Hi, 

I just noticed that I am missing a screw on my M-One motor. 

Is it bad to use the motor as is? Or should I stop using it asap? The gear has a very slight play, not sure if it was like this before or not...

Does anyone know where I can get a replacement screw I'm in NYC? I'm scared of sending the motor in with all the stories I heard about servicing.

I believe they are M2... I never measured the threads of the motor I had here, but it looked like M2 and fit a metric alan key, so im pretty sure they are M2. Length about 6mm. 

 

Ask for cap head.

Thanks Peter,

I ordered the screw. It's actually 5mm long on mine (without counting the cap head)

The screw head actually snapped in the motor. Any idea how to fix this or does this mean it needs a trip to the factory?

hey Victor,

 

an experienced machine shop owner will be able to drill a smaller shaft in the middle of the snapped screw and reverse the rotation of the drill and unscrew it. there are special drill heads compatible with this very precise work. you should find an experienced machinist in your area. it happened to me before and it is not as big of a deal as it seems.

 

fly safe.

You need a drill press and a left hand drill bit. If those screws are stainless, it's going to be almost impossible next to that soft aluminum.

Mm yes, thats not that good. Whatever you do, do not remove the screws in the stainless ring, the bearing underneath is pretty fiddly.

 

If you get stuck, send it to me, we can spark the screw out with the EDM hole burner and replace it for you.

 

Pete.

Loonworks still exists,  unfortunately Don, doesn't seem to want to keep up with the business or is just unable too for whatever reason.  I wish he would just let us all know what the scoop is.   I would send all repairs to Peter Hoare  =)

Peter's motors are nice. I might just replace my M-1 for the peace of mind.
