Nick, I think what you made is cool and certainly should be able to function well for you. What I was speaking of in your earlier thread on a similar subject was more like this [please view attached] S-S-T simply refers to Stair Stringer Template. The solid color represents your template material (I recommend 1/2" thick MDF) and the cutout needs to be your actual stair dimensions + 1/8" in all directions. If I were doing this (and I've done this many times) I would use a plunge router, 1/2" diameter bit and 3/4" guide bushing.
I would have the markings (in pencil or Sharpie) on the stringer [workpiece] and simply position the template atop where the routing should take place.
This template works for both sides via flip-flop. Clamp as required, F-Style Clamps work well for this - especially when they are positioned bar-downward and out of the travel path of the router.
My recommendation of 1/2" bit + 3/4" bushing assumes all wooden members are to be MORE than 1/2" thick. Depending on wood species you are using, sequential passes of 1/8" to 1/4" should work well for you.
Nick my friend, if this is something you would like to pursue; I am glad to make you an AutoCAD drawing for your template.
Necessary information will be: Stringer dimensions (L x W x T), Tread dimensions, Riser dimensions and Nosing requirements
In stairs such as this - if the underside is not visible, I would recommend an ATR under the nosing intersection about every 3 or 4 feet along the pitch of the stringer(s). The All Thread Rod enables you to keep slight horizontal compression on the treads and risers. I hope this helps, You know how to get-in-touch with me if anything else is needed from me.
