stardust tommy Posted October 18, 2015 Share Posted October 18, 2015 what are the differences between the available hands for a K-frame? (non floating models) I have some -5 hands and they don't seem to work in a mod 13-2. they cam in more than the original hand ( they stick out a mm into the frame) can I weld up the front part of a -5 hand and fit it to the revo? or just remove some material from the tip of the hand? gr T Link to comment Share on other sites More sharing options...
stardust tommy Posted October 18, 2015 Author Share Posted October 18, 2015 (edited) picture... on the first sight I do not see a difference between the Kframe hands and a new L frame hand, is the difference good to see between L and L frame hands? could be the K frame hands are L frames...

stardust tommy Posted October 18, 2015 Author Share Posted October 18, 2015 left is L frame right is K-frame (if the info from the seller is correct), I don't see a difference Link to comment Share on other sites More sharing options...
Toolguy Posted October 18, 2015 Share Posted October 18, 2015 (edited) Using calipers, measure from the pivot pin to the top of the hand and get the top parallel with the caliper jaw. The measurements will vary a little, depending on technique. It should be something close to this - K .935, L .990, N 1.070. Don't worry about how far the hand sticks out of the frame, as that is self regulating because it can only go to the bottom of the ratchet base when the gun is in use. If you trim it back it may be too short to time properly. Edit to add - Thanks for the good pics. Edited October 18, 2015 by Toolguy Link to comment Share on other sites More sharing options...
stardust tommy Posted October 18, 2015 Author Share Posted October 18, 2015 If I meassure the distance it is close to .990... but I think I messure from the pin where the spring pushes against. If I measure a K frame hand this way it is close to .930 so I tkink I have a lot of L frame hands :-), if you put a K next to a L frame hand you can see the difference... in pic 2 there is no difference :-) If a good picture is the way to get good advise I can post a lot of good pictures! Big thanks for the good advise gr Tom Link to comment Share on other sites More sharing options...

stardust tommy Posted October 18, 2015 Author Share Posted October 18, 2015 used the hand from the first picture to restore an 686... perfect match :-) Link to comment Share on other sites More sharing options...
Alaskan454 Posted October 18, 2015 Share Posted October 18, 2015 I've had replacements poke out into the window and it will work just fine if the timing is ok. Just make sure to rotate the cylinder in the correct direction when closing it. Link to comment Share on other sites More sharing options...
stardust tommy Posted October 19, 2015 Author Share Posted October 19, 2015 I want my revolver to time perfectly with both right and left hand... in PPC we shoot both hands, a lot of used revolvers time perfect with right hand shooting but not when shooting left hand. seems like the hand gets bent 1 way by shooting almost always righthanded, a new hand solved my problem with this 686 the problem with a L frame hand in a K frame is that the cilinder wants to start turning before the cilinder lock is pulled down by the trigger... gr T Link to comment Share on other sites More sharing options...

It's almost impossible to bend a hand without applying heat with a torch. Link to comment Share on other sites More sharing options...
PatJones Posted October 19, 2015 Share Posted October 19, 2015 The pin can bend. This is what you're looking for when you check the "sing". Pull the trigger just enough to drop the cylinder stop and spin the cylinder. You should hear the hand ratcheting over the extractor. All this shows is that the hand can freely move in its slot. You adjust sing by bending the pivot pin. There is left and right sing, and they are often different. If you don't pull the trigger straight back sometimes the hand will bind in its slot. This can be different for left and right handed shooters as we abuse the triggers in different directions. Check the sing with the trigger pushed to either side, it's difficult to make it perfect.

stardust tommy Posted October 19, 2015 Author Share Posted October 19, 2015 this is the 686 I did, both right and left OK (hard to hear the second click with left) View My Video Link to comment Share on other sites More sharing options...
okshootist Posted October 19, 2015 Share Posted October 19, 2015 Power trigger shims can help make the right and left hand timing closer by reducing lateral movement in the trigger. Experiment with which side of the trigger you put the shim(s) on. Too many and the trigger won't return. Trying to get them identical is probably just going to lead to frustration.

PatJones Posted October 19, 2015 Share Posted October 19, 2015 I've never found a revolver where the sing is the same on both sides. I've also never had a gun that wouldn't run for a left-hander, but I understand that can happen if you don't check. Link to comment Share on other sites More sharing options...
stardust tommy Posted October 19, 2015 Author Share Posted October 19, 2015 I have checked about 70 revolvers by a gundealer (ex police revolvers) 7 timed perfectly (left and right), almost half of them only right and the other where totaly out of timing... bought al 7 good revolvers Link to comment Share on other sites More sharing options...
