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

Quick question to those who cut balsa (and lite ply)....I use these cutters...http://www.shop-apt.co.uk/single-1-f...us-metals.html

Which cut it OK, however they do lift the balsa and on soft balsa tend to rip it when cutting across the grain. What cutters do you use? I was thinking of trying some down cutters but was wondering if there were better ones out there?

Hi Neil,

I use 3mm 2 flute TCT router bits but have a similar problem on balsa. I also thought about down cutters but never tried it in the end and where possible I use lite ply instead and have larger cutouts to keep the weight down. Lite play tends to leave a thin layer of whiskers which is easily removed by running around with a scalpel to leave a clean finish.

Thanks
