I moved my earlier writeup to this spot.
I needed to cut some 1/32" grooves for stringing on legs of a federal style piece. This involves curves at the top and bottoms, and I was seeking a radius cutter shown in an article, which I never found. I have the Dremel plunge base for the rotary tool, but it is a disappointment, being too flimsy and creating much angst in use. In researching, I looked into the Stewmac plunge base, and the Veritas device. I decided on the Veritas for several reasons; one being bang for buck - the Veritas set includes accessories to enable many more functions, for about the same price as the basic Stewmac base and edge guide - $199.
The base is very sturdy aluminum with zero sloppiness in the plunge function. The fence attaches to the base with very nice knurled screws (all the screws are nicely knurled; I like that). Once the lower piece is attached, the screws visible facing you in the photo can be removed and replaced with a pair with half-round heads (visible in the box) for following an outside curve. There is a 1/4" pin for a center for circle routing, as well as a sharp pin. The aluminum disc is a pivot that can be attached to the workpiece with double face tape when the surface cannot be subjected to damage. All these fit into a hole in the triangular adapter shown in the box.
Now that I have used it for the cellarette, I like it even better. It is rock solid. I was using some 1 mm carbide bits for the 1/32" stringing, which are really brittle - I broke 3, but had purchased a pack of 10 - and any sloppiness would have resulted in a lot of breaks.
Note that I had a problem; a tiny retaining ring on the adjustment screw on the precision adjuster was missing, thus it would only move in one direction. An email to Lee Valley and I had the ring by Fed Ex in 2 days.
This is one of those instances where a new tool is like Christmas for a 6 year old.
