I want to replace a piece of 15mm round bar with CDS tube of a larger diameter to save weight, I am looking to use 3/4" CDS steel tube, but unsure what wall thickness is required to provide the same strength as the original 15mm diameter round steel bar. Length is 600mm, ends will be TIG...
Hi, I have had some aluminium parts water jet cut for a job, and needed them anodised. I decided to try myself as there will be a slow but steady trickle of these parts to do and it is not economical to have them done professionally with minimum orders.
