I am in USA and I have steel supplier with many options for tubing at 1.050" OD. I can’t seem to find any information on whether this will work or not. 25.4mm should be 1.000". 1.050" converts to 26.67mm. I have seen some posts where the 1.050" size is mentioned but where it may be acceptable. I tried searching this forum but it always says no results found, regardless of what I search for. Thanks for your help!
