Good to have you back Cliff.

[@CliffsShed]

Thanks Paul, stay well, Cliff

[@pdschu6599]

Glad you are doing better whatever the issue was. I really enjoyed this video and it will really help me if I need to do the same to my V10 P. Thank you. BTW this procedure of gear changing should come under the heading of "Bob's your uncle".

[@CliffsShed]

Thanks Paul, Take care, Cliff

Thanks Gary, Good to be back at it! ATB, Cliff

[@angelramos-2005]

Hi Cliff,so nice to see you again.I was missing your videos but even when I was tempted to email you to see how are things,I decided not to bother you.I keep on cranking and happy about it.Take care.

[@CliffsShed]

Thanks Angel, all is well now, can't be said for a lot of people out there. Looking forward to getting back at it, Stay well, Cliff

[@SPARTYGUSS1]

Great to see you back in the man cave Cliff . 👍😊

[@CliffsShed]

Good to be in there on these dark winter days! Stay safe Guss, ATB, Cliff

[@grahameblankley3813]

Hi Cliff Good to see you back, I think you got off lightly there,it may have cost but straight forward fix, 🇬🇧👍.

[@CliffsShed]

Agree with that Grahame, was a bit daunted looking at it but turned out to be very easy, mostly as I got the spare from Germany, they are not common, not reasonably priced anyway, but I will have a go at repairing the old one though, ATB, Cliff

[@Man-in-da-shed]

nice to see you upload, Cliff, was about to email you and ask if all was OK, will watch later, just bought a new Toy (AC/DC TIG) so going to play with that for a while

[@CliffsShed]

Cheers Ian, show us your new welder, don't know much about welding in general and even less about TIG! but I am toying with getting myself one so will watch with interest and envy! All the best, Cliff

[@MattysWorkshop]

Gday Cliff, great to see you back mate, i really hope you have been ok, that was a good easy fix for sure, that certainly does stop in a hurry which is a good thing if you power tapping on the lathe, can you possibly buy the part you need for the vfd to alter the settings, I don’t know a thing about those vfd units, never had anything at all to do with one, great video as alway, take care, cheers Matty

[@CliffsShed]

Thanks Matty, doubt if the keypad would come up on its own, Ill keep my eye out for one with the keypad, can always convert the drill press or bandsaw with one, ATB, Stay safe mate, Cliff

[@tropifiori]

Sorry you have been through a rough patch. Be well The lathe sound a lot better after the repair. Frank

[@CliffsShed]

Cheers Frank, its strange but it just feels so much nicer to use as well, never has been any problem other than the clattering! All the best, Cliff

[@MatthewTinker-au-pont-blanc]

I doubt it's the VFD brake that broke the teeth, more likely, previous user abuse! Does the lathe have a threaded spindle nose or the Emco Din bolt on? Threaded nose chucks quite often lead to abuse of gears when unscrewing chucks!

[@CliffsShed]

Its got the bolt on Mathew, it does stop a bit sudden and that must put pressure on the tuffnol whatever they are , teeth, but It has had some misuse in its time as well, so who knows, I'll just have to remember to slow it down before switching it off, until I do something about the VFD, bloody nuisance not having a keypad for it, simple to program with it! Thanks for watching, ATB, Cliff

[@acooper4482]

Hi Cliff I could be wrong but is your vfd set for a braked stop which could be putting strain on the teeth? I set my vfd so it freewheels to stop

[@CliffsShed]

It is, but the keypads not on the VFD so I can't alter it, got my eye out for the same one with the keypad! ATB, Cliff

[@samrodian919]

You were lucky finding a spare in such good condition Cliff. As you say for the time being your only recourse to not causing any damage to the new one is to slow the motor by turning the VFD down to min revs before hitting the stop button. That mate will be a pain in the arse until you get used to it! Obviously the ramp down time set on your VFD is the minimum you can have by the looks of it and it's a pity you can't reprogram it easily. Is it that you are unable to change any of the settings or you just don't know in what order the parameters are listed? Is there no way of finding out? Personally I'd put a new VFD on the lathe for peace of mind. I had my chinese Hyunyang VFD bow up spectacularly back in July after only six months of work. And as the seller wouldn't replace or repair it I decided to go for and English made VFD and I got an Invertek Optidrive and am extremely pleased with it. Parameters are easy to change and it worked pretty well straight out of the box. The only thing I changed really was the ramp up and down times which I have set for 3.5seconds, a nice speed as I'm not in a race to get things done and even though my chucks are bolted to a register flange, if it were a threaded nose on the spindle it would not unscrew the chuck like yours would if it were a threaded spindle! Have you considered taking out the other Delrin gears and filing the damage on them and smoothing the entry onto the steel gear? Or making new ones? Work for you I know lol. Glad to see you back Cliff.

[@CliffsShed]

You are right, remembering to slow it down is harder than it should be! its the actual keypad that's not there, as they made them up in a sealed unit they obviously had a couple of keypads and just buy the bare units, if I had the key pad it would be simple, I am on the lookout for one with the keypad, I can always use it on something else and it'll be easier than putting a different one in. And you say the chinese ones are ok, and cheap, but you get what you pay for. I did toy with the idea of having the spindle out, but I think I'll do a bit of investigation on the old gear to see how the tuffnol/fibre bit is actually attached before I have a go at it! Stay Well, All the best , Cliff

[@Xynudu]

Gear damage is pretty common with the Emco's apparently. I would try and make up an aluminium gear replacement as you suggested. Cheers Rob

[@CliffsShed]

That does seem to be true Rob, and I know its intentional to stop other damage, but I think it may also be a cash cow for the emco spares dept! ATB, Cliff

[@BasementEngineer]

A friend of mine and I have identical V10-P lathes, dated 1976. I bought mine second hand from the estate of a friend of a friend. I have never had any difficulties with any of the fibre gear. Neither did my friend, who used his in a commercial operation until 5 years ago or so. But here is an interesting observation. Although my friend used his commercially, mine was not, not even by the first owner. And yet, I had trouble with the electric switch, which my son managed to repair and, most irritating, the spindle bearings in my lathe are definitely rough and noisy, needing replacing. On my friend's lathe the spindle bearings are still smooth as silk. Go figure. I would conclude that Emco Maier may have had difficulties in quality control, and that components varied greatly among production batches of parts and material.

[@retromechanicalengineer]

Great to see you back Cliff, you have been missed. Thanks for sharing that experience, I will watch out for that when I VFD my own V10P. I have recently moved so am yet to sort out the new workshop. Stay safe and best wishes. Dean in Oxfordshire.

[@CliffsShed]

Thanks Dean, good luck with sorting your workshop, don't hang about, its surprising how quickly you get a bit rusty, as I am finding out! :-), ATB, Cliff

[@retromechanicalengineer]

@@CliffsShed Thanks Cliff.

[@hhfuglse4960]

Hi Cliff Really nice video :-) Where did you buy the gear you are replacing? I have an Emcomat V8, which has lost a lot of teeth on the fiber gear that sits on the spindle shaft. But I can not find anyone who will ship to Denmark :-( Best regards Henrik

[@aceroadholder2185]

The reason I'd rather have a belt drive lathe in the home shop, less to go wrong and easier to fix. To save your new gear a VFD controller needs to be at the top of the list of things to buy. Glad you are better. Hard to shrug off stuff like we could as young guys.

[@CliffsShed]

True, There aint' much fun in getting older! Stay safe, Cliff
