My solution for an angle drill.broken 1/4”extension. Put a square drive male in the lathe and turned the female part to 3/8”. Threaded it to fine thread and away i went. The threads actually appear in the corners, but when in the chuck they are supported. A bit of locktite and it is the ticket. 3E8EA79E-B6E4-4AE9-AB1E-E56E5DF8D72D.jpegDADB0AD0-DF56-4AA7-8F5C-398CBDF6A29B.jpeg65B67C17-C6DD-4EE5-9B23-180181DC97B6.jpeg
