محول، مغزل 3 بوصات إلى ظرف مخرطة 5 بوصات

I mounted it on my lathe flange and it fits perfectly, requiring just light cleanup on the unfinished side. The partially machined approach saved a good bit of time compared to starting from raw stock.

Machined the mounting face true in about 20 minutes, and the fully finished lathe flange side seated perfectly on my spindle with zero runout. Now my 5" chuck swaps onto the 3" spindle without any adapter wobble. Just what I needed for a clean setup.

The machining on the lathe flange side is clean and precise, so it mounted up without any fuss. I just wish the chuck side came with a pilot hole to help with initial alignment, but it's still a solid base to work from.
