Not a bad idea, but how many tons needed for the bottle jack? I assume the dies would be good hardened steel. Can that be edm'd? Using what for electrode material? Probably not with the sharpness of detail in the text though, because the electrode would also go away. OTOH, my experience with edm is limited to broken tap removal, a PIMA but it did work, very slowly as I had no way to circulate clean K2 into the blind holes for debris flushing even if I was using 1/16" OD tubing to go down a 6-32 hole. I bent it about 10 thou & ran the spindle at about 50 rpm and got faster cutting than with 1/16 solid brass rod. That just sharpened itself to a bullet profile and took cleaning out & new k2 about 3x as often. In which case I'd still need the code. :( ISTR seeing inkscape can do the circular text bit, even OOw might be able to, but how to translate that into gcode? I don't recall seeing an inkscape to gcode utility. TTT maybe, but it doesn't do 3d if you want to use a pretty TT font, where the wider strokes of the font would get a deeper cut as opposed to just following the outlines with two cuts. That I've tried, results sucked. POtrace can follow a bitmap, but again not in 3d. Ideas for a post proc for TTT output to make it do one stroke at variable depth so as to trace the center up to the width of the cutter? Being able to use a nice cursive calligraphic font in 3D from www.goldenweb.it would be a huge plus. They have some truly beautiful fonts there which are free to download. The old man mutters again. Pursuant to having a fixed home to set limits from, I bought two micro-switches yesterday to put on the lathe, but still trying to figure out how to put one on the Z that wouldn't get fouled by swarf. X will be a problem too unless I can hide it under the cover for the screw but that will put it in the wrong place, I want them both to make as it backs away from the work. That's so I can home it with work already chucked. I thought of fixing a wire to the crossfeed, extending out thru a small hole in the motor mount & letting a 90 degree bend in the end of the wire pull the switch but there isn't enough plate beyond the motor. So I almost have to mount that on the front bearing extension so the cross feed hits it a few thou short of the end of back away travel. That area is also loaded with swarf and would need a sheet brass, or ALU cover fabricated. I need a small brake but TSC's cheapest is 2 feet wide and $300. Comments welcome, pix of what you folks have done even better. To be continued... Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
