Title: J-B bore paste
Post by: grampaj on March 24, 2014, 08:17:02 PM
I've read that you don't use bore paste on a airgun. I decided to try it on my marauder an this is the group I got at 30 yards with cphp 14.3. Before I started the barrel looked rough inside an my group was about the size of a quarter with some flyers.

I use JB Bore Paste on every new barrel the first time I have it off the gun, followed by Bore Brite....

 I too, use it on every airgun i buy. It has never hurt one, but has helped MANY, removing rough spots and allowing use of pellets they once hated. I consider JB paste to be a secret weapon  . ;D

Count me in here too. Every barrel that leaves the shop gets a minimum of a polishing with JB Bore followed by JB Brite. Be it PB or AG

Have been doing the J-B thing on every gun I have owned in the last 30 years except for a Tikka .243 I have. It has the slickest barrel I have EVER seen on a gun and shoots everything I put down the barrel well. Just did my AA S200 even though it was shooting good. Don

I've been wanting to try lapping the bore of some of my rifles.  Is a mop a good way to apply the lapping compound?  I don't quite follow how I would go about using cleaning pellets to do this.  I've only heard of using them for fire lapping.

Also, I understand the importance of using a freely-spinning cleaning rod.  Any recommendations that don't break the bank?  A Tipton carbon fiber rod (http://www.amazon.com/Tipton-22-Caliber-36-Inch-Cleaning/dp/B000BY56FO/ref=sr_1_1?ie=UTF8&qid=1395717903&sr=8-1&keywords=cleaning+rod) says it has twin bearings like cooter472 suggested but before I drop over $30 on a cleaning rod, I figured I'd better ask if there are less costly options out there that would work just as well.

Maybe Mothers brand metal polish? - look in automotive.  I used that for my $.25 Glock trigger job.  As far at that goes, I've used it to polish plastic watch crystals - so it's fairly fine.

Post by: SeanMP on March 25, 2014, 09:18:43 AM
Okay so the deal with JB is it's a friable abrasive. This is critical. What happens is pieces of abrasive imbed themselves into the steel of the bore. The friable abrasive will crumble. All the alternatives do not crumble. If you want to make your own I would suggest rotten stone and oil as being a viable alternative.

As far how long a 3/4 oz will last. I have a 2 oz jar. I sent a 1/2 oz to bob. I have been using the remainder for two years and I'm a shop.

$30 for a rod handle is reasonable. I wouldn't be inclined to prefer carbon fiber though. Ideally you want a rod which is harder than the bore steel. The odd thing about lapping is the soft material wears the hard material. This is why we use lead as a lapping slug. I make my own handles but only because I have the ability. What you absolutely don't want is a rod that is soft enough for the abrasive to embed into.

Cleaning and polishing a bore with JB is very simple ( your not lapping, this is a more involved process)
Run an oiled patch through the bore to remove any loose grime
Smear a tight fitting patch with JB Bore and add a few drops of oil. Starting from the breech end if at all possible run the patch full length once. Do not let the patch leave the muzzle. Set up a stop in front of the muzzle. (I position the barrel almost against the wall by securing it in a rotating vise)
After one full length pass go in 1" and out, 2 inches and out. 3 inches and out proceed like this until you have progressed all the way to the muzzle. Your patch will be black and ragged. Coat a new patch with JB bore and repeat.
For a polish job I'm happy with 100-200 strokes. A good sign is the patches won't be torn up once the bore is smooth.
When your happy proceed to clean the bore with fresh patches and oil. Do NOT use solvents of any kind. The last thing you want is to remove the oils from the pores of the metal. This promotes leading. You will probably notice a big difference in the feel of the cleaning patches going down the bore
Once your cleaned up proceed to Bore Brite if you choose to. This puts on a high polish that will make a huge difference in future leading and clean up. Use full strokes to polish but again do not let the patch exit the crown.

After a few hundred shots use Bore Brite to clean and polish any leading. Repeat with bore Brite as often as you like. A well seasoned bore that is not stripped of its oils or scratched with a bronze brush will eventually become almost impervious to leading.

