Well, it's the NOISE!(David, what's the problem with the safety valve?)
Hi,Michael, did you have any problems with the operation of the crosshead? The bracket holding the two slide bars (items 21, 20 Page 4), goes below (and behind) Frame 1 (Item 13, Page 1). But then it ends up pushing the two slide bars downwards so that the crosshead doesn't slide properly. The installation diagram on page 5 seems to suggest that the tab of the Slide Bar Bracket goes forward of Frame 1 but then the holes in the slide bars don't line up. Was this an issue for you as well? If so, how did you end up resolving it?
Adding some photos to better explain the problem.

The red triangle below shows how the crosshead slide bars are pushed down due to the bracket below the frame (red arrow).

One solution would be to file off the bottom 2 mm or so of Frame 1 (green) and then redrill/tap the frame to re-align the holes (green arrows).

A screen grab from a video of the Ready To Run P-8 seems to show that that is what has been done. Compare length of yellow arrow to first photo above.

Another solution may be to install the bracket in front of the frame (see below). But then none of the six holes in the bracket line up.

Finally, for those thinking that the cylinders are supposed to tilt downwards (towards the back) -- that is not the case. The cylinder blocks have tabs that fit into the frame and the top of the block is parallel to the top of the frame. see below.

Sorry for the belated reply.
No, I didn't face this problem, however, similar ones with other items.
I compiled a report of what I experienced during the build, and discussed this with my dealer who considered giving feedback to Accucraft.
