Sorry Bill,

Didn't see this on the next page!

I dismantled the spindle to check the bearings as I realised I hadn't lubricated it for a very long time. I was rather amazed to find the taper rollers in fairly good condition with minor signs of wear and still grease in them.

I replaced the bearings with the same make and number which was ridiculously cheap and cleaned it all up and put it back together. I haven't re greased the bearings yet as I am nervous about overdoing it and getting grease everywhere. The minor irritation is the lack of any flats or similar on the threaded collar to adjust the spindle bearings. I wasn't sure whether or not to put a pre load on them. In the end, I just set them up with no play but no pre-load. Seems ok.

I did find that the gearbox had been greased rather than oiled but all seems to be in good condition. I have cleaned out all the grease and keep the box topped up and pump oil into the grease nipples now. It will be interesting to see if it is better.

I haven't stripped the saddle yet so have no idea what has been used for lubricating that. I suspect it is full of grease though.

I agree about the clutch. A bit scary and I haven't relied on it. I will try your idea and see if it is better.

The other thin about it is the feed lever on the saddle. Mine has a spring and a clip to stop it dropping into gear and engaging the drive. It really does do that and it is scary.

I saw the grub screw through the collar on the cross slide goes onto the thread and I can't get it off at the moment due to damage to the thread. It is all on hold a bit at the moment as I can't get the imperial nut (mine is brass or bronze and quite worn) as Myford are closed due to the virus. A chap has a nut and lead screw on ebay but it is over £120 and metric which I don't really want.
Does yours have roll pins at an angle locating the cross slide lead screw bracket? I managed to get it off but don't see how you are supposed to without forcing it which is what I did. To put it back, I will get them out and fit the bracket and tap them in again.

I saw a neat mod for it using thrust roller bearings on either side of the bracket to eliminate back lash but also allow free movement without drag. I might do that when I rebuild it. Also need the washer between the lead screw handle and the micrometer dial. Currently it locks it up when you tighten the handle.

I bought mine about 30 years ago when my workplace replaced the Warco with a genuine Super 7. It had been fairly abused for a few years by the workshop before I got it but it is still pretty good. I only paid £75 for it! I have finally decided to rebuild the bits that needed it.

Thanks for the info.

Richard.

Thank you Bill and John,
Sorry about the delay thanking you but my last attempt to post failed.
I am afraid I don't have a manual for the Warco Bill but thanks for the info about screw cutting. What do you think of your machine? I am also a bit puzzled about lubricating it. I have stripped some of it down and cleaned the grease out of the gearbox and replaced all that with oil but obviously have kept the taper roller bearings on the spindle greased (new bearings). I haven't stripped out the saddle to clean out grease yet but am assuming I clean all the grease out and replace it with oil and keep regularly oiling it. Is that what you do?
Thanks John for the very detailed dimensions for the screw and nut. That should furnish me with all I need to decide if the Myford one will work. I will post back when I have checked it all out. Unfortunately it looks like Myford have shut down as I can't get any response from them. I know Warco are shutting down shortly but they don't have any spares for the old Taiwanese Myford copies.
Thanks again to both of you.
Keep safe,
Richard.

Hello there,

Sorry to be joining on an old post but would be very grateful if anyone could tell me the dimensions of a super7 power feed cross slide nut and screw please?

I have a Warco 720 (super7 Taiwanese copy) which is not a bad lathe but the nut seems to be worn and I would like to try and find out if the Myford one will fit.

I would be very grateful if anyone could help please.

Thank you very much,

Richard.
