Making a BIG Boring Bar | Shop Made Tools

In this video we are making our BIGGEST shop made boring bar! We have a job coming up and none of our boring bars are big enough so we are going to make one. For making this big boring bar we are using a piece of 150mm diameter old ram shaft material off a Hitachi EX1900 excavator cylinder. We show the step by step process starting with turning the OD down to size on the lathe and then lots of milling machine action. The finished boring bar is 125mm (5“ inch) diameter and 1100mm long with a massive 900mm working length! Check out this big boring bar being put to the test! In this video we are using: - Everising H-360HA horizontal bandsaw - Hafco TM-26120G Lathe - BM-63VE Milling machine Join our channel: We upload new videos every Friday at 5pm AEST!
