cost for throat reaming

[sixshot]

Anyone have a ball park price for reaming cylinder throats on Ruger 45's, to .4525".

$30 plus $12.50 insured return shipping for ream throats to .4525" and finish with standard 180 grit brushed finish, $48 plus $12.50 insured return shipping for ream throats to .4525" and finish with lapped and polished 400 grit finish.

180 grit brushed finish:

400 grit lapped and polished finish:

man, wish I knew about the 400 grit polish when I had you do my last one!

[DougGuy]

Send it back! I have just recently put on the tooling that does this in the last 10 days.

Soon as I get mine, Ill be a stuffing it in a box and sending out

too late, already went at it with a brass brush wrapped with a wipe and JB bore paste chucked in a drill. Doesn;t look quite as nice as that pic, but much much improved (from a tooling mark perspective)

It is very very difficult to cut Ruger cylinders cleanly. They are TOUGH and the metal pulls and tears out even with a brand new reamer. About all you can do is use cloth backed abrasives and blend in the marks the reamer leaves behind, or use a smaller reamer and a lap and laboriously lap the throats out until they get to size. You don't necessarily want to remove all the marks, you want them small enough and fine enough that powder and lube residue will fill in the voids. If you try and sand out all the marks, your throats will then be oversized and likely not very round either. Cylinder throats are not rocket science, but there ARE some do's and dont's that one needs to be aware of beforehand.

If I wanted to invest a few thousand dollars in a Sunnen hone, I could do them better than the factory ever dreamed of doing them, but then the cost would be pretty steep, easily over $100 for one cylinder. For the quality of work that I do, even at the $30 level, you get an immediate improvement over what the gun was capable of, and if you let the residue fill in the hatch pattern that is left after reaming, you can't tell the difference in accuracy or performance over a finely honed throat that cost 4x as much to do.

My own Vaquero never even got honed or polished after reaming, it has the tool marks that the reamer left, and it doesn't lead, it filled in to a seasoned finish not unlike a cast iron skillet after a few years of use. You get what you pay for. If you want a finer finish, I can do that, but I won't sacrifice the accuracy of the finished work just to make it look smooth. Like I said, it's not rocket science but you can bell-mouth a cylinder throat in a HEARTBEAT if you are not careful.

The one Doug did for me was not polished, (nor do I expect it was from the factory), but it was right on spec, and shot much better afterwards. I am entirely pleased with an "as reamed" cylinder.

Yours was honed with cloth backed abrasive. I don't call it "polished" but I send them with a brushed finish. Mine is the only one that I haven't cleaned up after the reamer.

Great salesmanship there Doug ;) It's good to see the honesty though. Whatever you did, it made a big difference. I know who I will go to the next time I need this work done.

I too had a Ruger reamed to 0.4525 some months back. Now if I can figure out how to remove cylinders from S&W revolvers, I'll be sending a 357 and 41 mag his way.

Easy, take out the sideplate screw farthest towards the front of the frame. (Muzzle end). The yoke and cylinder slide right off of the frame.
