Re-solder Tikka 512 rifle barrel
#353985 - 03/06/21 02:58 PM

Hello!
I purchased a Tikka 512 double rifle in 9.3x74r. I picked it up today and found that the top barrel had pulled loose from its “saddle” and was no longer attached. I brought this to the seller’s attention but they are saying that some of those rifles had a free floating barrel. I sent photos of this muzzle compared to my 30/06 barrel set to show the difference. Does anyone know if this is repairable and how?

It looks like Midwest Gunworks can resolder shotgun barrels and ribs for $225 plus the re blue. Is there any other way?

I don't have my rifle barrels with me.

But I do NOT believe any were "free floating" at the muuzle.

I assume that "saddle" below should be attached to the upper barrel. And the saddles wedge below is what is moved sideways to influence the regulation. The rear wedges on the barrels influence height of bullet impact. So the muzzle ones affect lateral regulation. I never have had to fiddle with the front muzzle wedges.

I don't imagine resoldering the barrel at the muzzle is difficult or costly.

Someone more knowledgeable might chime in.

PS that rifle will NOT regulate and will not be accurate with two barrels groups.

Has the barrel sprung away from the saddle that much or are you exaggerating the gap for the purpose of the photo? If it is naturally sprung as much as shown in the photo then the solder is being asked a lot to keep the barrel muzzle attached to the saddle, there is quite a lot of force involved there. What is causing that amount of deflection if indeed it is natural? If the muzzle does sit down onto the saddle then a good epoxy for reattachment could work without affecting the bluing or other nearby soldered areas such as the front sight etc.

Just an "uneducated" idea from a non gunsmith.

But maybe have a look at the rear wedge. Is it pushed too far to create too much pressure to open up the barrels? The wedge is moved forwards or backwards to open up the barrel gap or decrease it at the back.

It MIGHT be pushing too hard at the rear of the barrels and is causing that large gap at the muzzle?

Loosening the screw holding the rear wedge, and reducing the pressure from the wedge, see it the barrel at the muzzle drops back down into the "saddle"?

I do think the barrel should not be "free floating" in the "saddle".

Have a look in the Valmet manuals provided on these forums and see if anything in those help you work it out. I will post a link once I look for the thread.

Silver soldering this should be done by compentent gunsmith. It looks like some bubba backyard expert has been tinkering with the barrel adjustments.

I have never seen a set of freefloting Valmet or Tikka double barrels. Ask seller to pay for the work as these barrels are not as they should.

jfkid- that rifle never had free floating. This is evident due to the witness marks on it's proper saddle and the base between the barrels.
The top barrel has become detached - either on purpose or perhaps by accident.
The sellers are lying to you, either through ignorance or on purpose.
Strong words, however strong words are necessary in this instance.

The seller is still unconvinced and insists “it’s supposed to be this way”. Any advice on how to change his mind?

I have not heard back from Midwest Gunworks since sending them a photo of the repair. Please any other gunsmith recommendations.

Seller is a moron or a crook or both.

Expect nothing from the seller and deal with it yourself via a highly qualified gunmaker.
I wouldn't trust the average "gunsmith" to do this properly.

If the barrels have separated by that much, I suspect something else has occurred, possibly a bent barrel.

I believe that Marocchi in Italy took over production of the 512S Finn-Classic series. Likewise I was once told that barrels sets for the Marocchi rifles could be fitted to the Tikka actions (Still required proper fitting). Might be worth seeing if they have an agent in your country who can advise. A new barrel set may be a better alternative than a repair to a potentially suspect barrel set.

The seller is a crook and sold you "damamged" goods knowingly. No way is it meant to be free floating. Look at all the images I supplied.

BUT unless the barrel is bent, I doubt it is a big repair. As said I would have a look at the big barrel wedge to see if it is putting too much pressure on the top barrel.

A good competent DR gunsmith will be able to advise you. And "re-fixing" at the muzzle as required.

Good names are mentioned on the forums. Do search on the double rifle forum for "Gunsmith". I will also start off new threads as a resource. People here can advise three US based names.

Give the seller a bad review if on a auction site.

Out of curiosity; did you ask the seller to take it back and refund your money?
Undoubtedly too late now.
IMO the seller is 1) woefully ignorant or 2) a scammer crook.

Telltale sign would be the corresponding patch of bare solder on the barrel where it was once attached to the “saddle”.

Hope you get some satisfaction jfkid - one way or the other!
You have a great calibre there, but yes, this job will not be for the faint of heart I feel!

Had a Valmet 412 years ago the the mid adjustment did the same thing- solder broke on the fixed portion. It was repaired cannot remember by whom but believe factory service stateside. Beware of silver solder- lots of heat involved to get it to flow properly. Should be able to accomplish a repair with lower heat solder or possibly an epoxy. May not be traditional but certainly some adequate high strength adhesives out there. MGW would be a good place to start.

JFKID:

not sure what kind of silver solder the manufacture manufacture used, but many really good gunsmiths I know are using a low temp silver, to attach sight bases and etc. that flows at 475 degrees f. and has 28,000 PSI tensile strength. Which means the repair can be made without effecting the bluing, but all the old solder will have to be removed first not knowing what it is. If the barrel is not bent any competent gunsmith should be able to make the repair. The solder is called "HI-FORCE 44" and is available from Brownell's

Their out there, you just have to search them out! But they are getting harder to locate. We have a great one in my area but all he wants to do is bolt action builds and is 8-10 months out, so he can be picky when he's turning business away.

It you still have the gun, any competent smith can handle that.
The saddle is only soldered to the upper barrel so you can put heat on it while the two are together.
If I remember correctly, the ring around the lower barrel is a snug fit but is free so that the barrel can shift with windage and elevation adjustments.
It certainly doesn't compare to a full relay. With the number of builders on this site, I am surprised that nobody else chimed in.
What I would do after it is corrected, is to send it out to get cryo'd and that would probably take care of any stress imparted by heating the barrel up when soldering.
I have seen cryogenic treatment work wonders on a number of guns.

Good luck and sorry about the late reply.

Cheers,

Tom

Have not seen this happen on the front adjustment, but the mid (vertical) adjustment does occasionally fail in the heavier calibers.

The barrels are designed to bend, to allow them to be adjusted to achieve regulation. Within limits of course.

The joint needs to be resoldered. The mfg used silver solder (braze), I have some of the exact solder here as well as the correct flux they used. I would not recommend low tensile solder, there is a lot of stress on that joint due to barrel vibration.

If you are in TX I can help you, otherwise any competent local smith should be able to handle it (not much different than silver soldering on a sight ramp).

You don't have to reblue but there will be heat damage to the adjacent blueing as this is not low temp solder.

The regulation will need to be redone.
