Adjusting infeed table on jointer

[flackbait]

Hello,

I have read the instruction book repeatedly on how to assemble the jointer (serial number 5055681) for a Mark 5. The manual talks about a grove in the adjustment handle aligning with the semicircle in the base. I don't see it. I can get t the infeed to drop down as I turn the handle, but can't get it to go back to zero. I have to push it back to zero. To get it to zero, I have to turn the handle all the way out so it is barely attached to the threaded shaft. Am I missing something?

In the picture below is Jointer Model 620 with the early handle but the principal is the same for your Jointer Model Number 505681. The grove in the handle goes in the cutout in the bottom of the infeed table indicated by the arrow in the picture when assembling the Jointer. It is that grove sitting in the cutout that pushes or pulls the infeed table up or down.

The threaded stud with the nut and stack of washers to the left of the handle in the picture holds the infeed table on and provides the tension adjustment. The stack of washers alternate flat and spring washers.

By the way you described your Jointer as "(serial number 5055681)" but that is the Model Number with an extra 5 in the middle. None of the Jointer serial number sets ever went that high.

It will push, but not pull. How can I get shoulders on handle to slip over ears of casting. The stud and infeed table will not give enough clearance.

The 'ears' are assembled into the 'knob' groove as the two halves are put together. You will have to separate the two halves to do so. Intimidating, but not difficult.

Let me get this right. Run the hex nut on the underside with the clamping washer out far as I can. Lift up on the infeed table and drop the adjustment depth of cut adjustment knob grove into the casting saddle. Tighten the hex nut sufficiently to maintain depth setting.

Yes. Assuming the backed out nut will give sufficient separation of the two 'halves'.

The hex nut is to be tightened enough to keep the infeed table and the base/outfeed table together but not so tight as to lock them together. The combination of flat and spring washers keep the two parts together and still allows the infeed table to slide on the base/outfeed table to adjust the depth of the cut. If you do remove the nut then I recommend waxing the bare metal areas on the infeed table and the base/outfeed table where they slide together on each other. Just like waxing the table surfaces it will help prevent rust and lubricate the surfaces. The same can be done for the knob cutout.
