    I'm sure there must be several more people feeling in need of a replacement motor, even if they want it just in case. Why don't we ask the Joboman to find alternative motors, modify them and sell them to us?

    Ralph, hopefully I can help with that. I have sourced a motor locally and I am waiting for it to arrive. There will be modifications required to make it fit, but hopefully not too much cutting of the unit. The only drama's (for others) is the rotation speed, as I am using a different power supply, I can regulate this better.

    What I would like, if anyone is confident and handy with a multi meter, is for some one to measure the voltage across the motor at the different speeds and report back. Then I should be able to work out if my solution will work for others.

    Cheers

    This is for a CPE-2 Artikel #4060 apparent serial no. 3811.

    No load conditions.

    11 VDC - motor speed 1 - 25 RPM
    22 VDC - motor speed 2 - 65 RPM

    You're welcome. Only took a couple of minutes. I'm interested to see what you come up with as potential replacement hardware.

    Well, better late then never. I picked up my little replacement motor from my Brother the other day(he works in the engineering industry and 'got me a good price'). I finally got to having a look at it compared to my CPE2. Unfortunately it's EXACTLY the width of the controls compartment, so to play it safe, (plus I need to space it out past the rocker switch for reversing direction), I will need to cut a hole in the back side to make it fit. I also have to make a coupling and a spacer (to clear the switch) but I already knew that (do you know how hard it is to find an electric motor with a long metric shaft in this country???).

    I also connected it to my power supply and measured the rotation. @ aprox 18V, it was rotating at exactly 60RPM. @ aprox 9V, it was rotating at around 35RPM. This means that it should suit me perfectly, as I am no longer using the PSU that is in the unit. I would say, though, that if anyone was to follow my lead, but use the original 22V PSU, they may need to find something a bit slower, or throttle the motor back.

    I'll keep you posted....hmmm, now to find someone with a lathe....
