Another tennon pinning question, please, pics

[Mule333]

Hi, jus read Gangreen’s thread. Some great advice on soldering.

I’m about to solder my middle tennon on this swamped barrel. I like to think 2-3 steps ahead on problems that may arise.
Question is, should I cut the “ears” off the tennon with a dremel, or will the solder joint hold if file down either side?

Thanks, Mule

A good soldering job would hold fine. You wont be able to get a good job with your electric solder gun though. You need to get the barrel warmed up enough for solder to flow, and that simply wont have the heat thatd require.

I’d cut the base of the tennon to the width of the barrel flat first. A torch will be required for heat. Use the least solder possible for the strongest joint.

How about this.

That looks much better

Quick question….. why are you soldering the middle one? Should be plenty of meat there. The one in the waist would be of more concern.

38” swamped barrel. 40cal. Installing 3 tennons. I assumed 3 would be enough.

The middle section of the barrel, I’ve been told is a little thin. Being the novice that I am… I assumed soldering was the safe way to go…. For the middle, that is….Not sure what you mean “The one in the waist”. But I’m willing to learn all I can. If you have a different approach.

Thanks, Mule

Soldering is the safest way to go IMO too. Solder all three, don't change horses, and fasten the other two differently! Waist is the thinnest.
Make sure both barrel and tennons are clean and fluxed prior to heat. Size the tennon with the flat, as others have said. You can do it later after soldering, but you then have to be careful not to put undo scratches on the barrel where it will invariably happen.

The Mapp torch will work but be careful as they will heat things up quick. I did mine with just the blue bottle propane torch. Heat just enough until the solder flows and the Flux sizzles. If the barrel and or the tennon turns red, you're much too hot.
