He was asking how to nail bamboo.

That was the original post.

Never mentioned construction until it was brought up... and that would be me.

Stephen: Define Cross Grain and Horizontal...
what is "Cross grain"
what is "Horizontal"
Tell us how a cross grain can be horizontal bamboo construction.

Your getting your posters confused.

I mentioned cross grain,(when you were confused about what the product was), and I was referring to the engineered construction. The post does say "construction".

Read slowly.

Why Ray why? You pullin out the ole manual out on me here... or is it your in need of another answer to pass a test and get another patch on your sleeve?

Ya'll guys come here to garner installation techniques you have no clue about and YOU want FREE ANSWERS Ray? When you block your site cus you do not want to share your super secret info? That answer is going to cost you bout $350.00 We don't like sharing with inspectors although, this is a free and open forum

Ahh this is like the ole days on Freds forum ain't it. Remember them days, thats when you guys actually got interested in inspecting hardwood cus Fred was making so much money doing it. Now you all is book read experts. Great...I am sooo impressed.

I was sure you did not know the answers to the questions.

And you obviously don't or you would post the answers just to show me up.

Excuse me for butting in but...I think some of us would be interested to know what legitimate questions are being asked. So far all I've heard is off the wall confusion. For some reason I have the impression your malisiously trying to challenge people without understanding the posts and what their saying,( like skimming through), and attacking people A little tip...On this Forum I have found it's important to read everything and take in what people are saying, try to understand before asking questions. If people dont understand we're more than happy to explain a different way. I just get the impression there's different motives, for some strange reason.

Bamboo is a grass with knuckles?
Wood has knots?
I came to help Ken, not be told how horrible inspectors are. I don't make general comments concerning the installation community and for good reason... We are all in the same industry working at making a living.

Leave the hate and anger someplace else and all will be good.

I read posts stating gaps, planks not straight with cross pull appearance is fine and fill the gaps on an engineered floor with gaps so wide the tongues are visible from a standing position and ya'll think inspectors are horrible?

I answered the questions of the original posts only to be brought into Installer politics......

and that bamboo would not be horizontal/engineered. Stranded bamboo can have knuckles. Horizontal has knuckles and filets.

I don't see filets to indicate the material as horizontal.

That is what I see.

Nice post. I'm sure everyone looks forward to hearing this type of participation. By the way... the obsene post to SP was extra special, I'm sure every professional will keep that on file.

But I must say, I'm still a little confused, why your accusations of hate and anger, while it actually sounds like your pretty hateful and angry for some reason.

I am also confused on your claim in answering the original post, or staying on thread, I'm still looking for that.

Relax, life is too short, have a wonderful evening.

If you don't know your basic bamboo flooring terms and construction. I know of several bamboo glossarys and bamboo flooring/manufacturing glossarys. If you need them just look it up. I have been done playing games with you inspectors. I don't have the time.
I will however continue to warn the public consumer about how the inspection community works. How many lives have been ruined by junk flooring science and inexperienced inspectors.

Trying to help the original poster was of no use.

The problem is obviously excessive air pressure.

Solid oak uses about 80# psi.

Engineered bamboo would need closer to 60#, but test to make sure.

5/8" engineered?

I still would like to know the product.

5/8" thick is usually Stranded or Solid (either vertical or horizontal),

It sounds like you figured out the pressure problem yourself. Play with it until you have the best result.
As far as your other questions I would think 3-4 staples per board would be better.
For staples not set try taking a slot head screwdriver, hold it parallel to the tongue with the narrow flat side touching the staple. Grab your hammer and use the screwdriver as you would a nail set.
1 1/2" staples should be fine. Try spraying WD40 on them before putting them in your nail gun. Might help them penetrate better. Hope this helps

Why would you suggest 3-4 staples per 3' board ?

No special reason other than personal preference. If you're looking for a by the book answer, don't have one. Over the years when I've nailed up floor I always seemed to end up with a nail about every nine inches or so. My buddies told me it was because I'm short. Oh well, I just came here trying to help out someone who sounds like he hasn't laid much floor.

4-5 staples with 3 you only have one on either end and one in the middle, not enough.

15-16 gauge is too big of a staple.
too much beef and will telegraph a bump in the surface.

You need a 3/16 crown 1½" 18-20 gauge staples at 4-6 intervals.

Haven't had that issue with my M111, installing 5/8". I guess my psi is right, and I'm down in the crease. I can see where that could be an issue if there's minimal meat on top of the tongue, or other variables,( that doesnt look like his problem). I'm sure those guns will work...I have the Bostitch 18 Ga, with a 5/8 max. Ofcoarse if we're talking strand, forget it.
