Something is making a screach sound like a nail or screw rubbing on the barrel how can find it?

Sounds like the drive hammer might be jammed. Make sure barrel and drive hammer are lubricated and there are no obstructions in the barrel.

are you using the correct nails for your nailer? some nailers use a 20 degree slant others dont. If slanted nails it could be that they are in backwards. If you use slanted and your gun requires straight nail strips this could be the reason as well.

Hi,
Here is a tip that I wrote about dryers and noises...

Asker's Testimonial " This should give me an ida of what to look for once I open er up

sounds like the bearings

your drum glides/rollers are defective on the front edge of dryer where the drum rests,sounds most like the glides are glazed,not roller bearings but check it could be either

You either ripped your voice coil, or you have something jumping around inside (Screw, nail, etc.). You can tell of a blown speaker by pressing straight in, and if you hear a rubbing noise, then your speaker has disconnected from your voice coil. Mickey mouse jobs include Krazy Glue, but It's touch and go

hi buddy you obviosly havent put it back together propally restrip it down and check for the following 2 circlips in either side of the piston where the wrist pin is also check the barrel is smooth by rubbing your nail in around the barrel if it feels rough or pumps get some glass paper and rub it around the barrel but dont keep rubbing one side as you will make the barrel oval shaped do it all evenly until its smooth then put the piston rings in the little pin slots on the piston then get some 2 stroke and rub around the barrel also make sure nothing has dropped down inside the crank shaft if so this will jam it up then put the barrel back on

Not sure exactly what Bostitch framer model you have, but if it is powered by compressed air, as long as you remove the air hose from the nail gun, there should be no risk of the nail gun firing while you remove the jammed nail. There should be a way to access the driver area from the top of the nail gun, even via a latch or a couple screws. Remove the top part of the driver area and that should give you access to the jammed nail, which you can remove. Use long nose pliers or something similar if the nails are really stuck.

I think you camera must have either banged against something or fallen.
You are lucky that you are still able to take pictures.

The best solution is to take your camera to the Canon Service center in your area. If you good with small screws then you could probably open it and check the barrel if it is rubbing/scrapping against something and align the same. If not, then its best left to the experts. Personally I will avoid opening the same and goto the camera center..
Best of Luck...

If it has not been squeaking for an extended time you can get by with just changing the rear drum sleeve bearing (WE3X75). To do this, open dryer door, remove screws going up into top, allowing top to swing up and back. Remove screw holding front panel to side panel near top just under where the top was. Tilt front panel forward and lift off bottom pegs. Swing to side (you don't have to remove wires). Pull drum forward about 6 inches. (you don't even have to remove the belt.) Change sleeve at center back of drum. Make sure to inspect the front drum support slides WE1M481dark ones and WE1M333 white ones (about 1/2 inch x 2.5 inch strips at the top of the front panel which support the front of the drum), as about the time the rear bearing goes, these may be wearing also, especially the one on the left side.
