Re: HBM 4 Jaw chuck for Unimat SL
|
Blimey I've been stupid now in buying a 65mm 4 jaw chuck for my Unimat SL as its really too big to use.? The 50mm really can't have the jaws reversed. I've filed over and over but NO fit at all. Now I'm absolutely stuck.

I agree, the quality it based on how good the item is. If it's cheap then the strong chance is that it won't be any good. I decided to purchase a 65mm 4 jaw with reverse jaws using the threads as indicated by Phill. The only problem (if applicable) is that it's central and not individual.
Kind regards Rob

Hope that makes sense....
Best wishes
