Very nice presentation here. I see some great guitars coming out of your shop!
Try making a body without the chamber behind the bridge. Makes a very favorable difference.
thanks for all your comments!
I read about not-chambering the bottom and wanna try it to compare, although this Jatoba wood is freaking heavy so couldn't *not* do it
Forces of nature keep playing against this build.
Forces of mankind and machine keep playing for it.
Would this be a problem for the glue?
Stay tuned for our next episode of "yet another Thinline", coming up next on The Tele Home Depot channel
are we flat?
I hope so!
This is the 3D model I'm building: hopefully I'll get to CNC the neck this week.
Body is out of the CNC.
I'm really digging using this machine. I've learnt a lot in the process and if you all want – I know you do, I do! – I'll try to keep posting how I got to this stage.
Nice job , whats the final weight ?
Something around 2,5kg , or 5 pounds
Here is my shellac mix. I've never used it before and it seems really easy. I just used a rag and hand rubbed it along and across the grain.
Applied a couple of coats, an hour apart. Also tested on some scrap and could easily apply more thin coats 15 minutes apart, maybe 4 or 5. The grain really pops out after even the first one. You can feel it and see it.
It doesn't show in the pics but once the grain lifted the tool path and bit rotation marks became visible.
On those scraps, I tested sanding a little and the result is something flat to the touch, but for a wood like this, similar to mahogany this is NOT like using a proper grain filler. I'll keep adding coats on the guitar to see if I can build up enough of a sealing layer.
This last shot is just for my documentarian spirit. MDF version along real wood.... and yes, it seems there's a pinecaster on the way too...
Wow this thing is looking great! Came over here after your comment on my thread. Excellent work, my friend.
Looking real good!
When you get a chance, put up some details of the CNC machine, the cutting speeds and depths, the cutting tool size and type.
What CAD and CAM software are you using?
I like your design work on the f-hole. Size and balance of its shape are perfect. As are the top stripes.
Thanks! I wanted to achieve balance and tradition with a twist! I can share the design file if people want it.
Files (thanks T. Downs) are prepared through Adobe Illustrator, exported as PDF. Then onto an old version of Enroute Software for CAM, into our MultiCam Classic. We are also experimenting with RhinoCam for carving the neck, but that is not done yet.
I'll gather tool and speed info and post it soon. Already have sort of like an step-by-step pdf so it should be easy to share.
After 2 shellac coats came sanding, light touch with 120 grit on a sanding block.
Mate look is sawdust, but the feel to touch is already smooth, even though I can still see grain grooves.
This shot shows how it looks before (left) and after (right).
Top and back are easy, sides, not so much
Whenever the grain was cut perpendicular the feel is very very rough. I wish I could drum sand it, but I can't, so elbow grease it is...
This was the final shot for the day, after cleaning dust and applying another shellac coat
Two interesting things:
- You can see how dark shellac can get compared to untreated wood
- Applying this third coat you can start feeling when the alcohol evaporates and shellac becomes sticky. I could lay a thicker coat and quickly *spread it around* whereas the first two coats were more of a *rub it into* the grain.
If I look closer, smaller grain grooves are starting to get filled and flush to the top, and general feel over the top is a smoother flat surface.
Gloss is starting to build although haven wet sanded yet
Front cavity is too deep but I can easily fix that.
Wow, nice job so far! Albeit, I'll probably never end up using a CNC, it's still great to see the things people can make. I find myself attracted to the feel of using hand tools.
At first, I wasn't too sure of the wide maple strip on top but it looks sharp!
