basically not a good idea. You will have problems with maintenance/life span and unless hardwood is used there will be a warping problem. Softwood over a two metre span would have to be fairly thick (75-100 mm x height) to prevent warp and sag and carry the weight of people resting their feet or climbing on it.You will also need an metal shoe to fix the rail to the posts and prevent contact with the ground or vegetation. Either a 6x200 high metal (mild steel) with a galvanised Finnish or a concrete wall 100 mm x height) then you will need to consider drainage if you use concrete Dave Croft ----- Original Message ----- From: "marcus ormerod" <[log in to unmask]> To: <[log in to unmask]> Sent: Monday, September 08, 2003 4:52 PM Subject: FW: Timber Tapping Rail Hi all I received the following query which some of you may be able to help answer. My initial reaction would be that the timber is dependent on the environmental conditions and sustainability policies rather than access related issues which are more about section and height of rail. Regards marcus -----Original Message----- I am presently working on a scheme which require provision of a Timber Tapping Rail along sections of our Promenade. Marcus would you be able to please send me further information such as: * The type of wood commonly used (i.e. name of soft or hardwood ) * A supplier + any related information I shall be grateful for an early reply. ----------End of Message---------- Run by SURFACE for more information on research, consultancy and MSc. in Accessibility and Inclusive Design programme visit www.inclusive-design.it/ Archives for the Accessibuilt discussion list are located at www.jiscmail.ac.uk/lists/accessibuilt.html ----------End of Message---------- Run by SURFACE for more information on research, consultancy and MSc. in Accessibility and Inclusive Design programme visit www.inclusive-design.it/ Archives for the Accessibuilt discussion list are located at www.jiscmail.ac.uk/lists/accessibuilt.html
