My first version of the outer "Thick" washer was made from approx 6mm thick steel with a slight recess on the inner face which enabled it to locate inside the clutch but not too deep so as to bottom out on the end of the crank. Two holes are drilled in the washer, one centrally for the securing cap head bolt and another that is drilled "off-centre" in line with the centre of the key-way. This "off-set" one is tapped for a 5mm or 6mm thread and a short 10mm long ish cap head bolt locked in place. The protruding thread on the inside is then filed square such that it fits snugly in the end of the key-way in the crank & clutch thus preventing the washer to rotate about the central bolt. Lock wire holes are then drilled across the head of both the central locking bolt & the 5 or 6mm bolt now secured in the washer.

My second version was very similar but instead of using a 5mm or 6mm cap head bolt, I actually welded a piece of the key-way steel through the washer. On the inner face of the washer it was cut such that it just touched the end of the piece of key-steel that is used to lock the clutch to the crank. On the outer side it protruded about 6mm and a lock wire hole was drilled across it.

A further addition if you require is to fit an anti-vibration washer under the head of the central securing bolt.

Hope you have been able to follow my rambling.

If you need a photo of my Mk1 version, please let me know. Unfortunately I sold all the Mk2's before I had a chance to take any photos.
