That's when you invite a friend over for a beer. After he has had a sip ask him to hold the B&O, make sure you tell him that it will only take a minute and it usually doesn't hurt.

Well, it would have to be more like generic peanut butter sandwiches on "firm" bread with tap water.

No wonder I have no friends anymore.

Do ya need to remove some pins? Maybe I can borrow a B&O from work and come give you a hand.

Actually Ed, I'm just starting to get my ducks in a row for the various things I'm gonna need to do to repair & restore the backhoe and add the hydraulics to the thumb. After a couple of "schedule setbacks" today, I am sorta back to the budgetary stage... and rethinking my whole approach. I'm guessing I won't have all the parts and tools in hand for at least 2-3 weeks... and some stuff may have to go out for repair as well. In particular, bucket tooth replacement and cutting edge restoration may be something better left to the pros.

But thanks for the offer. Right now I need more information than actual hands-on help.

Dougster; I happen to be in the aircraft industry and that is what we call a rivet set. There are many styles.

The "AIR HAMMERS" we use which are called rivet guns are a little different but do the same thing with allot more control than just on or off and it shows in the price.

There are several different sizes of rivet guns and I guarantee you a 9X rivet gun will knock out a very big rusted/corroded in pin/bolt.

A rivet gun has many advantages over a big ol sledge hammer, it will give many hits to keep the pin/bolt moving, also with repitious hitting it can break loose the bond the rust/corrosion has on the fastner as opposed to one big whack.

I have three rivet guns, a 2X ( 2" stroke)for small stuff, and two 4X (4" stroke) guns, I keep one at home for many various jobs from busting ball joints with a fork to knocking out frozen bolts.

A rivet gun to me is a valuable part of my tool choices for the right job.

Interesting. So I assume you think this hammer bit would work on those various nasty backhoe pins? I hope it will... and for the money it's clearly worth buying and trying... but I am concerned that the relatively small weight/mass may have a tough time.

I understand the value of impact. Just ran into it the other day when my GF couldn't get an oil change at Valvoline 'cause her drain plug was frozen. Even with breaker bars, the pit kid couldn't get it off. She brought the car to my place where we knocked out that plug in exactly 1 second with the small air impact wrench on low power.

But can the same "air impact" approach work on those big nasty pins?

I guess we find out sometime next week.

Sometimes, the impact can make all the difference in the world.

I have one (aircraft sheet metal mechanic as well) that has a brass tip on it.

I only have a 3X gun, but I do have an older long stroke CP air chisel that has substantially more force.

I use it for stuck pins a lot, Often times things like aluminum motorcyle swingarm bolts, etc. etc. Sometimes we couple impact, turning, heat and oil to get them to break and start sliding.

If you want that type of tool I would reccomend you go here.

The Yard Store, Aircraft Tools & Aluminum

They have a very wide selection and good prices.

All that said, for my backhoe (1.750 pins I think it was) it is a large dead blow coupled with a big drift, and then my son manipulating the controls to insure I have no load on the pins.

OTC (Ottawana Tool Company) makes various pin pullers and presses for the really stuck ones.

I would go with the Chinese versions out of HF, but I know how you feel about the Chinese stuff.

Interesting info and link Alan. Thank you. Not knowing any better, it sounds inherently funny to me to use aircraft tools (think: lightweight metals) on a backhoe (think: heavy steel)... but I guess you guys know what you're doing. I don't understand the 3X, 2X, 4X thing (and how they might compare to automotive-type air hammers), but I will assume it has something to do with stroke and/or power level.

Since I already have the automotive air impact hammer, I'm gonna stick with that Old Forge #1981 flat-faced bit for now. In fact, I put in the order this morning. We'll see how that works out and take it from there. Had to go Internet order as no one around here carrys them. God bless you guys who have decent specialty tools stores located all around you! Even my nearest HF is a L-O-N-G ride away down into Rhode Island.

And yes, I love my American-made tools and practically everything else. I know it is a losing battle in year 2007... but I WILL go down kicking, screaming and fighting.

Whatever I can still buy American-made, I always do.

The 2x etc. refers to the size of aluminum rivet it is designed to set in 16ths of an inch.

Ie a 3X gun shoots (upsets) a 3/16 (or a -6 just to keep it confusing) rivet.

That said, as a statement, smaller number, lighter hitting gun.

I think if you have a "standard" short barrelled air chisel, you will be spinning your wheels, unless you just want to shake it to get the oil to penetrate.

Good, heavy duty, long barrelled, (longer stroke) hammer, and it may make something move.
