Yeah one of the designs i have looked at when doing this is this: One of the problems with this machine is that it cant "touch off" on the table corners actually. It cant reach there with the mounted palette in the picture. And the movent in X is really limited.. Its a chinese hurco clone. |
| RotarySMP:
That is the trade off. What is more important to you - more travel, or more rigidity? I posted a few pics of my E/G test piece here: http://www.cnczone.com/forums/epoxy-granite/30155-epoxy-granite-machine-bases-polymer-concrete-frame-405.html#post1653506 Mark |

Nice, im guessing if you had gelcoated the inside and cast "wet on wet" into that you would have a somewhat smooth surface. =) Atm im having issues with swedish vendors.. they will sell me 10kgs of resin, but not 100kgs. And on top of that i can find crushed aggregate but not smooth pebbles - apparently all pebbles and such is imported and are of danish or czech origin. Need to find a different source for slow curing resin, apparently one without solvents so its not flagged as hazardous. |
| RotarySMP:
The surfaces in contact with the tape are very smooth. I think a gelcoat is unnessary for what we are doing. The only defects in surface finish are just from lack of preparation whete I didnt bother getting the way smooth, or lack of vibration. I also dont know why people plan to paint E/G. A little carbon in the mix and it looks great. If you want to make a pebble path in your garden, the pebbles are imported from flat muddy Denmark into granite Sweden? Hope no Norwegians are ready this 😁 Mark |
| NeoTech:
Well they dont sell Smooth pebbles for path, i dont think ive actually ever seen it even.. you can get coarse pea pebbles in 2-5mm that will hurt your feet tho .=) |
