To properly use a lathe crotch center to drill an oil hole in a bushing, you would mount the crotch center in the __________.

🔍 Key Concepts

• Lathe center locations: Know where work-supporting centers are normally mounted on an engine lathe • Purpose of a crotch center: It supports hollow or tubular work so a drill or tool can access the center area • Oil-hole drilling setup: How you position a bushing so you can drill down its axis while it is properly supported

💭 Think About

• Which part of the lathe is normally used to support the free end of the work with a center that can be advanced into the work? • If you are drilling an oil hole in a bushing, which end of the lathe would typically hold the drill and which would support the workpiece? • Would a crotch center normally rotate with the spindle, or would it more likely be a stationary support that can be fed into the work?

✅ Before You Answer

• Identify which components of the lathe are for holding and driving the work (connected to the spindle) versus supporting and feeding centers into the work • Confirm where standard lathe centers are usually mounted when turning between centers • Make sure the position you choose allows a drill to reach the center of a hollow bushing while it is properly supported
