Hi MikeMin Welcome! You'll find this forum extremely helpful and very friendly. Cheers from Perth Joe

Hello all Ken: Thanks for all the info. It sounds like you've done a lot of work tweaking your lathe. I guess I am fortunate enough to not have had those problems on my 7 x 12. Apart from the standard mods, mine worked pretty well out of the box. Bob: Replacing the cross feed nut and screw...

To the collective wisdom: Please accept my appreciation and gratitude for all your help and advice. Now that we've discovered the cause, the hunt goes on for the solution. :-) I'll dismantle the saddle and have a look at the halfnut cam mechanism and see if there is anything obviously amiss...

Ken, what a shame about the locknut and thanks for the heads up. How would you suggest to undo it without busting it...for those that live by the big hammer ;D Vic...variable speed drive is the next project. Having one on the mini lathe sure spoilt me. ;D ;D ;D ;D ;D Eureka!!! I think I...

Hello Ken Yours is even weirder than mine is! :-) I take it that you have powerfeed to the y axis? You might be on the right track with that cyclic vibration you describe as it seems to affect both axes. My lathe seems to run pretty smoothly but I'll disengage the drive to the spindle and...

I hope I'm not violating forum rules by placing this link to another BBS forum but it might be of interest. If I am, mea culpa, mea culpa, mea maxima culpa. http://bbs.homeshopmachinist.net/showthread.php?t=36425 Consensus seems to point to a bent leadscrew. I'll take mine off this evening and...

Thanks a lot for such interest in this problem. I am very impressed by the assistance you have given. Ken: That is EXACTLY what I'm getting. Does it go away if you manually feed with the saddle wheel? How about turning the leadscrew by means other than the gears? Marcello: I will try your...

:bow: Thanks for all the input and thoughts. Very muchly appreciated. I'm at work now and I will have a look at a few things when I get home tonight. Just a few thoughts and comments from me: I have a 7 x 12 asian lathe that I've had for about five years and get very good results even tho my...

Hi Dave I've just measured the saddle and compound movement in relation to the bed and I can't get more than a thou movement in any direction. In a way this is good but not for the purpose of this exercise :-( Joe

Would an imperial leadscrew fit on to a metric halfnut enough to work badly..or vice versa? Or is the size difference too big for a No-Go situation? Just a thought. Joe

Hello Jason I'll try that later. I measured the l/screw runout by resting a ruler against the rotating leadscrew and put a dial indicator on the ruler. I did this with the half nuts disengaged and also engaged. Not very precise but effective... :-) I know what you mean about the lifting...

Hi Dave OK, No seperate power feed clutch, so you engage the half nuts for power feed ...correct? Yep, that's right Additionally, can you take a picture of the feed selection knobs/settings? Done. :-) Is there a stud gear change and what have you go on the stud? ermmmm...stud gear change...

Hi Dave The feed rate was set to .063mm/rev (.0024") by default so I put a bigger gear on the leadscrew to slow it down even further. I went from 104 tooth to 120 tooth. It didn't make a bit of difference. :-( Cheers Joe BTW this is the lathe in question:

Hello all I just got a brand new G0602 lathe. It is all good except when I use the leadscrew with powerfeed. I get these bands (see photos) on the surface. They are quite rough as can be seen on the pix. I tried the ff: 1 changing gears, 2 different tools, 3 hard/soft materials, 4 various...

I've used brake cylinder hones before and they work very well. They are good down to 1/2" bore and relatively inexpensive on fleabay. HTH. Cheers Joe
