Flux for Silver Soldering bolt handle

[PJ/AIR/FIRE]

Just curious as to what is the best flux to use with Brownells high temp silver solder for bolt handles. Any input would be appreciated.

ultra flux

I like Stay-Silv, made by Harris.

Are you using soldering alloy, or brazing alloy? You need to use the right flux.

Cadmium free or cadmium type silver brazing will require different flux types as one wets(cad free) & one flows(cad type).

There is a less expensive,less frustrating option-

This is for silver braze, I would not silver solder a bolt handle on.

Depending on handle selection,99% can not be TIMED correctly w/o adding material...in the right place(s)

This is what I use for the cadium free. I have no problems getting them timed right with any handle with some simple modifications. I dont add material. Different ways to skin a cat. I'm going to make a video of the next Remington I do to help all the guys do it themselves.

This will be silver braze. For a PTG bolt handle.

Do you have experience with silver brazing?

 

[PJ/AIR/FIRE]

Another question. What is the recommended brazing material you guys are using?

 

[PJ/AIR/FIRE]

Limited brazing experience but very proficient in all welding processes. Yes practice brazing before you do the real thing which is the plan. Thanks for all the replies already.

Does any one like the ribbon solder sold buy brownells

Once again Alex,you can BS some of the people some of the time but not all of the people all of the time!
Add a couple bastardized screws to your attempt...they may save you hours & hours of re-work.

Cadmium type silver braze.
You'll have approximately 75 degrees of temp variance of both pieces to braze.
Too cold & braze will not flow.
Too hot & flux burns-stop,let cool,remove flux by manual means,start over.
1400deg F will be red hot, rendering bolt body & handle....basically junk on your first attempt.

Something to remember [important]. Tig welding allows control of the heat on the bolt and handle. Using a torch to silver braze does not!

ribbon braze strips work best by induction method.
wire is visually drawn into/through the joint by torch method.

Parking a Cat D10 dozer(95Ton) to heat sink your bolt/handle will move once heat is applied!

Could you get away with parking a d-11 on it thought

Try it,you may get lucky!

I'm not the one trying to make simple bolt timing into rocket science to scare people from doing it themselves and just sending it to you. I'll try and get the video done asap so hopefully more people and smiths will just do it themselves.

 

[JRS]

Simple bolt timing, and negatively affecting the bolt and handle are quite different.

The best I have seen were Lazer welded. The second best are TIG welded, fusion welded with argon purge. The third method is silver soldering. I have used the silver wire/ribbon induction method and the silver dust in flux paste. It is sold by Brownell and it is not cheep. Think a small gar was $70 plus dollars. For the best bang for your buck have then either Laser or TIG welded. Dan does a great job, understands bolt timing and welding. I know because he has done bolts for me and provided me with hours of instruction on this subject.
