CMS vs. Miter Sled

I do my miters on a miter saw for anything less than 12” in width. Over this width you need to use another type of saw- a table or radial arm saw or hand saw for those who possess good hand skills. The miter sled, once it is set, is usually dead on with respect to miters but it is largely a matter of personal preference. I do not have a miter sled and make miter joints routinely with my miter saw.

Randy, It all depends on how accurate you need your cuts to be. I do some segmented turnings and the odd octagonal bird feeder.
The CMS is just find to things like a bird feeder but for segments you need a sled so you can really sneak up on the angles. The same can be said for any fine furniture joints that will demand a 45° joint or less.
The other big factor is accuracy on the sliders on a CMS if you have one built this way.
There is a lot of SCMS offerings out there yet I see no stats on the sccuracy of the cut as yet.
I have an Hitachi 12” SCMS and I am satisfied with the accuracy for building cupboards and shelves etc but I still favor my table saw and a precision sled for things that have to be dead on.
(it seems a bit safer too)
