Thanks Neil.

I have only just found issue 4446 with the picture on the front, I would have been another hour or so looking!.
<edit> still can't find it - it's digital subscriber content only! - it would be nice as a purchase in print form.

For me, something like this would be lovely.

Thanks for showing the photos Andrew.
I have spent the last hour or so stripping the top down, cleaning re-lubricating, adjusting and testing. I have some improvement, however, I have changed back to the old tool holder that came with the machine and raised the machine onto wood from the concrete floor. The reason for moving onto wood is that I noticed some vibration on my DTI at the compound slide before all the above work (yet to retest and check) and am not sure whether or not the finish was due to motor vibration? You mention you have 3 phase and don't get any vibration from your motor - I have single phase and I do get vibration!.
I have some feet to go under the lathe stands so I may make some washers for these and try to eliminate all vibrations.
<edit>And I had a taper of 0.04 per 100mm before, now I only have 0.02mm!!!!!

Andy F - It's a possibility later on to solder, I will run for a while and keep an eye on the joints that are there at the moment.
If I can pick up another insulator I will use that, if not I will consider soldering or uprate the existing chocolate block to a slightly greater rating, make a plastic enclosure with a perspex lid and screw that to the motor where the existing mounts are.

Andy S.

Why would the lead screw have anything to do with the finish? Surely it's the feed screw below that moves the saddle or cross slide?

Andy.

Coalburner - I must have posted at the same time!  Feedshaft is the answer.

+1 for me too - where to start?

Neil.
Extremely similar!! the width of the bands are 1.5mm pitch - not exactly the same but close enough.
What are you thinking ?

Andy.

Jut seen the specs on my previous link....and I quote 'Pitches of three feed screws = 3mm'!!!!

Thanks Jens.

I will pop to our local electrical factors as recommended by an engineer where I live to see if I can get the correct part.
I see the motor is rated at 10A and if I cant get the correct part then will use a heavier duty connector block.
Thanks for the advice again.

Andy.

Here you can see what I am getting....

It is not good...
The history of the lathe that I have is this. It was a 'bargain basement' purchase at a Warco open day around two years ago. This was sold to me with a story of another supplier selling lathes and offered to Warco - they declined as they have good relations with their current supplier and didn't carry on with the new supplier, this was the lathe that was left with Warco.
I didn't use the lathe for some time (about 1 ~ 1.5 years) as not long after I took delivery of the lathe and mill I suffered with back problems. This meant I couldn't stoop down to use them. Now I am trying them all out and sorting out any issues which may or may not always come with this type of purchase.
I have checked and tightened all gibs with little or no readings from my DTI on checking. The only reading I get is when I place a clock on the lathe chuck and lever underneath this and I get around 0.01 to 0.025mm deflection. I don't have a manual as such for the lathe so I am unsure of the allowable limits in the headstock bearings.
The lathe is a FC3200 from RiPu manufacturing, I have tried to contact these and other suppliers of the same lathe about a manual, but don't get any replies. The lathe seems to be exactly the same as this one here - **LINK**

Any advice or help would be greatfully received.

Andy.

I think I will start another thread as this will get mixed in with a different subject matter.

Andrew - When you say a badly worn hold down bolt, what do you mean?

Andy.

Temporary (or maybe permanent?) repair...

... and she runs again...
...just one last problem to sort out...

This horrible banding - ew!!

A massive thanks to all comments on here, as without them I would have blown £127 on a motor that was not required.

Andy.

Thanks Andy F.

I have already taken more detailed photos and drawn the wires on paper. I am ok with mains voltage and I am prepared to buy another motor if all fails!!! The chocolate block idea is a good one, I just need to convert the crimp terminals to get them into one chocolate block hole.... Should be easy enough - maybe just buy some really big chocolate blocks!!! Thanks for the idea and tip.

Andy S.

Hi Speedy, all capacitors appear to be ok - clean with all contacts etc in one piece.

Neil (stub) - I showed the photos to a retired engineer who has their own machines and he suggested someone very close to get an insulator block and suggested the very same as you about a loose connection. I will try that first as it will be the cheapest at the moment.

Andy.

Ah, ok all understood. As said, I will call a few on Monday. They all seem to be in the Poole/Bournemouth area.

Thanks.

Andy.

Hi Keith.

Thanks for the reply, I didn't contemplate using a repairer but I will call a few 'local' motor menders on Monday - they may offer an exchange motor? They all seem around 25 miles away from where I am in a quick Google search. The replacement motor on eBay is 'only' £127 delivered so a bit cheaper than the £200 as you have paid previously. If, however it is a little ceramic or similar insulator that is required then I could easily do that work myself.

Andy.

A good question.

I am not sure, but there is no longer a way of attaching the wire to the motor as I see it. I remember looking here when I first started using the lathe and checking all connections as the motor has never sounded correct since I have owned it (about 2 years now)!!!
There are a couple more photos in the album I have created which may or may not show more detail.

Andy.

New motor on ebay ..... **LINK**

Made my lathe go pop today.... Not with an actual pop but it made a funny sound, then...... smoke from the electrical box!!!! Doh!! Investigations this weekend me thinks.

Andy.

I use them, drills, taps etc... They all go in if they fit. Don't know about the longevity of them though as I have only recently started using them. Mine seem to withstand WD40 at the moment, but then they withstood some really hot curries too!!

Andy.

Has anyone watched Men In Black 3? The scene in the 10 pin bowling, I am sure the drill in the office is a meddings?? Just saying that maybe MiB could help?
