Re: Yet another plywood dilenma (THT)

That is chipboard, also called particle board, not OSB, or Oriented Strand Board. I don't recommend using either for anything, because the dust from both, when cutting, is quite toxic. So practically, it's more of a health concern than structural? I could live with some dust from few cuts for some ...

Re: Yet another plywood dillema (THT)

I kinda guessed that answer (about chipboard). So one more full 8'x4' ply board it is than... If I may ask (just curious), I guess it's because particleboard's (chipboard) inferiority in vertical strength? And/or the overall thickness of it? I've been at several local cabinet makers. Any 12mm (1/2&q...

Re: Yet another plywood dillema (THT)

Thanks. How about using particleboard (chipboard) for some of the braces? I've got quite some leftovers of it, veneered on both sides. Or just bite the bullet and buy third 8'x4' plywood board (and only use up to 1/4 of it)? http://upload.wikimedia.org/wikipedia/commons/thumb/d/d1/Particleboard.jpg/...

Re: Yet another plywood dillema (THT)

Weight will not be of any problem. Workshop is very close to the common room where THT will be located. Even if it ends up really heavy, there are always friends eager to help in return of few beers... :wink: But I'd really like to hear if there are any obvious (or not so much so) pitfalls to using ...

Yet another plywood dilemma (THT)

After a long search for a source of appropriate plywood in my country I'm left with essentially two options. - Wait even more for something to came up. - Use 3/4" (18mm) plywood instead of 1/2" (12mm) to build a THT. I really don't want to wait any more, and the winter is coming... :noob: ...

Re: Bison Pu Max Timber, liquid polyurethane adhesive

It's so reassuring to hear from experienced builder that has already used uncommon adhesives. Thanks mate. And thanks everybody for the help. BTW I've decided to use the Bison Original Montage Kit for my THT build. (Bison PU Max Construct wasn't available locally). I will report about my experience ...

Re: Bison Pu Max Timber, liquid polyurethane adhesive

Is it possible to use/combine traditional glue (only on biscuits and the biscuits holes) and PL (on the whole joint and around the biscuits themselves)?

Re: Bison Pu Max Timber, liquid polyurethane adhesive

Tnx mate, if I can't find PU Max Construct locally than I'll go with Bison (Original) Montage Kit. BTW something I've learned in this thread is that I was wrong to think that every polyurethane based adhesive is also gap filling. When I look at the glue I bought, on Bison Pu Max Timber descriptions ...

Re: Bison Pu Max Timber, liquid polyurethane adhesive

OMG tnx mate, now I'm almost sure I've seen that exact product in local stores. Not sure about that "ORIGINAL" label though. I even think I've been through it's instructions (as with any adhesive I've laid my hands in stores). Yet it says it's a Montage Kit (which I guess still means it's ...

Re: Bison Pu Max Timber, liquid polyurethane adhesive

Expanding 100% polyurethane is an adhesive which achieves its strongest bond through compression ( claps or screws ) and moisture during the curing process. Because it expands, it fills any small gaps so it acts like a gap filler for those situations. So if the adhesive is not 100% polyurethane it ...

Re: Bison Pu Max Timber, liquid polyurethane adhesive

I've contacted Bison's tech support with inquiry about this adhesive's expanding (gap filling) properties. And asked if there is any other adhesive from Bison that meets my requirements better than this particular adhesive. I've also checked http://www.speakerhardware.com. Damn, PL in 10.6oz bottle ...

Re: Bison Pu Max Timber, liquid polyurethane adhesive

That's very kind of you mate, but it's never so simple here. Thing is, if I order something via air shipping (FedEx or UPS), I get to bear ridiculous (and unavoidable) airport custom taxes. If I dear to use ground shipping via postal office, there's big chance I won't get the shipment. Because someo...
