sight tool

Does any one here make or know where to get a sight removal/install/adjustment tool that will fit a octagon barrel? Instead of beating them with a hammer and punch.
Thanks

Nope.   
A vice, a medium ballpeen hammer, a brass drift and a file with a safe side is all that's needed. If the dovetail slot in the barrel is the correct size leave it alone and file the sight dovetail.

I suppose you could force the sight into the dovetail with some kind of sight tool, but why would you? 

Just learn to do it the right way the first time.  Wink

I had a Marlin 1894 that someone forced a front sight into the dovetail once! The front of the barrel from dovetail to crown was broken off!
I always wondered how hard the previous owner hit it to break out the last 3/4" of barrel!

The reason I asked I got this henry big-boy and need to adjust the front sight and I gave it a pretty good whack using a brass punch and it did not budge and you can see a dimple where the punch was sitting.
Even tried moving the rear sight and same thing.

Your sights must be made of super soft steel.  How can you put a dimple in the metal using a brass drift?   

Use a wide brass drift, say 1/4  X  1/2 and file the end to fit the sight. Hold the barrel in the vice right under the sight. Support the the butt end with something. Try that. If it wont come out call the maker and ask what the*%$#@&*()_+ is going on with their @*&%$^#)(+_@%^ product. Maybe they glued them in.  Huh

It may be locked in with Loctite or something similar.  Heating it will soften it.

Some sights are equipped with a threaded tightening device of some kind.
(I didn't say 'setscrew' because that would be too obvious to miss.)

But, I'm betting you are dealing with Loctite or (worse) epoxy.  Some guys don't look down the road very far..

   Looking down the barrel from action end I always drift the sight to the left with brass punch for the first time on dovetails I have not cut. Some dove tails were milled with tapper. Hope this helps.  Ken


Ken, Doesn't that tighten them up in the dovetail going left? I always install them from right to left, but the farther left you tap them, the tighter they get in the dovetail.

Guy's, in order to eliminate damage to sights or sight bases I use Bullets to drift with. Usually a hard cast Postell but almost any good size bullet will do. They absorb all the damge and usually do nothing to the sight other than a little lead smear that is easily removed with Hoppes or some other mild solvent. We generally think of Rifle parts as being some kind of super tough hard steel. In most cases the opposit is true. I once had a guy come to me with  single shot with the Tang sight bent over about 30 degrees sideways. "Can we do anything to save this he asked?" DUH! I took a small plastic hammer and banged back upright. Went right back to where it belonged. Eyecup block moved up and down with no bind. A Brass drift punch gets harder on each end the more it is used, impact hammers the molecule structure tighter and tighter, thus harder. Try the Bullets, they do work and you can smack them as hard as you need. HTH, Regards, FITZ.

I use Derlin and make up my own punches for drifting sights and such. Just buy a 3 foot length of 1/2" Derlin rod and you'll enough to make a whole bunch. If you don't have a lathe you can just chuck up a 4 to 6 inch length in a drill press or hand drill and turn the end as needed. You can even file shape your punch ends into square, rectangle and custom shapes too. It is easy to rework or modify and cheap to replace when needed.

BTW, use your imagination with Derlin... I also use it to make muzzle and chamber guides, bench blocks etc...  

Hope his helps!

Regards,

Darryl

Oops... please excuse my mistakes spelling!  Embarrassed I meant Delrin

I get a lot of my stock and supplies at a local Fastenal dealer.

Hello Marlinguy
  It all depends who put the dovetail in. I try to establish if there is tapper first. If in doubt I tap to left first. Good Shooting.  Ken


The taper is usually built into all sights, not into the dovetail. If you remove any front or rear sight and turn it around, then trial fit it to the dovetail you'll see they are narrower on the left side of the sight, regardless of which side of the dovetail you attempt to install them.
Same thing for sight blanks. If you look at the underside of a Marbles blank, they have a dimple stamped into them to indicate the narrow side of the blank, which enters the dovetail first.-Vall
