Here's something I posted on another board seven years ago:
"Rock Dust & Weeds: 9 Shot Ruger SA .22Mag
Friend of mine got a used one a few weeks ago. He wanted me to go with him to a farm he owns to shoot it. He's crippled so he likes to have somebody along to open gates, staple targets, etc. He can get around but it's hard for him. I get to shoot a little of his ammo & try his guns.
He fires one or two cylinder fulls through it and then I noticed something is wrong! Lo and behold! The ejector rod is jammed!
He's starting to get really ticked off. I yell at him (we're wearing muffs) to wait and let's see what's wrong. (Later tells me if he had a hammer at hand, he might have broken the gun!)
So I take the gun over to the table (my friend normally shoots from the driver's seat) while he picks up a .22LR Ruger SA.
Now I'm not a gunsmith; 'nor do I play one on TV'. What was it good looking women used to say to me before I got old? Oh yeah: "In your dreams!"
Oops! Off topic! Nevermind.
Rod is still jammed, as I take the cylinder out. Then pull out the Farmer Model Victorinox (one of the Swiss Army Knife models) my friend gave me for Xmas '85 IIRC. Used the smaller flat tip on the can opener to carefully remove the housing screw.
Hmmm, only a little firing debris and no burr(s). Plenty of lube. Spring okay. Housing straight and smooth. Rod straight and smooth except where the tip has been peened a little against the cylinder face (but that's not the problem). Hole in side of frame looks good (both larger and smaller diameters). In fact the smaller which the rod goes through just before the cylinder is obviously greater than rod diameter.
Get to playing with it. Stick the rod through the frame hole from the front and what the heck? The frame rod hole is as rough as the proverbial cob! Towards its front at least. I can't see it, even in sunlight with my glasses. Sure do feel it!
Now what can I do? No abrasive paste or tool(s) to deliver it. Hey there's lots of limestone around here. And there are these stiff tall dead weeds. Being dry and porous, the weed ends hold oil and dust, yet are still stiff enough.
Find a couple of rocks and grind them together. Break off a long piece of weed thin enough to fit the rod hole. Square the end with knife blade. Wet the tip with lube from housing and charge with limestone dust. In retrospect, oil from the dipstick might have worked better to hold the dust.
Finally start working the rod hole for maybe half a minute or so. Then rewet tip, recharge, and start working again. Did this at least six times IIRC. Sometimes had to recut the tip. Kept retrying the rod in the hole until I could tell it was smooth enough. Use a burger chain napkin to wipe any remaining dust out/off and reassemble. It works! Could be smoother but NO more jamming! Shot several cylinders full through it and cases were ejected just fine. The jamming may have been why the gun was traded in.
When we went back to his house later, I got hold of some toothpaste, Q-tips, and a cordless drill. Charge tip, chuck in drill, then work the hole again for 10-20 seconds. Remove, get new Q-tip, repeat for maybe eight times, checking with rod through hole each time. Finally clean with alcohol, reassemble, relube. Much smoother now.
Mutual friends get a chuckle hearing how I fixed his gun with rock dust and weeds. Hope y'all do.
Oh yeah when we were at his house, I noticed the ejector housing is sharp edged on both sides of the slot, especially the upper edge, which is cutting/gouging the rod handle. What I have been using is insufficient to dull the edges. Since my friend is too cheap to pay a 'smith, does anybody have a Dremel?"
