Sounds like you might have watched the same video I did. I used this method and it worked great.Sazerac81 wrote:Yep TDC as set up by a dial indicator gauge and then reconfirmed after setting all 3 blades. Really does speed up changeovers!JPG wrote:The mark is at top dead center?

Actually SS says to use a steel straightedge but you are correct, that is all that is needed. That is all I have ever used. The same with the planer. The knife setting gauge that comes with the planer works perfectly. If you don't have one they are $8 from SS.garys wrote:Somewhere in the documentation Shopsmith sends with the Jointer is a very simple way to set the blades using a simple block of wood. Nothing more than that is needed to get it right.
Which is why there is no need for fancy magnetic gauges and other stuff. The published SS method has worked fine for 60+ years.JPG wrote:The video and the magnetic holders work with jointer heads that have the knives floating and are clamped when the blades are 'held' by the jig.
The SS jointer blades do not float, but are adjusted with the height adjusting screws.
The 'gauge' made in the video could be useful as a checking gauge(similar in use as the planer gauge).
EXACTLY!!! Once set they will not move.JPG wrote:And the blades are not subject to 'slipping down'.

What happened to the "hat"?
With the block of wood method the blade only touches wood at the TDC of the rotation regardless of the width of the blade due to sharpening. All blades will be in the same reference to the tables even if the blades are not the same width. (due to sharpening) I have used the magnetic holders and have not been happy. I get very consistent results with the owner's manual method.

It dry rotted!
As the blade narrows due to repeated sharpening. TDC will change relative to the angular position of the cutter head. Yes it will remain directly above the axis, but the head will be rotated differently.
I am not satisfied with the SS M VII logo, but it will have to do for the time being. It is a scaled down version of -
