Hi all,
the jolly old elf brought me a beautiful Uberti single action revolver last night but I can't get the base pin out to clean it. I sprayed some ballistol on the base pin from both sides and on the base pin nut and screw. It moves into the safety position easy enough and pulls back out of the safety position but no further. I'm considering unscrewing the nut and screw assembly but don't want to do that before asking CGN's advise. Also wondering if it's possible to adequately clean it without removing the cylinder?
Thanks in advance.
 
What do you mean by "it moves into the safety position"? All you should have to do is push the button under the barrel and pull the base pin out.
 
I wonder if excessive dry firing while the base pin was in the safety position has peened the end of it, preventing it from being pulled out of the cylinder?

This is possible... How far does the base pin protrude when fully to the rear?... With the hammer removed it may be possible to dress the peened end carefully with sandpaper or small jewellers file...
 
It's brand new so I don't think the base pin is peened. I have dry fired it but not with the pin in safety position. I'm taking it to the range tomorrow so I'll let it soak tonight and try again in the morning. I might try to hold the nut and screw with a small clamp, then lock vise grips on the pin and tap with a hammer.
 
Ok, 2 things, until this thread I never realized there was a safety position on the base pin, learn something new everyday I guess. The other thing, I just read through an Uberti manual that said on some models of their single action revolvers you may have to remove the spring loading pin to be able to remove the base pin.
 
I think what 09Outlander is talking about is the "first gen" styles, like the old west model. They have a thumb screw that contacts the barrel pin at an angle from underneath rather than the spring loaded cross pin.
As others have said, you should be able to push the cross pin in from the left side and pull the barrel pin out. When they are new they are a bit tight, but you shouldn't need tools.

I think your right. Also seems the black powder models are held in place by a set screw. There's no way it's coming out by hand though. On closer inspection this morning I found a metal burr hanging on the hammer side of the base pin hole. I just have to keep in mind that even though I'm a framer not every problem just requires a bigger hammer. I'm going to go shoot it in a half hour and then that pin is coming out. I'll post an update on how big a hammer I had to use.:d
 
Sixteen ounce rubber mallet. The pin had no chance really, I have a hammer collection that would make Thor drool. I locked it in my home made wooden vice and with guitar picks holding the retaining cross pin in place I attached a small pair of vice grips on the end of it and tapped with the mallet. It came out quite easily with the mechanical advantage. I then used 1200 grit wet-dry paper to polish the pin and the bushing it sits in and now it slides out no problem. Beautiful little gun too, very happy with it now.

I find that reading the instruction/operating manual for every new gun I get to be very useful.

I'm sure you do, and if you'd read the instruction/operating manual for this gun you'd already know that there's no mention of removing the spring loading pin to access the cylinder and that there's no part identified as the spring loading pin. But you didn't, so you don't. Thanks for your useful post though.

I never knew about it until last week when suddenly my gun stopped shooting. Took a while to figure out. The base pin comes back through the frame and blocks the hammer.
