How do I cut the profile on a 1 3/4” thick guitar body? What bits do I need? Thank you, Total Newbie.

I use a 1/2" Compression bit, works real good for me. Pat

Thanks for the response, Pat. Is that 1/2” long compression bit or perhaps one with a 1/2” shank? I’ve never understood how my 1/4” Makita could use a bit with a 1/2” shank. Mark

Thanks for sending the links, always good to see how others approach a project. Mark

Sorry, I thought you had a spindle, yes it is a 1/2" shank bit, although I don’t see why a 1/4" bit wouldn’t work even with the extra long length of cut using conservative speeds and feeds as well as shallow depth of cuts Pat

Pat, Thanks for clearing that up, I’ve wondered how to use 1/2" shank bits for CNC–guess you need a spindle router. I will be cutting 1 3/4" hardwood; how long should the up cut/down cut/compression bit be? I’ve seen a bit at Bits and Bits that had a cutting length of 2". Would that be surdy enough…

Hey Mark, milling bits are being deflected by the load. Therefore it is a rule to always use the bit with the shortest cutting part possible (and the shortest shank required also). A long bit for deep pockets is sometimes required, but should not be used as general purpose bit. People who have done…

Mark, You can ask a dozen people for feeds and speeds and get a dozen different answers, if I was cutting what you are cutting I would use an up cut bit, 2 flute, about 50 IPM at 18,000 RPM with a depth of cut of .125 or so per pass, being you are using a 1/4" bit I would not recommend a compressio…

Hey Mark, in the video I linked above , which shows how to cut out a Jazz Bass solid body and then how to make a Jazz Bass neck with a CNC, they show all the bits used and they give the necessary cutting parameters: [Felder_Jazz_Bass__Mark_on_cutting_parameters] If you read the “more” link you al…

Hey Mark, hey Pat, hey all, [image] PezWoodworks: if I was cutting what you are cutting I would use an up cut bit, 2 flute, about 50 IPM at 18,000 RPM with a depth of cut of .125 or so per pass, being you are using a 1/4" bit I would not recommend a compression bit in order to aid in chip remov…
