Hi,
I just got a Robbe S1387 shaft and tried to clamp it on to my Dynatron directly. However, I can only get the set screw to sit on the threads of the motor shaft. Is this okay? Or is there a way to get it to go in a bit deeper?
Thanks,
Tony

I have a Robbe start shaft, I don't see a way to change the depth of the opening. If all you need is just a little space to clear the threads, could you just cut some of the threads off with with Dremel? If so, it might be good to also file a small flat spot for the set screw to hold onto.
I think the set screw would work loose if it just sits on the threads.

Thanks Ron, I'll try that.

Thanks for the reply. I was thinking about doing that... but just don't want to ruin a Dynatron in case I don't like the shaft. I have a old starter that I can try it on first though....

I understand your concerns, use the Dremel with care and finesse !

isn't there a hole in the dynatron shaft?

if you look at the bottom of the 1387, there is a recess for a dowel
pin. I used a cut down M3 SHCS to fit that and a setscrew to hold
things in place.

There's no hole on the Dynatron shaft like there is on the Hobbico Torqmaster. The problem with attaching the S1387 to the Dynatron with a set screw there is no way to easily break it down like the way the KSJ/Sullivan come apart.

thats why I reluctantly leave the rubber cup mount on.

even if it squeals sometimes.

I'm using the rubber cup with my S1387 as well.

I drilled my Dynatron for a 3mm Jesus bolt. On 16.8 volts, the clamp on wasn't doing it. A carefully placed hole won't "ruin" the starter.
