when installing pillar blocks in the bedding process how do you know how long to make the pillars on a remington 700 i am a tool maker and am gonna make them my self i read a artical that said to leave them tong for the bedding process and mill them down after the epoxy has set up also one artical said to use sugical tubeing to hold barrel action to stock another said to just press the action in to epoxy and walk away another said to use the bolts to clamp it down. any help there would be nice too.
