Hi Again:
While working on a Mauser 98 equipped with a Buehler nee Timney, swing safety, I noticed a very small set screw and coil spring "appeared" on my work bench. These are about 1/16" in diameter. There is a tapped hole on the side of the shaft that will accept both the spring and the screw.
My questions are: does the small coil spring and screw both go into this hole and if so what function do they serve? I would like to know what purpose these two thing serve as I can not see any reason for them to be there unless they are supposed to take up any slop in the shaft to bolt shroud clearance.
What are the odds of me losing one or both of these very small items? Lol
Any ideas?
Tia,
Franchi

IIRC you need to be looking for a really small ball bearing also. I would have to check the ones I have in packages for future projects, but I believe there is a spring and ball bearing.

Franchi: They are for holding the safety is a locked position in a small detent. Call Timney they will send you another free. They are good about that. If you do a lot of safeties, I suggest you do what I did and but a small supply to keep on hand. Be aware the safety requires careful hand fitting and does not just replace the military one. Good Luck

The spring in the Buehler safety rod is intended to dampen the slop of the wing, providing tension and thus resisting any up-&-down loose motion when the safety is 'OFF'. The Buehlers I've seen have had no screw or ball bearing in the rod's hole; actually the only screw I remember is the one that holds the wing to the rod.
I've had one FN-style left-side wing safety with a tiny ball bearing partially pressed into the rod to dampen movement, requiring some force to push into the bolt sleeve. It had a tiny detent hole inside the rod's longitudinal bolt sleeve hole, to further restain the safety in the 'ON' position. NEAT idea, I've never seen it used anywhere else. Regards, Joe

Hi:
I called Timney and the chap to whom I spoke, had no knowledge of the safeties. He did tell me that he would send me a spring and set screw.
I have no idea as to how these things work! There is a small spring, set screw, and a tapped hole that will accept the set screw. If one places the spring into the tapped hole the set screw can be screwed into the tapped hole. When I first saw the three pieces, the spring was sticking out of the hole in the wing of the safety and the set screw was lying on my work bench where I had just taken the wing out of the bolt shroud. This led me to believe that the set spring was meant to hold the spring captive in the shaft of the wing. I do not think that there is any detent and the spring is intended to take any slop out of the two pieces.
When the safety is in the on position, there is quite a large amount of friction holding it in place due to the pressure exerted by the firing pin spring on the cocking piece that is against the safety.
When the safety is in the off position, there is no place that it may go except to be turned to the on position when desired. It just 'floats" in the off position.
Any other ideas as to how these things function and how they are assembled?
Thanks in advance,
Franchi

Do you have the installation instructions? If not they are available on the Timney website.
Having said that, you may want to consider some personnel assistance as in going to a gunsmith for their review of the issues.

Hi Alvin Linden et.al.:
Thanks for all of the help!
I may hae to stop in at my local gunsmith to see how this Buehler saftey goes together! The tapped hole with the set screw is the real mystery!
Stay well,
Franchi

Franchi: I have never installed one of these safeties that it did not require grinding to a "degree" on the safety to get it to smoothly go on and off. It is better to let this job be done by a gunsmith until you are familiar with the principals of the operation of the camming surfaces and their interaction with one another. Grind wrong and you can throw the safety away. The adjustment screw and spring are used after the correct grinding, to adjust the tension on the lever. HTH Good Luck Jerry
