Drill Press Past 90 Dgrees

[JPG]

May as well since no pix will likely result in no answer.

I have a 510 and just purchased a 520. My 510 drill press rotates to 90 degrees the 520 rotates about 7 degrees past 90. I measured both. What could be the problem? I have looked at about everything and cant seem to see a problem. It feels like it might balance over if i begin using it. Any help would be appreciated. Larry

Read through the tread in this link, the original poster had a similar problem, and as others have said here, it was caused by the bench tubes not being seated properly in the end castings, (inserted past the stops).

In the second pix in the thread below note the positioning of the bench tube end up against a stop. Also note the two ribs upon which the bench tube bears.

I surmise the vertical angle problem is being caused by the end of the bench tube NOT fully inserted up against the stop. Rather it is also not extended far enough to bear against the rib nearest to the stop. This allows the base casting to acquire a cant(rotation clockwise when viewed from the operating position).

A cause may be that a way tube is being used as a bench tube. The shorter length could result in the 48" exposed measurement in spite of incomplete insertion.

I wonder if a similar situation exists at the other base.


FWIW my M5(goldie) does not have that stop.

Similar, but opposite.

Read what the OP answered when I commented that if the tubes are inserted properly into the castings then the exposed bench tubes (casting to casting) would measure 48". Can't have it both ways!

What happens when the longer bench tubes are installed as way tubes and the shorter way tubes are used as bench tubes? It simply won't all go together.

I checked again and it is 7 degrees past 90. I cant see anything that is damaged or out of alignment. My 510 goes about 2 degrees past 90 and it works fine. I put it in drill press mode and lifted the other end, it seems real light compared to the 510. The locking screw while in drill press mode is above the hole it needs to be in. I have to lean the drill press back to engage that screw in the hole. When I do that it seems wobbly with just he lock screw in place. Larry

I may have been looking at this all wrong!!! Seven degrees past 90. If this means it goes from horizontal up to vertical (90°) and then 7° further (past vertical -- no way! Without photo proof, I don't believe it possible!

Assumptions!

All the parts are as they should be.

All parts are where they should be.

Those assumptions add up to it operates as it should.

But that is not the case.

So something assumed is invalid.

I be looking at what was assumed that may be inaccurate and possible explanation for aberations.

Regardless I still think the bench tubes are NOT inserted correctly onto the outer bearing rib. I think that IS 'a way'.

Could part incompatibility due to tube diameter be a factor? For example if the base was made for the old large diameter bench tubes but the smaller diameter tubes were present? Or is there any other combinations of these parts that will go together but cause the lower Base casting to be at the wrong angle to the tubes? Just thinking out loud here. With so many parts being sold in the secondary market, a lot of things can happen. (A 3/4 HP motor in a modern 510 comes to mind.)

I'm wonder if the base casting and the base arm casting are matched. The service parts list identifies them as the 'Base for older units' and the 'Base Arm for older units', so there are at least two different versions.
