CNC Project - Guitar Neck (and the rest if I can get away with it)
Hi Everyone,
Rather than clogging up the excellent Inspiration thread, I'll start a thread to show my progress on making a Fender Jaguar guitar on my CNC machine (or at least as far as that is possible).
So here's the latest video, carving out the main neck body from maple and a following one, which whilst showing me hand making some body templates shows the results of the neck carving on the machine:

The next video in this series will show the fingerboard, but I have many hours of video to edit so won't be until later this week.

Thanks Wal,
Yes, I've had a guitar addiction for many years, with occasional Bass, Mandolin, Keyboards and woeful attempts at drumming. I've seen your playing on your channel and most impressed - makes me miss the band thing (but not the hauling kit about part).
Oh and thanks for the heads up on the 0.5mm cutter - made me recheck my toolpaths and I had to raise the bottom of the pocket heights by 0.5mm to avoid the taper part of the shank from cutting too deeply into the fret slots. I'll use a fretting saw to deepen the slots if needed.

Hehe, same here. 11 basses at last count... :distant: Got into the CNC thing through wanting to build my own - so far I've built a machine to help me build the bigger machine...
Glad to hear that the heads up on the 0.5 cutter may have saved you a bit of headache.
Wal.

One evening I'm going to sit down and watch these all back to back Chris and make some notes!!! I want to make a guitar (or two....) with my machine starting off with something simple like a Tele and then moving onto an Explorer or V.....

Hi Neil,
Funnily enough I have in mind a telecaster myself once the two/three guitars I have on the go are finished. The version I have in mind will have front and back binding, a neck humbucker, phase switch and pre-amp i.e. the Andy Summers model without the $10,000 price tag (if Fender made any more that is). Even though I have a US Standard Tele (circa 95) it doesn't have the tonal variations to get Andy's sound and as I finally nailed the Message in a Bottle sound using an EHX Electric Mistress I need the boost as that flanger pedal cuts the volume when activated.
Ooops apologies gone all guitar nerd on the forum... ;)

Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
I was playing a Tele on the weekend in Reidys in Blackburn which had two humbuckers both coil tapped and loved the playability of it and the different tones you could get....going to look for plans this weekend!

Nice vid as always and good to show mistakes warts and all:applause:. I noticed that you are going to finally put homing switches on using mechanical switches if you mount them as you indicated it will only be a matter of time before you crush them.
It is better to mount them so that the gantry or whatever can ride over them it is easier to use proxy switches mounted at right angles to the direction of travel so that the target runs over the top of the switch.

Thanks Clive and points taken - I'll have to have a think about how to position the switches, but I think I have a few options.
I've also been considering freeing up some workshop space by "vertically" mounting the machine recently to make room for other machinery.

Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Chris, I agree with Clive (though I'm not sure I'm in a good position to comment as I've not got all my limits mounted yet and those that are aren't wired in.......:cower:) proxy's are the way to go and they're no harder to wire than mechanical switches.
Go vertical, nothing to be lost and everything to be gained!!!!! Mine is going vertical (well 85°) when I get the time at work to cut up and weld the frame (the steel is sitting rusting away out in the yard.....) and I can't wait as bending over the sides is a PITA :encouragement:
P.S. if you want some Proxy's then I've some you can have.

Thanks Neil, that's good news - I've always struggled with things like Hall Sensors etc. in the past - I take it they don't need an OpAmp or anything to work?
Thanks for the offer if you have some spare - I'll PM.

Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Morning all,
Part 6 is up and I guess shows the advantages of modelling the neck by cutting the profile in CAD from a virtual block i.e. you get a negative model at the same time:

Thanks Neil,
Looks like there might be a bit of a gap in videos for this project, as I'm stuck whilst waiting for deliveries of both hardware to make sure the body routes and drilling is correct and some acrylic glue for the neck binding.
Luckily there's plenty of other projects to do...

Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Part 7 - no CNC in this video due to binding the necks, but that will resume for the next two videos to come:

Doing great work Washout but let your machine and cutters have there head. This killing me It's like watching a thoroughbred horse being used for Donkey on beach.!! . . . It's cruelty to Machines. :sorrow:
Turn up the feeds watch your cycle times drop, tool ife increase and finish get better.!
-
Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Thanks Steve for the kind words.
Lol Dean - eloquently put sir and point taken :) I must knuckle down at some point and try some deeper/faster test cuts in aluminium and find out where my limits are for adaptive clearing - I have a couple of projects coming up this year that will need them e.g. rudder pedals for the gaming cockpit for one.
-
Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Washout, your welcome. I will look forward to more great videos I like that you use Fushion 360 and that you don't skip through what you do at 100mph. That is handy for me as I am keen on learning Fushion. I can see you put a lot of effort into the videos. I just have to find the time to get going learning Fushion and starting my build!

