I was just wondering if heat is still used to join CL barrels and if so how much of it and where?

No that's the beauty about CL barrels. The makers can use an epoxy to join them so the heat can't damage the barrels.

They are fluxed, wired together and silver soldered or brazed in an electric heating coil for precise temperature control! The heat doesn't damage the barrels!

Well of course...the barrels are joined together at the breach using hard solder/braze flowing at 900+ as is the forend loop(sometimes). Ribs are still at 450 degrees.

Everything is the same.

The real benefit of CL barrels is the ability to get things smaller than a monoblock will allow at the breach if the maker wants to push it. Because of this the action can also be shaped down more. Of course you also dont have any seams. Are there performance gains? Only in handling if the benefits if CL are utilized. Shoe lumping can achieve the same thing.

Here is a picture of a Heym barrel set which is a shoelump barrels set before it is carded so you can see the brass but the joining is the same for Chopper lump barrels.



As Aaron says there is no epoxy used. The only double rifle I know of that used glue for joining barrels was the now defunct Rogue River doubles that used the glue used to hold the heat tiles on the space shuttle. That didn't turn out well because it negated the trial and error method of regulating the barrels. That system was dropped and they started making the California Rigbeys which are now defunct as well.

You two sure don't know how to have any fun. We could have strung this along for weeks.

Yes, that too!!

Dang! They could have a least let this sit for a couple of days.

Jerome told me that Verney Carron uses silver for their chopper lumps ! And I guess that has to be done with heating !

I know of one company that uses Gorilla Glue (commercial grade, of course)...again, no heat.

Nice Mike!! This is probably the best option yet. Adjustable regulation in the field would be really nice feature!

Isn't that the Sabatti system of joining barrels?

Todd, you have been away too long. Here is the Sabatti system:

Don't laugh; I started out actually using hose clamps for regulation. (true)
I now use Elmers, the yellow stuff, to hold barrels together, exclusively for chopper lumps;; it does not need heat.

No doubt about it, that yellow Elmer's is the bomb.

DO NOT use white Elmer's; that crap is made for first graders art projects.
Use only the yellow stuff in the plastic bottle.

I believe the yellow glue was named after Elmer Keith? Made from Bald Eagle beaks IIRC.

Elmers is overkill....

No, I like the liquid: I want it liberally running out of the joint so as to make sure I have complete coverage over everything in sight.

Some of your "best quality" bespoke guns do use heat, since the barrels are forged together. A dying art.

On my WR they used DoubleBubble. JJ had to reregulate last year and he applied Red Loctite. So far so good.

You guys are GREAT.

Get the idea Shootaway?

You see, thats the difference between a Bermingham maker and a real gun maker. A London maker wouldn't go for that pre-made store bought crap.

Gun makers or gum makers? I am surprised no one has mentioned duct tape. I was talking to a leading London double rifle maker who said if a double rifle cannot be regulated with duct tape, it just cannot be done.

And if the duct tape fails to produce the desired results, one can always fall back on this:

If memory serves me right, Geoff Miller used to do this very thing....

A question about the finest London makers only about the glue, duct tape, Dremel tool, etc., shown above.

Are they bought from vendors or are they made in house?

I think you should try GORILLA glue it doesn't run as much.

Funny man. Everyone knows that the English guns are just assembled in London out of parts bought in China on Alibaba. And you claim to have written a book on doubles.

This does not bother me one bit because I have been lifted on a cloud and the hunting gods are calling.

Mushrooms have that effect.

You sure those voices in your head are the hunting gods? And is it true that Cal is the wind beneath your wings?
