High frequency points set screws

[burninbriar]

I was setting the points on my sync 250 and they keep going back to the same place as soon as I tighten the set screw. I removed the set screw and found it to be the style with a needle point as opposed to a cup or flat point. Obviously the set screws are just falling into the divot from the previous setting. I moved all the points far enough to get away from the divots and am up and running again. My question is this. Would there be any harm in grinding the point off the set screws to make them a blunt point so I don't eventually fill the point body with divot holes making accurate adjustment impossible? I don't see how it could hurt, but maybe there is a reason for using the pointed set screw.

How about just rotating the electrodes in the holder to move those dimples off axis..??

Blunting the setscrew tips is OK too....

That is pretty much what I did, The wires need to be loosened to rotate them. I just moved all three sideways to find fresh material. I just thought a blunt point screw would prevent putting more divots in it.

The reason I can think of for not using a blunt set screw would be if there is high degree of magnetism produced that would slide the points together without the divot hole to hold them. If the points came in direct contact, would that cause further damage. I don't know if any of that is true, but it could be a reason for not useing blunt point set screws.

NAH... the HF actually De-Magnetizes... so not to worry on that point..... it takes DC to make a cohesive directional Magnetic field

(Electromagnets use DC... DeGaussers use AC)

Grind away, HOWEVER do not grind the points themselves, no sand paper, nothing but a clean rag, otherwise you will remove the irridium coating

Thanks for the reply's, I might grind the screws next time the points need adjusted. The manual boldly warns about not filing or sanding the points but that is good advice.
