First time on this forum. I need to install about 100' of 3" schedule 40 conduit so the electric coop will bury the power line from the road to my house. I'll be putting 90° sweeps at both ends & an elbow in the middle. These conduits are 10' long & I'm worried about joining them. The're belled at one end but it's a very tight fit & I need advice on how to join them. Do I just put a 2x4 over the end and pound the heck out of them? How about the sweeps & elbow? Any advice on this project is greatly appreciated! Thanks