Yup there is always opinions on both sides and Bona Fide experts to back it up.

I know some top barrel makers as well, as well as the a couple F Class Champions and a pocketful of competitive benchrest shooters that all swear by the stuff. I use it daily and I put out PB and AG barrels.

Of course you can give some people a string and they would figure out a way to ruin a barrel with it. As with any tool or product. It is either a gift or a curse depending on the hands that use it.

Been using the jb for several years also on ag's and along  metaphoric ( wrong spelling ) oil  with great success. I have old nylon brush ( no brass brush for me ). I go no more than 10 in and out pass of jb follow by the met oil than clean patches.
Some help me with the spelling of the metaphoric oil.
Title: Re: J-B bore paste
Post by: Greg_E on March 25, 2014, 11:52:58 PM
What happens to the crown if you run it all the way through? Is this why some barrel makers love people wrecking their barrels with it?

And thanks for the thorough write up, think I need a different cleaning rod, only thing here is aluminum.
Title: Re: J-B bore paste
Post by: SeanMP on March 26, 2014, 12:47:04 AM
What happens as the patch leaves the muzzle it's no longer compressed by the bore and it expands. That will cause a bell in the muzzle. The exact spot where you need the bore to be the tightest and the truest. In a perfect world the muzzle is absolutely flat and absolutely square to the bore. It sounds easy but it's something benchrest guys spend a ton of time perfecting.

I'm sure this is one way you could spoil a barrel but it wouldn't be terminal. It would just require the crown to be freshened up.
I think one of the biggest problems would be a guy who was a bit careless, armed with an aluminum rod well smeared with JB and and grime, driving a patch in from the muzzle without a crown saver and taking extra effort to grind the rod against the bore on every stroke.

I know this sounds silly but it happens daily. It takes me about a minute to measure this with plug gauges when a "bad" shooter comes into the shop

SeanMP - is there a cleaning rod you'd be comfortable recommending for .177?  I'm seeing aluminum, brass and 'coated', none of which I'd consider harder than the barrel.  If I'm going to do this, I want to do it right :)  Would you have/use a patch loop for .177?  Any other suggestions/recommendations?

I have the same question regarding a good ball-bearing rod for .177 cal.  Tipton claims the carbon fiber rod to be non-embedding and I was about to drop $30 for it but Sean cast some doubt on that claim.

I came across a line of Brownell-branded rods made of stainless steel which have a ball bearing (not clear if single- or double-bearing) so I will continue to research and read reviews but if the experts here know of a good choice, I would love to hear it.

Ya if you follow that link to Nikkonos that I posted earlier in this thread you'll find a very good rod for .177. In fact it's the only commercial rod I use. (pic 1)

 All of my other rods are made from a piece of O1 Drill rod ($4 ish from Fastenal) that has been drilled and tapped 8-32 or 10-32 depending on the caliber. I attached two pics of an example showing the handle, bearing, collar and bore guide (pic 2 &3)

Or Hoppes makes a solid stainless rod with a crappy handle. I was given one (they are about $14.99) and I yanked the handle off. Fitted a couple small bearings with loctite retainer and then siezed that into an aluminum handle with more loctite retainer. My total investment in this one was about $20 if I had to buy the rod....but it doesnt work on .177 (pic 4)

I could be completely wrong on the carbon fiber thing. It just seems to me that being a bundle of fibers bonded together by epoxy that particles could easily get trapped in the fibers. We're not talking about very big particles. I use abrasives that are 6 microns to lap a crown...pretty tiny

I know the coated ones were proven to be bad news. A guy took a bunch of pictures under a microscope and it looked like a rasp. Of course that would only be the soft coated units. The ceramic ones are essentially impervious but the are so fragile.
Title: Re: J-B bore paste
Post by: nervoustrigger on March 26, 2014, 11:58:11 AM
Yeah, I agree.  It makes total sense as to how such tiny particles could embed in carbon fiber.  Meaning, I have my doubts also...and also could be completely wrong :).  But based on your experience, I'll probably go with the rod you recommended.  All my rifles are shooting well so I'm just looking for incremental improvements.  Mainly just concerned that I choose a rod that minimizes the risk of making them worse.

