Uberti Conversion Wedge
« on: December 14, 2019, 06:12:40 AM »
I just purchased a Uberti Open Top 1871-1872 revolver and am annoyed by the wedge design.  I have wondered why in heck Uberti used a design like this for this gun ( and possibly the other Colt conversion models) instead of the spring-less type used on original conversion and open top Colts.  Because of the change in shape of the forward edge of the wedge body, a spring type wedge meant for a percussion gun cannot be used instead.

The reason this displeases me is that once the screw is turned so the flat allows the wedge to be driven out, it comes out all the way. The original type could be released without turning the screw and the screw head would have prevented it from falling completely free from the barrel, just as the percussion spring type wedge is retained by the screw.

Has anyone altered the slot in the Uberti conversion wedge by milling (or using a Dremel) or is the wedge just too hard to work as it is?    I might consider buying a new wedge and modifying it, lengthening the slot.  Anyone need pictures?  I dont have an original conversion type spring-less wedge but could take an image of a picture in one of my books.

Hi Dan, I would like to see a photo of your wedge. The C&B Patterson uses a wedge that just has a milled center, no spring. Most all the other C&B Colts use a spring. A photo of your wedge will allows us to comment more intelligently.

Richard

I don't have any experience with that particular gun but I doubt the wedge is hardened to a point where you cant cut on it with a sharp file.

Thanks,  I'll  later post pics of my Open Top's wedge and also take an image of a pic in either Swayze's or McDowell's book showing the original O.T. and conversion wedge design.

If not too hard, I'll be milling the groove longer  as the Dremel would possibly give an ugly result...................if I decide to chance it and order a second wedge to do so on.

The shot from the forward edge of the wedge is supposed to show the rounded (radius-ed) edge that bears against the cylinder arbor slot. I suppose Uberti did this for manufacturing purposes that might ease fitting........it would definitely ease machining the arbor slot.  That does not bother me as the screw head clearance slot in the upper surface of the wedge.

Sorry that the image of the McDowell pic turned out so poorly.

I seriously doubt the wedge is hardened at all

Hi Dan, seeing your photo I now understand your issue. Most wedges are soft steel, the wedge gives instead of the barrel metal. IMO a dremel job won't do well. If I were you, I would find a small machine shop to mill the slot to your specification.

Is there a chance that wedge of a spring type wedge would fit? Wedge springs can be easily removed.

Regards,
Richard

Thanks,  I have  small machine shop in my back yard.   I am going to order a second wedge, fit it to the gun as a spare and mill out the slot .  At the same time, I'll get a non-flattened-head  wedge screw.
