That is true but the Numatx is out of my price range so I make due with what I have.

Thanks for all the responses. So if I understand it correctly, it takes a set amount of force to properly squeeze a specific diameter rivet to get the desired shop head regardless of the rivet length. You set that force by adjusting the air pressure.

I'll be on the lookout for the issues others have brought up too. Based on the generally positive responses, I've just placed the order for it and should get it next week.

Make sure you upgrade to the lighter hose. the standard hose is way too chunky. The lightweight one is a TS Flightlines hose and is superb

It all been said already….. but I love mine and wouldn’t trade it for anything. Probably my favorite tool.

I bought the Numatx tool with the optional hose and all the yokes before starting my -14A build. I love it and almost look forward to repetitive rivet jobs. They are expensive but you can get most of your money back when you sell it later.

I have one of the originals, built by the first Numatx company. Love it. I cant speak for the newer versions, but mine is just fine. I dont use it as much any more--but its still a great tool.

Here is my setup

Hey guys I picked up a Numatx and have been tinkering with it. What is the length of piston travel for you guys? Out of the box there was plenty of air I had to bleed out of the lines and air leaks in a few of the air connectors, but I seem to have sorted all of that out. Piston travel doesn't seem like enough though.

Here's my setup FWIW

The Numatx comes with two rams of different length. The longer one will squeeze most rivets, but when a longer rivet is required, the shorter ram is swapped in for the long one. This allows coverage of the range or rivets typically used. The ram is held in place by an Allen screw at the bottom of the center hole. Just unscrew that, and replace with the other ram when required for proper length.

That’s how mine came, and it covers the gamut.

I'll have to measure the stroke sometime, but what I've done to minimize times I need to change the ram is to buy a couple more flat sets. I've found I need the shorter ram with my dimple dies so for some short rivets I just use a longer flat set to make up the difference of the shorter ram. I think I have three lengths of flat sets right now and that has worked well.
