for those that have erected a mega tree using steel pole's is there a general consensus on what size diameter and thickness is ok to use? im planning a 4m main pole using a portable hole for the base. i was estimating i use a 32NB 4mm thick pipe in the portable hole which should have an Internal diameter of 34.4mm and a 25NB pole to go inside it with a outside diameter of 33.7mm, so the long pole should fit inside the one in the portable hole with 0.7mm to spare im not sure if that is too tight a fit or not, and if a 25NB pole is too small it will have either a 3.2 or 4 mm wall thickness
