I have a Davinci, with 12" x 10" work envelope, would really like to have 24" x 10", so I can work on banjo necks and fingerboards without having to tile (which had worked just fine up to date)

Wondering if anyone has done this, or is it just not worth the effort and better to get a new machine?

I have metalworking experience, Bridgeport, lathes, etc, but am an electronics newbie. Also have some old Techno gantry assemblies that could probably by adapted.

I love the sturdiness and accuracy of the Davinci with the fixed gantry. I upgraded to Mach 3 and a Gecko G540 a few years ago, works great.
