The current 1/4" bit capacity of either the Makita router or a 65mm spindle presents a dilemma for me… which is cutting the outer contour on a 1-3/4" thick guitar body at full depth and the limited or unavailability of bits without a sufficient length of cut to do a full depth finishing pass.
I can get an extra long bit with a 2" LOC intended for milling metal, but I can’t find anything intended for routing wood. I expect the cutting geometry is different on cutters intended for metal versus wood.
Of course metal-purposed cutters will freely cut wood, so that could be an option though I anticipate less than optimal results.
Curious if others have been confronted with something similar, any experience to share in this regard? Thx…
The link I posted is for an end mill with 3" long flutes and 6" total. That should meet your needs of 1 3/4" cut depth. Though you will likely get some chatter with something that long cutting that deep.
This may not be desired but how about just doing your max DOC finish pass, then trimming on the band say and using a pattern (compression) bit. that way its built in holding tabs and you wont get as much chatter.
