[QUOTE="Jinx-), post: 831765, member: 19791"] I can call mechanism to engage lead-screw or lead screw engager something... About the lathe its 10x22 and it missing some features I would like to have. Let see if you ever worked with Hardinge toolroom lathe, when threading once lead screw engaged it stays that way, but it has a break and special lever on crosslide to get in and out of thread, love that feature... Of course Hardinge toolroom lathe no longer made, but there are many replicas still build today and they still cost 20 times more then grizzly :D Here's one made by EISEN [IMG]http://img200.imageshack.us/img200/161/ci2v.jpg[/IMG] And the one from Grizzly [IMG]http://cdn0.grizzly.com/pics/jpeg500/g/g0602_det5.jpg[/IMG] Specifications: Swing over bed: 9-5/8" Swing over cross slide: 6-1/8" Distance between centers: 22" Spindle bore: 1" Spindle thread: 1-3/4" x 8 TPI Spindle taper: MT #4 Motor: 1 HP, 110V, single-phase Number of speeds: 6 Range of speeds: 150, 300, 560, 720, 1200, 2400 RPM Leadscrew: 3/4"–12 TPI Compound travel: 3-1/2" Cross slide travel: 6-1/2" Carriage travel: 18-1/2" Maximum tool size: 1/2" Tailstock barrel travel: 2-1/2" Tailstock barrel taper: MT #3 Standard Equipment: 5" 3-Jaw chuck with two sets of jaws 6-1/2" 4-Jaw chuck with reversible jaws 8" Faceplate Steady rest with 1/4"–2" capacity Follow rest with 1/4"–2" capacity MT #3 dead center 4-Way tool post Chip tray and backsplash Hardened & ground V-way bed Oil-bath gearbox Tool box with service tools Number of longitudinal feeds: 9 Range of longitudinal feeds: 0.0023–0.013 IPR Number of inch threads: 33 Range of inch threads: 8–72 TPI Number of metric threads: 26 Range of metric threads: 0.25–3.5mm Overall dimensions: 46" L x 22" W x 16-5/8" H [/QUOTE]
