Rotary table question, need help....

Hey fellas, sooooo while trying to get my Delta Rockwell 11x36 restored, i went and bought myself a milling machine. I also ordered a rotary table with it, and of course i had to tear it completely down, clean it and greased the worm. It came pretty dirty. See the problem is to get the table off, on the back there are 4 socket head screws and 4 set screws that came out, and now i can not get the table to turn smooth after putting the screws back in. Either its to loose, or i barely turn the screws then its so tight i cant even move it. It turned smooth from factory so i know its something i am doing wrong. Is there some way to "tune" these screws so it will run smooth. Or is there a certain order or way to do this? I also get tight spots and loose spots when i run the handle. Any help would greatly be appreciated. My manual says nothing about how to put these screws back together properly, but it does say your suppose to completely disassemble it and clean it, lol. Figures right.
 
I did post it there also, i havent received any responses yet.... it just seems like an odd setup how they have the screws like that. Id love to know how they do it at the factory....
 
I don't know the specific unit, but my guess is that four of those are for assembly and 4 are for adjustment.

If you purchased from PM, you might reach out to their Customer Service Dept. They should be able to help.
 
I'll have to look at mine... I have a China table that looks identical. Never tore mine appart. I also have a big 15" BP table that uses pin spanner wrench to tear down
 
Practical machinist might be a good place to post this question

I thought Practical Machinist made it very clear that they don't want questions and discussions from hobby machinists. Wouldn't Hobby Machinist be a better forum for this type of question?

Both are great options. How do you know who's a hobby machinist? A new machinist certainly has rookie questions.
 
Are all of the screws the same exact length and do they all have the same grip? I agree with Papa Charlie, some of those screws could be for backlash adjustment and the others to lock it in place.
 
If that was true some of Practical Machinists forums probably wouldnt exist.

When I first starting researching my lathe about three years ago, I came across content on PM saying it wasn't a forum for hobby machinists and they didn't want to discuss certain basic issues. So I didn't bother with PM anymore. It now looks like they are no longer being as restrictive. That is a good thing....

Probably because machinists are a dying breed, mostly boomers that had an apprenticeship or learned the hard way.
 
Shot themselves in the foot! They also wouldn't reply to questions regarding anything other than American equipment. If you asked a question about a Chinese or Taiwanese mill or lathe, you were shunned.


Still that way to a certain extent. Definitely don't post anything regarding an Atlas anything or a Craftsman lathe. The Vintage forum seems a little more tolerant and the moderator did allow a thread on a couple Atlas lathes that had been converted to make photo offset printing plates since it was a "unique modification". In general Chinese stuff is shunned. The Gunsmithing forum is often interesting with some posters from here showing up on occasion. You have to scroll down, it is the next forum below the vintage and antique machinery forum in the menu.
 
Yea i made a post a few years ago and got bombed cause i asked about an import lathe. Glad i bought american now, but it was alot of work getting it to where i want it. But as far as the rotary table goes i just kept messing with the screws until i got a smooth action and the locking screws were tight, hopefully its right. I sent and email to the manufacturer with no reply.

Doesn't seem to be a problem if it European or Scandinavian or the UK, they don't seem to mind Japanese as much as the rest of Asia.
