breadstick Posted March 21, 2016 Report Share Posted March 21, 2016 I'm heading to a new sawmill tomorrow and will definitely be getting some new plywood. I've been using 1/4" because it's what I can get closest. I'm at least getting 1/8" for backers, but I thought it'd be easier to stack cut 1/8" three at a time, but is it be too thin to use spirals?

Scrappile Posted March 21, 2016 Report Share Posted March 21, 2016 I use to cut 1/8" stacked 2 or 3 at a time with no problem. I stack cut 2 1/4" pieces often with no problem. I use the 3/0 spiral. Quote Link to comment Share on other sites More sharing options...
john shankel Posted March 21, 2016 Report Share Posted March 21, 2016 yes i see no problem with stack cutting 1/8 Quote Link to comment Share on other sites More sharing options...
redwine Posted March 21, 2016 Report Share Posted March 21, 2016 (edited) No, 1/8" ply is not to thin for spirals when stack cutting 2 or more at a time. Now this is using Baltic Birch ply. You want to make sure that the ply you are going to purchase is at least cabinet grade and with little or no voids. Does the sawmill have different types of ply such as oak, cherry, poplar, etc? Some times oak will splinter at the wrong place of the cut and stick out like a sore thumb! Erv . Edited March 21, 2016 by redwine Quote Link to comment Share on other sites More sharing options...

WayneMahler Posted March 21, 2016 Report Share Posted March 21, 2016 Stack cutting 1/8" ply I go up to 5 layers. Using a 3/0 spiral I would stay 2 or 3 layers. Quote Link to comment Share on other sites More sharing options...
Lucky2 Posted March 22, 2016 Report Share Posted March 22, 2016 I don't use spiral blades,but, I do stack cut. I use the FDUR blades, and I usually use a #3-#5 blade. Most of the time when I stack-cut, I usually cut five layers of 1/8" of baltic birch. Lenp0 Quote Link to comment Share on other sites More sharing options...
Lucky2 Posted March 22, 2016 Report Share Posted March 22, 2016 Is it a sawmill you will be going to, or is it a plywood mill? There is a difference, sawmills cut lumber and plywood mills make plywood. If it is a plywood mill, are you sure they lay-up 1/8" plywood. The one I worked at didn't, they just couldn't turn the stock thin enough to go through the dryer. Len Quote Link to comment Share on other sites More sharing options...
breadstick Posted March 22, 2016 Author Report Share Posted March 22, 2016 It's a sawmill. Checking it out tomorrow when my sister-in-law goes back home. They only sell hardwood 4/4" an thicker, but they will saw one down for me if I buy one, so I'll essentially get three boards for the price of one (plus the $15 fee saw fee).

daveww1 Posted March 22, 2016 Report Share Posted March 22, 2016 I cut 3 to 4 layers of 1/8" Baltic birch at a time using a 2/0 blade Quote Link to comment Share on other sites More sharing options...
breadstick Posted March 22, 2016 Author Report Share Posted March 22, 2016 Thanks everyone. Gonna try stacking 4 1/8" and use a 0 blade. Quote Link to comment Share on other sites More sharing options...

It sounds to me like you are going to end up with 3 pieces of hardwood 1/8" thick by the sawmill re-sawing 4/4" boards. Are they going to cut the pieces over size an then plane down to 1/8" or are they going to end up rough sawn? To end up with 3 pieces that can be planed to 1/8" out of a 4/4" board they would have to be using a band saw mill.

breadstick Posted March 22, 2016 Author Report Share Posted March 22, 2016 I don't think I'm explaining it right. I'm buying regular 1/8" plywood from them. I'm also going to buy probably 5/4 hardwood from them and have them sawmill bandsaw it into three pieces about 3/8" each. I don't know how rough they'll be, but I have a planer so I can get them smoother if need be. Quote Link to comment Share on other sites More sharing options...
stoney Posted March 22, 2016 Report Share Posted March 22, 2016 (edited) Ok now we are getting some place. You are buying plywood and hardwood boards. I'm glad we got that cleared up. I sometimes resaw boards up to 6" wide on my tablesaw and then run them through my planer to the desired thickness.

Sparkey Posted March 22, 2016 Report Share Posted March 22, 2016 I stack cut three 1/4" pieces of birch plywood using a 3/0 spiral blade. If I was cutting 1/8" birch plywood I would stack 4 or 5. Quote Link to comment Share on other sites More sharing options...
