Title: Hw barrels bent left or right?
Post by: Bayman on August 05, 2019, 12:56:24 AM
Today I purchased a like new beeman Rx1 (Hw90) and was checking it out for functionality when I noticed the factory rear sight has to be dialed way way to the left to correct the windage. Almost out of the adjustment window. I'm shooting indoors so there's no wind influence. Has any body else had a HW with the barrel kicked off to one side?

straightening a barrel isn't complicated do a search of the forum there are different methods. nothing to worry about. ;)

Is the barrel indeed kicked off to one side?  Or is the sight itself possibly not centered on the barrel.  Is the front sight centered properly?  Open the barrel and sight down the bore.  If it is bent in any direction it should be apparent.

No, I haven't :P.
Does the barrel look bent to the L or R?  If not, scope it and see what you get?
Check the bore, lead port and crown; I'd scrub the barrel too.
That's a gun begging to be scoped anyway as it should shoot accurately out to 80+ yards :D.
You likely got a good deal because the prior owner didn't know how to fix either ::).

I got a great deal and the guy only fired it a couple of times back in 2001 when he bought it. He bought this and a P1 pistol, both in 20 caliber and 2 tins of pellets ay the same time. I got both guns and both tins. One was factory taped closed and the other was nearly full. I don't think he messed with it at all. I'll scope it as you suggest and see what happens. On the original beeman quality check list it had "scope angle" checked off so I'm wondering if this rifle was "adjusted" for barrel droop at the factory. I'm really missing my machinist straight edge about now.

Both front and rear sight appear to be centered. I'd like to take the barrel assembly out to check it but I've never tinkered with a gas gun before. Just springers.

A long builders level will work in a pinch

No; all of my HW barrels have been straight.

Definitely bent in two places. Checked it with an aluminum carpenters level. I'll straighten it once I rebuild my shop. I'm in the middle of moving.

Otherwise I'm really liking the rifle. I think it being 0.20 caliber is cool. All my others are 177. Just have to learn how to play with the Elite trigger. It feels nice but a little heavy. Might be better to need a deliberate pull with this much power. Its making 21.9 fpe. The rifle is in great shape looks nearly new. Stock has a lot of character for beechwood. It was graded "select" on the original paperwork

The rear sights on my HW35E rifles are adjusted a bit to LEFT of center for me, a RIGHT off hand shooter, to hit dead center at target.
Same with the R9 and the HW80.  I mention this because it suggests a bent barrel to have the rear sights off set from center in windage, but it's actually the recoiling effect working to swing the muzzle away to the shoulder side holding the rifle.

None of my HW barrels, however, are bent at all.  I've looked down them all every time I shoot them and the break barrel rifles do bend a tad just from using them as a lever!  Try it and open the barrel and watch as you increase tension to cock it--you will see it bend down to the direction you are forcing it!

Thanks that makes a lot of sense. I've checked this rifle with both sides of an aluminum framing level and no matter which side of the level is used the barrel comes first slightly to left and than more noticeably hooks to the right. This rifles 18 years old and is in nearly new condition. It probably has less than a dozen pellets through it when I got it. Not a mark on the metal work. In the original paperwork it says that "Scope Angle" was checked. I suspect the barrel was tweaked badly at Beeman to correct barrel droop. These guns are notorious for that. As always thank you for your time and input.

Barrels are often "bent straight" at the factory like this.........

I bend the barrels of my HW springers so the poi is within 1" (or closer) from the point of aim using an optically centered scope. Here is the construction lumber and hardware "barrel tweaker" I use to bend my HW barrels, perhaps something similar would work to "undo bends"..........

I gotta get one of these!

Thanks NCED for taking the time to reply. I have multiple bends so I'm just going to use a v-blocks, a dial indicator, an arbor press and a straight edge to get it straight with the breech block. Then I'll optically center a scope and deal with any barrel droop or drift in my normal simple fashion. A secure bench vise and 3/4 " pvc pipe. What I really need is scope and mount recommendations for this monster.

Yeah Ned,
About a month ago I cooked up a project where I went through all my Weihrauch Springers and performed a 2 step process.
1) Centered the scope using my neighbors house about 30 yards away.
2) Re-scoped my gun to see where they shot (they all shot low ::)).  Then bent the barrels in my wood vise until they were within about an 1" on my 12 yard range (only 1 had a L/R issue).  After barrel bending, each scope only needed to be adjusted about a 1/2 turret turn on the scopes 8).

I got my scope idea from Scotchmo and the barrel bending from TimmyMac1 and ezman604 .........

I did this because I was sick and tired of shimming all my guns using 1/2" strips from a yogurt can.  The shims were denting some of my scopes and were just a bandage for the problem - barrel droop.
The name of the game is "keep it simple" with as few gadgets as possible :D
Right now you can see a slight upward slope on a few of my guns, however, they're dead on ;).

The only exception is my HW77K, I purchased a UTG drooper mount from PA.

I really don't know how important it is to have a perfectly straight barrel as long as the end is pointing the right direction  ;D ..........

Scope alignment issues aren't only "droop related" because there are also windage issues. There are adjustable mounts that will correct for both windage and evevation, however before I started simply bending my barrels I found that the setup time required messing with fiddly screws and muonting/unmounting the scope during setup to use the two adjustable mounts I tried (RWS C mount and a BSquare mount) simply wasn't worth the effort since they "shot loose" on my .177 R10 after a few months.

LOL....I more recently bought a RWS mount for the HW95 with "drooper feature" and found that my poi at only 18 yards was raised 5"! That mount might work well with a RWS that has visible barrel droop, however there is no way that I would bend my HW barrels enough to drop the poi 5" at 18 yards!..........

Anywhoo....I found it simpler to simply bend the barrel with my "barrel tweaker" than using adjustable mounts and the adjustment is permanent.

Here is one of my favorite pics showing that "barrel bending" really isn't an issue as long as the muzzle is pointed the right direction.........
