From my understanding you have 4 parts, 3 of which have a taper of 20 degrees included angle. One of these parts is supplied as is and has a huge tolerance (20 thou). If this tolerance is a tapeered part then it seems you do have a problem.
The only way you can manage this is to match each...

There are printed tables available of Rockwell-Brinell conversions and have existed for many years. Most steel suppiers will furnish you with a hard copy of their literature. Macready steels comes to mind.
You don't say if it is an internal thread or an external thread. An external thread has a large tolerence on the major diameter. But as the gentleman said earlier this is not a clipped 11/16 UN thread, it is a bastard thread. It is 1.6 thou less than a 17 mm thread but is not metric because of...
I notice there is an American pump manufacturer called Worthington Pumpss, is that the pump you have? I notice you have increased the prime mover HP by 40%. Did your flow improve from the original motors?
Surely you will contact the pump manufacturer and ask for specifications for these pumps...
Changing impellers on multi stage pumps can be an expensive business and take weeks to complete. If they are single stage pums there is still a lot of work to be done.
Condider buying an extra pump to increase the flow if possible. Alternatively you may strip one of the pumps and check up on...
If the part is completed using two separate setting you still have the problem of blending in the two separate cuts, but if it is not critical this may suffice. Generally speaking operations should be completed as far as is practicable in the same setting.
Hence when turning a coupling for...
If the material is difficult to machine (say 316 stainless ) then drill last as the holes can be hard on the inserts and your cost go up. If there is risk of movement in sizes you may have to rough out first and then final machine toleranced. sizes.
If you have to machine a long and difficult...
Then you have to buy propriety side clamps that press into the sides of the work-piece and exert a downward pressure, you can also design them yourself, it's old technology.
If you have the room you can make up blocks to clamp to the table and use an M20 tapped hole with a bolt. Drill the...
160 C is not that hot, 316 is the salt water standard steel. If you really need salt water protection and high temperatures you will have to look at a Nickle based products and they are much more expensive.

Even with grinding he still has to work out how to hold the job down on the table if the material is non-magnetic. He can sub-contract the job out but I guessed he is wanting to know how to do it if it is to be done in-house.
You have to make a crimping tool in two halves as with a scissors. You will need to design the tool carefully and experiment a little to get it right making allowances for how much give is in the material. It's not my field but I have see toolmakers do it and that is something they specialise in.
If you cannot obtain the manufacturers part then you only recourse is to make one. It won't be cheap but a good precision or toolmaking company will make a thread connection for you and coat it with anti galling or T(ic) coating so that it will not gall. I would expect a company to charge you...
