Hi. I'm going to be installing some 3/4" poplar trim on 3/4" wood
backing and need some advice. I have both 16 and 18 gauge nailers.
Because of the style of the trim, I'm going to have to nail pretty
close to the edges, so I figure the 18 gauge is the best choice. We
got the trim custom made and the wife will kill me if I split it.
I have a 2 part question. First, if I go with the 18 gauge, would the
3/4" poplar just create a bunch of 18 gauge pretzels and second, since
the brads are only 1.25", is 1/2" penetration into the backing enough?
I guess the other question would be, if I go with the 16 gauge, is it
likely to split the wood?
There are some areas of this trim where I have plenty of room (at the
top and bottom of these 4 ft pieces) and areas where I have to be
closer to the edge. I think I'm going to use the long 16 gauge in
those roomy areas and use the 18 in the tight spaces just for some
Thanks all for your help.
Poplar is pretty soft, use some glue and you'll be fine.
The smaller (diameter) fastener the better if you're concerned about
Another thing to consider is that most pneumatic fasteners have a
chisel point (not round). IMHO, you want to turn the gun so that the
chisel point cuts through the grain instead of spreading the grain as
it goes in. In thin stock I'll turn the gun so that the chisel point
is perpendicular to the direction of the grain. This is a lesson
learned from hanging miles of casing and applies to both pins and
finish nails. YMMV
All else being equal, the higher the gauge the less likely you are to split
your trim. However, if your trim is expensive/rare/in limited supply, why
take the chance ... when close to an end, pre-drill and use small finishing
BTW, this is a perfect opportunity to add to your tool arsenal and buy a
good 21ga pin nailer. ;)
Mine does, mine does, mine does. LOL... I have the Grex and it came with
an assortment of every size pin that it will shoot in quantities of 1000
each. The gun has performed flawlessly and is fun to use. I think I have
used and almost run out of 6 or 7 of the sizes. It shoots up to 1-3/8" and
down to 3/8. It has no problem making a long pin disappear in hard wood but
as you might suspect it can come out unexpectedly in weird grain. I never
thought I would use it as much as I do.
If it weren't for the Toyota badging (not to mention the word
"TOYOTA in the window) I would have guessed it to be the redesign of the
Dave in Houston
Nothing new under sun, I guess.
Here's some samples of the high-beltline designs from Chrysler. 73
years ago! Not so much the nose as the side view.
And where did today's Malibu's nose come from? (btw, that's a 2001 S4
Even more pronounced is the fact that the newer Audis are being ripped
Hell, even Nissan stole the TT outright. Bastards.
Don't get me started.
Just to follow up, did it yesterday. 16 gauge where I had plenty of
room, and 18 in the tight spots just for reinforcement. Worked
Even got my crown about 90% done yesterday. A real accomplishment when
you consider my house has angles that Dr Suess would be proud of.
Thanks again for the help. Now I just need to make a decent case for
the pin nailer...
