i have been going slow with the new "used mk 7" haven't had alot of free time. i started off checking alignment and discovered that several of the leg bolts, lift assist bolts and caster bolts were not real tight, so i backed off went to step one off install and setup, everything is falling into place BUT when i have her in the vertical position the way tubes are not a true 90 deg. i put a level on in and in vertical im about 3/4 a bubble. the detent screw is off a bit but i think if i remember that is correct but im not sure on the way tubes ?

so in a nutshell when you all have yours in the upright position are the way tubes true level ??

the pics are 90 degrees out, they should should the level up and down 90 to the left. im watching the bubble on the right, hope this makes sense

also i checked the same thing with the table lifted on the other end with the same result


thank all

Troy,

This is a looong thread linked below, but it discusses what you are asking, I believe. By the way, there was A LOT of confusion on this thread until everyone understood what was being discussed. Hope this helps.

By the way, you can read my post at the above link by clicking below. My Mark V doesn't have this issue, but others on the thread did have a problem with getting 0° or 90° for their bench tubes and waytubes.

No worries. Sorry I didn't post more detail earlier, but I felt like enough had been said on that other thread recently. It was quite eye opening and informative. Which way is your machine off? I couldn't quite tell from the pics. Keep in mind that the bench and waytubes have to be fully seated in the bases as well. If not, they can cause some offset as well and risk coming out. Can you post a pic more zoomed out so that we can see if your machine, when vertical, is under (say 89°) or over-rotated ( say 91°)?

It "should" be slightly shy of 90°.

Now about the table???

the tubes in the upright are just shy of 90 about 1/2 a bubble and the same on the other end in the upright, but in the horizontal she is dead true, and the table to quill is true, every other item i have checked so far has been close as possible.

So all is nor . . typical.

IIRC Dusty mentioned, either in that other thread or one of its spinoffs, something with Double Tilt (DT) being different. A Mark 7 is DT. I also use DT but didn't see the difference. Perhaps now is the time to ask what he meant. I do know that there are at least two versions of the DT Bases, that is at least potentially relevant. Mine are the new style, outwardly identifiable by the black knob. I think there are other differences, but don't know what they are.

Point me there. I was not able to find what you might be talking about.

I do consider the DT to be easier to align and I believe it is because the two end castings are "identical" (no base arm assembly and no tie bar). The way the Bench tubes are set into the castings (against identical physical stops) also contributes to simpler and more accurate alignment.

I think Dusty's comment had to do with the double tilt not having the alignment issues that the original headrest had since the two bases are now identical.

I do not recall any one measuring the tilt to the left 'verticalness'.
