  1. While routing the truss rod channel, on what I hope to be a standard model if I ever become full time, I heard an unusual loud bit while routing the 3rd pass (about 3/32" each pass). When suddenly *SNAP!*. Now, I was wearing face protection (eyes, ears, dust mask) but I was wearing underwear and slippers!!!! (now don't tell me I'm the only one who woodworks in his underwear). The bit broke but did not touch me. I could be trying to pull the bit off of my skin right now!

    This is also proof that cheap is dangerous! this is a woodcraft brand 1/4" straight bit.

    Woodcraft cutters are worthless!

    Oh crap! Here I thought I was getting some bits at a good value. I assume you'd recommend replacing them with better ones to avoid the same thing happening?
    Maybe I should wear a cup when using these bits :bag: .

    Same thing happened to be with a woodcraft bit...except I was wearing my PJs.
    Maybe woodcraft bits are only designed to work properly if you are fully dressed? ;)

    Just take it easy,
    The more noise means there is more vibration.
    Which tells you that your cutter is bouncing/flexing.
    Badly designed cutters i.e. shear angle and relief angle
    bounce more then cut. Just take smaller steps so there
    will be less pressure on the cutter.

    I get my cutters from a local tool grinder that knows
    what he is doing.

    The Stew Mac bits are nice and a good deal considering you get 2 of the 3/8 bearings.

    I visit CBbasses.com nearly every day, hoping he's uploaded some new pics in his *the news* section..... :)
    I am SO jealous he's building a bass for Chris Wood. Congrats! Interesting wood choices you two came up with Cliff.

    Thanks guys!
    Everything is flowing smoothly. :bassist:
  14. You guys are not gonna believe this, I just broke another bit about an hour ago!!!!
    yes, you guessed it, cheap MLCS bit. This one was a 1/8" solid carbide upcut spiral. This time I was routing the graphite stick channels after I went out and bought a 'good' 1/4" to replace the broken one. ..I guess it's out to buy router bits again.

    don't try and bite off too much at a time.
  17. no man, it's birds eye maple. and was taking < 1/16" at a time with the 1/8" bit!!! it's the bits man, seriously!

    My CMT 1/8" bit (I lost it when I moved) was able to take 1/8" at a time off of Ipe without a problem!!! Also, both were solid carbide! the only difference (apart from obvious quality) was that the MLCS was spiral.

    I do alot of work in my pj's. :)

    I had the carbide cutters on a 1/2" bit shatter when routing a PU cavity in Ash. Something hit me in the stomach when it happened, didn't really hurt, but instead of the cutters it could have been part of the brass template guide fastened to the base of the router because the shattering bit exploded out the side of the brass guide destroying it. I was astonished when it happened. :eek:
  19. Brother, its time you got your self a nice little router table with a rip fence

    I do feel your pain......I was 15 at the time.....the bit was actualy a whiteside spiral.....just missed the bulleye.....nice scar
  20. Now is a good time to replace your collet. This could be a major contributor to your bit failures. You can't see if it's out of round or if it's got some sort of burr that is keeping it from working properly. Just the vibration of a bit that isn't seated and tightened in well enough can damage a collet to the point that it isn't suitable for 20000 rpm cutting. We replace ours in the CNC table all the time when we get these untraceable problems with bits. And we use 1/4" spirals that run between $18 - $29 each - we run through several each day depending on what we are cutting.
