AI Thread Summary
Torque recommendations for a 3/4-14 NPSM thread in stainless steel and aluminum are being sought for a work project. Clarification was provided that NPSM refers to straight pipe threads, not tapered like NPT. A resource from Machinery's Handbook was suggested for further information. The original poster plans to conduct tests to establish a final torque specification. Starting figures are needed to guide the testing process.

Hi --

Does anyone have torque recommendations for a 3/4-14 NPSM thread for S.S. and Aluminum? Thanks! Eric

Is that a 3/4 NPT? I can't say that I am familiar with the NPSM call out. Perhaps Q has seen it before. I'll do some looking around.

EDIT: I just found what you're referring to. Straight pipe threads, not tapered. God bless Machinery's Handbook.

Thanks for the help. This is a new thread for a project at work -- and I am going to be performing the testing to determine our final torque recommendation. I just wanted a starting point to have a figure to keep in mind while testing.
 
Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
