Title: Problem with staple gun
Post by: Rich on December 30, 2016, 03:55:12 am
I have an EZ Fasten long nose gun that is misfiring because the driver blade will not fully retract to allow the next staple to move into the firing position. I've tried to find a rebuild kit for it with no success. The manufacturer, Central Fastener Co. Ltd, is in Taiwan and did not respond to my email contact.
Last year, I even sent it out to someone who claimed to be able to rebuild it and it still will not work properly. I'd like to be able to use this gun again, so I'm asking if anyone here knows what causes to driver blade to retract? Is it the O rings that are leaking? I can't see anything that would push the blade back up with enough force to overcome the pressure of the spring loaded staples pushing against it.
Thanks,
Rich

Sometimes the bumper has a groove worn in it, allowing the driver to sink too far and get stuck.

If someone tried to rebuild it there is no telling what was filed and whittled away, bent and straightened.

I put a drop of oil into the air intake every once in awhile. I think I had been putting oil in too often.

My gun did the same thing last year or so. I mentioned on this forum that I took it apart and cleaned all the built up oil out of it and it worked great. I add oil only occasionally. I think the gunk was keeping the driver from re setting properly.

I finished a major project last weekend that took just over 3 boxes of staples. Yes, that's a lot of staples! The driver began to not re set properly once and I gave it a bit of WD 40 and it was off to the races.

Try a bit of WD40 directly onto the driver and down the driver shaft, and if that helps the problem might be a sticking situation instead of a burr or bent or worn out situation.

Thanks for the suggestions.
I did lubricate the driver at one point and it helped for a few staples, then began hanging up again.
As I remember, the reason I had sent it out to have it repaired was that the driver blade broke. They did replace it with a new one and it worked for a while and then began hanging up.
I'm wondering what is supposed to bring the blade to a return position since there is no spring acting on it. I'm thinking it must be air pressure pushing it back up since it does need some force to overcome the pressure of the spring loaded staple magazine constantly pushing the staples against the driver blade.

I agree with Gene, that it is probably just a case of a good cleaning and a bit of oil. I'd strip it right down and clean all metal/plastic parts with solvent (I've even used naptha and carb cleaner in a pinch). If the O-rings are looking worn or bypassing air you can give them a light coat of petroleum jelly before you re-assemble. also check teh business end of the driver for any small burrs.

Having the same problem with a long nose.  So, cleaning with .........what then give it the oil?

I too was thinking about checking for a rebuilt kit and a driver blade.  The driver blade has small bit of metal broken off but it lasted for years before I did that number on it.

I don't mind the gun, guess most are built in Asia?  Those in the lower price range.

I never tried carb cleaner, clean the O-Rings with it also.  Don't think that has been done.

Good news! Encouraged by these posts, I decided to give it another shot (no pun intended) and disassembled the gun to see if there was anything I missed when I cleaned it up last time. Everything was clean, but I tried sliding the driver blade through the bore (piston with O ring at top) and found that it seemed to hang up near the top. I used some oiled steel wool inside the bore, but I think more importantly, I chucked the top of the piston in my drill press and used some fine wet or dry sandpaper to slim down the O ring. Put it all back together and shot about a half stick of staples with no misfires.

Now, I'll try it in actual use and see how long it goes that way. Maybe I fixed it? At any rate, I think I proved the problem is with a too-tight O ring.

Before the holidays, I asked someone I found online if he could get the replacement parts and he said he'd get back to me when he found something. Maybe he'll come through with the proper O ring.
Thanks for the help and Happy New Year to all!

Forgive me if this is slightly off-topic.

Why do you guys use long nose? I'm still learning/new(ish) to upholstery but I have yet to find something my regular gun wouldn't do.

I had a chair awhile back in which the groove was 1/4" but still the regular gun was fine.

65, A long nose is helpful probably 15 - 20 % of the time. It isn't to get into grooves as much as into areas that a normal gun would tend to mark up the fabric while getting to an area to staple. There are time when neither guns will get where you need to go but having a long nose is very helpful at times. I went for 30 years before I had a long nose. I would use tacks when I couldn't get my gun where I needed it to go. Tools are very helpful and Upholstery work doesn't really require many tools. So any excuse to have a tool is a good one LOL.

I've been thinking about this again. Nowadays, you can get almost any tool you want in battery operated form. Why not upholstery staplers?!?

You can now get narrow crown staplers, battery operated. Honestly, I'm really tired of this air compressor thing. It's a hassle and waste of energy. I guess the companies just don't see profit in building a battery upholstery stapler?

There are new gizmos and such for woodworking all the time. That's because there's a lot of woodworkers out there. Not so for upholsterers.

It seems all innovations in the upholstery world are for factory applications - how to make furniture faster and cheaper.

