Hello all. I really don't know if this is the correct place to post but I've been google'n for a good hour and I can't find anything like this. I found lots of arbors but none like the photo below:



I want to setup a rig to use a saw arbor attached to a pulley like pictured above. Are there anything like it or do I have to custom make it? I was thinking buying an arbor and extending it, adding bearings on both ends, then attaching the pulley. Any insight would be great!
