The Newport mirror mountings arrived from the USA today and beautifully made they are.
Well that's my very small contribution to the US economy until I have saved up some more penny's.

After a bit of machining the Z axis 'mock-up' mirror mounting has now been replaced by, what I hope will be the finished part.
Undecided if I should follow Sam's example and anodize the part and dye it black or leave it as it is.

Ano it....It's an unwritten rule. Looking forward to seeing this thing work.

Now that the geometry and dimensions have been established from the MDF 'mock-up' the beam steering fixture can now been constructed from aluminium box section. Not much to look at because the mirrors and Newport mountings are internal to the section.
Still a long way to go but I am getting there, slowly.

A bit more progress - I have started on the focus lens mounting which will be fitted on the moving part of the Z Axis. The lens I will be using is 12mm diameter and made from Zinc Selenide with a focal distance of 40mm. I have still to make and fit the lens retainer sleeve, air inlet barb and output nozzle components etc.

H Barry,

Thanks for the kind words. I can't say that I would recommend doing this yet, as a project it will certainly keep me busy for a few months and I am enjoying every minute but it is a lot more involved than it at first seems. I could write a book on what I have learned so far and I have only really scratched the surface. If the end results are successful then it will all have been worthwhile but at my rate of progress it will be some time before I know for sure.

Heh, no problems here.  I'm barely treading water just finishing my machine;)
