want to create an action which will strip out all channels from a tiff image except R, G and B. i'm not sure that it's possible to do this with an action so i think i may be wasting my time. if anyone knows, please let me know.

hmm
It IS actually possible but its not a very simple method and requires the file to be renamed I can't think off the top of my head if theres a simpler way than this, its an interesting challenge for anyone?
With my method you need to open a new empty file the same size as original - and duplicate the RGB channels into this file - this can be done with copy and paste or calculations or whatever. This new file will be "clean" of any alpha channels or paths, and it will then have to be re-saved with a new name. This process can be embedded in an action easily.

if i copy and paste wouldn't the extra channels just get copied over? i'm just asking this because i'm a photoshop novice, i'll try to implement your method, thanks a lot!

No - Open your channels pallet. You copy and paste each channel seperately
Highlight the red channel in your source document
Select all
Copy
Move to your newly created document (your action will record this as "previous document")
Highlight the red channel in the new document
Paste
Move back to source document
You need to do this same process for the other two channels - green and blue
The whole action will
open a new document based on the size of the old one - then run through the process outlined above for each channel. Then it will save the new file, allowing you to input your new name. and then close the source document.
Make sure you only have 2 documents open during this process - so that the action doesnt become confused.

I can make the action smart enough to open the new document at the same size as the original? Or does it not matter because that gets taken care of with the copy and paste?

I was able to implement the procedure you've outlined, thanks a lot Mark.

----[read-only off]----
my first guess is:
make an action to save your image in some format which doesn't support alpha channels
run it on your images
make a second action to write those stripped images as tiffs luck
