Stack cutting?

If you choose brads, just make sure they don't protrude from either side.

very good suggestion. rocking work sucks.

i usually run the back across my belt sander real quick to knock em down if they protrude out the back

i am told luan is used as a veneer on cabinets. none of the big box stores around me have it. just a local lumber yard. they even quarter the sheets for me so i can cut it the rest of the way down in my 10x10 shop. it is a very soft wood venerable  to tear out so i always stack one more than i need. 

Lauan plywood was commonly used as an underlayment for flooring, especially sheet flooring.  I don't know if it's as common these days.  Seems like flooring manufacturers have figured out that they make more $$ if they specify their own proprietary underlayment. 

Anyway, Lauan is the common name for a wood called Meranti that grows in S.E. Asia.  Most of the varieties are pretty soft, even though Meranti is a hardwood.

Lauan ply was also commonly used as door skins for builder grade, hollow core, interior doors.  It's relatively stable, but a little coarser grain than something like Baltic Birch.  It is useable for scrolled projects, but I think BB ply is higher quality and typically a better choice for most woodworking/scrolling applications.

your question could be answered in several ways. I'm not the first to post, but the first thing is how many do ya plan on cuttin' at once? I started out usin' double back tape, & then went to my hot glue gun. 

Second thing is what do ya plan on usin' for a blade? Remember, the more ya cut, the bigger blade you'll need. On the other hand, you'll have to watch your speed because Luan chips & will leave rough edges if ya try to run to fast. Sometimes it'll break, depending on the pattern. Were I you, I'd start out with a couple, or three in your stack, use a #3 or #4 blade,  & see how it works out for ya. Dependin' on yer pattern, cut your inside cuts first, then cut yer outside pattern. 

If ya do decide to use the hot glue gun, glue on the outside of your complete stack. Don't glue between layers! jm .02 worth.

something else to keep in mind when you're shoppin' for Luan. There is an 1/8" underlayment available, too. Personally, the under layment would be better for ya than Luan. It'd be stronger, less chippin', & smoother cuts. And it would be alot easier on blades, too. Priced out about the same, as well.

Brian,when I stack cut, I like to use the hot glue gun. I will cut as many  as six layers of 1/8" stock, per stack. I usually clamp the stack together with spring clamps, then run a bead of glue around the outer edge of the stack. I run the bead in a sqiggly motion,gluing from the top of the stack to the bottom.

when using luan i tape most cuts into place with painters tape as i go along. this cuts way down on vibration and stress small frets. i also slip my fingers or a strip of luan under the cut before removing from the blade from a fresh cut and blue tape the back as well.

I haven't tried it yet. I plan on stack cutting luan 1/8 inch ply. What is the method of choice to hold together. My thoughts are hot glue but I figure better to ask. Thx in advance for any help.

I pin nail them together with the Ryobe finish nailer $99.00 what a deal.Plus it comes in real handy for frames  or just quick mounting names on a stand !
