About to begin building my kit far away from my home base and shop. Compressed air is not an option here and the notion of popping all those rivets by hand is not appealing.

There are a number of electric pop rivet drill/guns available but I noted that Zenith modifies the tips on the manual and pneumatic tools they offer.

I did not find a battery operated tool offered by Zenith and wanted to ask the Zenith Builder's group if anyone has successfully modified the tip that comes with the battery operated gun to work as Zenith intended? If yes, which gun and what steps did you take to accomplish the task?

         Interesting! I definitely machined a deeper dome. 
That really make me want to get one direct from zenith to make sure that I’ve machined mine to a good shape!

I attempted it twice and an the second attempt, I only just hit the cavity. I’ll post a photo of my “good” nose pieces tonight.

I wonder if mine are too deep?

Zenith sell the nose pieces that fit the Milwaukee, I think it is the same ones that fit the air gun.

Hello David, this Astro blind rivet adapter works well using The Zenith rivet nose tips. Hope this helps.

After pulling a rivet, do you have to manually reverse the drill to release the mandrel/stem from the jaws?

With the Milwaukee, when you release the trigger, it automatically reverses to release the mandrel/stem.


Yes Sir, you are correct but it really is not much effort to release the mandrel. It seems to do a good job.

Mike, the Grapow gun listed above from Amazon is a full cycle gun that pulls, pops and then resets automatically. Dropping the stem. No need to reverse the gun. Seems a good value for $149. 

The Girapow Cordless rivet gun is available at an attractive price point.  It seems like a good deal; but, there are a couple things I took into consideration:

  1. The Girapow brand is not familiar to me.  I am not being critical of the tool...I just prefer tools from a company that has an established reputation.
  2. The length from the tip of the nose piece to the back end of the motor housing is significantly longer than that of the Milwaukee tool...or most of the pneumatic rivet pullers.  That is especially true if you remove the stem catcher from the Milwaukee rivet gun.  Note:  This consideration applies to the Astro (and similar) adapters that are used on cordless drills.  There are some places where that extra length will make it more difficult to pull the rivets.

I hope the Girapow tool is a great success and that we get to hear more about it as the Zenith builders put them to the test.
