I’m interested in using a wood lathe (Laguna Revo 18-36, 220 V, 2 HP) to turn metal parts on occasion. I don’t expect to have to turn metal parts often, so I don’t want to invest in a metal turning lathe. I plan to adapt a cross slide and tool holder to secure the carbide-tipped tools. My problem is adapting the typical three-jaw metal-working chuck to fit my 1-1/4 inch, 8 tpi spindle. For the life of me, I can’t find the proper adapter. Chucks for metal holding typically come with three tapped M6 or M8 holes on the back. There are a variety of adapter plates for metal lathes, but I can’t find one to fit my wood lathe. I think I can make my own by drilling holes a lathe faceplate, which is made for screwing to the bottom of blanks for bowl turning. I’d rather not do that because I’d probably get the holes slightly off-center and end up with a bunch of runout. If you have any experience or advice, I’d appreciate it.

P.S. I thought about using a metal lathe in my local maker-space, but they’re all closed due to the pandemic.
