If I could get a Lugana where I live I would have bought one. I have a SegMag Beta but it might be a nightmare with customs getting it to you from Portugal. I’ll report on the machine when I get it running. It was delivered but the mfr will be here next week to set it up. (what a convinience)

Fantastic!!!! Yes a computer in the shop seems a bit odd at first. Nice that you have some younger mentors for CAM. I’m learning CAM in Solidworks now…actually procrastinating in learning. Yet I know I will do this. My CNC (Tillie is her name!) was delivered this week but yet to me hooked up by the mfr. I’ll post when I have it running.

I found a good resource for chip rates and speed rates for end mills of 1/8, 1/4, and 1/2″ diameters. They also have a speed rate calculator that includes hard woods. For a 1/4″ end mill running at 15,000 rpm, the speed rate is between 270 and 300 inches per minute. Seems very scary fast to me. I’ll try this on pine first!!! For an 1/8″ end mill the rate is between 90 and 150. The larger the tool the higher the speed rate. So the 100 inches per minute was a good guide value and just go slower for the end mills that are smaller than 1/8″.

That’s really cool. I have items I want to turn into designs that would be tricky to draw. I’m looking at the cost. Are they around $500?

Thanks Paul. I’m relearning how to machine as I haven’t done this in five years. I’ve forgotten so much. I used to have a set speed like you do and alter it with the machine stress. I’ve found a calculator on precisebits.com that has inputs I’m not really familiar with like chip rate and runout, but I think I should learn what these mean. Again thanks for the input. It really helps.

The company that is making my CNC router uses Fusion 360. Of course he pays for it yearly. He sells Vcarve so I know he thinks it to be a good software. I’m tempted to buy it as it is a one time purchase. He also recommends Rhino and I know there are many in the forum that use Rhino. I think I’m the only one that uses SOLIDWORKS so the comment about help is very valid. I have found a great teacher on YouTube Professor Cameron. I feel like I’m really learning now not just going from one video to another trying to find answers. Yes you would have to have a family member that is a student or a teacher to keep a student or educational license. It’s a bit of a pain and my paid for version still says I’m a student which is really annoying. The bottom line I think is to pick one you think will be in your budget and learn it. Learning another is tough.

Thanks Ian. I am hoping others will like it too. Yes I am currently a Solidworks user and the price keeps going up. I recently considered yet again to use Fusion 360 but have issues with them storing my files. Plus the software does assemblies radically different.
I really love Solidworks and it has CAM integrated. Solidworks CAM is intuitive and will give a good start of the tasks with your custom tool crib. I’ve used SprutCAM in the past and it was not as easy to use. I have a rep meeting for Rhino next week.

Hi James and thanks for your interest and kind words. I’d love to have you play one of mine! Would be an honor.
I am attaching a few more images that show the neck and body. It is not a neck through as the pickups are so huge! I use sidewinders for this build. The neck plate is 1.8″ x 2″ (very tiny) with 0.7″ of wood for both the front of the body and the neck. I plan on using inserts with bolts. The neck plate is under the body back. It isn’t drawn only a recess for the neck plate is shown.
I have a full body back cover which is not common. I’m thinking I might need to add more to the back for the neck attachment. My initial build was a glued neck and it is very stable. But for ease of manufacturing, I want to use a bolt on neck.
Yes the truss rod nut is located on the body side instead of the headstock because my neck is on the thinner side (0.65″).
The bass will be probably under 6 pounds or 3 kg. I use a balancing device called the “Comfort Rod” that is integrated into the build to eliminate neck dive. This is how I can make a body so small. This is the first design with many more to come! Let me know what you think. I could do a session on the loothalong showing the rendering.

I agree that it would be hard not to get infatuated with using it. I’d be looking around the shop for things to scan and then make!!! Oh wait, guitars right. That’s the focus.
I think for that price you could consider scanning things for a fee. I have these drawer pulls that I love and want to use the design for a tailpiece. It would probably be easier to scan it. Any interest? I could mail it to you.

Thanks for the information. I have a lot to learn as I am a self taught machinist. Yes if you can find an additional resource let me know. I’m not so much interested in going fast but machining a neck takes a long time at the speeds I used to use. I’m actually a bit timid…ok I’m really scared to go too fast!
My machine is being built at SegMag in Portugal. They are really solid. I’ll ask Joao the owner his opinion too on speed rates. I’m sure he will know a little 🙂 I was really fortunate to find a CNC manufacturer within 1 1/2 hours of my house. They even make their own control boards and have a company machine software that is an improvement to MACH3. It was a little more than I was expecting to pay. Yet experiencing using a kit machine was really painful and I wasted a lot of materials and time. I’ll be taking a video of my machine in process of being built and then the set up in my workshop. They are making a flip feature to allow for two sided machining without moving the blank off of the machine.
I’ll check out the Fusion teacher. Thanks again.

Hi Dan. I had the same experience with Fusion 360. I couldn’t import my files and yes all cloud based. I was hoping to use it, but think I won’t. I was mainly looking for a less expensive solution than Solidworks. I started using Solidworks with my daughter’s school account and finally bought it. The student version is $100 a year. It has all that I need in that the CAM software is built in. I’m just starting to use the CAM so can’t be 100% sure that it will be able to give me a good program for a neck. Maybe try the student version like I did. Or if a family member is a teacher that will work also.
