jcc7x7 Posted February 26, 2019 Share Posted February 26, 2019 Does the 929 yoke work for any N frame Smith or vice versa? And where can I pick one up. Thanks Neil Quote Link to comment Share on other sites More sharing options...
Toolguy Posted February 26, 2019 Share Posted February 26, 2019 (edited) An 8 shot yoke (crane) or cylinder will only work on an 8 shot frame. The radius of the chamber holes is .030 larger so the crane has to be .030 taller as well. The 6 shot N frame crane (yoke) or cylinder will only work on 6 shot frames for the same reason.

Did the frame somehow get larger? Or is the cylinder somehow larger? I thought it was the same size and they just moved the holes further out.

Toolguy Posted February 26, 2019 Share Posted February 26, 2019 Good catch Swordfish. You thought right. Just did some checking. The cranes and cylinders both fit. However it would be a very bad idea to put an 8 shot cylinder in a 6 shot frame or a 6 shot cylinder in an 8 shot frame because the chambers will not line up with the barrel. One shot like that would probably blow up the gun and maybe the shooter. Quote Link to comment Share on other sites More sharing options...

The hands for a 627 and 929 are exactly the same The hands for an 6 shot N frame gun and an 8 shot N frame gun are the same LENGTH but the very tip of the 8 shot hands WIDTH is smaller to account for the shorter distance the cylinder needs to travel to the next chamber.

RePete Posted February 27, 2019 Share Posted February 27, 2019 I think that your only option is S&W or and authorised dealer. Quote Link to comment Share on other sites More sharing options...
Toolguy Posted February 27, 2019 Share Posted February 27, 2019 Try Jack First for S&W parts. Quote Link to comment Share on other sites More sharing options...
alecmc Posted February 27, 2019 Share Posted February 27, 2019 Smith will not sell you one. I've tried many many times. Your best bet is ebay or numrich. Quote Link to comment Share on other sites More sharing options...

pskys2 Posted February 27, 2019 Share Posted February 27, 2019 Try Brownells, Midway and https://www.gunpartscorp.com/ (used to be Numrich). Why do you need a Yoke? Quote Link to comment Share on other sites More sharing options...

Toolguy Posted February 28, 2019 Share Posted February 28, 2019 (edited) I'm thinking the threads must be offset from the bore. We're looking at a .030 mismatch in height. That's 1/10th of a bullet diameter. Edited February 28, 2019 by Toolguy Quote Link to comment Share on other sites More sharing options...

I was under the same impression. Unless the new style reissues of the 27s utilize the same frame and a modified cylinder allowing the correct offset? Be interested in learning more about this.
