Ok well first i took like a block of wood (i hada saw it off a long piece) that was as long as i wanted the pipe to be... and then I took a hand drill (stationary drill would be better but mine doesnt work) and I drilled a hole as long as i wanted it to be... and u gotta take the bit out and like see how far it went in and then drill a hole from the top of the block so that it connected to the hole I made before. Then, I used a knife to carve it to the shape I wanted. I just kinda made it smaller and rounder...make sure you make the bottom flat so that you can put it down and pack it without it spilling. Then, I found a (i dunno what there called...they are for wrenches and they are different sizes and stuff... Its for those wrenches u use for bolts) and I found the right size. If it doesnt fit pefectly you can use hot glue (not to much) to make it airtight... and then if you dont want your weed to go in your mouth u gotta cut a tiny square out of a pop can or something (or find a screen if u can) and poke little holes in it and then shove it down into the bowl hole. OH yeah and before making the bowl, SAND. ALOT. wiht sandpaper. It not only makes it look better, it keeps u from getting splinters n stuff. Sand inside if you can, too. Make sure you blow through the pipe to get all the shit out that u sanded off. Sorry if this is complicated or anything just ask me if your confused...
