OT: why are sights so tight
Why do rifle mfg'rs put sights in so tight? Henry,winchester (japanese) and rossi.
Yet they all tell you to adjust them "tap" them left or right well a tap on these ain't gonna do it.
On my japchester I cannot move the front sight, started with a brass punch and a brass hammer, did not budge, moved to a steel ball peen hammer, no go, moved to a 2 pound hammer and still no luck. The rifle is locked down in a padded vise.
Don't want to mess up the finish on either the sight or barrel, bought a piece of acetal/derlin gonna try that with a 5 pound hammer.
By the way that stuff is really tough.

Re: OT: why are sights so tight
You might need to be using a very small diameter punch so you're only trying to move the right part.

Re: OT: why are sights so tight
Maybe you could use ice or dry ice to the sight for a while, then heat the barrel a bit so the dovetail opening is bigger relative to the sight. I've used that method for stubborn screws (along with Liquid Wrench and Plentiful Cursing).

Re: OT: why are sights so tight
Yeah, IMO, the cursing is what really does the trick.
Government office attracts the power-mad, yet it's people who just want to be left alone to live life on their own terms who are considered dangerous.
History teaches that it's a small window in which people can fight back before it is too dangerous to fight back.

OK, just to be sure, you ARE trying to push it out from left to right as seen from the rear of the rifle?

Bingo!!! we have a winner!!!
The old sights should be driven out from left and the new installed from the right side. I've had people tell me that dovetails are cut into the barrel on a taper. That's just not how they do them. Standard dovetails or at least the most common are 3/8 (.375) X 60 degree straight across cut. The taper that these folks are seeing is the results of driving the sights in and as they go in they swedge the dovetail in the barrel out on the right side and the bases of the sights down on the left side creating this taper. That's why it's important to always install from the right and remove from the left.
On a side note, I've seen Rossi's that had tight spots in the bore because Rossi forced the poorly fitted sights in.

Re: OT: why are sights so tight
Good point on that; it DOES make a difference that all the swearing and Liquid Wrench and so on won't overcome without making a MESS of the sight.jnyork wrote:OK, just to be sure, you ARE trying to push it out from left to right as seen from the rear of the rifle?
I used to feel dyslexic because of forgetting which way the 'rule' was, but finally remembered it because many if not most guns (bolt-actions, single-action revolvers, lever-actions) load and/or unload from the right side, so if cartridges go in from the right and out to the right, makes sense parts would, too...

The front sights on the Miroku Extra Lightweight rifles are impossible to remove with a drift pin. I simply cut them with a hacksaw and knocked out the pieces before installing a NOS Lyman No 4 sight.

Re: OT: why are sights so tight
My Rossi was shooting to the left so I finally did succeed in moving it to the left. Giving up on the little brass hammer and drift punch, I used the tool that was to unlock the hubs on my Cadillac as a drift, padded the barrel, used a real hammer and HIT IT!

Re: OT: why are sights so tight
I don't have much luck with the small punches but did fine with using a larger diameter bolt as a punch.

Re: OT: why are sights so tight
Not simply to be contrary, but the front sight on my recently new '92 Rossi was actually about "right."
I did not notice any discernable difference between it and any other I have ever moved/removed.
Small brass drift, 8 0z. ball peen and a few well-connected raps drove it out with the barrel supported on a wooden block and clamped down to the bench with a quick-clamp.
In fact, after I had it out for the third time, I gave the rear lip of the dovetail a gently tap to ensure I wasn't loosening it up.
