I'm trying to take off my needle plate cover so I can bring the feed dogs up manually (I posted about this months ago but I've been dealing with some personal issues so haven't been ready to try to do it until now), but both the screws were stuck. I was able to get one of them by hitting the top of the screwdriver with a hammer, which was a suggestion I found on WikiHow, but the other one is right where the front of the machine is so I can't do that. I did try WD-40 but that didn't work. I think part of the problem is because the front of the machine is right there I can't hold the screwdriver upright, I have to hold it at an angle. The machine came with a small screwdriver, but even that one isn't small enough to fully fit under the front of the machine for this one screw. Googling for "needle plate cover screw stuck" gives me results for people talking about getting screwdrivers with short handles and using PB Blaster and Tri-Flo (I don't even know what either of those are). So is it true that even if the screw weren't stuck it would be impossible to unscrew it unless I can hold the screwdriver fully upright over it? If that's true I don't understand why the screwdriver the machine came with doesn't have a handle short enough to let me do that!
