Stripped screw help

[stevie]

Hi All

So picked up a used Uberti 1861 that was used. Turned out the person kept good care of the exterior but neglected other parts. Anyway when i took it apart this screw was pretty much stripped. I made it a little worse. Any idea how to remove it?

The other screws came out easy, this one stuck. Guess thats why it was stripped in first place. The nipples were rusted in place, trying to remove them now.

A few of different methods, one you can take a slotted screw driver (hollow ground), place it in the slot and try to tap the screw driver in further to the slot with a hammer. Not sure that will work in this situation though. Secondly try a rubber band laid lengthwise along the stripped slot, push your screwdriver in as hard as you can and see it that will back the screw out. Thirdly would be to take a rotary tool (Dremel, etc) with a cutting head and see if you can make the slot a little deeper then use a narrower screw driver head to remove the screw.
The most time consuming would be to drill down the center of the screw and use a screw extractor to remove the screw without damaging the threads.

You may be able to get a little grinding bit in a dremel tool to make the slot a little deeper and then get it out. I've done that before on stripped screws. I messed up one of the screws on my 1851 the other day, ordered a new one from EMF for $5,they carry all of them.

Thanks for the info. I tried the rubber band method did not work. Will try to hammer down a screw bit. I have a set of Brownells screw drivers.

I have a dremel with consider that next. Thanks

Just be careful with the dremel, don't mar the frame if you can avoid it.

If you cut the slot do it at 90 degrees to the original to get a cleaner slot.

I got it out. Hammer on the bit, then used the rubberband. Came out easy, thanks for the help. Now to order another screw.

Thanks All!!!

Is the screw stripped or are the threads in the hole stripped? Or both? If the threads in the hole are stripped, they should be retapped to get good threads. Be sure both are good before reassembly.

You got it out. Good job. It appears that it is the slot in the screw that is stripped. You need a properly fitted hollow ground tipped screwdriver for working on these often soft screws in these Italian replica revolvers.

You are going to need a good penetrating oil such as Kroil, Aerokroil, P'Blaster, Liquid Wrench among others to soak that screw. You will need to wait several days up to a week or two for the oils to penetrate. Reapply the penetrating oil often. This soaking will be required for both that bolt spring screw and the nipples. Put them in your freezer for a day after the soaking.

Get a good nipple wrench sized for your revolver nipples such as this one from Track of the Wolf.

You will need to get a dowel rod that slips into the mouth of the cylinder. You need two lengths about 5" long and a sturdy vise. Put the dowel rods into opposing cylinders and clamp the dowel rods in the vise. Put your nipple wrench on the nipple and using a small hammer tap and turn. The nipples should come loose. You may need some heat on the nipples. Good luck.

Thanks for the advise on the dowel rods. I was able to remove 3 of the nipples, 3 to go. I pretty much ruined my nipple wrench. I ordered the ted cash wrench. Cylinder currently sitting in a pool of Kroil.

Get a 1/4" drive socket. I think some guys use a 5mm or 6mm socket. Grind a slot as wide as the sides of the nipple and use it to remove those stubborn nipples. I had to mount mine in a drill press and used downward presser on the press and turned the chuck by hand to get out some badly stuck nipples on a used revolver i bought.

 

[stevie]

Thanks, I'll try that later. Letting Kroil do its thing.

5 mm or 5/16" will work to reach into the revolver nipple seats. I made one from a hex drive socket and used a hex drive impact driver. Mustn't have been all that well received as the small impact drivers are hard to find.

Got a dowel and 5mm socket. Was able to remove another nipple, 2 more to go. Going to let the others soak for a couple more days, it looks like the raised area of nipple that rides on the wrench is starting to strip. Will probably wait until the Cash wrench arrives on Tuesday to give another try.

Just in case i cannot remove the nipples... Will todays Uberti 1851 cylinder work in a 2010 1861? Gotta keep my options open.

right, because if you go too deep into the existing screw head slot, it may break off one side of the screw head.

Kroil is a good tool, so is a “blue wrench”.
Those nipple wrenches are pretty soft, I ended up making my own by dremmeling then filing out the center of 1/4” drive sockets, 5mm or 6mm I think.

Putting them in the freezer is an interesting idea. What does it do?

Option 2, use an Easyout.

When you put the metal cylinder or other parts in the freezer, the metal contracts. Sometimes that changes the contact with the corrosion and the penetrating oil can work. When the parts are brought back to room temperature, they expand also breaking the contact with the other parts.
