i cant seem to get that perfect hop trub cone that i see in so many homebrew pictures. i have a keggle with a copper elbow going to the outside wall. i use a counterflow chiller and i whirlpool. by the time the wort level gets low the pile of crap ends up spreading out and turning to soup. what am i doing wrong? thanks for any advice :)

Well not for nothing but that's the domain of the cool kids.
As an aside one never knows how long the photographers in questions let it set before draining and snapping the pics. Maybe they cheated a little for the visual effect? Ya know - - Like the Red Lobster's glorious beautiful pictures of what looks like flawless delicious food in the TV ads and when you get there, the food looks (and tastes) like something rejected by starving Somalis?

How long does it take to go there?
You mean you are porting through the kettle wall using a tube with an elbow on it?
Suddenly the old school siphon seems like a solution, one can move it around.
Anyway, take soe time to contemplate the opening of that elbow. You want to think about how high above the trub line you want it to sit. It's going to suck some goo into the primary and through your chiller, but the goal is to minimize that.

As an aside flow volume is a really big deal in trub collection (or avoiding it).
If you are draining through a large diameter pipe the flow will be great and it will - of a certainty - capture and carry trub. A smaller diameter opening in the port will produce a lower flow dynamic and will take up less trub.

Yes, that's because it just doesn't like you. Try singing in Italian. I hear that helps.

Have you considered tilting the kettle a scosh when you whirlfoc to get the trub into a more manageable and smaller space? Maybe giving it a little more time to settle out?
The down side of tilting the kettle is of course that your fixed point drain won't get all the wort out.

However, you really do have to sacrifice some wort to the god of the trub. He gets royally pissed if he's denied his share.

Try experimenting with the amount of kettle finings you use. Too much can cause the break material to be fluffy and not very dense. It forms a cone, but the cone falls apart easily. Too little and you get fine particles that don't form or hold a very good cone. Most homebrewers use too much rather than too little.

Just the right amount (which can vary from brew to brew - sorry) will give a quite "solid" cone thats almost jelly like in that it will wobble when you disturb it, but not break up.

The other trick - is to really slow down your rate of run-off as soon as the cone starts to break the surface - if you drain the wort so quickly that the liquid level drops faster than liquid can drain from the cone, the cone will be pulled apart. If you slow down, it just sort of settles as the liquid slowly drains out of it.

Hope that helps

I believe that one Whilrfloc tabs are not designed for home brewers but rather for commercial size flocculation I only use half a tab in 5 gallons or wort and I think it's probably too much.

From the MoreBeer! website:
Note: One Whirlfloc tablet is good for 10-15 gallons of wort. We suggest using half a tablet for 5 gallon batches for most beers.

1/2 a whirlfloc is the correct amount for 5 gallons.

1/2 a whirlfloc tablet is the general rule of thumb amount that is the oft recommended amount for 5 G.. but seeing as a whole one is what is recommended to use for 10-15G... that 1/2 a one might be as much as 50% off.

So - I reiterate - experimenting with the amount is a good thing to do. The "recommended" dose is so broad that the best you could say about it is that it's not totally wrong. If the OP is having trouble with poor adhesion in his trub cone... then suspect No1 is the amount of kettle finings used (after the run-off rate)
