Make sure you keep an eye on your routers!!!! Pretty sure the shop vac blew out the fire. Not sure why it went that low. There should have been a centimeter of clearance. The collet made the bulk of the burn.

Whoa. Are the other cuts burnt too? Or are those shadows?
Glad you and your barn are ok.

Oh damn, how scary is that to see. Looks like it kept going for a while.April 25, 2017 at 5:16 pm #32200
Nope, the other cuts are fine. It was still happily cutting, into the table, the other parts. You can see the line it cut, full depth in 3/4″ plywood off the board. Not sure what that cut was supposed to be.April 26, 2017 at 3:42 am #32231
Okay, so not to self and everyone else. Make sure your collet holder doesn’t hang lower than the rest of the machine. I know in theory the bit can cause a fire too, but looking closer at the damage, most of the burnt wood was just friction from the collet holder. The bit was still cutting without issues. I was trying to get that extra couple millimeters of cut depth, should have just put a longer end mill in. I have them….April 26, 2017 at 4:44 am #32236
Dang man. Lesson learned I guess. Glad you and the house are ok!

You’ve convinced me. I bought a smoke alarm and a fire extinguisher.May 2, 2017 at 1:59 pm #32609
I blame you, Barry. This is somehow your fault 🙂
I was organizing the garage while it cut, and I was just hanging the smoke alarm when I smelled the smoke. No alarm went off though. Turns out, the CAM was trying to go to -31.5mm in the Z direction. I had the part cut itself out after the pocket, so I had it go to a depth of 18.5mm, but start at 13mm. Apparently, that means it will go 31.5mm down. Ooops.May 3, 2017 at 3:47 am #32702
Yea, I don’t let the collet holder stick below the plywood anymore. At least that way, it’s the whole assembly dragging, not the large flat spiny part!
Also, you don’t need to cut the blade slot for your table saw insert. Just slide your fence over half the insert and raise the blade up through it. Makes it a zero clearance insert so you don’t get as much tearout. Make sure the blade isn’t going to come up into the fence first! I may or may not have killed a sacrificial fence face once….May 3, 2017 at 4:26 pm #32761
Note to self… always double check Barry and Jeffeb3’s work before you turn on the machine…
