I know that this is not the place for this but it's the place I think I could get an answer.
I got a used Grex P635 23 gauge pin nailer and it is working properly using 3/4 inch pins but when I use a 1 1/4 pin it jams, it's supposed to take up to 1 3/8 inch pins.
Could anyone tell me what could be wrong.
Thanks Stuart
P.S I'm coming to the end of the reno of my kitchen cabinets I,m working on the moldings will put up photos.

all i can think of is that the 23 gauge pin nails that are 1-1/4" long are of a brand that don't work with your nailer.
agreed...

i have the Grex 650 shots up to 2” I only have used Grex pins
home depot for one sales them I do not believe they have a 1”1/4 pin
they are small and hard to see but one end is Chiseled and Has to be placed in a downward position
also you need to pay attention to air pressure longer pins harder wood more. more pressure
I’ve never had my Grex jam
lucky I guess
Anyone that has not used a 23 gauge pinner needs to realize that the little pins will follow the grain I’ve had them go in and make U turn also follow grain and come out the side

I checked out the Grex site and when I was checking it out the info said they could take up to 1 1/4 inch pins.
Thanks Semipro I went to their site under products where they said that 1 1/4 was excluded
Thanks

1”1/4

That seems really odd. I'd love to hear the explanation for why not that size.
Chuck
just guessing but the 1”3/8 close enough
I really like the pinner but the pins are are hard to store. mine holds 9 different sizes
I can put 2000 pins of each size in a box 2”” square

Pusserboy, I ran into jamming problems with a floor nailer once that turned out to be that the nails (which are glued into a stick) were not at a right angle... causing the striker in the nailer to miss the head. To check the nails, you can take 2 sticks if nails and butt them end to end against each other... then rotate 1 stick to compare again. They should butt tight if square. If they have a lean to them, make sure they are loaded into the gun so the head of the nail leans toward the striker.

I was told at the time that sometimes the nails sit in a hot railroad car and the glue that holds the nails in a stick can distort causing this problem. Also make sure the striker is smooth (not chipped). It is more likely a nail problem since the shorter nails work fine.

Generally when using a pin nailer to shoot into the edge of a board... the u turn problem is almost eliminated when holding the nailer at a right angle to the edge of the board. The deflection is caused by the chisel end if the nail...where one edge of the chisel encounters the edge of hard grain, causing it to ricochet. By shooting with the gun at a right angle to the edge... it allows the nail to bow into the length of the board instead of out the side. Also remain diligent of where your fingers are so the nail doesn't exit into your fingers.

Hi Stuart,

I also am curious as to why not 1-1/4'' ? but as you stated and I was about to recommend, the 1-3/8''will more than likely do the job. Depending on the application I can also use my 18 gauge nailer. The first I bought was a 16 gauga that I rarely use now that I have the other two and also a framing nailer. Such nice tools to use when you don't need to hold such small pins/nails and you don't have to pound in long nails when doing construction.

Well there is no reason why, but the Grex will not handle 1 1/4 " pin nails but today I bought 1 3/8 " and just tried them and the result is--------------------------------------------- They work perfectly which makes me very happy because on Amazon.ca the gun costs with shipping and tax comes to $292 I got mine from a pon shop for $25 ( MERRY CHRISTMAS )
Thanks for the info.

you should have no complaints with that price one heck of a deal
i usually stick with the brand nails that go with the tool, I used some off brand nails in a 18 gauge Senco when I had it repair they told me that some of makers use different type glues to hold them together causing trouble in the plunger
, i hade to replace everything in the nose

That is strange but that's good news and that is an amazing price for a working Grex.

Pin nailers make certain operations much easier. I use them to posiiton face frames for example and often they hold picture frames tight while glue sets. I have an off brand and it has worked perfectly for a long time. Read the instructions for cleaning and lubrication instructions.
