Over tube press..
\nSo to get a novel shape from a circular shape is a mathematical problem the parameter of the
\ndiameter of the circle must match the diameter of the oval
\nThere are websites that can calculate this saving us the maths by if you could imagine a cross
\nsection of the circle two lines line A bad line B adding the numbers you want your oval shape to
\nbe A being the longest and B the narrowest measurement we try and get a parameter number
\nequivalent to the circle<\/p>\n

But I find you can use this as a estimate but you have to test and add on a mill to the length or the
\ngirth
\nI mill out the two 20x30x160 bars then put them together and from the center mill out the oval
\nshape to give you your press jig once this is done the two halves are put in a hydraulic press I
\npicked up from eBay for \u20ac70 between your oval jig is the aluminum tube with the same
\nparameter A and B measurement . if it is the correct parameters then you get a perfect oval if not
\nthe curve starts to flatten meaning a crap ovals to fix it I need to cut more of the A Length or the B
\nlength may a mill until the curve becomes expectable<\/p>\n<\/div>\n<\/div><\/div>
