hey you didnt say bend the pins
now that is getting tougher.
i was just trying to help with the filing
the INCAN forum would be best place for the bulb socket info.
the fiberglass dremmel thing are bigger, and dont fall apart , the ones that come in the kits will blow off in your face, but they are much thinner and smoother for thin cuts. they call them "cut-off wheels" we use them for everything imaginable.
the sockets usually use a glancing flat conductor internally, a wide strip of metal \\ that attempts to make as much contact down one or 2 sides of the pin \o\, that means you MIGHT be able to expand the hole in the sockets top insulator alone to expand the size of pin that would go in.
and, depending on the shape and direction of the internal conductor, because some are Ued where the pin lands, you might be able to make a slide slot in the top insulator plate, that would fit more bulbs.
we had to do that with an old projector with obsolete bulb.
i observe the direction of the connections through the tiny hole there, then shove a drill in and slide it sideways cutting a path, in the same direction that conductor is. but i had "nothing to lose"
but i dont do hotwires , just video lights and stuff, so i dont know the bulb item, or the socket item your using, so i probably shouldnt have tried to answer the question.
what to pull the bulb out with? Paper towel wrap, or use the plastic foam that is around the new bulb. what to Hold it with, same thing. cause human skin oils and acids bad for hot bulbs. terlit paper and snot nose paper all can have oils permiated in them, paper towel is usually clean.
i could get it into a vice, with rubber jaws (still wrapped), but i wouldnt risk it
then what about alignment? if a slide slot or a bent pin offset the centering , that would suck.