Hi all,
A couple of videos in the guitar series this week - the first not many people on here will want to view as its setting the machine up for machining, zeroing etc.
https://www.youtube.com/watch?v=8ciU089KZGE
This one shows the actual machining (including a scary tool with a 50mm stick out):
https://www.youtube.com/watch?v=il4-EGwXieY

Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Nice work. At first I thought the adaptive clearing was a bit of a waste on the finish pass as it seemed at first to dance around choosing which pocket to do bits of. But then it made up for that with nice moves when plunging to the next pass - it pulled away from the surface when lowering and then swept into the machining op.
Is that pull away when jogging down part of adaptive clearance or is that another CAM strategy? I only using Cut2D and it stays on the surface when jogging down (well ramping actually). I like your CAM better . . .
-
Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
The adaptive toolpaths were all roughing - I think the one you meant was the neck pocket and the "gutter" that went all the way down? (the first of the 50mm stick out). For some reason I had to do that operation or the partial cut outs at the end would run around that pocket and go 30mm down (i.e. chop out the bit the neck sits on) - hope that made sense.
The "pull aways" on the finishing passes (contour passes in Fusion 360) if they are the moves you refer to, are the lead in and lead out that Fusion puts in by default on 2D contour operations and when cleaning up pocket walls work great.
They are not so good on slots though or when Fusion ignores stock which it shouldn't, although in wood you get away with it - you can see them on the partial cut out slots at the end of the video where the tool plunges and then goes to the edge of the model (would end up in damage in aluminium). There is also a ramping option, which I think I missed off of those cut outs, which I should put in. I haven't quite got the hang of the ramping settings yet and sometimes get warnings or the ramp is way too long - need to experiment more.
In my opinion and whilst I used Cut2D and 3D until I jumped ship, Fusion 360 is so much more powerful and more suited to the work I do (especially the aluminium). It does however have a massive amount of options and is like running through a pre-flight checklist for an F16 (Fusion) as opposed to a Cessna (Vectric)... ;-)

Who sets the feed rate for the adaptive step over you or the software.? If it's you then your too slow I cut aluminium faster than that and with deeper DOC.
I've just cut motor mount pocket in 6082 aluminium with 8mm cutter at 11mm DOC with i-machining which is pretty much same as adaptive stepper over and feedrate was 2217mm/min with Max step over of 1.7mm and that was only on level 3 out of 8 so being nice and easy on machine. Even level 1 was 1335mm/min.?
In wood I'd expect to be cutting 3x that speed at least.!
-
Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Hi Dean
Yeah it was too slow - I think I said so at the end of the first toolpath.
My current workflow with adaptive is to spin up the feeds and speeds in GWizard and then transfer these to Fusion 360. I think what I forgot to do there was tick the HSM check box in GWizard, so it was slower than it should have been. I'll tweak it for the next body (I'm making two guitars, so have a second to do) and use a bit of blown air as my vacuum is a bit asthmatic currently (need a decent shop vac).
FYI - You can manually set a value for "optimal stepover", which is where Fusion tries to get to for the majority of each cutting pass, but ramps sideways into that stepover as part of the "curve". The "optimal" stepover unless you override it is set at 40% of the cutter diameter as a default value e.g. 3.2mm for an 8mm end mill.
Its maybe not as refined as i-Machining, as how aggressive is largely governed by what you get out of GWizard (or equivalent) and I haven't found a way of getting Fusion to optimise stepover or feeds based on a slider like i-machining has (wish it could though).
-
Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Just a quick video this morning (badly shot), of the adaptive toolpath on the guitar body being re-run using the HSM setting from GWizard (setting 2 of 4):
https://www.youtube.com/watch?v=FWxmxiboxns
Settings were: 8mm 1Fl End Mill - 10mm DoC - 22,558 Spindle - 2,945 mm/min Feed Rate - 3.2mm Step-over (optimal)
The Feeds and Speeds are somewhat similar to Jazz's in the post above and ran very nicely, hence me grabbing the camera hastily. I think I could have gone for the setting higher and may do that at some point in a block of scrap.

Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Looks very happy cutting at those speeds!
Wal.

Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Much better your cuttters and machine will thank you for it as well. Bet the Finish is smoother as well.?
One other thing I noticed and not sure if you have control over this or not but will save lot of time is the fact the tool is retracting above surface every time arc ends and tool returns to start while in the pocket. No need for this it's just wasting time and wearing ballscrew away, just retract 0.5. Strange thou because I can see it does this while cleaning corners out but on the large sweep cuts it retracts Z every time.?
-
Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
Hi Dean,
Yes the finish is smoother.
Regarding the Z retracts - I'm not sure why Fusion 360 does this by default for the "sweeps" above 30mm, but there is "keep down" setting you can specify a maximum length for. I'm guessing this is Fusion's way of preserving the end mill's bottom cutting edge(s)?
I'll see if there's a setting for how far it retracts, but one method I know would work, may also risk rapids into uncut stock (a setting in the job height tab). More playing to be done here.
One area Fusion does lack somewhat in is the tool library, as I don't think there is a Feeds & Speeds calculator included (may have missed it). I see on the Fusion forums/patch notes however that this area is getting an overhaul soon, so fingers crossed there.
Whilst I trust in GWizard these days (since they included parameters for customising a generic router to your machine), its a pain to have to deal with a bunch of settings in one package and then transfer those (partially) to Fusion. Its too easy to miss something (e.g. HSM tick box in GWizard)
Especially as Fusion 360 looks to have most of the variables in its tool library, but they don't auto adjust when you change them e.g. change the setpover and watch F & S change to match.
BTW - thanks for the critiques - it really helps me up the learning curve and hopefully others.

Re: CNC Project - Guitar Neck (and the rest if I can get away with it)
I am watching
saw some guitar neck jig on website but for the life of me don't know how it works.
I thought(know nothing about guitars) the headset(or whatever it's called) was tied into the guitar body with a steel rod and this prevented the string tension from bending the neck, and i have heard nut mentioned.
Videos are GR8
