I am wanting to mount a Pachmayer Lo-Swing scope mount on a SS hardened receiver. Does anyone know a good source for carbide drills and taps?
Thanks in advance!
Thanks in advance!
Boy now there's a tip I missed. In addition to what I posted above, another factor in my past successes has been the use of Rapid-Tap. I bought a distributor out of it when it got outlawed in California and am still using up my copious reserves to this day.It won't cut because you are literally forge welding the tap to the receiver. The tap displaces the chromium oxide layer and as it reforms due to oxygen exposure it traps the tap. You need an appropriate cutting oil that is high in sulfur content. It will prevent the oxide layer from reforming until the tap is removed.
RUGER
MODEL STAINLESS STEEL MINI-14 RIFLES
RECALL: Ruger is recalling all stainless steel Mini-14 rifles with serial numbers below 182-51929 with only one proofmark on the receiver.
We have examined a total of three stainless steel Mini-14 rifles that have been returned from users with cracked receivers. In every instance, this situation was traced to a combination of two factors:
The receivers exhibited excessive hardness; and
The rifles were fired either with an obstruction in the bore or with faulty ammunition creating extremely excessive pressures.
Not all stainless steel Mini-14 rifles have an excessively hard receiver. Every Mini-14 ever shipped, like other Ruger firearms, has been proof tested. We cannot tell which ones are too hard by serial number alone. Therefore, we are recalling all of our stainless steel Mini-14 rifles below serial number 182-51929 bearing only one proofmark on the receiver for inspection, testing, and re-heat treatment, if necessary. Most rifles will require only a Rockwell test and will be returned after testing. Rifles tested will be given an additional proofmark. Only some rifles will require re-heat treatment.
Remove the buttstock from your rifle, and remove all custom accessories. The remainder of the rifle is all that we need. Securely package and insure your barreled action, bolt, trigger housing group, and handguard (a shipping carton is available upon request), and ship it UPS AOD to:
