HELP Buring Wood withTS
Happy Holidays
I could use the group's help. I've been experimenting with finger (box) joints using my tablesaw and Freud stacked dado blades. I've been using a 1/4" stack to dado 1/4" wide, 3/8" high finger joints through 1/4" plywood. Every cut burns the wood and lets off some pretty serious smoke and stink. I've tried slow feed and moderate feed to control the quality of the dado cut and not overwhelm the motor. Tips of the dado blades getting a rusty color to them as well. Its not rust as I baby them and keep them safely stored when not in use. Is plywood susceptible to burning? Am I killing my saw and blades? Any advice to cut these joints correctly is greatly appreciated Here are my tool specs: TS Craftsman 10" (model 315-228390) 1-1/2 HP induction motor developing (?) up to 3HP 3600 RPM 13 amp Freud 8" , 12 teeth, stacked dado blade (SD 208) Happy New Year Shecky remove "woodworking" to email. |

Any advice to cut these joints correctly is greatly appreciated Don't ask me how I know this, but you will get those results if the blades or chippers are on backwards. Plywood tends to stink anyway, and chip on the cross-cuts, but it shouldn't be burning. My Freud dado cuts clean as a whistle with no burning ever.

[2] Feed faster - not slower - to avoid burning. If necessary, use a sacrificial board behind the stock you're cutting to minimize/prevent tearout. -- Morris Dovey DeSoto Solar DeSoto, Iowa USA http://www.iedu.com/DeSoto |

Not unknown for a miter gage to creep or a pair of hands to allow the board to creep. How's the fit, otherwise? I use the router and a spiral bit. Tablesaw jigs always seemed too fussy. http://www.routerworkshop.com/boxjoints.html Easily made jig. Recommend old laminate flooring for the base, UHMW plastic for the fence(s). |

DonkeyHody & all the group
Thx for such fast and nice replies. I won't ask you about the backwards blades if you promise to delete my posting. My blades were on backwards. Too many blade swaps on the saw today and I didnt pay attention. Then I used all your advice (fater rate of feed, backerboard to reduce tearout) and all is great. Like a hot knife through butter. Too bad. I already planted the seed with SWMBO that I needed a full sized cabinet saw with greater power. So lets let this be our secret. For now I'll just stick with my Craftsman..until the next mistake I make. Thanks again and Happy New Year! "DonkeyHody" wrote in message ups.com...
