Apparently the Powermatic 3520 has gone through at least 3 revisions since it was introduced. If they were to offer another revision, 3520C perhaps, what improvements would you suggest?

Being able to rotate the headstock 360 degrees would be nice.

Better access to work near the headstock.
A cone shaped spindle housing similar in configuration to the Robust American Beauty or the Oneway 2436, and get away from the square headstock design. Not sure if they copied that feature from Stubby or not, but getting behind the turning to make cuts on the back can be greatly enhanced by the cone shaped spindle housing.

Better banjo that will hold the tool rest firmly.

Agree with above but little things also:
1. A better locking mechanism with multiple positions ( at least 8) to hold the spindle when sanding. The index pin is ok for indexing, but not practical for quick use.
2. A spring on the locking lever for the tailstock to hold it up for sliding and not require holding the lever to move the tailstock. I use rubber bands, but real spring would be more lasting.
3. Better door on the tailstock. I am tired of having to rework it .
4. Fix on the tach pickup to prevent loosening
5. Better etching on tailstock shaft. I have about worn mine off cleaning off pitch and sap from green wood.
Ask me later what I really think. I do like my 3520B but there is always room for improvement.
PS - I was encouraged to buy a 1 - 1/4" extension when I bought my lathe, and it has really helped at times to get the access behind the chuck that a cone shape head would do.

I sure would be interested in finding out what you folks cannot do at the back of the work piece on the PM. And if your complaining why did you buy that Grizzly? And Thomas what are you doing to that little door :>)
No complaints Bill, just thinking about lathe design in general. I really like my Grizz 0766, and have turned on numerous 3520b's...have a demo next Saturday on one. I like the 3520b, but if a new generation would come out like the OP mentions, then what improvements could be made....well, here is a list for starters, some from 3520b owners.

Agree with the better spindle housing and the lathe should also come with a settable spindle lock so people don't have to rig an aftermarket solution.
However, the biggest improvement I would love to see is something that wouldn't even require a lathe redesign. I'd love to see a tailstock riser available on a slightly bigger lathe extension kit, a la the new Laguna.
Stainless steel ways! And a 3hp motor. Ditto for a better tool rest lock and spindle lock. It seems like right now the spindle lock has 2 positions that are 180 degrees apart. Something quick like the Vicmarc spindle lock would be nice. Plus something that prevents the lathe from starting if you accidentally leave the spindle lock engaged.
That door on the tailstock scrapes skin off my knuckles every time I open it. Anybody up for a class action lawsuit?
For small spindle work its difficult to get a skew in at the "correct" angle near the headstock (for some value of correct). Its not so much that the tool hits .. much.. but it kind of gets in the way of the rest of my posture. This might be partially technique problems on my part, but rounding off the corners of the headstock would completely solve it. I also purchased a MT extension to help with this, but dislike it as a solution in general (its a smidge fussy imho).
You might ask why I'm doing small spindle work on a 3520 - legitimate question.. its because I only have one lathe and use it for a wide range of projects
