Way too much down time.

Ok guys I've been spending way too much time in my lazy boy. My breathing right now is not right. Always taking deep breaths trying to get enough in. The Drs. have me on steroids, antibiotics, inhaler and decongestant. Doesn't seem to have helped much yet. So tonight after I got home from church I'm setting here and I get this thought. I have a japchester 92 short rifle in .44 mag. I really like rifles with half and 2/3 magazines and I want to put a tang sight on it. So I go get the rifle out of the safe and start looking it over and checking things to change. I plan on removing the tang safety. It looks like it will be easy to make a blank and put into the safety slot with a screw from under the tang to hold it. Next I would like to swap the hammer with one that has a half cock notch. Does anyone know if an original will fit? I can always make one but it would be easier and quicker to buy one already made. I know how to take care of the rebounding hammer and that will go. Which after writing this I just realized that means I will have to modify the old hammer or change over to a flat spring. I need to find a new magazine tube so I can keep the one on it now untouched. I plan on making a blank to fill in the mag hanger dovetail. I made a new butt stock with a shotgun butt profile which made shooting the 44 mag more pleasant than the crescent shaped one that came with it. However I lost it in the move and can't find it now. I have another one started and may put a pad on this one instead of a steel plate. I have no idea what kind of screws they used for these rifles but all have super fine threads. The tang bolt looks like a 12x60 or maybe 70 threads per inch or what ever the metric version would be. I really need to get over this bug so I can quit coming up with ideas like this.

Sounds like your body needed a vacation, but your brain just kept on working...

Most of the time I'm thinking up ideas for a flintlock and writing notes and making sketches. But today its been lever rifles.

I'm not sure the current crop of Japchesters are like the 2008 and prior ones but... You should be able to simply remove the mainspring strut and use one like this:

That would be item #45, and simply use the top groove in the back of the rebounder's hammer. I've done this to set up several top eject mdl 94 guns that I'm in the process of building from bare receivers. I believe the same parts fit both a '92 as the '94. But it certainly shouldn't be problematic for an "artist" such as yourself to scale it up or down as necessary. I tried to get a machine shop to make me up several, but found their cost to be prohibitive!

Oh yeah, we'll need pictures of the work in progress and upon completion... no?

I'll try to post updates as I go.

I haven't tried it on a tang safety '92, but I did modify my tang safety '94 by replacing the rebounding hammer and lower tang assembly with 1981 vintage parts, giving me a traditional half-cock safety. I removed the safety switch and filled the hole by gluing in a piece of white micarta (imitation ivory). I was going to have my wife scrimshaw my initials on it, but decided something more generic might be better. I haven't made up my mind what that might be.

I recently bought a fancy new Limited Edition Deluxe 1886 Winchester takedown that had a tang safety. As is typical of the tang safety system, I got a good 20% misfires. I cured it by replacing both the hammer and trigger with Browning 1886 parts and modified the tang safety to clear the Browning hammer. The safety can be used to block the hammer from cocking, but I just ignore it.

It seems to me that if tang safety '94 and '86 rifles can be modified, the '92 probably could also be modified.

It won't be a problem to modify. I can probably do it in an hour or less. But I hate the hammer with that big notch cut in the side where the safety engages. I've been trying to find an old Browning hammer but no luck so far. I can make a new one myself but that takes time that I don't have right now. I removed the hammer and looked at it a couple years ago and if my memory is true I can put a half cock notch in it. The rebounding spring is an easy fix. However my rifle has not had any miss fires so far. Probably just jinxed myself writing that. Soon as my breathing gets back to sorta normal I have to hit the forge and get some serious gun building going. Gun building for paying customers not my own.

Was feeling a little better today and after doing some paying work I pulled out my 92. Only took about twenty minutes to make my stock hammer into a half cock hammer. Had to modify the sear along with filing a notch in the step of the hammer but didn't have manufacture any parts. Removed the safety but didn't make a filler yet. Also made a new mainspring strut and popped it in to see how it worked. Needs to be tuned up some, didn't polish it just filed it up. Didn't want to put too much work into the strut if I got it a bit short or something else that meant I would have to start over. The strut has taken the most time so far. If things go well I might have time to polish up the strut and try it out on some steel targets this week.
