CUTTING INCH AND A HALF PLYWOOD IN ONE PASS1/3
I and trying to cut though 2 sheets of 3/4" plywood in one pass. can any one help
Not really advisable if you do not have roller hold down on your machine. Do you have that option?
A shop in my area cuts parts for stages. They cut two sheets all the time. The appearance does not matter on these parts. They screw the sheets together. They run the first program to drill the holes. Then they screw the parts together. Then they run the cut program. They mostly use two screws per part. It depends on the size and shape of the part.They use a lead in and a lead out in the middle of a straight cut. They cut in two passes.
No roller hold down? Two things that do work. Screw the parts together or use double sided tape. Both will work. And yes you can cut through both in one pass if your machine will handle it.
As mentioned previously there are hold down issues.
Also weight issues.
You'll have to cut slower and likely use a larger diameter bit.
If you're really determined, try Raptor plastic nails to hold the sheets together. Easier than screws and easier to come apart. And, as a bonus, you won't get that sickening knot in your stomach when a $100 router bit spinning at 18,000 RPM hits the screw you missed at 600 IPM.
I do a lot of 3/4 ply and, depending on the bit, cut at 750 to 1100 IPM. Can't imagine you'd get close to that with 1 1/2 ply
Has anyone tried Aluminium staples?
We used to use them all the time when gluing up laminated stringers for curved staircases. In our case we just left the staples.
