HI Ian,
In my case about 12 years ago I reached the conclusion that it was almost guaranteed that there would be a change in the Fire & Flood work we majored in so I decided to look at adjacent areas that we might grow into as insurance work became scarce. I attended a single day course held by Amir Patwa near London, followed other floor sanders to see what equipment and seals they used, wrote and spoke to some of the main equipment suppliers, hired-in some basic kit until I felt ready to invest in the equipment I needed. I have gradually built-up the equipment to allow us do just about anything to any sort of wood floors. Now I have a 2 man team who move from job to job.
Regards,
Keith
