Another heads up on your CNC millwork. I see you are cutting the shelf out too. While this isn't a bad thing, I would be very careful on your depth using the CNC having a sharp 90 degree transition from the shelf to the strike plate section is not a good thing. Those risers can crack at the belly side of the shelf or even the back side unless that transition has a slight radius.  I would highly recommend cutting it an 1/8" shy of the finished depth cutting that shelf, then use your random orbital sander to finish shaping it. It will be much stronger getting rid of that sharp 90 degree cut line.   

Food for thought.


Another thought might be using a cutter bit with a slight chamfer at the tip, or a tiny round over. But I don't know how that would effect your other machine work...

Ya I always take a round file to the edge but that's a good idea, I can swith the bit to a bull nose when I go to cut the shelf to already start the rounding.

Turned out okay for the first one. I need to work on the shape as distance in the middle isn't very even.

What kind of woods are those?    

[Watsonjay]

The brown is katalox and the middle is spectraply

That's a lot of work hand fitting footings of that shape. Hopefully you are not forcing those joints together with clamps. That can come back to haunt you down the road.  Just saying....   But they look pretty cool.

Once you get set up with a pattern sander, it takes all the sanding and fitting time out of footed risers. It's well worth the investment. .02 cents worth.

It isn't that bad with the cnc. It is 1/8" bit so it creates the 1/8" gap. I grabbed 2x 1/16" materials. Warmed them up a little for more flexibility glued and clamped. Not really that much pressure as there is the perfect space for it.
