Re: Welding Scope mount to the reciever
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Clark</div><div class="ubbcode-body">I have welded a couple ring pairs to the receiver.
Before the FBI put Federal Arms Corp out of biz, they imported from China a 91/30 type sniper mount for AK47s that required drilling and tapping.
But if once cut off the bottom half, they had 1" steel rings on a half arch.
I made a fixture but turning a rod on the lathe until it fit the bolt bore.
I turned a rod until it was 1" to fit in the rings.
I made two plates with V grooves in them.
I clamped the two rods between the plates.
The receiver and rings were then fixtured in position.
I welded the bottom of the half arch to the left side of the receivers.

Scope mounts are often soldered to the receiver in $10k Mausers. This is the double bridge.

Hi dont even think that soldering and welding are the same, soldering is done at a low heat and does not change the properties of the steel but with welding you will change the structure of the steel. i have welded a lot of steel in my life and their are ways that things can be reduced in the way you change the properties like manganese type steels when welded with low hydrogen or other carbon steel electrodes if you tap the item welded onto them it just shatters off but if your urse stainless it is solid and the only way to attach lifting lugs to them safley to be remover later. aslo tig welding with the correct setup reduces excessive overheating of the item but in high carbon steels like actions the best thing is dont do it.
Now on an action like an AK the steel is crap and welding would not likley make the action weeker but it could by inducing stress points into one and one day the thing could just let go. if you had an action that does not actualy have any pressure like one with the lugs inside the barrel that the bolt locked into like an ar or rem pump rifle welding the reciever would not make it unsafe but any reciever that has to be an integral part in the locking of the lugs and holding the barrel in at over 60000psi is asking for trouble. their are rifles out there with lightweight alloy recievers but they dont take any pressure they just hold the bolt in lace and the trigger so the rifle can function.
The best thing is Never weld any rifle action or reciever because it might blow up.
