Setting a mill parallel cut a set of four 2x4 blocks all exactly the same length cut them to the length of the distance between the top of the inner rails to the top of the outer rails place them on the inner rails up against the outer rails
Then you can feel the top of the block and the top face of the rail to get all 4 ends level. Nice and easy no measuring for fine adjustments use feeler gauges . i have even laid a metal strait edge across the rails over the blocks so i have both hands free to adjust the rails. When turning material round with the bottoming bit make sure it is off centre by at least 1/8 inch and turn the material so that it turns up under the cutter not over down to the cutter and the material needs to rotate much faster than the saddle is travelling along the rails Slow feed faster rotating Bill From: legacy-ornamental-mills@googlegroups.com [mailto:legacy-ornamental-mills@googlegroups.com] On Behalf Of Jim Riggen Sent: Wednesday, 15 February 2017 9:29 AM To: Legacy Ornamental Mills Cc: curtgeo...@wowway.com Subject: Re: Accurate setup Curist, Thank you for the info. I checked each corner and found the distance from the top of the lower rails to the top of the upper rails to be all different. So, I did what you suggested with the adjustable square and tried again. The results are quite a bit better but not what I think they should be. Measuring the cylinder at each end (it is 16" long)shows a taper. At the tail end the diameter is 2.908' and at the head end the diameter is 2.917'. I checked each corner again, this time with calipers. The value at each corner is as follows: rear tail - 1.351; front tail - 1.341; rear head - 1.371; front head - 1.362. Am I expecting too much or not? Do you and all the other users go through this process each time you change the height or tilt of the lower rails? Also, I guess I should ignore the little step shaped openings in each of the legs that supposedly allow one to "accurately" set the rail height.

How small is the Error? and in what way?? do you mean that the cylinder/spindle tappers is some way form one side to the other? or there is tare out and the shape is not round? There is a small learning curve that needs to be understood when using the Legacy, ( Most people just call it the trial and error method.) I would start with making sure all four corners are on the same plane, I would use an adjustable square and check and make sure the rails are the same height form each-other . (this is from the top rail the the lower one.) or if making a tapper the two ends are at least the same as each-other. When cutting make sure your router is 1/4"-1/2" off-set from the center-line of the work. its not as critical but there is an article called clime milling VS undercutting. (See attachment.) You may also need to make sure that there is no slop in your slides, your machine must move freely but if your slides have some play in them, then the slop/play can be transferred into your work. If there is any movement, (UP/Down, or side to side) you will need to adjust your slides to remove any play. I need to run now. PLAY with your machine and get to know it better. I rec emend to use green wood or free wood for play, (the fire wood pile or scrap wood) Dont spend much money for wood that most likely will not turn out when trying new things. I also like to tell everyone, Lastly one last note. Never tell anyone what you are making until its done... That way the 4 poster bed, that you planed to make, that turned into a pencil box, will not look so bad. ;-) Good luck. And have a GREAT DAY.

I made a round piece of wood! One problem though. I used a #2704 bit hoping to get a smooth cylinder. Alas, I did not. I think the router and wood are not perpendicular. The error is quite small.
