A serious concern I have is 'he' seems to think modifying standard parts is the 'solution'. That is not a likely event.
Nowhere is the interference being described nor located. That is where our attention needs to be directed.
This simply does not add up and something is not as it should be.
It amazes me that with more than one respondent requesting a full profile pix that it has not been provided.
I cannot imagine what is causing this problem assuming correctly assembled parts. I have to assume something is assembled incorrectly.
More pix with all the details in one view is sorely needed.(that full profile operator side pix).
Now the following is pure speculation since I have never laid my hands on the new double tilt base.
Is it possible that original and double tilt parts have been mixed. i.e. a double tilt way tube casting and an older hinge base that does not have the same hinge pin location??? That is somewhat unlikely since the od of the hinge pins are different. I be grasping for ideas here.
I typically will persevere with newbys since I understand their lack of experience and knowledge. This time however, my tolerance is being sorely tested.
Please sconi post that pix.

Went back and 'discovered' the following in an earlier post.
"the problem is the same with or without the lift assist connected, and existed prior to installation of the lift assist and even before the double lift was installed as well."
This has to be a clue.
Since the entire base castings are replaced and the problem continues, there has to be something amiss in the base assembly.
That essentially means the bench tube/base casting positioning(what else is there?).
I speculate that the bench tubes are not fully inserted into the base casting and the entire base casting and leg are skewed(the bottom of the leg is splayed outward).
20° seems a bit severe, but again a pix of the entire side view would be quite helpful.
To repeat something previously said, the bench tubes MUST be fully inserted into the casting all the why up to the 'stop' (or just short of the spt mounting tube location). Earlier pix in this thread illustrate that.
Now if the way/bench tubes are interchanged as has been suggested above, the 52" 'bench' tubes will tend to be short and contribute to inadequate penetration into the base casting. The 52 3/4" 'way' tubes will also require moving the hinge part of the base casting further apart thus again making the base casting/'bench' tube positioning incorrect.
Realize that 'way' and 'bench' tubes mentioned in the previous paragraph are referring to them being swapped/reversed. The way tubes normally are 52" and the bench tubes normally are 52 3/4".

This is the same conclusion I arrived at yesterday. I just don't see anyway for anything else to cause this. At this point I'd say I'm 98% confident.

Are they seated further into the castings than they should be.
I'm curious. What is the length of the exposed Way Tubes. Mine are almost exactly 48" (casting to casting). This would tell you whether the tubes are properly inserted or not.

An indication yes, but an incorrect tube will alter accuracy of the result. i.e. a short(52") tube would yield 47 1/4 if inserted correctly but could yield 48" if not inserted fully. If it is greater than 48" with either tube, that WOULD indicate inadequate insertion. A starting point to check fer sure.
Wonder where Sconi disappeared to?
Oh and Happy Thanksgiving ALL!!!!!

The tubes had been mentioned by myself and others as being a possible cause for this specific phenomena but thinking about it I don't really see how.
However, a bench tube properly inserted goes in 2" =-1/16" so measuring the exposed area of the bench tubes at 48" is a strong indication that the tubes are properly inserted. Deviation from that measurement indicates a problem.
I do believe that we would have to "work hard" to assemble a Mark so as to produce this problem.
Only the OP is going to be able to answer this mystery -- and I don't see that happening.

Let's see ... 52 3/4 -2 -2 = 48 3/4 ... 52 - 2 -2 = 48
Sure about that 2"?

Sconi may never come back to clear up this mystery but I have given it some more thought anyhow.
I now have doubts about the images that we have seen. I am not convinced that they all depict the machine at the same time.

This image shows the relationship of the safety lock pin and the indenture in the Pivot Arm where it seats. Comparing this shot with a similar view from the OP, I would conclude that the Pivot Arm is fully rotated to the drill press mode; however ----
I do wish we could disconnect his lift assist to see if that changes anything.

I share your skepticism that all three(this forum posts)pix are of identical positioning. It simply does not 'compute!!!'.

And the title of the thread is certainly misleading as we saw a picture of the lock locked.
Could this be a catfish post?
