Spruce wood for cabinet??

[mayhem13]

FWIW, I had to replace a section of countertop in my kitchen last year, so I took my wife to the local hardwood store to look at the bamboo countertop slabs they had in stock. They happily opened up a bunch of them, and every single one had checking and splitting that made them unusable. I'm not sold on the long term stability of those bamboo products. With the price of Baltic Birch going through the roof, I don't know what I'd use for a box anymore.

That's true...while the Bamboo used might be the same, the glue used and the process of laminating the materials may be very different......i should have really made it clear that my board.....wherever it came from was done properly...likely using phenolics and high pressure and dry/stable substrate

It sits out side all year and gets the hose and a scrub brush for cleaning.....it's occasionally passed through the dishwasher too. Folks rave about the Cali Bamboo brand.........just sayin......mine came from Ikea! lol

I didn't see it mentioned, but what type/size of speakers are you building? The inclusion of a ply variety is mainly for stability vs a full spruce.

If you know how to work with solid wood it should work fine.

It is a softwood, but that, from my experience, is not an issue. These are Douglas Fir (a pine, Spruce & Doug Fir [a pine] are interchangeable (in the construction business anyway).

Mmm, good Douglas fir is quite different from spruce. For I'd use for cabinets, spruce I would not.

Where can I get Marine Grade 1 and 1/18th MAHOGANY plywood?

 

[seventenths]

Hong Kong right? There's a rich history of yacht building there... your ply should be available

 

[seventenths]

Adding: Industry suppliers are often found in close proximity to those they serve. I'd first look for lumber/panel goods providers near any large, established boat yards.

Why ask here, at a mainly US, Europe, Canada, Australia, etc. based international Forum, thousands of kilometers/miles away from Hong Kong?

Supposing we suggest some favorite suppliers... do you intend to have plywood planks delivered by FedEx, DHL, UPS, etc?.

Doesn't it make way more sense (or any sense at all) to shop locally?
Aren't you the person most apt to find some local wood supplier?

This whole thread (and similar ones about bamboo "plywood" 🙄, etc.) makes no sense at all.

Tru shipping charge is an issue
BTW, what is marine grade 1? What is 1/18th?

 

[turk 182]

an 1/8th is 3.175 mm

3.175mm is very thin

Dave, I think Juan read the thread title and might not realize the thread starter is the one who veered us off course when we suggested Spruce is not the right choice.

See below

1 and 1/18th MAHOGANY plywood?

One and one/eighteenth inches.
Nice thick stuff.

These are Douglas Fir (a pine, Spruce & Doug Fir [a pine] are interchangeable (in the construction business anyway).

S-P-F designation In certain applications is interchangeable, but not all. For example finger joint studs, yes. Floor joists no.
Pine is too knotty and tough to grade accurately.
Spruce, while surprisingly strong, is too bouncy.
Hemlock and Fir are the choices. Hem-Fir is a designation for just that.
S-P-F will be mostly Pine and Spruce
Hem-Fir will be mostly Hemlock
At least around here.
Where's our resident forester SCD when you need him?

Now I see where the trouble lies. You accidentally separated those two.

 

[seventenths]

Marine ply above 3/4" - 18mm is available but not as common. Panels can be glued to produce thicker sheets but requires some thought regarding clamping. Vacuum bagging would be my preference. Plenty of panels have been glued up with nothing more than weights set on top but a metric ton placed on a 4'x4' glue up yields less than a pound per square inch of pressure. Thin, well spread glue is a must as a puddle in the middle of the panel will not spread evenly and ooze out. I know this from experience.
@Cal Weldon good quality DF is my hands down favorite for framing. Helped frame a 2 story shop with true 2x4/6/8, air dried, old growth (boat wood) lumber milled on site. All hand spiked due to the increased dimensions. Beautiful...

 

[Cal Weldon]

If there was a way of pressurizing the panel from the center out, no problem with ponding liquid adhesive. Alas, I am not aware of one. Great if you had a convex press go over it first to do the bleed out, then onto the flat press. Who knows?

 

[seventenths]

I think the key is laying a nice thin, even glue layer and then using cauls and clamps, tightening from the center outward if you don't have vacuum. I never had a panel fail but became aware of the problem when the panel wasn't flat.. I had used 640lbs on a ~ 40"x 36" and thought it was PLENTY

Douglas Fir is a pine tree.

Douglas fir (Pseudotsuga menziesii)[3] is an evergreen conifer species in the pine family, Pinaceae.
