Rebound slide riding surface smoothing

[MINI SSS]

What tool or home made tool do you guys use to fit in and polish the riding surface of the rebound slide? It's and awkward are to get to. Specifically my new 325NG. Does scandium frame require any special internal smoothing technique. I've done s.s. but that are is always tough.

I would check with Brownells they are always very helpful.

I use a Norton Arkansas polishing stone, square, 1/4 x3 ultra fine. $13.79 at Midway.

I to, use a hard ,flat, Arkansas stone. Smooth both sides, and knock off any edge burrs, with Emory cloth.

I also smooth the sides of the side plate, and frame, in which the slide moves.

Running over the surfaces with your finger, should show rough spots.

This area is IMPORTANT in getting a nice trigger pull.

Like JohnK said, just knock off the high spots.
No need to make the area look like its chrome plated.

Some 600 grit wet/dry paper wrapped on a rubber eraser will knock off any burrs, don't go overboard with polishing, just smooth.

New 696

Today just as this thread was posted I was bonding with my new 696 purchased from a forum memeber. Doing this exact procedure to the rebound block. Happy to report the action is now butter smoooth. 100% stock springs and the trigger pull is stellar. Looks to be a great gun. Regards MIke

Mike, What do you consider stellar? I've polished my RS block and installed an 11 lb RS spring and still can't get a pull below 34 ounces!
I used to have a 24 ounce trigger on this 629-4 Mtn Gun and then I hadda send it back to Smith due to "push off" from use. When I got it back it had a 60 ounce trigger pull. I've been slowly working on it over several months now, but can't seem to get it where it once was and where I like it. Any suggestions out there?

Were you asking in part about something like this?

As far as smoothing out trigger pull, you've got to look at every moving part and contact surface. Use a fine stone and go SLOWLY. Kuhnhausen's book is priceless. Any hammer rub? Trigger? Might need shims. TW25B grease is great on the ebound slide, the rebound spring, and a tiny bit on the hammer/trigger contact point. I've even smoothed out the inside of the rebound spring tunnel.

Now that's an item I've not tried yet!

By the way, where do you get the grease you mentioned?(TW25B)

Here's the 3/16" Cratex rod I used to smooth out the inside of the tunnel. Please DON'T attach this to a power tool. You just want to take off any rough spots on the surface.

This is great stuff, guys! Thanks for the info. I've been kinda prowling around on here hoping to find some info on trigger work. I have a 686+ in the mail that's going to get some lovin' when it gets home.

They probably put factory springs back in it. Get a spring kit from Wolff. The main (hammer)spring will only help by 1/2 lb. The rebound springs make more of difference.

As to smoothing out the rebound slide I use, 320, 400 and 600 wet dry on a flat (kitchen counter top)

I just use a small flat edge screw driver to push in and remove the spring. No special tool is needed unless you do it all the time,

The TW25B lube is sold also by Midway under NRA approved lube.

The OP's question was how to smooth the area in the frame that the rebound slide rides in. Can anyone answer?

Good point We should learn to read

A small hard square piece of wood or metal with a piece of wet dry paper. I imagine there is a small stone available somewhere

 

[Monad71]

I use a 1/2" x 1/2" x 3" Norton ultra-fine Hard Arkansas stone. These stones are designed for polishing. Be sure to use some good quality oil on the stone. You should be able to find them on eBay or do a google search. Good luck!

 

[haggis]

After you're through with everything else, use a fine stone to break the edges of every transverse straight edge on the rebound slide. It makes a big difference when you're trying to squeeze out that last little bit of smooth. Also, don't forget that "smooth" does not mean "polished". If it feels smooth to your finger, that's enough. Truly polished flat mating surfaces can generate a high level of adhesive drag.
