Use of jeweling tool in adjustment of jewel endshakes

Question

I have a few questions on the use of a (lever-type) jeweling tool in the adjustment of jewel endshakes, as I have never done this before.

1. If the endshake is too much or too little, how do you choose where to adjust the endshake? Do you adjust the endshake on the train bridge, or the main plate, or both? How do you decide which is the best?

2. When inserting the pusher into the spindle of a lever-type jeweling tool, such as a Favourite, is the best practice to take out the entire spindle from the tool frame to insert the pusher? And likewise, take out the entire spindle from the tool frame to remove the pusher? Or is it perfectly ok to insert or remove the pusher when the spindle is still inside the jeweling tool frame. Which way is safer/ best practice.

3. Is there an attachment to the base of the jeweling tool to hold the mainplate or bridges? I don’t seem to see any for sale, new or otherwise. Can I make one?

I consider the interface of the part with adjacent ones, in the escapement for instance you want pallets to interact with  escape teeth at one end of the fork and at the other end fork horn isn't to rub on the roller table.   Once you do move the jewels, you ought to instal the parts back on the mainplate plus its bridge and test if the parts involved are doing what they are suppose to satisfaortrily.
