I am a apprentice carpenter and I am working on a house where a back carrying beam is rotted and I want to reinforce it with a 2 x 8 but run into problems cause the house refuses to lift with bottle jacks. It goes up a bit but not enough for the 2 x 8 to clear the main beam. I have tried different ways to get the 2 x8 along side that carrying beam but it just won't go. Any advice with this will be greatly appreciated.
