    I wonder how many of us actually do this - set-up a long carve, start the machine, and go to bed. I'd love to have that much confidence but I'm not sure I'd be able to sleep. Does anyone else routinely let an unattended machine do its thing?

    My question is not meant to be criticism. If many do this, maybe I'll try it. My gut tells me many don't.

    Whattaya think?

    I have had a cut out part come loose and the bit spinning in it created enough heat to start my mdf deck smoldering, and with the vac hold sys running if I had been sleeping and not checking the machine I would have most certainly burned my shop to the ground !! It was red hot and I had to use water to put it out.

    So you can let yours run all night or day without watching it but I will not.

    Just my 2 cents

    I think way too much can go wrong to justify the time saved by running the machine unattended for hours (or even minutes for that matter). I'm always within about a 10' radius or closer from my machine while it's running.........just in case.

    Anyone running a loud, noisy router should NOT walk away. That could burn down a shop. Ear protectors are also necessary.

    Woops I didn't mean to down-play you router guys. Routers are excellent! They can do as good a job as a spindle and cost so much less. But these motors weren't intended for hour of non-stop continuous use. I'd never suggest the hobby folks or part timers spend extra for a spindle.

    Joe, I must respectfully disagree on that one. I love my Desktop with spindle. The main reason is how quiet it is vs. a router. The Shopvac is louder than the Shopbot and it is no problem to have it running while I do other stuff. Listening to a router scream for hours is not my idea of fun, even with earmuffs.

    Also the spindle's high quality of cut and ability to handle occasional non-wood items, such as G-10, aluminum, and even hardened steel is a fantastic bonus. As someone that uses a SB primarily for hobby use, the increased capability keeps my machine from gathering dust.

    I'll agree that not everyone NEEDS a spindle, but it is awfully nice. I have lots of woodworking, CNC, and machining experience vs. the average new owner and can definitely say that I work on advanced projects way beyond knocking out the occasional wooden part, so I needed more than what the router could deliver. Once you have one, you'll never go back. Other than the initial $ting at purchase time, I have had ZERO regrets since the first time I heard it power on.

    Joe is the guy you outsource your CNC work to running a router or a spindle? Also, do you have any examples of some of his mechanical hold downs? I've been doing some work lately that has warranted mechanical hold downs like this one:

    I've been making a fair amount of jigs like this one lately and I'd love to see some of those examples.

    Eric,

    Let me apologize for my late response. One of my favorite mechanical hold-downs was made using Oak scraps. At one time we had a couple dozen in different sizes. The design was to look purposeful and not too mechanical. My inspiration came from looking at piano strikers.

    Yes my former employee uses a 5hp Colombo. I met him during a period when he was bending neon. It runs in the family. His father was an old time Neon fellow. That was twenty years ago. After visiting my shop several times Ron indicated the interest in dimensional signage. From there we started working
    together. He's a great guy.
