I was having similar question here: #179331

At the end help me one guy at Bitcoin Pizza Day

  1. Download Bitcoin Core you don't need to sync the blockchain
  2. Open console (⌘ + T on mac)
  3. Insert in for example:

createpsbt '[{"txid" : "903f5ba285e093aef7423fac59bbfcd2979441766bf4a73a622f7e1d606ef17e", "vout" :0}]'    '{"bc1qcmkwdrx3e20e0xsfn2se23wzj9r7dc3t4wd9a3": 0.00000546}'
  1. You get this fancy result: cHNidP8BAFICAAAAAX7xbmAdfi9iOqf0a3ZBlJfS/LtZrD9C966T4IWiWz+QAAAAAAD9////ASICAAAAAAAAFgAUxuzmjNHKn5eaCZqhlUXCkUfm4isAAAAAAAAA
  2. Open Electrum Wallet
  3. In toolbar select Tools>Load transaction>From text
  4. Insert that weird string and hit Load transaction button
  5. 👏 Now you have a transaction that you can sign (this will be disabled, because your wallet doesn't recognize my input)
  6. Click on share> Fo Coinjoin;strip privates > Copy to clipboard
  7. Send it to your peer
  8. He will sign it same way and broadcast it to the network
  9. 🎉 Profit

Now only change my example to yours. Let me know if you need help with that.. For me it was really frustrating to figure it out 🙂

I still haven't found some time to test your instructions, but I see them as the clearest ones and also the closest to what I was asking for. So, yours is the bounty. Thanks a lot for taking the time to share your knowledge.
