Reversing the 511a Oregon

[Eric Egland]

I started looking at the previous threads on grinders, but with dial-up, fell asleep trying to see if anyone came up with a solution that folks liked.
I started on my 511a yesterday and got the schematic figured out.(as wired).
One thought comes to mind about the rotation as wired. It advances the spindle against the wheel fixing screw, which is a good thing. IF A PERSON WERE TO USE OPPOSITE ROTATION, he would be WELL ADVISED to ensure that the spindle screw is properly tightened. And make skim cuts.
The mod is pretty simple and maybe already solved, so apologies if this has already been discussed here.

Been there, done that.

Somewhere around here I have a schematic on how to do it.
It involves adding a DPDT switch. Let's try this:

If you have more ?.....

511a rev.

Thanks Pat,
Ok, this has already been covered. I'm going to use a 4PDT to do the job. I just have to find one in the junkbox that I can fit in to replace the original switch and do the on-off/rev function with one switch.
Thanks again.
