Topic tags/keywords: pin nailer

Coming out of the box it is a beautiful little gun. I can see it’s well made. I’ve always bought the affordable guns, but for a pin nailer that shots 2 inch pins…Wow I’m willing to go the extra $250.00. When I first used Senco a pin nailer I just loved it. They save time and bring up the quality of a job. I had high hopes. I got to tell you I’m real disappointed. It doesn’t quite set the pin, even at 100lbs air pressure. Nailing a 3/4 inch Oak board onto a particle board edge the pins curled up under the Oak. It looks like they penetrated, but pulling the board off I can see them curled under the face of the board. The Grex P650L might work nailing pine to pine, but it sure has its limits for general woodworking. I read a review stating how wonderful this gun was…just goes to show you can’t believe every thing you read.

there are always those hidden factors behind reviews.
Sorry that you are disappointed :(

Apparently, the reviewer was doing something different than you are. What gauge is it? I’ve got an 18 gauge Bostich that has trouble with oak using 1.5 in brads. I’ve found that my 16 gauge Paslode works best, but that’s a lot more than a pin.

Dennis – that’s terrible. I’m sorry to hear it isn’t performing up to expectation. I wondered how a pin that long could stay straight … I guess it can’t! Any chance of the retailer accepting a return from a good customer?

I think I’d return it. I punch 2” 18 gauge brads but have never had a pin nailer. I am told they are the cat’s meow for thin light work like tiny moldings.

The pin nailers use a 22 ga. nail. I shoot 1 inch pins into oak all the time with my PortaCable, no problem. I’m surprised the gun doesn’t work. I almost think I’ve got cheap steal pins, but they are supposed to be Grex pins.

I’ve been using a Cadex on white oak frames and have had no problems. I was also wondering if the pins might be faulty.

My no-name pin nailer will only shoot pins up to 1,” but the gun is rated at 120psi. I’ve shot the pins into oak, and it works fine. Of course, I’m not shooting 2” pins. Is your Grex pinner rated at only 100psi?

SteveRussell has a Grex, and he raves about it. Hopefully, he’ll weigh in on this for you here.

I was contacted by a distributor for Grex. Who claims I should be getting better performance out of this gun. He offered to replace it. This surprised me. Senco never contacted me when I wrote about two of their pin nailers hardened steel bodies cracking in less than a years use. Anyway I’ve contacted the folks who sold it to me to see if they would replace it. If not I’ll send it to Jerry Carter Air tool supply see what he says. If I works the way they say it is supposed to I’ll come back and rave about it.

Deninis , I would be inclined to try some different pins.
Some of the stuff comming out of China( I should say Offshore) is absolute garbage and some of it is “branded”.
I only suggest this to save you a bunch of shipping and running around.

I’ve installed the new driver. Using 110 lbs of air I still get a shiny nail head visible and just flush with the surface. I’m not sold on this product especially at the added cost.

I have the older model Senco micro pinner….the one with no saftey. It was one of the originators of the 23ga market. How they ever got to sell them in this day of saftey regulations, I have no clue. A guy I work with has an Accuset, which is made be Senco. It is older than my Senco. It doesn’t have one either. The point being, originally these things were made to shoot 1” pins max. (micro pin) As new manifacturers get in the game and “improve” things, they lose sight of the original goal. The double trigger saftey is fine, but as the pins get longer, the tiny wire is to hard to control. Even 18ga. brad nails, in longer lengths, have issues with following grain in thicker pieces of wood. Take a 1 7/8” wide x 3/4” thick piece of oak and try to shoot an 18ga brad into the board from the thin side. Shoot exactly in the middle and as straight as possible. It is very unlikely that it makes it out the other side. Even if it does, it will not be centered. It is more likely that it will come out the side somewhere….watch your fingers. A lot of this has to do with the angle of the grain as viewed from the end of the board.
Just my opinion, but 2” is not a micro pin anymore. The original idea was for small mouldings and such. They are just there as clamps, while the glue dries. Being headless, they have very little holding power w/o glue anyway.
