best flux
used with force 44 is great for soldering double barrels back together
Would you recommend this?
Yes, I would recommend to a friend
comet flux
This flux is perfect when used with High Force 44 solder. Very smooth flow at the right temperature.
Gets the job done
I use this flux with the 355 solder to install rings in bolt noses, bolt handles and sight installations.. never had any trouble with flow.. ive brazed carbon/carbon, stainless/stainless and carbon/stainless..I clean the work pieces with acetone..I put this flux on a small piece of steel wool and hold with hemostats.. preheat the workpiece, rub a little on the work area and go to work.. Ive used it for years trouble free..
Get a bottle!
I bought this originally to replace a front sight ramp. seems like a waste to buy 6 oz. for a few drops. Yeah, if that's ALL it can do! I've used this many times, on many different projects. Automotive to the vacuum pump I repaired today. Any time you need to join steel, where excessive heat might be a problem, this is my go to. This morning, I needed to remove a broken pipe nipple that was loc-tite -ed in. problem was there was a check ball with a non-metallic seat nearby that was also loc-tite -ed in. Solution, I tapped the inside of the nipple for a bolt, filled the check ball passage with water, Comet flux, 44 solder, spun the broken nipple out! The lower heat required to solder has allowed me to work near many things that could be damaged by too much heat. And not have to worry about loss of temper either.
It can work
I bought this product last year when I purchased some Hi-Force 44 ribbon silver solder. I only used them for the first time this week when I was mounting a front sight base on a Mossberg 590. At first I used my regular silver solder paste flux with the Hi-Force but nothing would adhere after repeated tries. It eventually dawned on me that the solder was beading and flowing out before the flux did, so I switched to Comet because it operates at a much lower temperature. This time the sight adhered.
Do NOT buy this product
All I can say is that this product does not provide the proper fluxing properties to let the silver alloy Brownells sells to flow. I have tried so many ways and times to make it work. I have finally given up. I have poured the contents in a gallon container in order to let it evaporate. Goodbye to a BAD product combination.
No. 4 comet flux
Too thin, evaporates too fast & does not work very good soldering under ribs
Not good for steel
One star only because that was the lowest rating possible. I bought this flux to use with the Brownells Hi-Force 44 solder to solder bushings in bolt faces for Sako extractor modifications on Remington 700 bolts. The flux was very thin (as expected since it is a liquid) and quickly evaporates and does not leave enough film to perform it's intended function. The solder would not wet out. I also tried other types of solders on test pieces with the same problem. I then tested several different fluxes and found one that performed very well, especially for tinning. Tinning is the process of coating both parts with solder prior to putting them together and is very helpful with steel. The flux that I recommend can be obtained from any good hardware store (did't see it at the big box stores) and is Oatey No. 95 Lead Free Tinning Flux. It is around $4. It has solder particles in it that will help tin your parts. When I was satisfied with the testing. I performed the bolt modifications and used the Brownells Hi-Force 44 solder with the Oatey No. 95 Lead Free Tinning Flux and tinned both parts prior to assembly. The parts were then fluxed again, positioned together, heated up, then assembled, a touch more solder added, then held in place to cool. Worked great. Not sure what to do with the Comet Flux now though... FYI - I am a gunsmith, welding engineer, and also have soldered several thousand copper pipe joints when doing construction work.
