deepest, say a 6x12, and the shells would get more shallow as you go around the kit. People think shallow floor toms would be kind of wimpy but not at all. They sound much more musical to me. Deep floor toms can throw off such low frequencies you can barely tell the difference between them, especially playing faster fills. The shallow depths allow the tones of the heads to be a little more prominent. Which was the obvious reason manufacturers went more shallow after the DIYers already went there.
I also wanted to make a stave shell kit out of pine or spruce with grains running vertical. That idea is based around stringed instruments like violins, which use spruce. Very light, very resonant. My first stave snare drum was a 6x12 pine just to see if I could do it. Came out pretty cool and really pops. It's 3/4" thick, though. I made others, figured maple, which are an inch tick. They sound like tanks. Never heard snare drums with such tremendous backbeat. Not my sound, but in a studio, for certain types of music they would be really good.
Most of the times the constraint of funds has kicked in and I worked with what I could afford.
If the economy picks up I may start my own shop and do something fairly unique in the custom market. Has to be because of the saturation of makers. There are so many eye-candy custom makers out there it's incredible. Many, the majority, went under. I got into this in 1991 when the DIY industry was just picking up steam. A bunch of us were on Drummaker.com forum and we just picked apart the subject, and wrote an online book for newbies, etc. Now there are over a dozen parts suppliers of shells and hardware for DIYers. Plenty of wrap suppliers and veneer suppliers. Web sites galore. DVDs. This one is probably the best DIY site for info : http://pdgood.us/drumshed/
If I had the funds to work with I would do some really interesting things. Of course, you never know what you have until you're done, and sometimes you have failures on your hands. But you never know until you try. Most DIYers just stick to conventional set-ups and are very happy with what they end up with. The custom makers try to outdo each other with finishes. Some are so outrageous it's stunning, literally. I really don't know where they can go from here. Now, with computer graphics, the sky is the limit for wraps. As the price comes down and the materials get thinner and stronger more and more players will be using wrapped drums I am certain. For me I like wood grains for the most part because of natural variations. Exotic veneers aren't inexpensive, but it isn't bad when you just make a small kit. The 4 pc has come back as the main contender for so many genres now. Making your own 4 pc maple or birch set is substantially less than purchasing high end manufactured sets. Making a three piece with a manufactured snare even less expensive, though all kinds of metal shells can be purchased now, plus acrylic shells. It's all out there.
I have grown very fond of shallow bass drums. I used to use a 10x26 which played so nicely. Was in the 10" depth kit. My previous set had a 20x22 and I just could not get used to all that extra air sluggishly moving between batter and reso head. The 11 and 12" depths I have now play really nice for me. They sound good on the recordings, too, which was a relief, but I knew they would. The main thing for me was feel. Even with the reso holes and homemade port tubes they still have solid feel and quick response.
Man, I guess I wrote a book here. Sorry about that.
