Some guidance on spindles

[zitman]

Hi all,

I am in the throws of making a CNC router for use with plastics and was wondering what others did to power their spindles?  I am currently using a cheapo dremel equivalent which is running way too fast.  At the moment I am intending to use the machine on plastics.

Thanks

We use a Porter Cable 2.75hp router motor. However like you
it runs too fast for some of our work. Have been looking at
other options but have not found anything that would be better
that we could afford.
Hope someone posts some new info.

Both Dremels and routers are readily available with variable speed controls....

I agree.  The dremel clone I have is variable speed but the torque available at the lowest speed (which is still fast) is too low so I end up jacking the speed to compensate.

So I was hoping to find something which was capable of reasonable torque at low speeds.  And preferably cheap to boot.

If you disregard the cheap, adding a Super-PID to most any router will give you plenty of power down to 5000 rpm.

Take a look at the Sherline heads.  I have two Sherline milling machines and I like their heads a lot when lower speeds are needed.
