Pneumatic stapler driving too deep

[vavet]

I’m using a harbor freight 68019 narrow crown pneumatic stapler to fasten insulation fabric to my walls. I’m using 5/8” staples with the air turned down to about to 50 psi to prevent overdriving. I have problems with jamming and no feeding. I’ve oiled the stapler, so I don’t think that’s the issue.

If I was to use longer staples, would that allow me to use higher air pressure without overdriving? In my mind, that should work but I don’t have much experience with these air staplers.

the jam is likely due to too low air pressure
is there an adjustment on th nose of the stapler? thats how you adjust the drive depth.
a narrow crown pneumatic stapler isn't really the ideal tool to fasten fabric etc

I have several of the hf staplers ,brad nailers. 50 psi is too low. no depth adjustment on these units. try 70 psi. depends on your wall material. I found I have to adjust air pressure based on the material .

I’d just try the longer ones at the higher PSI and be happy. It’s those bells and whistles you are missing with the HF guns so you just need to find a way to compensate which is often pretty easy. Overall I’ve found HF air tools to be pretty darned reliable and durable. I have several and find that if they work good right out of the box they are fine. If not just take them right back. Not much quality control in China.......or here either anymore!

Yep, wrong tool as those are designed to drive deeply for woodworking and no adjustment at least on mine

Low pressure is the jam cause.

What I've done on the one I use for similar jobs, I have three, is shorten the driver pin. Easiest way to do that is pull the trigger and hold it. As long as the trigger is held, when connected to air of course, the pin will stay extended. Now hold it to a grinding wheel and eyeball the amount you want off.

Wouldn't want do this to my Sencos, but for a 25 buck stapler it's a good fix.

Hey KenC
Great idea. I had to take the cartridge off to be able to do it, but I followed your advice and filed down the driver pin. I tried longer staples before I did that, and it wasn’t as bad, but it was still deeper than I would’ve liked at a reasonable air pressure. So then I disassembled and filed down about 1/8”. I tried that with the short staples again at about 80 psi....too deep, but it was just right with the 1-1/4” staples.


thanks for the input
