Looking for a method to flatten the ends of 3/4" thin wall EMT without splitting the sides of the fold. I have a suitable bench vise and appropriately sized hammers. I do not have access to a press. I understand it's helpful to position the weld accordingly but the weld is not visible in this EMT. Both the bench vice and hammers flatten the EMT easily but split the sides more often than not. Any advice would be greatly appreciated. There must be a trick that someone knows?
