Thread: A Question gor Gatiep

Ern

The retailer has offered for me to take my tailstock in and line it up on their showroom lathe to see if my tailstock is lower than theirs so it will at least give me a starting point. If it is not then I'll take the headstock in and by this method of ellimination I should be able to resolve the problem a lot sooner. To my simple mind the easist solution would be a replacement headstock and tailstock that match but then there may be other factors involved? it can't be the bed .... or can it....

Good to hear things are moving Dan.

The bed is cast then machined, as are the head and tail stock mating surfaces, and no process is completely error free. Got a good straight edge to check the bed?

The headstock shaft and tailstock quill are bored for the morse taper, and again, only a minor error in this will give you a misalignment.

If you have or can borrow a morse taper extension, the method noted above of wax pencil resting on the tool rest and marking the extension as it's rotated in the main shaft will indicate whether there's any run out at that end.

Looking forward to the next episode }

Hi,

I may be stating the obvious but it is possible as its new that there is some foriegn matter between the head/tail stock and the bed?

Different lathe, but a suggestion worth looking at.

On the Teknatool site, they have a review on the Nova, done in the States, where they found the same problem, and it was traced to rubbish trapped in the packing grease between the swivel head and the lathe bed, as suggested below. Removing, cleaning with Kero, greasing and replacing solved the problem.

Worth a try. If they are physically of different heights, then it is a manufacturing fault that was not picked up before shipping, and they should be leant on to correct this immediately, not at their leisure!

Thanks to all that took interest in my problem, I am happy to report that all has been corrected to my very great satisfaction...

Thanks to the supplier of my original lathe (who else but Carbatec Perth) I picked up a replacement yesterday which they gave ex their stock (to be replaced by Vicmarc) and it is spot on in every respect. I wish to publicly thank all of the staff at Carbatec Perth (without naming names as I am sure I would forget someone and end up in trouble) for all their patience in dealing with a westpest by name and nature. My thanks also to Vic at Vicmarc for the great after sales service and support. Needless to say I will be a lifelong customer of both of these establishments.

regards to all

Good one Dan....glad you got it sorted out.

I just looked back...................bad news make headlines! Wen you originally posted the bad news, there was 17 posts in 2 days. Its been two days since you posted the good outcome and not even a whisper! Amazing. Well let me say: Good on Carba-tec Perth and on Vicmarc for sorting the problem out! Hope you have many years of happy turning mate

Just a shot, but I have heard of dirt getting into the Morse Taper causing mis-alighments.

Cheers!
