Repairing brass dies for pasta extruder
I am not a machinist but hoping for some help with your expertise…I have these brass dies that were altered and then not able to withstand the pressure of the machine and the brass on the front half of the die split wrecking the screw threads. I’m not sure of the exact working pressure but it seems like equivalent machines might run 32-50bar. I would like to retap the existing holes and use brass screws but am unsure of what diameter and thread type would be best to use - I need the front of the die to remain flat so I either put screws in from the back (original configuration) or anything going in through the front needs to be countersunk. Any suggestions are welcome. Die measurements are as such: 9.5cm diameter where pressure is applied, 1.95cm back half (where most pressure is absorbed), 1.16cm front half.
