Completely new here and need some guidance--

Bosch RA1171 router table. I have the Freud shaker bit set 99-762.

What is the standard procedure to set the heights so that each intersect perfectly together? What is the trick here?

Not 100% as I've never done this, but...

I bought some drawer miter lock bits a while back and grabbed the delrin setup blocks to match. Basically you set the bits to a reference sample.

So in your case, run one half so that it looks correct, then switch bits and adjust the bit to mate with your sample. You can then save the sample (s) to setup both bits

to confirm - the first half doesnt have to be perfectly centered or anything?
Does it matter, or is it easier to do the rails vs stiles first?

So theres no technical way to do it by measuring -- just run one through then creep up on the other with a test piece (and save that sample?)

Since you can change the groove location to suit your needs you generally start there and set everything else up to match. How you do that depends on what you have to measure. Most people will just use trial and error after setting it close to a known good sample.

Or use a height gauge, but you still need to know the height you want (which isn't provided)

Once you get it set up for height you want, run a relatively large and square piece of stock same thickness as your frames through the rail profile and use it as a backer to cut your rails. Will help keep the short ends square to face on fence and prevent tearout.

Start with the thickness of the stock(3/4" or 13/16"), what is your panel thickness(1/4"), how much material is required to support the panel on the back(1/4" or more), how much reveal is desired on the front. Set the rail bit to what you want, then set the stile bit to match that cut. Make some setup pieces from the stock you cut so you have a guide for the next time.

On the (right) tongue piece — the instructions say you can get a tongue and groove of 7/32” but when I look at the tongue bit, there’s no extra shims to remove.
The bearing has to run on something and in the photo the thicker one on the top is welded in and isn’t removable so I’m lost on how to achieve a thinner cut.

What am I missing here?

In all seriousness with that type bit, the best may be to have a table for each and never move while making your pieces and extras.

Do you have the set?

Why do you want to go thinner?

Looks to me like the bit on the left (which cuts the groove) is set to do 7/32 already, and I assume the right but (for the tongue) matches.

What size stock are you running, 3/4?
