The incredible bobby pin trick
« Reply #1 on: August 14, 2013, 09:54:01 PM »
Chances are, you have a member of the Fair Sex living in your house. (Why they call them the 'Fair Sex' is beyond me.....nothing they do seems fair, but I digress....) If so, there is a Very Good Chance that they use Bobby Pins..those aggravating little metal hair pins that we used to make 'snappers' out of as kids. Well, now you can have your revenge on the Fair Sex.....steal their bobby pins!
What?!! Cap'n Gone Mad?
Why, no. Cap figured out that you can use Bobby pins to replace the broken hand spring on your Colt!
Yep...done it on two of my Colt repros to date, and they work just fine!
Here's the thing; the bobby pins may not be the same thickness as your old hand spring, so here is what I do:
1) Using a very thin-tipped screwdriver or other thin tool, place the slot of the hand over the slightly open jaws of a vise and gently tap out the broken-off piece of spring.
2) Cut a piece of bobby pin and bend it in a question-mark shaped piece. Leave it a little long on purpose.
3) Drive in your new spring. It will be snug, but move side-to side.
4) Rather than bend over the hand slot, lay your hand and spring on a brick. Using flux paste and rosin core solder, heat up the area using a solder gun  and allow the solder to flow into the slot, securing the spring. This will hold it fast, but allow you to replace it easily next time it breaks.
5) File off excess solder using a hand file. Do your final bending and contouring of the new spring and trim it to correct length using diagonal cutters.
Oh...and when finished; grab a handful of those bobby pins and throw them in your possibles box. She'll never miss 'em!

Quick-n-dirty trigger job
« Reply #2 on: January 17, 2014, 09:00:52 PM »
OK, so you are headed out to the range with that new-to-you Pietta Colt you picked up....one problem, though. The trigger SUCKS!!!! Here's how to clean it up without turning a screw...
Hold the gun in your right hand (assuming you are right handed). Now, squeeze the trigger. HARD.
Maintaining that squeeze, thumb the hammer back multiple times (like 20 or 30). Now, holding pressure on the back side of the trigger, repeat several times. Now, cock it normally. Feel a difference? That's because you knocked off some of the burrs in the hammer/trigger area. This is no substitute for a good stoning job, but it has helped make some horrible triggers I've encountered until I can get at 'em proper.

If you are bothered by a small screw that wants to keep backing out in use, rather than investing in a bottle of LokTite ($$) use a drop of fingernail polish on the threads.

Another trick to keep screws from backing out....put a short length of fishing line in the threaded hole, then turn the screw in, snip off any excess line. This is kinda like the nylon inserts in threaded nuts.

Why not just put the screws in and then tig weld them?  L@J ).L

Works great if you NEVER need to take the screw out! It does take a fine touch though.

hand spring fix.  try  using a coping saw blade.  trim, sand polish all the teeth off.  and it works great.  have to bend it.  heat.  quench in oil.

trick.  I have an original 51 Colt 36 navy with a large cylinder/barrel gap.  I do not want to hurt the value of the gun..HOWEVER...

    I got a Thin washer from the hardware store.  ground it to fit Over the rear of the cylinder ,  over the ratchets,,,this pushes the cylinder
   tighter on the riding portion...look and you'll see it...

      I used a needle file on the shim I made to relieve it until the cylinder revolved perfectly.   The action became tighter, the gap is totally gone, and the
fix it not part of the gun.   It just takes up all the wear that happened in the last 130 years. 
    I toyed with soldering it it, or epoxy it in...but it works so perfectly, I'm going to leave it alone.
   Totally invisible too...
  Ken   here is the finished product...

Nice idea, Ken! Thanks for sharing it! I also like the fact that your fix is completely reversible for rare or vintage revolvers.

That's pretty slick Ken! Nice work bringing an old soldier back to life.

Do you plan to shoot it?

I would guess that fitting the washer would be a lot of unnecessary work if Ken doesn't plan to shoot it.   It might make it nicer to play with I guess.   
We could stand to see a few pics of the entire original Navy revolver if you get a chance to post some.

and  here is the Navy with the shim in the cylinder.  by the way, this caused the bolt to hit center again, and the action is smooth and very tight.  and..Colt shimmed the hammers on Navy's all the time.  not an unusual practice...