If you got a barbed jag like the one in the pic it will work just fine.

The only other tip I can give you is to slobber the patch up with plenty of oil. Like an oil stone or whet stone the oil helps the abrasive work by floating away the swarf

Yupper, pretty much looks like the pic :)  Now I just need my JB and some time.  I anticipate removing my Disco's barrel, securing it vertically in my Workmate, with the muzzle resting on a piece of wood.  Then 'lapping' as you had described.  I'm hoping it will improve accuracy/consistency some - get rid of the occasional flyer that's a bit away from the main group... at least I don't think they're my fault  ::)

 I would suggest going to the GTA library.
- Some great info on barrels lapping plus more etc..
- I know some Air rifle barrels are choked if you push a .177 pellet through barrel from breach you can quickly feel the thick and thin of it. I even cut a barrel off because its last inch or 2 was  loose and I could never find an accurate pellet for it. I did lap the barrel some (jb bore paste)
its now perfect and very happy with outcome.

- I have treated all my air rifle barrels differently to any powder burners because I never thought it was the same metal, rifling, heat, pressure or anything? and I think lead is needed for them to perform I would consider a mild cleaning after 20,000 shots maybe or something is wrong. just my opinion.

I saw this on GTA link-

I really can't see worrying about the non embedding paste and then turning around and using a boons brush. the bronze burs is a Phosphor Bronze,and quite hard.


couple with the fact that the paste will simply be moved around the bristles, and accomplish near nothing using it with the brush, what is the point?


Why risk an ag barrel with a bronze anything. I you simply have to use an attachment rather than the recommended jag and patch, at least use a
bore mop with the paste rubbed in. LOL!


I you don't want to do more harm than good, or accomplish  anything at all, follow recommend procedures, or leave it up to a pro.


If you don't really have a handle on what you need to do, Don't do it until you understand the mechanics of the procedure.

I prefer http://stores.ebay.ca/Olympic-Marksman-Equipment/CLEANING-PRODUCTS-/_i.html?_fsub=4005340016&_sid=53339476&_trksid=p4634.c0.m322 (http://stores.ebay.ca/Olympic-Marksman-Equipment/CLEANING-PRODUCTS-/_i.html?_fsub=4005340016&_sid=53339476&_trksid=p4634.c0.m322)

Sorry for the thread revival.  I'm confused about the rod suggestions.

I read the above quoted post several times, and this entire thread a couple times.  I am still left with the question:  Is there a commercially available rod that is made out of the correct material to use when polishing with J-B bore cleaner and bore bright (that is within the US)?  If so, what is this rod, and what is its material (and perhaps a manufacturer suggestion)?  I do not have access to a lathe to make my own handle (with bearings, and the rod out of drill rod).

I *think* a stainless rod was suggested (via a link to a Canadian ebay store).  How about a J. Dewey stainless rod in the appropriate caliber?

Yes, pretty much any reputable brand of cleaning rod will do...Dewey, Pro Shot, etc...so long as it has ball bearings in the handle.

Provided you will be working from the breech end as recommended, don't fret over the rod material.  Stainless steel, carbon fiber, whatever.  I even used a brass one for a few years that I had converted by threadlocking some inexpensive ball bearings to it, similar to what you see in this picture:

Then I made a handle for it with a piece of 3/4" dowel.  It was a simple project that I was able to do without a lathe so I figured it's worth a mention.  But for most folks, just plunking down the $30 for a decent commercially made rod is probably the better option.  If you're interested though, here's a brief writeup

For those interested, you can buy diatomaceous earth very cheap & make your own compound by mixing it with some silicone grease to desired consistency. Diatomaceous earth is used as a fine silver polish & works great.

Would the diatomaceous earth be a substitute for J-B Cleaning (blue label), or J-B Polish (red label)?

I ask because it seems covid has consumed all the red label polish.

From what I’ve read, DE is an equivalent grit to the original gray J-B.
