Hi Tim. I plan to make a TH-cam video covering how I design my interpretation of Brian May's Red Special in CAD later in the year. I have never scanned any guitars, especially not a BMG Special which is too different from Brian's original Red Special on which to base an authentic replica. I work out basic shapes and sizes from first principles, known published dimensions and reasoned judgements. This leaves room for interpretation and also personal customisation. Check out my design sketches and insights on how I do this on my website: dsgb.net/projects/redspecial/design/ dsgb.net/faqs/plans/
Yes. Additionally, the CutCNC machine control software and VFC control unit have functionality to allow machine speed to be controlled automatically via the GCode. However, I have no use case for this functionality so have never explored it.
No. Please read my rationale here: dsgb.net/faqs/plans/ Selling CAD and CNC files is not something that is done in the design and manufacturing sector to the best of my knowledge and I follow the same philosophy. If you contract a company to make something for you, you pay an hourly rate for the design and development work and the files generally remain the intellectual property of the originator. If these are passed on to the client, the client generally won't sell them or publish them to protect their work and the considerable number of man hours input to research, design and development. The intention of my website and video content is to show enthusiasts and hobbyists how to design and make an authentic Brian May Red Special replica, not unwittingly make life easy for people with commercial interests. To be fair to me, I have already published a considerable amount more than anybody else and more than I probably should. Consider this: if I sold my plans or CAD files to a random person, what stops them uploading said plans to a file sharing website where anybody can then access them for free and exploit all my hard work? 👍🏻😀
pretty neat, I was wondering if a 4th axis would be required for the back of neck carve, just looks like it needs a couple passes with a spokeshave and its all good
I originally bought a Stepcraft 4th axis unit but as I built up more experience with TurboCAD, MeshCAM toolpaths and machining with my system, I eventually worked up a cutting sequence which didn't require it. I never uses it and subsequently sold it on eBay. I don't even use a spokeshave. Just a few minutes with 180 grit abrasive paper to smooth the neck after machining.
Yes. The holes are angled at five degrees to the cutting plane therefore you can't mill the full cylindrical hole from either side. It might be possible to get each hole 80-90% correct this way on a double sided cut with precise registration alignment but I considered that this would increase cutting time and yield an unsatisfactory outcome. The first guitar neck I had made using a commercial CNC service in the U.K. cost hundreds of pounds and the tuner holes were oval, irregular and unsatisfactory. I resolved that if that was the best a professional CNC operator could do, it wasn't worth exploring it.
Excelent job!
Thanks. I hope it was interesting or useful. 👍🏻😀
GENIAL me encanta tus videos , estoy viendo como hacer mi red special y con tus videos m guio
Gracias por sus amables comentarios. Me alegro que mis videos te sean de utilidad.
Great set of videos. Question. How do you get the accurate parameters for the CNC machine. Do you laser scan an existing BMG RS? Thank you.

Is the control unit just allowing you to manually control the spindle speed with a VFD?
Yes. Additionally, the CutCNC machine control software and VFC control unit have functionality to allow machine speed to be controlled automatically via the GCode. However, I have no use case for this functionality so have never explored it.
Where did you get the cnc files? Can’t find them anywhere ❤
I do all CAD design and CNC toolpath development work myself. Nothing is downloaded from the internet. That's why you can't find them anywhere. 😀
@@dsgb do you still have the files?
I retain all my files, yes. However, I don't publish them or give them away though.
@@dsgb completely understand but do you sell them?
No. Please read my rationale here:

Is the machine head incapable of doing the manual operations for holes for some reason?
Yes. The holes are angled at five degrees to the cutting plane therefore you can't mill the full cylindrical hole from either side. It might be possible to get each hole 80-90% correct this way on a double sided cut with precise registration alignment but I considered that this would increase cutting time and yield an unsatisfactory outcome.

@@dsgb thx for the info!
