Lower Saw Guard Trouble

[algale]

I'm out of ideas.

I do recall someone, I think Reible, had a lower saw guard that was bent.

EDIT: Not Reible, although he commented. Here's the thread. http://www.shopsmith.com/ss_forum/maint ... 5-s20.html

In that case, I think it leaned away from the blade. A bend in the other direction might cause your problem.

Step one lose the blade stabilizer. The saw arbor is not designed to have anything but a blade mounted.

Next measure from the blade to the end of the arbor, if you have the correct arbor that measurement will be about 1-11/16. If it is shorter then that then it is the wrong one.

I notice you have the sliding outer guard all the way in next to the blade. That is not how you should have it set. It's more likely that the stabilizer is the culprit, but you should move the outer guard out away from the blade, but only to the point that it will not interfere with lowering the table.

IIUC, the distance from the quill end of the arbor to the blade must be no less than 1 3/4".

I think that maybe you do not remember correctly. A 16th of an inch is not much but in this case it could be. The arbor measures 1 11/16"

Can not tell from the 2nd image for sure but check that the quill bumper ring (rubber washer) is between the headstock housing assembly and the metal retaining ring. If they are reversed it doesn't allow the blade guard to go onto the quill far enough.

Strange that you should mention that. I too have been looking at that. In the online drawings of the quill, that part (#63, Shim Washer, 501304) is missing. It also does not exist in the later PowerPro drawings.

I am not sure that this is the root cause of this problem but it seems logical.

Using Adobe Acrobat, I did a search of the new catalog for that part number (501304). It does not exist there.

Question for Malcolm. Does your quill have a rubber washer between the retaining ring and the headstock? The rubber washer on my two machines are about 1/16" thick. Without the rubber washer, my quill would retract that much further which could create your condition.

Note: Spindle Knob is pulled away for clarification (I hope).

I must caution everyone reading this. I believe I have erred on my conclusions. The retaining ring controls how far onto the quill the lower saw guard will go. The rubber gasket is on the opposite side of the retaining ring and in no way effects the lower saw guard position.

The lower saw guard gets pushed up against the outside of the retaining ring.

Going through the alignment procedures on a recently acquired used Mark V. When I put the lower saw guard and a saw blade on the spindle, the inner guard assembly contacts the blade. How do I adjust this to give clearance between the blade and the assembly?

This will also adversely effect your ability to align the splitter (upper saw guard) with the blade. The splitter and the blade must be in perfect alignment.

Fortunately, the part still exists (if they have not run out). Sorta scary since it is no longer included in the current parts lists.

I was thinking it was item number 60 501307 but I think we may be talking about the same item. Quill bumper ring that is on the outside of the quill; 63 may be the one on the inside of the quill not sure from the diagram.
