From what I understand verticle panel raising is easier and safer than doing
it with a large 3+" horizontal panel raising bit. Other than making a good
solid tall fence is there any reason to re-consider doing them horizontally?
I have a 2 1/4" bosch router and a table for it.
Plenty of panels are raised on router tables. Slow your router down for the
big cutters. Obviously, with a router you can achieve more than just a
simple 15 degree bevel. Often, that's desirable. Style and rail mating is
easier as well, since the cutters provide proper contours, and actually a
better amount of glue surface - though I'm not sure how much real value that
is. Certainly more is better, but like everything else there is a point of
diminishing returns. Doweled or M/T joinery offer plenty of strength and
stability for the intended purpose. Likewise with the safety aspect.
Properly used, how much more unsafe is a router than a table saw? Lots of
noise from time to time about "3 in whirling cutters", but beyond the
rhetorical value of such statements, the router has an admirable record of
providing safe and efficient woodworking.
Don't know if I really answered your questions...
For 1 1/2 wide areas, you could use vertical, though I find referencing to
a broader table versus the fence easier. I use my jointer hold downs to
both reference and feed that way instead of featherboards or pressure
rollers to reference that I still have to feed around.
Now if you're going for wider detail on the edges, you have to go
I once had a woodworking store salesman tell me that if a 3" bit's
shaft was turning 15,000 RPM, the edge was turning 40,000 RPM. A
planetary geared bit, I guess?
I agree. If treated with the same respect as a table saw, a router
table (or shaper) can be perfectly safe, regardless of the size of the
One big point in favor of doing them horizontally is that it's obviously
easier to hold the panel down flat against a large table than to hold it
perfectly vertical against a relatively tiny fence. I'd think that, at a
minimum, you'd want to make an auxilliary fence a good six inches tall if
you're going to do them vertically.
Sounds to me like a good excuse to buy a shaper...

A less expensive alternative to a shaper might be to use a vertical
router panel-raising bit horizontally; i.e., with a horizontally mounted
router. Your Bosch would have more than enough power in that mode.

I'm sure it's in the books. No need to use the groove, just keep pressure
against the fence. Love my shaper and 5 1/2" cutter, but I'd do this
Either way works. I prefer moving the panels horizontally over the
bit as I find it easier than the vertical method. Whatever way you
choose, make at least two passes for a cleaner cut. A good DC will
help move the chips for a better cut. For safety, think about
guards, featherboards, push blocks, good lighting, clean floor,
ear/eye protection and a clear-thinking brain.
