Bob,

  

 I have purchased the gun from Zenith and have never had any problems with it. Expensive?....yes but I wanted to make sure I had the right force when pulling rivets.

  

 I have recently purchased a blue colored pneumatic inexpensive rivet gun from Harbor Freight tools that works as good if not better than the big yellow Zenith gun! I have purchased two of them which were recommend from another aircraft building site. I also made the heads similar to the rivet heads from Zenith and switch gun regularly between different size rivets. I have had no problems with these guns and they are a few years old already.

When I first started looking for a rivet puller, I shied away from the gun that

was being offered by Zenith because I had heard from builders on this List, that

there was many instances of cracking in the casings. As a replacement I decided

to go with a gun that was being offered by ACS ( see pic below ) however it is

starting to look like this was not my best decision. 



I had difficulty with the setup instructions ( Chinese instructions ) and for

the life of me I still have not been able to get the oil level correct. The

instructions state that the unit should be filled with oil up to the top of the

frame, without showing where exactly what they consider as being the top or the

exact filling level is. 



My second mistake was purchasing two guns so as not to have to continually swap

out the two tips. As it stands, when I do get one of the (at)#$%&* things to

work, it won't pull more then a dozen or so rivets, before me being obliged

to open up the air cylinder and start fidgeting with the oil level again. 



I am basically a neat person, and I can't live with the constant spewing of

oil out the front, or the back stem catcher, and ending up on my freshly made

parts, or my work table for that matter. I am now in the process of trying to

look for a replacement, but all the suppliers seem to have the same low cost

gun. The list of resellers I checked with is rather extensive and includes, but

is not limited to, The Yard, ATS, Browns, Cleavland, US Tools, all registered

trademarks etc, and a few more I will not mention. 



My question to the List is this, is the rivet gun being sold by all of these

suppliers the same gun. I have looked as best as I can, and every last one is

showing what looks to be the exact same unit on their web-page, with the only

difference being the color or the pricing. The cases are identical, the same

tips, the same nose pieces, hell they even the same triggering mechanism, and

the only difference so far is prices, that are anywhere between 40$, to a 140$. 



For those of you who have used any of the above guns, are you aware of any

difference in quality of these guns, or is it a " find the peanut under the

shell " type of situation for me to get a proper replacement that will

work, 



Thank's to all of you who will take the time to respond to my concerns.

I got whatever gun came with the Zenith tool kit.  It requires no oil  

and has been trouble free through about 3,000 rivets.  Are you sure  

they're all the same?

A big thank you to all who responded to my call for help. 



Yesterday evening I was able to find, and correct the problem with my rivet gun.  As was mentioned in a previous response, the defect was with the large O-ring on the piston at the top of the handle.  it has an O-ring at the rear to seal the oil, and both guns had O-rings that were dried out and hardened.



This is why the gun was quitting after a dozen or so rivets, because the oil was leaking pass the O-ring into the stem catcher.  Now it is working great, with no oil leaks.



There was however one casualty in all this and that is my second gun.  While I was rebuilding the first one on the bench I casually pulled the trigger to check how far back the piston was pulling, and when it evacuated the air from the lower canister, it blow the spring from my second gun off the bench, and was never to be seen again.
