Helical Head Jointer Adjustment?

[Derek Arita]

Can I rest then end of my dial indicator on the body of the head or does it have to be on the TDC of a blade edge?

IMO always reference the actual cutter.

I use the head because it’s roundness is easy to reference. My suggestion is with a knife head those insert head don’t give much up for measuring.
A button tip is better then a flat tip the button tip actually has a small flat area on the tip.
Good Luck

Ya. I know you’re right. That way I know the cutter edge is even with the table, or maybe a a smidge higher?

[Andrew Hughes]

If your trying to set the outfeed table to the height of knives using a dial indicator is the hard way.
The best way is to let the cut determine the height. Lower the outfeed take a cut on a fairly straight boards edge until 4 or 5 inch hangs over the outfeed. Then raise the outfeed to barely touch bottom of board.
If your not trying to set outfeed height I apologize for assuming you were.
Good Luck

I would us the head to get the head parallel to the table.
Then reference off the cutting edge to set the table co-planer to the cutting edge. Way to much math and geometry to set it from the cutter drum.

I set the table parallel to the head, then set the table height by measuring from table to knife or insert.
