Guess I should have explained what meant by laser equipment- it isn't the laser collimators but a construction laser system I used in boat buiding. This laser draws horizontal and vertical lines on objects for alignment purposes during construction - that's how my structure was aligned.
Yes, I have a Chesire tube and it was used to centre the secondary and collimate.
I have gone ahead and moved the secondary vanes and allowed for the 3.15mm offset as shown by the calculators. Re-collimated to perfection. I will do a test run tonight if possible.
Thanks for the ideas.
