We have a 1224 threading machine with 914 die and am using it on 4" pipes making BSP taper thread. I have gone thru the owners manual and checked every last detail for setting up the die and machine. It is producing a sort of taper thread but too large for the fittings to engage and when i try to set it on the 4" mark it will not even start the thread. I checked the pipe OD and it seems ok at 4 1/2". The dies i had them sharpened at a tool shop. I have also dismanteled the die and checked for any damage but found none.At this stage i can only say HELP!
