color some notecard stock black with a sharpie, then spray paint it black to stiffen it more. or laminate several thicknesses of thin black cloth with black resin of some sort (jb weld is kinda blackish), then paint that black. or, put a bunch of staples on the circumference of a dowel, clip away all but one leg of each of the protruding staples, and then paint everything black. or, cnc the pattern on some flattened aluminum can foil with an awl point or a pin or a pen, cut the pattern out with scissors, and paint it black. or, get a CD that you dont want to listen to anymore, and cnc it out of that. and then paint it black. --- On Tue, 2/14/12, gene heskett ghesk...@wdtv.com wrote: From: gene heskett ghesk...@wdtv.com Subject: Re: [Emc-users] Encoder wheel [Was: Need advice on 1/16 end mill] To: emc-users@lists.sourceforge.net Date: Tuesday, February 14, 2012, 6:21 PM On Tuesday, February 14, 2012 09:17:49 PM Erik Christiansen did opine: On 14.02.12 15:20, gene heskett wrote: The encoder wheel itself will be trapped between the spindle bearing lock buts. Gene, have you considered using a piece of thin PCB material for the encoder wheel, since all your sheet Al is toffee? A piece of the brown phenolic stuff would be easier on the tool. Copper is needed on at least one side, if the green fibreglass board is used, because it lets too much light through. (About 34 years ago I was cautious enough to check a piece before making a wheel, and switched to PVC sheet. But I had more room, for a thicker wheel, than you do.)

I forgot to turn one over before I ran lightscribe, and it knew the disk was upside down. And to do that, we would need a working cut-sim to convert our gcode to an image format (png?) lightscribe accepts. My little fishing expedition into that over the last 24 hours seems to have disclosed that none of the trails I followed have led to working code, the closest I got was openscam which I had to build, but then fails to do anything useful, and that the best 'preview' of what I want to do is likely to be obtained by making it out of a cd perhaps a coat of black paint. All this could be satisfied by my proposed additional field in the tooltable that would enable, perhaps as a preview only translation as the code loads, which would turn the backtrace plot into a great preview by utilizing the selected tools diameter as the width of the path to trace, perhaps even using a different color for each tool size, as opposed to the current 1 pixel wide wire frame of the tools center line path. I can see where this is certainly not a run time option for obvious video horsepower needed reasons, not to mention the video memory required. Other than loading time growing by 500x for the preview only render, it would still be cheaper than the worn tooling and materiel cut up only to find there isn't room enough to make it work that way.

Now that might be (the old cd) a usable idea. I probably bin a 50 pack a year of those, old data distro's going obsolete mostly. And that should be cheap enough even if I use a fresh cdr to serve as a test developing tool. I don't recall ever seeing a cd get hot enough to warp either. I can fine tune it 5 thou here, and 5 thou there to optimize the design very easily. Gene - the encoder wheel I use is 3mm Tufnol sheet, painted black. Cheap, flat and easy to machine. I fitted an aluminium hub with a keyway to engage the key on spindle shaft. It's simply sandwiched up against the pulleys with a collar. Steve Blackmore The plastic, except for temporary fitting wouldn't do for permanent as it will be trapped between the spindle preload nut, and it's locking nut in normal operation. That is driven tight with a drift punch in the nut slots. The plastic will 'cold flow', loosening the nut, and that won't be good for things. I've been fooling with that bit of postscript, adjusting it to arrive at a fit, but for slot type opto's its not as good a deal as it would be with reflectance types as it appears to be best done with the opto's arranged in a radial line as opposed to having the slot types in a straight line. The radial line would have the advantage that the quadrature is fairly well fixed in that case as opposed to using a single high frequency track being watched by 2 opto's whose spacing would be trimmed a bit to hit the needed quadrature on the o-scope. Because the postscript puts the index marker inside the main track it would make sense to just increase the depth radially of one slot let the center opto device become the Z signal since it's tracking a smaller circle. The problem then might be better handled by further modifying the gcode I have so instead of an index slot in the rim, just extend one slot inward radially far enough to make the B the Z and vise-versa. The center opto then would need to be pushed sideways a bit to get the actual index edge to be centered in the A+B=(1 or 0 state) in order to get a true index edge. That will be investigated too, but I have got to get off my butt and go burn some sugar, a 2 gram breakfast muffin just put me north of 300, not good at all when ones breath smells like acetone so I'm killing both my feet and my kidneys.

That's when I mounted it in the lathe, and tried cutting it off. I DID get it off last night. There was a gear behind the race, and since it was already damaged, I had a brainfart, and welded a fairly hefty mount to it, took it back to the farmers shop, and mounted a 6dia hydraulic cylinder to the mount. I pressed on the end of the shaft, while applying heat with a rosebud... The Hydraulic pump was straining pretty hard, so I figure I had well over 60 tons on it when the race popped loose. Of course, popped doesn't do justice to what happened when the race came off. I then brought it back to my shop, cleaned up the journal, welded it up, and turned it back to dimension. Handed it back to the owner, took a handful of meds, and passed out. The new parts should be in by 2:00 this afternoon, so I'll see if I'm a Saint, or Satan soon :) Just thinking aloud - you must have removed bearing outers from a hub or such by running a weld around them. When the weld cools and contracts, bearing falls out of housing. Same thing may work for a bearing inner on shaft - make up a loose fitting thick sleeve. Weld between bearing and sleeve and wait till it cools. In theory -- it should expand the bearing... or it might just be a load of bull :) Steve Blackmore I've never tried welding on a race to get it off. I've never had a race that was stuck this badly. I've got all kinds of pullers, many of which I've made. I also have a set of pullers that screw onto a 10lb slide hammer that can persuade even the stubbornest of races to come out. Doing the math, the theoretical limit to the pressure I was applying was a bit more than 140,000 lbs. I figure I wasn't too far from that number, considering how much the pump was whining. When the race let go, it took a fair amount of the surface of the bearing journal with it. The journal under the race was gouged, and heavily cratered, and just as blue as the race itself. Actually, this is the second race this month, that was this badly welded. The planetary gears in my Dad's transfer case ate themselves up, after it's bearing failed. I didn't have to worry about removing that race, because I never put the planetary back in... There was very little of it left, and the input shaft was too badly damaged, The housing looked like a 1920's shootout, and It took the better part of a day to TIG weld all of the holes up (die cast aluminum... Ugh!). Then I welded the input and output shafts together, forcing it to be 1-1 full time.
