can't see the picture. but the reason why i do this is because i see somebody else tied his torch to a vertical metal stick with a rope. i feel it's funny when i see that picture, not only that method isn't solid, but the torch is easy to get to spend, and at the same time it's hard to adjust the angle. so i work this structure out at last free weekend, it's easy to adjust tha angle as a table lamp and won't hurt the torch,at the same time wood products are more friendly, isn't it?
( iam a R & D engineer, this work can't be more easy for me)
