mine was horrific when it arrived on the pallet. I think enco took out the instruction manual because they said enco on it.... almost nothing worked.the transverse was way out of adjustment, asw ell as needing machining to bring the worm gear up so the lead screw wasent pulled down atleast 1/16".the linkage wasent even close to being right..the gears that go on to keyed bushings were way off center.it was the bushings, so I used my small lathe to center up the bushings inner hole and add a bush to them, so i have bushed bushings....that was most of the horriffic gear train noise that could be hears all over the shop. the motors tiny bolts were broke off the lathe bed, the head stock was way out of alignment.so much rong stuff I cant remember it all. the coumpound slide's lead screw was not true,& wobbely in the holder witch had a big hole in it for the wobble.I made a new holder and put 2 ball bearing's in it there.one on each side to take thrust.Ill do the same to the cross slide at some point...I may already have.. under the bed the bondo was all caked up so the tail stock could not slide... spindal nut was loose... I reworked the tail stock,dont remember why...and more, much more.put good hinges on the gear door.I may of made it eazely removable I dont remember. the belt tensioner was wonkey,,I added a start stop emergency switch box so I dont have to. reach over it all and flip the forward/reverse off switch..I worked ofn the change gears.deburring and polishing the rough shaft, they run quieter now, i also added moly lube to them. someday Ill remove the saddle assy and put a cover over the lead screw.I also deburred the lead screw, it was like they cut the threads with a rock...very jagged. as well as added a ever so slight chamfer to the key slot..one gib screw was striped...Im thinking about remachining the V and adding a brass gib between the steel one and the lower way.so the brass can be snuged up beter and the steel one spreads the load of the adjustment screws to eliminate tight&loose points for a better fit. while I had it all appart I also drilled the back of the bed for dro scale. as well as the cross slide.but have yet to instal them, i was going to use the battery operated ones I had on one of my mills when I put a glass scale dro on it....but wit the prices right I just bought 2 glass scale type dros.one for each. but not enough room for the glass scale on the cross slide...so I never did it..I also added a new 6" chuck, and bought anew 5" 4 jaw too self centering on both.I may get a independent 4 jaw at some point.I used the one that came with the lathe. what a pos... I also ordered a mt3 or 4 whatever the head stock is aliginemnt bar to get it perfect....ya perfect..the bed flexes so effing bad. it needs to be mounted on a 3/4~1" steel plate to eliminate it... or concerate.....but it's ok for what it is. it's too small for what i needed it for... but somehow I did that job on my 7x14 mini....go figure. although I havent messed a lot with it for that job so it may do it...but I doubt it I think I need a 12" but the price was right on this one...and I didnt have the $ for the 12" lathe. I have a lot of enco ****. I even have a enco mill drill from 1975 . it almost looks new. I havent used it since I get my 9x42 birdgported mill.that ws back when some good stuff was comming out of enco.but most is junk if it's got the enco name on it..
