I agree, legacy was then aimed at the hobby person who usually can't afford a large price tag if they were better and more expensive I know I wouldn't have one better to be able to do most things a little rougher than not at all and even the new evolution I don't think I could afford it or the very high shipping I would have to pay.

Others don't always make that point. A lot of people--in fact most--balk at paying the 1.4K that the 900 used cost. I wonder what a "dream legacy" would cost.

Nearly all of my wood working machines have been modified for accuracy and include DRO's. I've made an elaborate router table/overhead sliding table router and several other tools. I suppose that amount of accuracy is an overkill with woodworking but I prefer it. It also allows for faster easier setups. I can replicate any setup in seconds if I've recorded the settings. The original Legacy mill was horribly inaccurate by my standards. The so-called bearings were just inadequate for the machine. They deflected and bound under load. The fram was too light and flexed with the applied loads from the bound bearings as well. The bearing rails add considerable strength to the X-axis. The router carriage is a complete fabrication. The frame is all 1/2" or 5/*" plate aluminum held together with 1/4" and 5/16" bolts. Its really solid. All of it slides effortlessly on those bearings. I made the mill work like Legacy should have but couldn't because it would have made the cost prohibitive. About eight years ago I sent them a detailed description of what I had done and then eventually came out with a new "Evolution" machine that has all these features. I should mention that I also roll-pinned all of the gears sets that came with the machine. The gears were held together with central delrin bushings. When loaded they would start to deflect or even turn independently. Just drill through both gears and insert roll-pins and they be locked together with no slop.

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". <https://lh3.googleusercontent.com/-kyY7vqXxxdM/UY9_lgkFqlI/AAAAAAAAO98/GU02 HOVsQ6s/s1600/image006.jpg> <https://lh3.googleusercontent.com/-kyY7vqXxxdM/UY9_lgkFqlI/AAAAAAAAO98/GU02 HOVsQ6s/s1600/image006.jpg> 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. <https://lh3.googleusercontent.com/-kyY7vqXxxdM/UY9_lgkFqlI/AAAAAAAAO98/GU02 HOVsQ6s/s1600/image006.jpg> <https://lh3.googleusercontent.com/-kyY7vqXxxdM/UY9_lgkFqlI/AAAAAAAAO98/GU02 HOVsQ6s/s1600/image006.jpg> 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://lh3.googleusercontent.com/-kyY7vqXxxdM/UY9_lgkFqlI/AAAAAAAAO98/GU02 HOVsQ6s/s1600/image006.jpg> <https://lh3.googleusercontent.com/-kyY7vqXxxdM/UY9_lgkFqlI/AAAAAAAAO98/GU02 HOVsQ6s/s1600/image006.jpg> <https://lh3.googleusercontent.com/-kyY7vqXxxdM/UY9_lgkFqlI/AAAAAAAAO98/GU02 HOVsQ6s/s1600/image006.jpg> <https://lh3.googleusercontent.com/-kyY7vqXxxdM/UY9_lgkFqlI/AAAAAAAAO98/GU02 HOVsQ6s/s1600/image006.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. The apron and X-axis DRO sensor. The X-axis lead screw lock is very stable ow and has no end-play slop. I added a dust collection hood. It works pretty well but limits visibility a little. I should have added an LED lamp under there! -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
