Revolver Frame Lug Question

The frame lug on my 1980 vintage Model 64-3 revolver has loosened and it turns a bit counter-clockwise. When this happens, the cylinder binds on it when opening and closing. When I turn the lug back to it's correct position the cylinder doesn't bind.

I've ordered a replacement frame lug, but would like to know if this is a repair I can make myself or would I be better off having a gunsmith do it for me.

Any advice?
 
Lug question

you should be able to do it. Just locate the pin inside the fram and with a smallhammer & punch tap the old one out.
press the new one in and that should do it. if i the new one is loose put avery tiny tiny drop of loctite on the shaft of the lug.
 
Disassembly Question

I have an additional question, guys. From a couple videos I've seen it appears that most or all of the inner parts may need to be removed to access the back side of the frame lug. Is that correct? If not, what parts must be removed to replace the lug?

Thanks.

The lug is long because they are staked in place. So lay the frame on a solid block of metal (lead) and stake it from inside. I use locktite also so it won't ever twist when I fix them. File the insides smooth then reassemble the action parts.
 
The proper installation method for the S&W frame lug is to install the lug with a little Loctite Red if you want.
You can just re-rivet the original lug, and this will possibly safe some fitting effort.

Put the side plate lug down on a bench block with a sheet of paper or brass sheet under it to protect the finish.

Use a large 3/8 center punch with the tip rounded off and a small hammer to rivet the tube on the new lug.
The idea is to round the tip off enough that the punch will flair the tube, not put a punch mark in the tube.
Make SURE the rivet is flush enough to be under the level of the side plate and won't catch or drag on the action parts.

If you've used a new lug, you may have to shape it to allow proper clearance with the cylinder as it's opened and closed.
Compare the new lug with the old lug to see the beveling needed.

Properly riveted, the lug will never come loose again.
