Adjusting the stop bolts for the main table at 90degrees.

[Ed in Tampa]

I just ran into a problem I thought didn't exist. I was drilling through something that was about 4 inches thick and I noticed the hole was not vertical.
I immediately got my square out and checked and sure enough the table stop bolt was to high and caused the table to be tilted slightly less than 90 degrees. I cranked the bolt down until the table was at 90 and redrilled my holes.

Now I'm want to go through my alignment to make sure first my trunnion holes are of the proper size, and that my table is in fact in proper alignment.

Here is my question there doesn't seem to be a way to adjust these stop bolt on the 90 degree setting with the table in down on them. It is more or less a trial and error type adjustment. Tweak the bolt place the table against it and check for 90 perpendicular between the table and the quill. No big problem except unlike the one stop that is used for 0 degree setting the 90 degree setting has two stop bolts. On front left corner and one on the back left corner.
How do you adjust both to make sure they are touching the table but not holding it up or below perfect alignment?

If there was room you could adjust one to perfect alignment and then using a .001 feeler gauge adjust the other until it just touches but I don't see how to get my body twisted around to be able to do this with any accuracy.

How do you guys adjust both stop bolts so they are both holding the table at perfect 90? Since there is only one stop both holding the table at 0 degrees do we even need to have two for 90 degrees. The one on at 0 degrees works on the trunnion where the two contact the actual table.

This is the issue I ran into when using the OPR in vertical position. Nick said it shouldn't happen if my table were perfectly aligned in the first place.
Taking that with a grain of salt - I used the same method as you have thought of - TRIAL AND ERROR~ It worked to my satisfaction with minor adjustments. The horizontal alignment is still (as far as I can tell) perfect.

Ed....I don't know how old you are but this body is about 70 and believe me, I know about this twisting thing. I also used a .001 feeler and then just a tad more and it worked for me.

Got Milk? Got a foot stool. orange crate, 5 gallon bucket, small step ladder?? These all work as stools.

If you look around in almost any photo I post, you'll see a five gallon plastic bucket with a wooden round seat. I have three or four. There's always one available when I need to get down low.

Now we have the stool.....My back is better. We can all down there now....

What's the advise for the eyes that can't see up close? Doc

Chiro;
I hope you can follow my logic on this.
At one of the TA sessions I attended a long time ago the instructor showed how to check the table alignment using the saw blade.
Make sure that the table are 90 deg to each other in the sawing position and then move the table away from the blade and turn the table to the drill press position position but do not raise the machine into the drill press position. Move the table back toward the blade and advance the quill until the blade is very close to the table and select one tooth of the blade to make the check.
This tooth should be the same distance from the table at the top of the rotation as well as the bottom. In fact the blade tooth should be the same distance from the table at all points of rotation and if it is not then adjustments are necessary.

Back up some!

Bill - I follow the logic on this, but isn't it more direct to square the table to a machined rod or a drill bit from vertical position? His method will work, but sounds a bit like using a rectal scope to see if a guy has tonsils!

Thanks guys. I was really off on the wrong track. I thought we were trying to set the 90 degrees stops on the main table.without getting a kink in the neck.

Can you really check tonsils with a rectal scope these days? Boy am I glad I had my tonsils removed!:)
