It could be several different thread sizes, but your smith can match it,Does somebody know the thread size for this Brake??
thanks from Europe
That´s the Problem, the size of thread is not common in Europe so i have to find out which size of cutting tool i need to buy!!
Is it a 5/8 x 24 tpi?? that means 15.88 x 1,05 thread size in millimeter??
Thanks, understood!! I already got the right plate for the barrel tenon!! so i can use the same for the brake too, because it has the same angle of 60°!! .625 is what i measured inside the brake, so i can start chambering and fitting barrel!You don't need to buy anything. Your gunsmith or machinist will use the same thread cutting tool he uses to cut everything from 1/4-28 to 1.062-16 tpi. A thread gauge will confirm the threads per inch. Most likely 5/8-24. Measure the thread relief inside the brake and it should be around .625" - .630" Cut the tennon .625" Set the lathe to 24 tpi and start cutting. Don't even think of trying to get a metric thread to fit. Once fitted concentric to the last 2" of the bore it will then need bored out to .020" over you bullet diameter. If none of this makes sense, take it to someone that it does.
