Quick question.
I am just starting one of Mikes intricate patterns. This pattern http://www.mikesscrollsawpatterns.com/pattern.asp?id=106
This is my 2nd pattern from him and i just got some 1/8" Baltic Birch from Sloans and it seems like almost every piece is somewhat warped, not terrible but not perfectly flat. I stack cut 3 and you can see the middle of the stack a bit raised, and when drilling my entry holes (all 700+ of them) you can hear the drill hit a small gap between the wood. Do you think this will cause any issues when cutting? Anyone experience this? I just want to make sure before I spend 30 hours cutting this beast.

I haven't tried stack cutting yet but it sounds like you didn't have any adhesive in the middle to pull them all together.
Just a thought.

make sure you hold them flat when drilling to avoid splinters on the backs. You can usually hold them flat when cutting but it gets tiresome after awhile. I try to reverse everyother layer of wood before driling or cutting. That helps but still leaves small gaps.
-
I agree with towdude. If you have already stacked and drilled, you will have to hold down on the wood as you cut, which you have to do anyway.
All 1/8" BB will have some cupping to it. So I try to alternate the cupping so when I stack them the stack stays flat.
-
If you have a large piece that is getting cut out in the middle a nail or staple through the spot will help keep all the pieces together. Cut that spot out close to last or you will loose the clamping effect.
-
Don't worry about it. You are going to hold it down to cut it anyway. I do not put adhesive or tape between the layers on something that delicate. It is too hard not to break it when taking it apart.

Hey....I agree with MRSN .... Using a small (tiny thin one) You can by being very carefull and having a plan secure all layers very, very good. Works like a charm. Danny :+}

As you may have noticed I do a few hard patterns. To hold the pieces of 1/8th plywood together (never less that four) I drill holes in the larger waste areas, the last to be cut. In those holes I glue toothpicks, Yep, toothpicks. Drill the holes the size of the toothpicks. dab a touch of glue on the toothpick, sand off the amount sticking out and YOLA, the pieces all stick together and will not move a bit. Use to use brads till I found out about this. Ever hit a nail with a scrollsaw blade.

ninsteat of a nail I sometimes use 2 side carpet tape in between.

Thanks for the toothpick idea.
I use them for lots of things but would not have thought of that.
That would be good for any stack cutting,would all most garrentee no movment

That's why i like these threads. Always find a good idea that would never have thought of.

Toothpicks - wow, never thought of that. Thanks for the great idea.
