Idaholelewis, I Enjoyed your post!!
Question regarding the lyman 57SML site?
Did you have to modify anything to affix the site to the tang? I have a few TC rifles and would love to try that!
There is some Modification required, it is a simple task, i have done MANY of them. This is what you need to do to the 57SML Base, i do this with a Dremel Tool and a Course sanding Wheel, just takes a minute to do
And if your Tang is not drilled & tapped (some where, some weren’t) it will need to be, Drill & Tap to 8-32
It is an easy, straight forward process. First thing, is the Tang on your Rifle Drilled and Tapped for a Peep? TC Made some of Both, Some Tangs came Tapped for a Peep from the Factory, and Some Did not, out of my MANY Renegades and Hawkens only 1 of mine was Factory Drilled and Tapped, all of my others Required me to do it.
Not Drilled and Tapped for Peep. If your Tang is like this one you will need to Drill and Tap it to 8-32
Factory Drilled and Tapped for Peep, they added a Plug to protect the Threads.
The Lyman 57 Base will need to be Modified so that it Clears the Forward Wrist Wood of the Renegade.
It will look like this when you are done with it, i use a Dremel with a Sanding Wheel, takes about 2 minutes to do this. You can paint this black, or ignore it, it is Aluminum therefore will not Rust and this is Hidden as you will see below
Here you can See how it Clears the Forward Wrist Wood of this Renegade.
This is a FUZZY Picture of a Lyman 57 on 1 of my Hawkens, i did not have to do the Above sight base Mod on this Rifle, it Cleared after i added the Required Front Washers to take out the “Forward Tilt” here you can see the Corner that needs to be Removed from the Sight Base for Renegade installation. The Hawkens are a Bit thinner Through the Wrist of the Stock than the Renegades, Some Hawkens do not need the Sight Base Mod, But so far all Renegades i have worked with do, The Forward Wrist Wood of the Renegade’s are a Bit Thicker.
See the Corner on the underside of the 57 Sight Base i am Talking about here? Look between this pic and the 1 above
Drilling and tapping for Peep sight, How to find Dead Center of Tang
This is for education purposes only, You would be doing this with the Tang out of your Rifle of Course! This is just to Show you how to EASILY find Center of the Tang.
First, Measure the width of the Tang, all of the TC’s i have done Measure .500 across, Measure and make sure.
Now that we know the Tang is .500 Across, half of that is .250, Adjust calipers to .250 and Lock them down. With my Stainless calipers i can lightly Scribe a line here. Even if your Tang Measures Slightly Different than .500 just Take whatever the Full width measurement is and Cut that in Half
Now Flip the Calipers over and check from the other side, you will note the Lightly scribed line will match perfectly from this side :lewis: This is DEAD CENTER of your Tang.
All that’s left to do now is place the Lyman 57 on the Tang, use the Rear Tang Screw Through the 57 Base, This will Hold it FIRMLY in place, use a pencil and Mark the Front sight Base hole. Now Drill and Tap to 8-32, You can buy this Bit and Tap in a Kit, this is mine
And lastly, Taking the Tilt/Forward lean out of the Lyman 57
First, Push the Button, pull the Slider out and set it aside. The Lyman 57 has a Nice Flat Top surface, use this to your advantage
The Lyman 57 Has a Tendency to Lean Forward, Lay a flat edge on the Top of the Lyman 57’s Flat Base and you will find that it Leans/tilts forward, Like this
Here is How I correct Lean/Tilt (All of my Rifles are like this) I use Stainless Washers that are the Width of the Tang, and the 8-32 Screw will just fit through the Washer hole. On average, I ad 1 washer under the Rear of the Sight Base, and how ever many i need up Front to Correct the Forward Lean, This varies from Rifle to Rifle, You simply need to play around here and get the Base as Close as you possibly can, Being off a tiny bit one way or the other is Fine, all we are doing here is correcting the LARGEST of it.
Here is what i am Looking for, when i place a Straight edge on the top Flat surface of the Lyman 57 Base i want the Straight edge to Run as Close as possible to Straight in line with my Stock/Barrel, Like this
Might as well Strike while the Iron is Hot
How to install a Lyman 17 series Globe front Sight (Or Any Front Sight For that matter)
Things needed, Padded Vise, A Brass Drift Punch, and a 3 corner file with a “Safe Side” Both of these can be made at Home. A Modified Brass Bolt works fine, or better yet a piece of Round Stock brass about 3-4 inches long. The Brass Drift punch is so you Don’t damage the Barrel, Sight
It is VERY Likely your new 17 Globe Front sight will be to tight to fit your Dovetail, All of the Lyman 17 Globes i have done so far have been Tight, To tight, They needed Fitting to my Dovetail, Lyman makes them a little on the Large side so they can be fitted, 99.9% of Stock US Barrel Dovetails with be 3/8” (.375) The Lyman 17 Globes i have measured come in closer to .380
You can spend the BIG BUCKS and Buy an actual Gun Smithing Dovetail file like these, They have a “Safe Side” 1 of the 3 Flats is Smooth, this allows the file to slide back n forth in your Dovetail (Safe side down) and not cut, You are ONLY Cutting, enlarging the Dove Angle.
BROWNELLS 60° DOVETAIL STANDARD SLOT SIGHT BASE FILES | Brownells
Or you could get a Small 3 Corner file at your local Hardware like i chose to do, i ground 1 Cutting edge off Square on a Hard Bench mounted Belt Sander to make a “Safe Side” (mine is a Nicholson, AWESOME files :lewis
This is Somewhat of a Tedious process, GO SLOW and CHECK OFTEN!
If you only need a few Thou removed to fit, you can take it off the Bottom of the Sight Dove itself, I don’t recommend doing this if it’s Anymore than a few Thou, Any more than that and you need to Either Take material Away from the Front sight Dovetail (make it smaller) or Open the Barrel Dovetail (make it bigger) i have done both, i prefer slightly enlarging the Barrel Dovetail, I place the Barrel in a Padded Vise and Snug it up to do this.
On the other Hand, if your Front sight fits to loose in the Barrel Dovetail, If it is just loose enough that you don’t fully trust it from possibly moving, Use some Red Loctite! That will HOLD IT LIKE A ROCK, yet you can stil Drift it out. But if the Front sight is Quite loose, You will need to Build the Bottom of the Sight Dovetail up with Shim stock until you get it Tight.
NONE of this stuff is hard to do, grab the Bull by the Horns and do it! Quit Paying a Gunsmith to do these SIMPLE things!
