Simple question from a simple guy

def38 · Apr 11, 2018

I am attempting to remove the knob on the rotary headlight switch on my 231 but, I cannot see the set screw to determine the head type; blade, Phillips, hex or whatever. I've tried poking several things into the set screw hole but, nothing turns the set screw.

Help someone.

Thank you.

Get a little bit of playdough from the grandkids and roll into small ball press into the hole and leave it there for a second then very very gently pull out without deforming it you should now be able to see what kind of screw and if it's an Allen key you can compare size with impression

I often use phone camera to take picture to see something like that clearly

I have to agree. Get one of those really bright led flashlights. If you ever own one, you will throw rocks at a conventional flashlight. Some of these new phones have an led flashlight. My phone has one and i've used on several occasions instead of a drop light.

Danno, there is no straight path to the set screw and so any impression will be ruined by the time i get it out of the hole. The access hole to the set screw is about 1/8 " diameter.

My phone camera, while 10 MP, will not have enough light for a detailed image.

As mentioned above is there any chance of getting cell phone camera in place and take picture? Beauty of this is one you have picture you can "zoom" in to look at fastener . The other old trick was to take silicone sealer and place in hole and let it cure (leave yourself a good size handle to pull it out) the problem with this on a 1/8 hole is that if silicone plug breaks in hole you will then need a dentist pick and half hour of playing dentist to get plug out!
