Thank you Amazon for making building scary black rifles easy.
Next I will add a #ShoulderThingThatGoesUp.
Some of them even have the shoulder thing that goes up!
What's happening inside (see photos): As you compress the tool against a surface, the firing pin pushes against the hammer until the end of the compression stroke. The firing pin is held crooked in its spring and it will not straighten until the top of the compression stroke at which point it aligns with the hole in the hammer. When it aligns, the hammer is allowed to fall against the thicker section of the firing pin and this drives the point into your work surface.
What can go wrong: If the firing pin and hammer align prematurely, the firing pin slides into the hammer before it can develop any spring tension behind the hammer and you will get either a very light strike or maybe no sensation of a strike at all. If the firing pin catches on the rim of the hammer and never aligns, then you will get all the compression necessary for a good strike, but the hammer will not fall and no strike will occur.
How to fix it: There are videos available that show how to repair this tool when it malfunctions, but what you'll need to do is remove the front tube from the middle tube and pull out the firing pin and spring. Make sure the firing pin is NOT straight in the spring; it needs to be forced to one side so it can press against the rim of the hammer. If necessary, remove the spring from the firing pin and bend the spring it so the firing pin is forced to one side of the spring (also in photos).
I also found that the contact faces of the firing pin and hammer can be lightly polished so they slide more easily against each other, but this is tricky—if you polish them too much or even slightly chamfer the edges, the firing pin may slide too easily off the face of the hammer and you'll get consistently light strikes.
After doing all of this, mine works ... most of the time. I still get occasional light strikes or no strikes and when it starts acting up I need to take apart the tool and spin one or more parts to get new alignment.
Three stars for being less than $4.
Michigan Industrial Tools contacted me the day after my 1-star review and offered to send me a new one after verifying my purchase with a photo. The new punch looks the same on the outside, but the spring and hammer pieces look slightly different. One huge improvement is that the new punch works! So I am upgrading the review to 5 stars. If I was the seller, I would stop shipping the old malfunctioning ones, since that would only tarnish the seller's reputation. BTW both the new and old version were made in China.
Old Review: I was able to mark about 4 holes in wood (by hand!) before it started failing. Less than 60 seconds of working time. The reviews say the manufacture has a lifetime warranty and there was a bad batch that was sold. It seems I received a bad one. If the manufacturer can provide me with a working replacement I will update the score accordingly.
Tip is sharp and has remained sharp for over 200 cycles in mild steel.
All metal construction.
Does not always "click"
Springs too weak to indent steel well.
When I do manage to make it work, it is so weak it's useless. It barely leaves a mark on aluminum. Even after multiple strikes, I still had to get out my old punch and hammer to finish the job.
I can't recommend this product. It will do nothing but waste your time. If I hadn't foolishly thrown away the packaging, I'd return it.
Top international reviews
-it was cheap
- need to tighten together after a few uses
- weaker than any other automatic punch
- brass probably has lead in it
- dulled tip after 100 uses
- sometimes misses a hit
Would not recommend for any professional not even an arts and crafts class should use this thing.
Tested quickly on a file and it is indeed hardened at the tip, as the file just skated across the tip portion.
Quite pleased for the price. Will purchase another.
Thank from a journey man..
