Thankyou CCD.
I posted the question some time ago and in that time have acheived the TS2 standard. (In fact we have our second full audit, not counting the initial book audit, booked for next week.)
The maps I finally settled on and which have been approved by the BSI, are as attached. They are written using "smartdraw version 7". You can get a free reader download on the web.
Although the attachments look simplistic, in actual fact I find that they take just as long to raise as your example because you have to identify the key steps just the same and the definitions you use have to briefly convey each indivual process. These maps are then hyper-linked & supported with work instructions, which can be process maps, photographs or written word, in addition to documentation such as COSHH and H & S info and finally the forms required by the operator.
I discovered through a training course that the standard expects flow maps that show the process. (The key was the fact that the standard asked you to identify the process steps only. Our trainer explained, over lunch, that this was the most important thing.) You have to show a link to the next step but you do not have to define how you do it. The more you define the more an auditor has to audit.
This is now established by the auditor, who identifies the process itself through the documentation trail. For example - our auditor now looks in much greater depth at our training records and interviews more operatives to verify that they are fully conversant with the process. (Much greater depth than when he auditted our ISO9000:2000 & QS9000 where he seemed to concentrate on documented records, which is still a large part of the audit).
I wish you the very best of luck in your quest to gain the standard and thank you for the info that you provided.

As a company we have definately benifitted from the change in style. The guys actually take notice of the maps and the pictorial WI's. It's worth the effort.
Best regards,
