Ok Brian some more thoughts ............................
Are you wanting to use the camera whilst you are sitting down at the table ?
Yes
I ask this because a table top tripod may mean that you camera is too far in from the table edge and too high to make that possible/easy. If you look at Dan's picture you will see what I mean. This of course can be lessened the smaller the tripod is but smaller equals less sturdy.
A wooden tripod has minimal vibration. I will be able to move the small subjects easily
Tonight I set up my Manfrotto with the extending articulating centre column and positioned things so that I would be able to work whilst sat down. Whilst I would be happy taking single mirror up shots there's too much 'spring' in things I suspect for reliable stacking.
There would be for me.
If it were preferable for me to do my macro whilst sat down at a table without tripod legs sticking out restricting easy movement I would consider some form of bracket attached to the table that allowed a head to be fitted to it.
In the crudest form a piece of 4x2 with a 3/8" long bolt through it into a ball head and the 4x2 screwed or clamped to the table
In my astronomy days I had considered putting in a pier. Something very solid to mount a head to. A four by two would work. Bolt a Manfrotto 410 Junior to it then a focus rail a quick release and I'm off to the races.
As your subjects are going to be small these are easily adjusted/moved around.
