Additionally, I have been watching a very good video on producing a template for the closed carriage stringer and am still a little fuzzy on a few points....
1. if you are using your tread and riser and wedge material as a form for your master template then you must be using a top-bearing trimmer bit, yes?
2. That being the case, if you use a 7deg dovetail bit with the finished template your tread openings are going to be mis-sized aren't they?
3. I would rather use a guide bushing so my dovetail can move without a bearing. Does that mean the "use your stair material" way of doing things is out?
4. Bought the 1617 evstb (should've bought the PK).
5. Lastly, if it is advisable to remove the bulk of the material in your dado before using the 7deg dovetail bit what is the order of operations? It seems simplest to set up 2 routers, one with a spiral upcut for bulk removal and the other with the 7deg dovetail and do all the routing for each step before moving the template. Does this make sense or am I making it overly complicated?
