<div>Just thread the rotating shaft so it screws into the motor, the same way the original shaft fit into the motor. Then drill the rotating shaft for wires and fill the void with epoxy (potting) James Franklin has a site with very good detailed pictures that will help you. I personally have not done this but most if not all K250's are done this way. I am sure those that have done exactly what I mentioned will be happy to guide you.</div><div><br></div><div>Hank</div><div><br></div>

<div>Phillippe, not sure what your asking? if your asking if you can weld a fitting onto the shaft stub, I would say yes, providing you don't get the part to hot. I am not sure why you would weld it though. You can simply pot wires right in the stub hole, and I have two thrusters like that. You can thread a fitting into the stub that is a penetrator. Both options work well, but welding it will also work. Maybe you can explain what your planning to do and why you want to weld a part on.</div><div>Hank</div><div><br clear="none"></div>
