Testing the BIG Boring Bar, Shop Made Tools

In this video we are testing our BIGGEST shop made boring bar for the first time Its a 125mm x 1100mm long bar made to take a 25mm tool and we want to test it to see how it performs with different inserts, feeds and speeds on the lathe. We are test boring a piece of honed cylinder tube which is not the nicest to machine so will be a good test for what the boring bar can do. This bar is made from an old Hitachi EX1900 cylinder ram shaft and if you missed the video of us making the boring bar check it out here: In this video we are using: LZMT CW6280D Lathe In this video we are using: TM26120G Centre Lathe WIA 500i Weldmatic welder HMP150T Hydraulic press BM63VE Milling machine
