Materials Question

[oldhudson]

I thought I'd make some bookmarks and wondered if anyone could recommend a source for 1/32" BB plywood.  TIA

[OCtoolguy]

There is a place here near me that has it. I'll have to the name.

[Scrappile]

The only place I could get that locally is a hobby store where the sell model airplanes/trains and such.  Online Amazon, of coarse.

[OCtoolguy]

Here ya go. Great place to deal with.

The owner is very involved with the orange county woodworkers and he is a Vet with a nice museum on site.

Lot of hobby stores, hardware and home improvement stores have a hobby wood selection. Generally I would stay away from it. The main hobby wood sold is very light weight, very carve able and perfect for light planes, boats. Its balsa wood, which is so light, it would snap looking at it. I think most the folks are going to recommend a supplier of hardwood. 1/32 is really thin. That thickness, could probably be kicked up a little. I'm a constant book reader and have a variety of bookmarks. i know they are a bit thicker and haven't worried about breaking them. Just a thought, maybe your project requires that thickness. RJF

I used 1/16 for book marks bought in hobby lobby  or Michaels 

[kmmcrafts]

Back in the day when I made bookmarks I used this ebay seller for my real thin woods.. Always got nice wood what little of it I did purchase from them.. Still have a big box of it that i never did use..

I have a local place where I can get the real thin plywood not sure exactly what it's called.. Finland ply? it's like 1/32 or so thick in 60 x 60 inch sheets just like the BBply.. I've never had a use for it myself..

I have made bookmarks from 1/16th, but even ply at 1/32nd might be fragile.

The place I posted also has 1/64" BB plywood. My neighbor bought a half sheet there. I couldn't believe when I saw it. I never knew they made plywood that thin.

I made a lot of book marks from 1/32" plywood, stack cutting them a dozen at a time.  I believe I got the plywood from a model airplane site online, maybe on ebay.  The recipients of the book marks liked them a lot.  My wife says the stay in the book better, as they have a portion that holds onto the pages similar to a hair pin.  They are actually quite durable.

Didn't know they made plywood that thin, other then what is called vernier and I'm not sure its defined as plywood. I would expect most would would crack through the grain that thin. RJF

[jollyred]

The plywood I used was 1/32" thick and contained 3 layers of veneer.  Don't ask me how they got it that thin, but it is plywood.  I believe it is birch but don't know for sure.

I converted 1/32 to a decimal and divided by 3 layers then put it back to a fraction. One layer would be   inches thick.

Do they have people with real steady hands and tweezers laminating these?

 

How Thick Is a Human Hair in Inches? Individual strands of hair range in thickness from 1/1500 to 1/500 of an inch in diameter, depending on the properties of the hair in question. Typically, blond hair is thinnest since it usually does not have a middle layer like dark hair does. RJF

Pretty small, right?  When I was still a worker bee I ran a precision saw department.  We cut aluminum tooling plate up to 8" thick x 60.00" x 144.00"  We guaranteed +/- .005 tolerance. I would have to explain to new sales people why those tolerances took so long to cut and why we charged so much for it. I would bring a linear vernier to the meetings, set it at .005 and pass it around the room. Many times they would look at it and accuse me of messing with them. They thought I had locked it at zero. I'd have to tell them to hold it up to the light so they could see the gap.A full plate weighs  6981 lbs. Try playing with that wt by your self and standing inches away while a 28" carbide saw blade is screaming towards it. lol

Koskisen company sells plywood that thin and thinner. I've no idea about price or if there is minimum required. They may not even sell retail.  I was just curious how thin plywood came. Sorry for the tiny file. lol

They must have sandwiched it between 2 pieces of 1/4" plywood for shipping.  LOL

My calculator is different

1/32" = 0 .03125"

Then a third of it is 0 .01041666"

I think the decimal point was off in a previous post.

[JimErn]

so much is now metric in lumber this chart should help some

Comes up decent clicking on it. Its amazing they can cut wood thin, since its a natural material with fibers. RJF

No, she drove over there and bought it. We are only about 10 miles from their place of business. But for those who would have to have it shipped, you might be right. Not sure but you can always call them and ask.

The calculator kept multiplying the decimal by 10 and moving it to a whole number and added the denominator. I asked for a fraction from it, so it gave me that. RJF

For quick charts I got this pocket book years ago and its full of charts and material infor. I pick it up all the time. RJF

By the way, Mythbusters had questions constantly on where they got their information for their project. Adam wrote and said they used this. RJF

I remember stories of how years ago Honduran Mahogany was so expensive and regulated  that people would order things from Honduras and have it shipped in crates made from Mahogany. Eventually people at the docks got wise and swapped out the crates for cheaper lumber. Not sure if true but wouldn't be surprised. People can be creative if not totally honest.
