Awesome thread, thanks, and thanks again.
Regarding the epoxy self leveling mounts for the linear rail, I would be very interested to learn about how the epoxy mounts stood up over time in respect to hardness?
I am a bit worried that it may not be hard enough to put up with the loads over an extended time (in a production shop router), as the bearing area under the linear rails is not huge. So my question is really hoping that you can tell me that it is all still good after the machine has been in service for a good while?
I am thinking about this in terms of (on my own coming build) whether to add additives to the epoxy to increase hardness, or alternatively, I may just use the epoxy for producing a level datum surface but then install a machined flat (i.e. 100mm x 10mm milled m/steel) on top of the hardened epoxy. I should mention that my build is planned as a production shop router at 2.5m x 2.5m bed, 30mm rails, 5kw spindle, gantry assembly approx 120kg.
Any feedback on the epoxy hardness issue would be very much appreciated.
Regards, Jono
