ChrisLBren Posted January 13 Share #1 Posted January 13 Hey Group, I am wondering if there is a full proof way to avoid this. I am notching pearwood using a mill and sometimes experience chipping on the cut. Right now my mill is set at a high speed at 10000 RPM and I am using new mill bits. Do I need to reduce speed here or just making many small passes at a time for each notch ? Thanks !

VTHokiEE Posted January 13 Share #2 Posted January 13 Can you show a picture? My advice might not be accurate (I’m definitely an amateur here at best regarding milling/etc), but I have added a scrap piece behind/next to parts which has reduced tear out in some situations. thibaultron, mtaylor and Scottish Guy 3 Quote Current Build: HM Sloop Echo 1781 (First Scratch Build) Previous Builds: HM Cutter Alert, Sharpie Schooner, Chesapeake Bay Flattie, Half-Hull (NRG) Link to comment Share on other sites More sharing options...
mtaylor Posted January 14 Share #3 Posted January 14 My mill doesn't go that fast so I go for thin cuts and slow movement of the cutting bit. I do notice that sometimes some pieces do chip out but I suspect it's due to the grain usually at the end of the cut.

Isaiah Posted Friday at 04:19 AM Share #4 Posted Friday at 04:19 AM Pretty late here but anytime a blade or mill passes out the back of your wood piece there will almost always be tear out. Using masking tape or duct tape at the end of the cut or really anywhere the surface is exposed to the blade. helps quite a bit. Clamping a sacrificial piece of wood on the end also helps. thibaultron, allanyed, tlevine and 1 other 4 Quote Current build: HM Cutter Sherbourne 1763 by Isaiah - Vanguard models - 1:64 Completed Builds: Perseverance -1807 - by Isaiah - 1:48 - Colonial Brig Link to comment Share on other sites More sharing options...
