I often like to ask questions I presume to be obvious to most yet somehow they aren’t so obvious to me.
Spin Indexers and holding/clamping…
Every spin indexer i’ve ever seen online, including the one I have (below), has at most 2 machined edges (front/back) and no clamping slots/holes.
As you can see from my pics, holding on the machined edges is not possible because of the front disc and port access to the turning handle and holding side to side on unmachined surfaces will not only not be square, it will crush the powder coat finish.
So what am I missing? Is the owner expected to machine the surfaces or cut slots to meet their own needs? I just don’t see why only 2 sides are machined and not all.
