    I have some Hiwin HGH15 rails - if I recall correctly I have four 760mm long rails and two longer rails (1100-1200mm I think, will have to check), plus at least 10 bearings to go with them. All new, genuine Hiwin bought a few years ago before they started turning up everywhere.

    Is that one THK rail you have available to swap, or two? If it's two then I may be interested for my X3 mill conversion.

    Two rails

    Also have two THK ball screws, nuts have 6 tracks 28 OD with 30 dia thread on one end, complete with INA thrust bearings.

    They are 5/8" dia x 0.2" pitch very close to 1605 would give ~400mm travel
