Looking at the info in the manual (p. 29) regarding the taper attachment, the "block" (14) is the missing part that attaches to the cross slide leadscrew.  This doesn't look too difficult to make.  Looking at the drawing, it appears to be a simple L-shaped bracket with a hole for the leadscrew to attach to and another to engage the pin on the top slide (15).  The bottom slide (12) is one part that I am unsure of but it appears to be missing. However, there is a bolt at the bottom of the main body of the taper attachment that might be the point to which the connecting bar attaches to.  If so then the drawing confuses me...

The exploded diagram for the cross slide (p. CP 28) shows that the leadscrew doesn't attach directly to the hand wheel but slides within a keyed sleeve.  To me this suggests that there is no need to disconnect the screw from the cross slide when using the taper attachment.  If I am correct, does this mean that I can leave the taper attachment in position, with the exception of the anchor bracket when not in use?

I wish they included actual photographs rather than the drawing, as I am unfamiliar with taper attachments.  I will continue to study the diagrams but most of my efforts will be going on getting the feed working.  Once done, then the real cleaning and looking at things like the taper attachment will become more serious.

I think you are correct Ken.  There is a plate covering the front and the four rods are welded on.  To be honest, I haven't really paid much attention but will look at it a bit more tomorrow.  The chuck is 14" and the faceplate is 15"

EDIT:  I just realized that the info on the taper turning attachment begins on page 28 of the manual  This makes more sense and confirms my observation of the telescoping leadscrew.  It appears that the large part of the taper attachment in the bottom slide (12).  So it may just be the aforementioned block that is missing.

The drawings in the machine manual of taper attachment have me a bit confused as well. I do agree that the only piece which seems to be missing is that L shaped bracket, though there's likely some small spacer rings and/or nut you'll need to be able to connect that bracket to the end of the cross slide screw. You are correct in that you can leave the taper attachment on all the time as long as the anchor isn't snug. Many people remove the taper attachment when they discover they're spending far more time clearing chips off it than using it.
