Re: 1/4 inch vs. 6mm Hardiflex

What is holding the board if the rivet's head is sanded off? I'm just wondering. I have no idea because I haven't used rivets for this purpose.

What installers usually do is to drill a hole while sumultaneously countersinking the board. The rivet should rest on the countersunk hole. In the event that a portion of the rivet is not flush with the surface, that is when they sand off part of the head. HTH!

Re: 1/4 inch vs. 6mm Hardiflex

Ah! Is there a special drill bit for countersinking it? Or do they just use the tip of the chuck?

I believe they only use the tip of the chuck.....I'll have to double check!!

there are lots of countersinks available locally. the drill chuck is not designed for countersinking (unfortunately pinoys who know less tends to do things they feel easier, like using a ratchet or a pair of pliers as a hammer). It is always better to teach and preach the correct process or method, let us try hard NOT to share wrong practices which others tend to learn and believe to be correct.

I did not say yes to the question did I? as I have said I am not sure......If you check all my posts If I am not sure I will say I am not sure or "I think"........I am not a "know it all"......I am just a Contractor/Civil Engineer/Real Estate Broker with 16 years of experience. In all my comments I always put HTH!, meaning hope this helps, if you think it wont help then don't apply......simple as that!! I know for a fact that there are countersinking tools in the market, but realistically construction workers have their strange ways of doing things unconventionally. Do I agree with their methods? sometimes I do, sometimes I do not......It all depends which works and which does not........ And going back to the question and after checking with my installer.....yes they use a modified chuck with an attachment of some sort that simultaneously countersunk the boards. Purists may not agree with their methods but hey, it works!! Let it also be known that what we share in this forum are just opinions and suggestions, we are not forcing anybody to believe in what we share. What works for some may not work for others. Now, if there is a new policy about only sharing "by-the-book" methods then so be it.

I am not saying anything about you... in fact I am commenting on what you said, do not take it as an attack on you because it is not. I have met people in the woodworking industry that uses a plank of wood instead of an existing fence on the tablesaw, 20 years doesn't mean what they do is correct too. I am stating that yes you can use what you want to, but it is best to give a correct advice. there are people here that know zip about the craft, it would be proper to share what is correct instead of what is pwede na. it is what keeps people from improving and not moving backwards. Don't you think so?
If I knew nothing about the craft and I read that you can use the drill chuck to drill a countersink, what stops me from doing so? do you think that is instilling good information?
Now what if someone posted that a circular saw mounted under the table is a very good replacement of a ts?
I am not stopping you from posting what you want. it is a reflection of what you know and how you do things.

btw, I have been woodworking for 3 years, two of which I did not do much...

do not take it bad, it is a reminder not a warning or an insult.

Re: 1/4 inch vs. 6mm Hardiflex

haha, akala ko $60 yung set of 3 bits, $60 each pala yon 😮

Re: 1/4 inch vs. 6mm Hardiflex

What is this countersinking pala? Do I need these bits when my carpenter is ready to start painting the hardiflex na? I have him use the hardiscrew now instead of the rivet.

btw, I ordered the 6mm from a James Hardie Hardiflex dealer and my carpenter was amazed kasi mas makapal daw sa 1/4 na sanay na nyang gamitin. I told him, wala din asbestos ito hehe!

All thanks to you guys for helping me distinguish between the 2! 🙂

Re: 1/4 inch vs. 6mm Hardiflex

A countersink is a conical hole cut into a manufactured object, or the cutter used to cut such a hole. A common usage is to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material.

hmm... so this is used for finishing to prepare for paint? So I need this cos I will have him use hardiscrew for my wall?

Re: 1/4 inch vs. 6mm Hardiflex

You need this before screwing in the Hardiflex. It is use to make a recessed on the screw hole so the screrw head will not protrude, making finishing easier.

Correct me if I'm wrong, so he needs to countersink the hardiflex first before screwing it through the metal stud/track with the hardiscrew?

Maybe I need to ask show this to him, cos he will also paint the hardiflex wall.

Re: 1/4 inch vs. 6mm Hardiflex

Yes, you got it right.

That is price for a set of 3.

An alternative would be Wolfcraft 2590, set of 4, about $25. Or other styles like these (hand, adjustable, one size fits all, etc.).

I don't know whether or what countersinks are available locally.

In absence of 'proper' countersink, I suppose you could use a larger (twist) drill bit mounted on a second drill/driver or hand drill. Tedious to be switching drills, but if there are two people...

Another option, unconventional, could be to use pan head screws, so the screw heads are exposed instead of hidden. This gives the 'battleship' or 'removable panel' look, especially if the screw heads are unpainted and stainless steel (e.g., paint panels before mounting).
