Miroku 500 Charles Daily Top Lever Removal

[sean69]

trying to get the top lever off a "Miroku 500 Charles Daily Top Lever Removal" .... is there a trick to this? I'm not 100% convinced that it is actually a screw.

the slots are VERY narrow, I've had to grind down a couple of screwdrivers to fit properly and no dice moving it at all. Been hitting it with penetrating oil for about a week now... still no love.

is it actually a screw(well bolt I guess)? is there a trick?

-thanks

I think that is the same as a browning bss - maybe easier to find info on the bss. Sorry I can't help more than that.

Whoa, I thought the 500 was a sxs not a o/u.

It is, there is one sitting in my safe.

 

[sean69]

yea - wrong gun!

Which one? Are you working on the o/u shown in the schematic shown above, or the 500 sxs?

Yes - I tried to find a schematic on gunparts ... I also came across an article that stated there were no schematics for Miroku guns. (here: http://www.leeroysramblings.com/Firearm Related Articles/Firearm related articles.html)

The Browning is VASTLY different - far more complicated - this little Japanese thing is quite simple in comparison.

That's too bad. I was under the impression they were virtually identical. Sorry for the bum lead.

are you trying to take the whole lever out, if so remove the spring will take some pressure off maybe, and a really good quality screw driver, ie gunsmith drivers not Canadian tire ones

The receiver is currently completely stripped EXCEPT for the top lever - I'm a big fan of Grace screwdrivers. I had made a couple of specialty bits from some O1 tool steel, but they didn't fare much better.

If I could find a replacement screw I'd probably try an impact driver and/or drill it out + screw extractor .... but can't take a chance on damaging the screw unless there is a replacement on hand

GOT IT!!!

thought I would try a cold chisel ground to profile - to a file to it and too soft ... then I remembered a couple old chisels from my uncle's tool box... grabbed one of them ground it to the exact profile and the screw just popped loose!

Glad I kept passing over the impact driver!

Good job with the chisel, I probably wouldn't have thought of that! Minimal damage to the screw slot too.

Actually no damage ... that is what I was working with to start ... a couple swipes with a needle file and it will be good as new

I'm surprised too - generally in my shop chisels start at around $40 so grinding one up for a single use isn't generally an option.

I'm also quite surprised at the quality of the steel in this chisel - I might just grind it back to profile & start using it (well, after the action get polished and put back together)
