Linear Scale mountings for 500mm chinese lathe cross slide

thingiverse

Grizzly, Chester, Warco and many companies sell lathes under thier own brands that seem to be more or less variants of the same undelying chinese product, I designed these parts to fit kosher optical scales to my "Chester DB10 super" (a mid size generic chinese lathe) but if yours is also mid size perhaps they fit (or can be adapted to fit) your lathe too .. suggest you print just the front adapter (and scale Z to print faster and use less plastic) to test if it fits I suggest you print them with the T slot prints upwards (on an FDM printer, down on a resin printer I guess) Printing for real I set cura to the super detailed (0.12) settings package then set top bottom and sidewalls to 2mm to get some strength The wedges are held in with M3x25 bolts (I used cap head allen but its not critical), the wedges serve to hold the front and back supports together if you want to remove them (otherwise they tent to delaminate) as well as expand the T slot fixtures for more grip. Most FDM printers seem to print small holes undersize and the bolts will just screw into the plastic as is and hold well I didnt need to cut threads, but YMMV depending on your slier printer and settings etc. There is no need to tighten the bolts that snug up the wedges past hand tight, there is minimal force trying to pull the adapters out, they arent engine cylinder head bolts.
