I'll try to describe my David as someone requested... ;D
The bed, in stabilized cast iron is very rigid. It is very well machined and free of any flaw
Headstock is an Enbloc, well sized and machined with accuracy.
Chuck spindle: The chuck spindle rotates on adjustable TIMKEN taper roller bearings and really free and without any noise.
Drive system: Machine drive is obtained by a set of pulleys and V-belts and mine had a modification now It has a inverter control system so I use just two mechanical combination, slow and high position, and the infinite variation by the potentiometer.
The automatic work feeds is really useful. I requested to Ceriani factory a little modification like the reversing gear system so Im capable to do a reverse treading!!
Carriage: The carriage with apron is well proportioned and slides on dove tail guide ways protected by oil scrapers; it is fitted with a self-adjusting jib. Traverses take place by means of a hand wheel and rack gear.
Saddles: The saddles are sturdy and easy to adjust, equipped with precision screws mounted on ball bearings and with well engraved adjustable vernier. The adjustable tailstock is also equipped with a adjustable vernier and it turns, unfortunately, counterclockwise. I contacted Ceriani brothers several times suggesting the modification of that rotation sense. The quick blocking happens, without any hesitation, through a comfortable lever.
The pivoting protection screen and the carter door are protected by micro switches
I had also the two chuck, a three and four jaws, mounted on the back plates by Ceriani. I adapted another back plate on the 5C chuck . Now I can change chucks without losing precision. I didnt measured the backlash but the resulting works done until now seems To be really precise.
Compared to other lathes of the same category I preferred that lathe due to the 32 mm spindle hole
and his relative light weight, 80kg a really bench top lathe, instead of 180kg for a similar lathe.
