Barrel bending

[AirShot]

Back in a 80’/90’s Weihrauch (maybe Beeman) was marking the gun gun box “scope angle or barrel angle” forgot which. These particular rifles were inspected and found to have the least amount of barrel drop. They were recommended for scope usage. It seems to me that if Weihrauch could have simply manipulated the barrels by bending them in line, they surely went through a lot of trouble inspecting and labeling the box while making their products look inferior.

Or, that Dr Beeman being the "salesman" he was, simply found a way to get a few more bucks out of the customer. 

Cause let's face it, how do you know you actually got a select barrel angle? What if the gun beside it had an even more select barrel angle and got tossed in a box that wasn't marked or upcharged? Or more likely, what if they just all got marked "scope angle" and an extra $3 was added to the price? 

Or what if Beeman took the gun out of the box and stuck the muzzle in a hole in the wall and gave it a swift bend, lol. 

The only thing we are sure of is that Beeman was a helluva "salesman" to put it lightly....

AMEN.....Beeman never made anything, they contracted others to make it for them !!

Thumper,



Could you please explain to me the process of going about it in the bottom paragraphs please? Greatly appreciate it.



If you have a trailer hitch with a 2" receiver, which I assume is what you're using, a vise mounted on a spare receiver is a HANDY thing to have and will solve your problems! I have one stashed around here somewhere.

Last hairbrained idea if you don't have a vise, is to bolt a couple blocks of wood to the leg or anywhere on the table or something sturdy that would fit against the sides of the breech block. One on top and bottom, and just pull up. Easy and cheap and removable when you're done.

Both are with the barrel removed.

Lots of service trucks (phone company, lineman, etc.) have a table vise welded to a receiver that slides into a receiver hitch like a hitch ball would. If you buy a vise but don't have a sturdy table or the space, having the vise mounted on a receiver hitch is handy to have. Use it at home or anywhere you drive your truck. I used to have one I carried in my truck when going on off road rides. 

The wood thing is just taking a couple blocks of 2X4 and bolting them to the something sturdy, spaced apart so the the breech block fits between them snugly. Then sticking the breech block between them and then pulling the barrel to bend it as needed. No vise needed with this method. 

Maybe that helps?

I put the barrel bending to the test. 

FWB 124. The scope was centered. You can see where I slowly tweaked the barrel ( used a fork in a tree ) and walked the POI up. When the shots were near the bottom of the dot aiming point I fired multiple shots, a slight tweak then multiple shots again. Target to the left is where I used the scope adjustment and the top target is the last shot. IIRC, I ended up with 12 clicks up and 4 clicks to the right. Before the barrel adjustment, it was 3.5 revolutions of up adjustment. The range was around 15yds.

I extended the range to 25yds and went down the line of some 12ga shells laying down with the base facing me, a few shots at 42yds on a spinner then with 2 shots, sent a 12ga shell flying also at 42 yds. POI and POA are the same as before the barrel bending, so it didn't cause any weird phenomenon.

Helped? It sure did. I really like the idea of the hitch.

Does the hitch version needs welding or is there a way to bolt it

Leo, I tried that way once and it was not no where as easy as the trailer hitch. More controlled? Definitely. I am glad you posted it though for those who are nervous or skeptical in doing so.

So... years ago I had an unfortunate accident with my R1 and the barrel was bent somewhat badly. I tried straightening it with no success so I built this. It was very controllable but took a lot of effort to straighten. I had it pushed into a bowl shaped curve before it finally straightened. I used a long straightedge to judge it's condition. 

A year or 2 later I picked up an RWS 35 that had the trigger pulled while the barrel was open. Wasn't bent as bad as the R1 but when I went to straighten it , it bent like butter. Was SO much softer than the R1 barrel. I've straightened a couple more and bent some for less droop, also.

Just my experiences,

Bob

Dude, i think that is a nice invention. Good going
