I had a hard time decking it because of a combination of feed rates and high speed still endmills sucking. I also didn’t know that MDF was abrasive (ended up burning the top before I was finished lol). So I was starting to doubt it until I ended up decking the hole thing with a 2 flute 1/8″ carbide endmill and it tore it up! Then I have (since posting) received a carbide 1/4″ endmill and I got all mt clamp holes cut. It powered through 25 3/8″ x 5/8″ holes in less than 5 minutes, and it would’ve been 3 minutes had I not been nervous and started at 100% feedrate right away.
Gonna try 1/8″ aluminum tomorrow, probably just a simple keychain or something. For the time being until I get a mister or something I’m just gonna use WD-40 for some form of a lubrication.
