Thanks for finding those drill chucks on eBay, but the 5/16-24 external post on the chuck that I have is hard to pin down.
The DeWalt ras motorshaft has a 5/16-24 female thread on the accessory end.
Do you know of an "adapter" that I can use to upsize to the chucks you suggested?
It would have to go from 5/16-24 male to 3/8" 24UNF male (or larger) to use the drill chucks on the market. So far I haven't found one.
I thought this would be a great upgrade for my drill. BIN on Saturday. Showed up in my mail TODAY (Monday).drill chuck at a great price

Here's little tip chuck up a 1/2-20 nut in the lathe ,that way you will not screw up the threads on the adapter but I'm sure you know that.
