Inspired by Monkey Spanker's recent homemade sticks thread I thought I'd share my homemade tumbler which I've just finished making from an old printer. Please note, I haven't actually used it yet but plan to update the thread or the tumbler as required. I'll post photos below which are self explanatory. The idea's not mine, I took it from YouTube but I have made my own adjustments. The build cost me 50p for the mdf which I got from the off-cuts section at B&Q. The printer I picked up at the local skip and the waterproof tub is a fitness supplement container I pilfered from my brother. The 12v battery is off my pigeon magnet but it now runs off an old 16v laptop plug which gives it proper grunt. I'll let you know how I get on.
