Left handed sear help

Post by bunkyz52 » Fri Aug 23, 2019 3:36 pm

Hello everyone. Once again I've been in the hospital with an unhappy heart but, lol, I refuse to give up. Now that I'm back home I'd like to get some stuff finished but I'm afraid I'm gonna need some help. I started a present for my wife a few months ago that I call Ebony and Ivory. It's a back to back double with one side having ebony scales with an ivory button and the other side ivory scales and ebony button. I made an attempt to post a pix and I hope it worked. I'm down to the finishing touches but the last part I need is a left hand sear. Sorry to say I'm not gonna be able to make one cause for some reason my hands have started shaking and both of the two I've attempted to make haven't turned out to be usable. If there's anyone out there who either has one or is willing to make me one I'll gladly pay for your help. This is probably going to be my last build but it's the most important one I've ever done. If you can help me please contact me by either a post or my email (bunkyz52@comcast.net). Thanks in advance and happy building :D

If you are using pre-made pieces, your best option is to find a normal (right-handed) piece with a longer than normal sear. Then cut the ramped part off and put a new ramp going the other way (so it is now left-handed). You can get a little more sear length if you file the liner down where the button sits on it and file the ring part of the button's arm down. Be careful not to take too much off of either as they are load bearing parts.

Hello, thanks for your quick reply. Yes, I'm using the USA made sear from SwitchbladeKits.com. I've already modified two RH sears by using the trim at the opposite bevel method. Both are close but come up short and I end up with a hair trigger. I've also channeled out the liner under the sear to increase the depth of the sear into the hole in the blade and still end up with a hair trigger. Both methods should work but for some reason aren't. I've tried everything I know to try to this point. Lol, at one time I would have simply removed the penetration pin at the bend, reversed it and tig welded it back on and "problem solved " but I'm sorry to say because of health issues, shaky hands and being half blind that's not possible anymore.I thoroughly agree with your suggestions and know they work but under the circumstances it looks like my best bet is to pay somebody to to make one. Thank you so much for your help and ideas.

That is a good idea. If you could anneal the sear piece, bend it upwards, then bend the body to have the right shape, then heat treat it, that should work. If you want, I can try to make one of those for you.

Hello again "JB257". If you could make one for me I would be extremely grateful. Of course I will compensate you for your time and trouble, I wouldn't feel right if I didn't. Honestly right now I can't physically do it and it's gonna be at least a couple weeks before I can do much of anything. Luckily I'll be able to do a lot of the final assembly right here on the bed. Just let me know how things go and we can work out the details later. Thanks again for your concern. If you want you can contact me by email. I think I posted it earlier. I'll be talking to you soon. Lol, it's 1:30 here and it's my bedtime. If I don't get some rest I'll regret it tomorrow. Have a great night. :D

Hello everyone, I decided to give JB257's suggestion a try but I'm not having any luck. I've destroyed two perfectly good RH Sears in the process so I think I'll call it quits. Lol, my mother used to tell me you'll never know if you don't try. I've often wondered why no one makes a left hand. I bet with all the people out there who are left handed they'd sell out in a flash. Happy building :D

Hello Mr DeShivs, thank you for responding. I've tried altering Italian parts as well as American and every result has been the same. I've also channeled out under the sear to increase the depth of the pin and end up with a hair trigger or no hold at all. Maybe I'm missing something. I'm open to any and all suggestions. I must say your work is impeccable and I consider it an honor to talk switches with you. Thanks again

There is no difference in a left and right handed sear, you just have to mount to the other liner and put the sear hole in the other side of the blade, or drill the hole all the way through the blade.

Incorrect, Dave.
There has to be an angle on the sear to clear the spring and blade.
That angle is exactly the opposite on a left-handed knife.

Hey, sorry I missed your response the other day. I will try to reverse one. If it works you can have it.

Did you heat it up before bending the sear back?

Hi JB257, yes I did. Hard to describe but to an orange color. Like I was bending a piece of round rod. I guess not enough

Did they break or did they just become completely mangled when you tried to bend them back?

How did you make the sear work as a leftie? Did you bend it 180 degrees or did you just make the sear fall down farther and file the sear to go the other way?

No bend- just filed and milled the liner a little.
