Sinktube over MHS and activation box one problems

[Luke Halcyon]

so ive seen plenty of sabers with sink tube over MHS to like obi wan's first saber, My question is which type of sink tube is it that they are using? and another question that i cant seem to get answered is with activation box style 1 how would you mount the switch out the side securely? a picture would be nice or something super descriptive im visual like that.
