Hot CV-750

#1 · March 15, 2012, 9:03 pm

Hi all,

I purchased a CV-750 tumbler and I'm measuring motor temps of 155 deg F after 1hr of operation. This is measured with an infrared sensor in a cool (68 deg) basement.
The tumbler is neither on cardboard nor carpet, it is on my workbench with only 3-4 lbs of 9mm cases in it. I can't believe this will operate for very long at these temps and I'm concerned about running this tumbler unattended (pita).
Anyone else having this issue? I'm trying to understand if this is 'normal' or whether I should return the unit.

thanks,
Leslie

While I don't have access to motor temperatures until our engineer returns from vacation, the motors are sealed, have no cooling fan, and do get hot to the touch during normal use. This is normal.

I took a old computer cooling fan and mounted it to the bottom of a plastic milk crate, wired a 12 volt power supply,plugged into a power strip and set my tumbler on top where the fan would blow up to the motor. Tumbler runs just luke warm to the touch
