You won't be sorry for that purchase 92VwGTI . When you get the post also get a 1" travel indicator mount it in the post and measure if there is any movement in the chuck . What you are looking for is actually movement in the spindle . Actually you could do that before you get the post . You can get a travel indicator set up for pretty cheap . I just put new bushings in my 6" and it didn't help because the spindle was worn out . I posted earlier about this so ignore this part if you already read it . My spindle was worn down about .006 , the spindle is not made anymore and a good one is hard to get so I split the bushing on one side drilled a oil hole I installed the whole thing and then carefully tightened up the clamp . I didn't have to over tighten very much and I got the spin wobble down .001 .
I'm in the middle of a project right now , the first thing I had to do was to machine down the head of a SS 5/16 bolt . this was not a real good thing to do on the little 6" because it is a interrupted cut (no lathe likes that) , I went slow the little guy handled it . One thing it had a problem with was when facing the bolt it didn't want to finish getting off the last little ti* . One thing to remember the bolt head is hardened a bit so I didn't push the last part , I just filed it off (it gets polished with a 3M deburr wheel , last op) . Next up I needed to make some spacers and 5/16 threaded bushings . optimum mat. would have been 316L SS no way was I going to ask that of the lathe and I wanted to get this done in hours not days , so 303 was used. It's soft , the spacers (12 of them) had a 5/8 dia. and a 5/16 thru hole and 3/8 wide . Drilling went fine and the part off went so well that I could of just left that finish but I faced them to size anyway . The threaded bushing had me a little concerned because it was 3/4 wide and I had to tap all the way thru but no problem . All in all the 6" preformed well my back not so much .
