Comments sought on new build: A CNC Router for RC Gliders and Planes

Ok so the MDF moat is off, wasn't too bad to get off in the end.....but in hindsight I'd make sure the MDF was not oily (been hanging around in the machine shop for a couple of months) and put brown parcel tape on it as it doesn't stick to it and comes off cleanly. I'd also put parcel tape on the steel where the moat was going so that the silicone came off easier too. It's nothing that a bit of elbow grease won't sort. I've found the best tool to scrape off the MDF is an indexable lathe tool...not scraped it fully in the below picture



Here you can see the meniscus, the epoxy is about 7mm thick.



Here you can see the difference between the wrong ratio mix of epoxy and the correct...the incorrect is on the right and although you probably can't see it the epoxy is a bit grainy looking and opaque whilst the correctly mixed epoxy is far more translucent and shiny...
