  • wood types and blades

    some of the projects i have done lately for christmas ornaments, i have found that with using plywood 1/8 and 1/4 inch the center plys of wood chip out , the cuts are fine but it is very noticeable is there certain blades, speed that would stop this

    Generally speaking the thinner the material being cut, the smaller the blade you want to use. Are you cutting one layer at time or stack cutting? What size & type of blade did you use?

    Also, in your case, the plywood may be contributing to the problem as much as the blade. What kind of plywood are you using? I've routinely cut 1/8" baltic birch plywood and have had no problems with voids or chip out of the center plys.

        Yer plywood sounds like the culprit and single layers is contributing. Upgrade to a quality plywood you will stop this problem.

          I agree with Mike. Sounds like cheap plywood. By the chance did it come from a BORG (Lowes, Home Depot, etc)?

            Mike's right as usual. Voids, and I would add poor gluing procedures, in the cheap stuff are the culprit.

              I use the Finnish birch plywood from Scroll Saw Patterns Plans Books & Blades for your projects - On Sale at Scroller Ltd. and the birch plywood from Sloans and have never run into problem with either.

                Yes, I would say it is the plywood that is causing the problem. I have gotten some at Lowes & it is really bad. Not only does it chip out, but, it will warp in a short period of time. Try a better quality ply & you will notice a difference. Good Luck

                  I use good quality baltic birch plywood. I make a lot of things out of 1/8 inch. I use the FD 31 tooth puzzle blades very regularly for ornaments etc. I don't get chip outs.

                    When I first started many centuries ago I used such items as old drawer bottoms, etc and discovered very rapidly it was a waste of time and effort. In fact, this Christmas I used some plywood from a cabinet shop and had the same problem. Wasted, no way to fix it...

                      Just Wondering...

                      Is the table size on the 22" hegner saw as on the 18" hegner saw?

                      With the 22" inch one you get 4 more inches of depth of cut but do you also get a few more inches of table?

                      I had to fool around with copying and taping a pattern again today. This wasn’t as bad as the fish, but still a pain. I use rapid resizer. Scan a pattern, put in size I want and it prints it out. If more than one page, it numbers each page at the top and I tape them together. Had the fish pattern...

                      Rolf, I cover it with clear contact paper (comes off clean without leaving a residue) and draw a grid for the direction I want to cut (ie horizontal or diagonal) to keep the rows even. The rest is all freehand....

                      I use acrobat reader. The poster feature will enlarge and if it goes to multiple pages it will put in cut marks. Even if the page is over letter size it will spread to multiple pages at 100%.

                      Hi Linda, great find...I think.

                      Please keep us up to date with any information you receive. I would really like to get into this, but my computer skills are almost nonexistent, I need something that a 74 year old air head 🙄 can figure out. Thanks for sharing.
