The mini lathe takes a 100mm 3 bolt chuck type K11 but there is no suitable 4 jaw available, so I bought this 125mm K72 4 bolt chuck and made an adaptor to fit. A K11 160mm face plate has the register and bolt pattern to fit the lathe spindle, all it needs is the face turned to replicate the K72 register with 4 bolt holes. This took a couple of hours to achieve and the chuck was finally fitted. It ran true but is a lot heavier than the 100mm chucks, made worse bt the cast iron face plate, so the face plate was reduced in diameter to 125mm, which noticably reduced the inertia of the whole set up. The chuck needed a strip, clean and greasing before use, one jaw was noticably tighter in its slot so all four were changed around until the best combination of fit was found. One is still a little tighter than the others but it will wear in with use. This is a nice chuck and the extra weight is quite useful to keep heavy cuts going smoothly. General advise is to use a 4 jaw chuck one size bigger than a 3 jaw and I think that is correct, it will enable holding of rectangular pieces with the jaws as far out as needed, as long as they clear the bed of course.

Non capisco perchè, in catalogo, lo stesso mandrino da 125mm nelle varie configurazioni ha attacco posteriore con 3 viti e 4 viti, ma nel dettaglio del contenuto è indicato 3 viti su tutti (K11-125 K12-125 K72-125). Io ho ricevuto un mandrino con atacco a 4 viti.

Mandrin de bonne qualité, reçu rapidement (4-5 jours) région parisienne. ....................................................................................................................... .........................

PARFAIT

tutto bene, articolo arrivbato velocemente, non è stato ancora montato però a prima vista sembra di buona fattura, sono soddisfatto

Both items are of good quality and fulfill my needs. Take them apart, clean them, and grease them with a quality grease and your good to go.

The 4 jaws of the 5 inch chuck move smoothly and seem to have a nice fit with the main chuck body. I made my own backplate and ended up with only 0.0025 runout when running my dial indicator on the outside of the chuck (which I was very pleased with). It was well packaged and arrived ahead of schedule.

Le produit est très bien fini. Il s adapte parfaitement et son prix est très intéressant. Très pratique, je recommande.

Good value for the money

Ok so I purchased 4 independent jaw chuck because its the only way I can work on shapes other then round. I never owened anything other than a three jaw chuck, so it was a learning curve. Quality and precision: My Vevor lathe came with a three bolt stud mounting pattern, and new chuck has a four hole mounting pattern.at first a bought a four hole backing plate to later realize my backing plate is pressed on. So new plate was a waste of money. I wound up drilling my original backing plate , to work with the four hole new chuck.After mounting up everything my runout turned out to be .002. Now that was a surprise to say the least. I very happy with purchase. I would definitely purchase again.
