<https://lh3.googleusercontent.com/-kyY7vqXxxdM/UY9_lgkFqlI/AAAAAAAAO98/GU02HOVsQ6s/s1600/image006.jpg> I have modified my Legacy mill extensively. Among the mods was the addition of a MT3 tailstock with ball bearings and a far more reliable leadscrew adjustment. The engagement of the tailstock to the frame rails is trough a pair of 14" long aluminum/UHMW sliders with eight 1/4" lock bolts. The tailstock has about 1" of travel and I have marked the center line and use the tailstock block as a fixed distance above centerline to set the DRO for the Z axis when I change bits. I don't need to remember the Z-height there. I left a label-maker tape with the measurement to .001". The frame has limitations on stifness but the 20 pound tailstock adds to stability. It also doesn't move under load. Reloads of repetitive parts is fast thanks to the leadscrew adjustment. The tailstock locks in length with a 1/2" allen bolt seen on the top of the block. The entire mill has be heavily modified. I've replaced every slide with linear bearings that ride on 1" rails. The rails on all three axis's add a lot of stifness to the frame of the machine. I have machined a complete apron and Y-axis slider as well. The router Y-axis slide is very stiff, moves with one finger and has an elaborate system of travel locks, DRO's and a machined X-axis lead screw block that is considerably more stiff and repeatable than the one supplied. I can replicate parts to within a couple of thousandths. I don't have to leave a setup in place to make another part. I can replicate all the settings very precisely so long as I remember to write them down! The router slides with one finger effort on the Y-axis too so you can actually use the pattern following feature. <https://lh5.googleusercontent.com/-Xqr_207xjyg/Sa8EGCypdkI/AAAAAAAAAa4/adVsaSA-Xfw/s1600/004.JPG> There's almost nothing left of the original Y-axis and Z-axis. The lead screw was welded together from the two pieces and almost all end=paly removed with oli rubbed bronze thrust bearings. <https://lh4.googleusercontent.com/-_ggakW98UD0/Sa8EFfzjXTI/AAAAAAAAAaw/M52Fh5fS89A/s1600/003.JPG> The apron and X-axis DRO sensor. The X-axis lead screw lock is very stable ow and has no end-play slop. <https://lh3.googleusercontent.com/-WtIGHK27Hps/Sa8EHoANzTI/AAAAAAAAAbI/RgRdfgAxv5o/s1600/009.JPG> <https://lh4.googleusercontent.com/-j4fECgbGWt8/Sa8EIaR3tQI/AAAAAAAAAbQ/4Rd22Z2MPfE/s1600/011.JPG> <https://lh4.googleusercontent.com/-esoOiLRt40I/SifwvXIrRKI/AAAAAAAABHE/UUexIgZws6s/s1600/038.JPG> <https://lh3.googleusercontent.com/-tUpDV56QfUs/SifwxxR8vRI/AAAAAAAABHY/RnvbLRNOkSs/s1600/043.JPG>
<https://lh3.googleusercontent.com/-hKOUeI6YmD0/SifwtyBg9sI/AAAAAAAABG4/h9RlJFvjEsY/s1600/035.JPG> I added a dust collection hood. It works pretty well but limits visibility a little. I should have added an LED lamp under there! <https://lh3.googleusercontent.com/-xBX22n3Ek8M/Sifw3iXRmoI/AAAAAAAABIE/0vcD6Vk55J0/s1600/054.JPG> -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
