Making a BT50 Tool Holder for SIP Jig Borer Tooling! | Shop Made Tools

Some serious metal removal to transform this scrap piece of material into a shop made BT50 tool holder for our SIP jig borer tooling! In this video we are making a custom BT50 tool holder to suit all of our bigger SIP hydroptic jig borer tooling but mainly so we can use our Wohlhaupter boring and facing head which has a SIP jig borer arbor. The SIP machines have a very unique spindle and all of the jig borer tools have a matching arbour and drive collet to suit it, but that means we can’t use any of the SIP tools in our conventional milling machines…until now! In this video we show the step-by-step process of turning a scrap piece of 4140 round bar into a new BT50 adapter. First, we setup the angle of the lathe compound to match a standard BT50 arbour before rough machining the OD of the round bar. We then drill and tap a hole to suit the drawer bar bolt of the mill before machining the BT50 taper. We then have to setup the angle of the lathe compound to suit the jig borer tooling before machining the taper on the other end of our material and then counter boring that to suit the collar on the jig borer tooling. Next, we use the milling machine to mill out the square for the drive in the tooling and mill out slots for the drive dogs to suit the spindle before finishing off turning the OD to size between centres in the lathe. We test the new shop made BT50 tool holder with our Wohlhaupter UPA-5 SIP boring and facing head before installing it on our BT50 Zayer 3500 bed-style milling machine!
