Ok, a new question just poped into the mind...if I wanted to put a new, better-looking bolt handle on a stainless M70 with the TIG, will there be any "fall out" from different metals mixing, etc....the final look is not important, as the whole rig will be in NP3 or somesuch "finish"...I am just concerned about the metal marriage...so, for those with the stainless????? I appreciate your putting up with the ramblings...Arthur Olds | ||

Arthur, it will NOT alloy, but it might matrix.. matrix means, in a solution (and it's in a solution while hot) is like marbles in milk... and then freeze that , you would see it's NOT choclate milk (blended) it's marbles frozen in milk.. not a homegeneous (no metal truely is) admixture, just chunks frozen together... long and short of it, if you like, are that IF it holds together while welding, it is NOT a weldament, it is a couple alloys melted and relying on each other's now frozen state to hold it together... in other words, it's non load bearing "weld".. i wouldn't do this for a bolt handle jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

All Remingtons have "welded" bolts. They are silver soldered. I have seen 2 break in the last year 1 ss and 1 blued. If your bolt is SS weld it with SSrod.TIG would be the best if blued weld it with mild steel and I can't imagine it breaking. We repaired all different sorts on machinery at work and as long as it was a good weld everything held | |||

I beg to defer about Remington bolts. Silver solder is adheisive, wile welding is coheisive. Big difference between the 2. Use the proper filler rod for stainless or the carbon bolt,along with heat sinks,and the right techinque and all will be fine. Hang on TITE !! | |||

If you notice I put welded in Quotes , yes I know it is not a weld but for the lay man It is "welded" 2 pc. bolts. | |||

If you use " I think a 309 SS filler rod " it will hold. Cant remember but there is a SS filler rod that just for that, SS to plain steel. Just remember to bevel the handle to get good penatration and set the welder to no more than 70 amps and stopping to let things cool abit from time to time.

You can get into lots of trouble welding dissimilar metals.IF they can be welded you first you have to know what metals are involved then pick the appropriate filler metal and procedures. | |||

At the risk of sounding too simplistic...why not just have your new bolt handle knob made from the same material as the bolt? Daryl Holland makes a replacement bolt handle for Remington 700’s that is a close match to the Winchester 70 bolt in profile. He sells them in stainless and it shouldn’t be that big of a problem to buy one and cut off the portion you want to use, have it checkered or whatever, and weld that to your stainless bolt handle. At least then you will joining two pieces made from the same material. If you don’t like Holland‘s bolt handle just have one made up out of stainless steel however you like it. | |||

I had my Ruger 77 MK 1 bolt knob turned down and threaded for a big Mil type knob ! Dwindling the worlds lead supply one cat at a time!! | |||
