I am going to be spinning a horizontial panel raising bit (with a back
cutter) in my shaper with a router collet. It is part of a door set
and is 3 1/4" across. It has three wings, the safety type with
infilled sections between the cutters, In the past I always cut rustic
type raised panels on the TS with a standing jig, used flat panels or
just purchased doors premade.
I am cutting pine panels and they are actually not glue-ups but wide
3/4" boards, a bunch of em.
I plan to do the panels in two passes.
I'll setup the fence so it is aligned with the bearing. Then before I
run the first pass I'll attach some 1/8" ply to the face of the fence.
Then I'll run all 4 sides of all panels cutting the raised profile
almost complete depth. Then I'll remove the ply and run all the panels
back through, trimming of the last 1/8" for a clean finish.
Do you think I can hog out that much on the first pass? I'm thinking
maybe make my daughter try to push through the first piece while I
stand across the shop, ready to call 911.

Yeah, very familiar with cutting cross grain first and I will use some
backing to avoid blow-out.
I prefer to use spacers. I can do a test piece and dial in the final
location of the fence and lock it down. I do this on lots of ops
because I do long runs, 30-50 pieces and might need to do 20 complete,
then come back and do the next 20, etc.

You scare the hell out of me, even if you limit the shaper RPM to
8,000 RPM.
I'd plan on at least 3, probably 4 passes including final clean up
pass.
If you want a dose of reality, do the math on a 3-1/4" dia bit
swinging at 8,000 RPM.
Over loading a cutter tip with to deep a cut under those conditions
scary.
Just my $0.02 worth.

Yeah, I look forward to getting some power feeders. I am trying to
spin up a full time bidness but still do it all myself, on the side,
in the garage. Once I hit real production it will soon be onto the 3
headed shaper with a feeder and another feeder for the TS, if not a
gang saw.

This is why I was asking. I've seen several instructions that say to
do one big pass and a second clean up pass. I was a bit worried about
it.
Yes, I'll drop to the lowest speed.
I guess I'll do multiple passes.

The final depth of your cut will be 1 15/16".
> I plan to do the panels in two passes.
At least four passes would be better - and the speed should be about
8000 rpm.

In the past, for the first cut I've attached, 1/2" ply. Then, I used
1/4" ply, a piece of Formica laminate (~ 1/16") - and a final clean
pass without a spacer. That gave me good results.
Cut the end grain first on each pass.

You can, but not for a good outcome.

Yeah, but this has a back cutter so I need to go straight into the
edge because I am cutting both faces at once, so I can't come up from
one side.
Oh yeah, I for got about that the back cutter, I knew there was a reason I
prefer not to have a back cutter.

Why not do the first pass on the saw? Be a lot safer.

Regardless of the species, it is always best to take a little at a time. 3-6
passes sometimes.
As you make your passes, always cut the cross-grain first. Sometimes, it is
good to put a sacrificial piece of lumber at the end of the cut to prevent
tear-out.
Even with a powerfeed, taking out too much at one time is hard on your
cutters (or bits). Your risk of tearout is also greater with big bites. If
you are not using a feeder, you will have greater control with small bites.
Always use a jig to hold the workpiece firmly down while cutting smaller
pieces. (or use your miter gauge)
Remember that if you are using a back cutter, that you must keep the
workpiece from coming up and changing the edge thickness with successive
cuts. (this is not a critical point)
If you are using a router table, it seems that you could move the fence
instead of using spacers.. though I have done so myself in weird cases. (I
am really unqualified to say anything about router tables, since I never
owned one... I may make one some day).
Make sure that your bit is sharp and you will get a smoother cut.
Lew Hodgett has some good advice.
Have a good day. woodstuff

The only thing I might add is that with softer woods, incl. pine, it is
always good
to not slow down so you don't burn the panels. You can go slowly on all but
the last
cut, but then do that last little bit with a good even speed. You probably
already knew this much. On hardwoods, it is harder to burn sometimes.
IMHO.
But I've been spoiled by a power feeders on my sticking and panel-raising
machines. Before that, I shoved it all through by hand on only one old
Delta shaper.
Also, in recent years, I started planing down my panels to 5/8" and not
using a back cutter. This is not necessarily the best way, but it works.
For flat panel doors, I started raising the panel and inserting the raised
side on the backside (only on high-end jobs). I did a kitchen in QS White
oak and put in plywood panels and it looked crappy to me; I won't do that
again.
I hope your work turns out well.

I method in a routher table with a the larger Triton router is to make 3~4
passes. However I raise the blade, IMHO less stress is applied to the tip
of the cutter.

You _do_ have on your welder's leathers and the 6-ply aramid-belted
apron when you're spinnin' that thing, right? Good.
