How do I take this apart?

[Dr. D]

The pictures below show a door stop from the forward cabin. I took the doors out since they kept getting in the way. I accidentally "touched" this door stop with my foot and it fell out. Well, of course, as the screw going into the bulkhead was only 1/4" long. If I replace the screw with a longer one it should be OK. (This is in case I sell the boat and the next owner wants to use the doors.)

Now the problem: The screw won't come out of the copper colored disc and I can't get the disc out of the stop. Anyone know how to do this?

pop the cap off

If you mean the copper with the hole in it, there doesn't appear to be a way to pop it off. Pulling on the screw doesn't work, either. The top of it doesn't appear to come apart.

Put the top in a vice. Grab the screw threads with a vice grip pliers and push towards the edges.

A sledge hammer would do it. How about filling the hole in the bulkhead with epoxy and then setting the screw in it and let it set, basically gluing the fixture to the bulkhead? I'm afraid applying brute force to remove that disk and screw has a good chance of damaging the fixture or scratching the finish.

Looks like it has a magnetic pivot at the small end? I would see if the larger chrome piece might unscrew from the inner brass piece. Some vise grips pulling on the screw might give enough purchase to hold the inner while you turn the outer. A bit of penetrating oil between the brass and chrome portions might help a bit as well.

Likely a variation of something like this.

Good idea. Doesn’t work.

In that case, I respectfully bow out.

Good Luck

Is it possible that you could find a new one and see if the part came with instructions?

A variation of Benny's idea. If the screw is stationary and doesn't rotate, fill the hole in the wood surface with epoxy. Allow the epoxy to completely harden. Redrill the epoxy with a slightly smaller diameter drill as compared to the screw, and rethread the screw into the drilled epoxy.

Sometimes, destruction is warranted, if only to find out how they put the damned thing together.

Winner, winner, chicken dinner!

I stuck the head of a Phillips head screwdriver into the hole in the brass piece until I got purchase on the brass piece. Unscrewed easy. Thanks!

Wonderful.
No Vice/Vice Grip damage to the finish.

Wrap it in plumbers cloth abrasive with the cloth towards the the finish. Protects the finish and allows you to get bite.

Dr. D,

If you just need the hole for the screw to be a little tighter I suggest sticking a toothpick in and breaking it off flush, and then reinstalling the screw. Sometimes it takes two toothpicks.
