I bought an Eisen 1440E lathe (Taiwan made) a few months ago. I’ve been researching chucks, and I happened to find a good deal for what I was looking for on eBay.
I found a Pratt Burnerd forged, adjustable “Setrite” 3 jaw chuck, 8-1/4” with a d1-4 backplate, for $500 - it’s like new. I adjusted it to within .0005” using a ground rod. I am amazed at the difference in repeatability between this and the 6” Chinese chuck I was using.
A 50 pound chuck isn’t too heavy for a solid 1440 lathe is it? I definitely notice a difference in the time to spin up to speed. The lathe came with a 2HP single phase motor. I’m switching it to a 3 phase with VFD soon, won’t this help with the spin-up?
