Folding tower - proportions of fixed vs hinged pole
By domwild, Section Wind Posted on Mon Sep 18, 2006 at 02:10:53 AM MST
A six meter (20') fixed pole, length from bottom, length to hinge and len. past hinge?

Hi, Will be given a 20' (6m)len. of 2" strong water pipe. Have more 2" pipe and lengths of next size down which fits into the 2" fixed part of the pole. May be called 1.5" pipe in the imperial system. What should be the length from ground to start of hinged (moving) part? Is 2m (6') a good suggestion, so one can put in the locking pin once the thing is erect? Intend to use the smaller gauge pipe from hinge to mill. With a 1.5m prop, which should be off the ground for repairs, I suppose it will be in my power to work out the length of the hinge-to-mill part. Question: If that part is in the next smaller size pipe, will it bend and poss. break as it also has to be quite long?? Are guy wires also recommended for the top (hinged) part of the pole? Thanks. *
