I have an older American WJ-6 Jointer that I inherited. It was poorly maintained. The knives were never replaced or sharpened. So, in my zeal one of the first things I did was to remove the knives for sharpening without marking any kind of top dead center. The fence is funny on this in that it is cut out above the cutter head and outfead table about an inch. I purchased Rochlers knife setting jig. Iam having trouble finding the tdc. Any clues?

Place masking tape over the fence cutout. Reinstall one knife. Mark TDC on the masking tape.

Simple if you have a dial indicator.

I’ll second the dial indicator. Could not have replaced my jointer knives without one.

Ill also give a recomendation for the dial indicator. I tried setting up my planer with feeler gauges and couldnt get it anywhere as close as i can with the feeler gauge. Getting one with a base will cost you about $100, but harbor freight has one without a stand for $15.

Saw that at HF. I’ll pick one up with a magnetic base this weekend.

TDC is precisely straight up from the center point of the cutter head. Once you’ve determined where that is, you can scribe a line on the fence so you won’t have to hunt for it every time.
