  1. It's reasonably solid. When using a spindle sander, you don't apply a high level of lateral pressure. The sandpaper should do the work for you. For something as thick as a guitar body, it is better at smoothing edges rather than shaping them. Surface finishing, not stock removal.
  2. I'd say yes. It's worth it for the money, but falls short of what you'd expect for a light trade rated machine.
  3. Negative nancy here; those rods can be a bit dicey at times. The welds usually. It looks like a lot of the join between the adjuster and the adjusting rod disappeared into the pool. Not sure how best to test that before it gets committed to the neck, but worth a once over regardless.
  4. I think you'll find this is clearly a combination bottle opener and hammer.
  5. Not this exactly, however in both guitar work and my work-work, I use a lot of screws as both locators and ways of bringing parts together under compression from the tension in the screw (edit: in this instance of course, screws only locate and hold together, not clamp). A bolt and nut would do much the same thing since that's essentially like a through-hole clamp. In general joinery work I have run the numbers on clamping pressure so many times now that I pretty much run off the top of my head how many large F-clamps (about 1000lbs each) and small F-clamps (200-400lbs depending on model) and
  6. Congratulations on swiping yet another win Andy! I'm floored yet again. I bet this is a fun player, however I've never played a short scale bass with so many features on tap.
  7. In all seriousness though, it's a valid solution but a few tweaks can rattle out possible issues. Reduced clamping pressure needs a good consistent thin film of glue on both surfaces. Pfohl glue rollers are pretty neat, but they waste too much glue on a single component layup! A notched spreader or a hair comb does the trick. If slip is a PITA, lay out your parts dry and shim up the neck part by say 0,5mm or similar. Drill through the areas either side and fit a couple of wood dowels for locating. In the layout shown, downwards pressure on the neck section increases overall pressure in the glu
  8. Clamp police! Hands on the Workmate and show me some ID!
  9. When HDMI-CEC works, it's great. When it doesn't, it's like a The Three Stooges routine.
  10. I was more thinking about the end product in terms of derived values. I'm developing a CNC programme at the moment that takes in specific values and generates the fretboard milling strategy from that. If Grasshopper can also output values in some sort of tabular format for external usage, I can convert that into a variable table for use on the CNC. Simple things like nut width and slot values (or butt end), boolean for zero fret, scale length, number of frets, width at certain placement, etc. I'm sure that most of this will be proof of concept as opposed to something for long term implementati
  11. This looks different to how I would generate a conical section fingerboard, but then again we're probably talking related ways of deriving the same end product. 1+3=4, same as 2+2, etc.
  12. One step at a time I think. I often find that jumping straight into modifications and extensions doesn't allow one to develop a good handle on base capabilities and limitations. It's good to know how something doesn't work, or simply isn't geared for before patching it up with the shiny stuff.
  13. I'm sure that you're already aware that I will absolutely go to town on this kind of stuff, Mike. Rhino is great for product design, and I think this provides plenty of scope for pretty much processing values à la FretFind2D and outputting a 3D modelled representation including fret slots, perhaps even blind slots. The CNC software I use would work better with taking the fingerboard surface as a STEP file for CAM processing, and the fret slot paths as here-to-there points. Once I get some time to fully wrangle with Grasshopper, I should be able to figure out some very powerful hybrid design/ma
  14. I've just ordered some more 462E collets to fit in our HSK63/F toolholders, specifically 3,175mm and 4,0mm to hold 0,5mm endmills. Plenty of scope for cutting inlays in addition to fret slotting. Buying the toolholder for fitting a saw would be a few hundred Euros with the saw on top, and I'm not even sure if the Stewmac saw's diameter is wide enough for the spindle body to clear the workpiece when running parallel to it. Still, cost is cost.
  15. In principle having parametric design capability should be a nice transition from desktop to CNC. I'm going to have a play next week. Busy week ahead of me, but we'll see.
  16. Yeah, but unlike most Norlin era stuff, that had a vibe. Corvuses and all of the other stuff was desparation in the extreme. Terrible stuff. I hope you can bring something positive into the Marauder that Gibson just failed to do
  17. Yeah, that's pretty much how I would imagine Rhino would gain some of Solidworks' parametric design functionality. This certainly would help a number of things both for my work and personal use....I'll going to need to brush up on Grasshopper sooner rather than later, I think! Is there scope for exporting values to CSV variable files? If so, this would open up a lot of potential for outputting milling and fret slotting strategies on the CNC, both single and compound scale with conical radii....maybe a bit more of a proof of concept thing than anything else, however that sort of thing is the be
  18. I've not worked with Grasshopper yet. I presume that it's a step towards procedural modelling by steps similar to Solidworks? In the near future I'm planning on writing up some sort of code for the CNC at work to mill fingerboards by definition. I could do with a few 0,5mm end mills and collets to fit those in an HSK-F63 tool holder.....maybe even a spindle for a fret saw.
  19. I would agree with this as a better way of constructing necks. There's been a constant move towards stiffer and stiffer necks over the last couple of decades at least; mostly down to laminating necks with showy wood, marketing wankateers hawking titanium-this and graphite-that in commercial instruments, etc. I would say that its gotten to the point where these practices are now so normalised that builders see necks without stiff laminates or sixty graphite I-beams as being inferior on some intangible level. Because it FEELS inferior. We're prone to all manner of foibles, misconceptions and sol
  20. As far as I understand it, Jim's V is a typical Norlin 70s Flying V with little to no neck angle. Instead, the neck is set high off the body. Crazy sort of setup, but some people dig that. Shame you have to raise the neck pickup so far off the body plane in that configuration. Are you chewing over this detail, or going your own way?
  21. Good to hear you got your win! I'll have to check that software out myself; does it account for lens distortions as well? That's always the main enemy of scaling from pictures. Funny that you're building a Norlin-era Gibson-inspired instrument. I've always thought that the more rounded end Flying V headstock was the coolest. Essentially how James Hetfield's white "Gibson" looked, but more Jim Martin's chrome pickguard Kahler-loaded 70s V. Those are just too cool for school. This Marauder's headstock looks a little longer than what I have in my mind, but in the ballpark.
  22. It's generally better to scale off larger sizes such as tuner hole spacing or at worst the neck width. Measuring off the tuner hole width is incredibly prone to error. If you knew the headstock angle accurately, you could even infer a size from the spot faced truss rod access footprint. Having a photo of the back of the headstock with tuners installed and the actual tuner body dimensions could help build a value of tuner hole spacing. Those laminates might even be 25mm or 1", however that's difficult to get any reliance from unless you know it as a fact. Also, hole spacing for the truss rod co
  23. Very cool. Run by the numbers.
  24. Trigonometry and general geometric mathematics are a key skill in so many areas of instrument making. It really does create a more solid base to work from, especially when dealing with precise work like this. Like I said, automatic applause bud.