A quick google search and I saw a pneumatic staple gun weighing 1.8 pounds and a Ryobi battery staple gun weighing 5 pounds. That's a really big difference!!! My upper shoulder gets sore occasionally from my pneumatic staple gun. I can only imagine the amount of Advils I'd be taking with a battery powered staple gun.

I wonder if when the pneumatic stapler came out that upholsterers were complaining that tacks and a hammer weighed a lot less and the pneumatic stapler would wear out your arm.

Nope we loved it. Faster easier. My first stapler was electric. That weighed around a lot!.

I had one once. The batteries lasted about a year. When I tried to buy new batteries, they were no longer available. And the stapler was discontinued. I didn't like it anyway. It lacked enough power for hard woods.

The catch-22 with most battery powered tools is......... when it's time to buy new batteries, you can usually buy a whole new rig for $10 more.

You may think that a compressor is a hassle. But to me, anything else is a bigger hassle. Give me the compressor.

True. I only use my long nose for hard-to-reach places. But I know a lot of upholsterers that use theirs full time. They just like it better.

Ok, you got me there. I am just a very small one-man shop and compressor issues drive me nuts. I had a little senco, quiet devil, but had problems.
I curremtly have a 6gal porter cable that sounds like a freight train, but hasn't failed yet.
I know these things aren't meant to last forever, and I don't wish to use an oiled unit. But still..
Title: Re: Problem with staple gun
Post by: MinUph on January 03, 2017, 06:25:53 pm
  The only oil free unit I will ever own again is my portable one. They are just too noisey.

  As for battery tools, I had a brad/finish nailer from Dewalt that was very good. Heavy as a sledge hammer but it worked very well. I had it for about three years and sold it when I go out of the business for around 100 bucks less than I paid for it. Batteries were just starting to go down hill but available for 100 each. Not a bad tool for its purpose. I cant see the use for a small stapler running off anything but air.

I have a 5 horse/13 gallon oil-less compressor that I used when I had my own shop. I didn't find it significantly quieter than the oiled units the same size I used before and since---but it has been more maintenance. I used to have to put a rebuild kit in every 2-3 years because of the heat it created with just me using it.If I'd have ever taken on staff it would have needed it more often.

I find the two most important things you can do are; get your air lines and hoses up on the ceiling and drop down beside your work area to avoid the tangle and isolate the compressor to reduce the noise. You have to ensure adequate air flow to cool it , but any little bit helps. The shop I spent my first 5 years in had a compressor that sounded like a rock crusher out in the open but we had it an enclosed stairwell with a louvered door for ventilation and it was not loud enough to make you raise your voice when it was running.

Agree totally making some kind of sound absorbing curtain, wall or what hav ya, great point Darren. In that, if not avail room I would recommend having the compressor in the same temperature as shop air lines if at all possible, just eliminates some condensation. And my present problem, both issues and I have lived with this problem in many shops ( but quiet is the key ).

The newer compressors may be different, I had a lil CH brand in the early eighties and it worked great at home as a part time hobby n wrenching, wood working enthusiast thru three homes n family. I could pull it around handily it was like 2' long 2' tall
It was noisy as all get out and I had a quick connect to a larger old lp tank in a garage for better supply as some tool usage you had to wait or short order process, a pita.
For a person use to using 5hp compressors plus at work shops and a custom built 16hp running a twin cyl compressor on my service truck. The lil Cambell Hausfeld in the back garage did a noisy darn good job, complete rebuilds repaints w/86jeep, 71chev trk, 67 RS plus all the hobby jobs to help raise a family.

I can now run a hose pretty quick with a 12cfm n 5hp oil type in the garage if when I would get consistent need of air. So considered another dual purpose compressor myself. It was going to be very short, oil type probably, with wheels and have ability to lift pretty easy. But as I read the HF reviews they are all noisy! go figure. I guess set it on a rubber mud flap at least.

I do believe I have hijacked this thread. It was not my intention.

As I mentioned I had a senco little 1 gal, great for a little quick work when you don't want to fill a big tank. Thing is absolutely the quietest compressor I've ever had, but had problems with the kill switch. Tried to fix it myself and still did the same thing. Unfortunately many people have had this problem.
Point being though is that they can and do make oil-less that are quiet. (and dependable)

Yes and I am *#@$! mad about that!
No, quite the contrary, it's gotten a heck of a lot more interest than when it was just about my sick staple gun.
BTW, it quit again, but now I know I need to get that O ring replaced.

FWIW Rich, I use a Bostitch gun. I wish they made a long nose because I really like it. Great tool. Never had a single problem with it.
Title: Re: Problem with staple gun
Post by: Rich on January 06, 2017, 04:25:12 am
I think Bostitch is a good name, been around a long time anyway. The EZ Fasten gun I have? I don't know much about it, but it seems to be made well and I hate to throw anything out if it can still be made to work with not too much effort and expense.

Have you tried a little Vaseline etc... on the old O ring(S) ? It softens the rubber and swells them a little to get a better seal. Might buy you some time while you're sourcing new ones.
