So soon I have a big pile of joined veneers. Attachment : IMG_8866.JPG

Now I need something to go onto the moulds. I’m kinda sorta following Making a Laminated Hollowbody Electric Guitar by Jim English, so I’m laminating 3 layers of 0.6mm veneer and one 1.5mm veneer. The...

And then an awful lot of copy-routing ensued. Attachment : IMG_8857.JPG

This time we took the thickness of the lamination into account, and used a bearing router bit to reduce the first layer of the side mould by around 4mm (oh look, is that a top template I failed to men...

Woosh! Didn’t even touch the sides! Oh no, here they are. Crudely cut lumps of MDF and plywood were copy-routed using the top template I failed to mention earlier. Attachment : 20230129_114408.jpg

Genius!!! I'd always thought you'd be sanding and sanding to get the ridges smoothed out into the carve shape you wanted. Filling it in is so much easier.

Tiny little planes don’t tend to carve out long smooth curves, and paper-thin MDF can tear, so car body filler is used to smooth out the dips. Mark says that’s what all the professionals do. Attach...

It should have been obvious to me that, if each concentric lofting contour was equidistant, the rise would just be in a straight line. But no, so out came the scrapers to try and realise an elegant ar...

The unanswered question at this stage was just how smooth that mould would need to be. We’re not using a huge steaming press, just a little vacuum pump. Will a 4-5mm lamination follow every bump or ju...

Why 3mm layers? Why six of them? Because 5 x 3 plus baseboard gives a height of 15mm and, according to Mr Bagpress (of whom more anon), if Gibson never bent their laminations more than 15mm, then neit...

According to Mr Bagpress (of whom more anon) a concave mould will be more effective than a convex one. This also means that you don’t have to compensate for the thickness of your lamination when build...

Do you then smooth the layers together? I'm guessing so, else you'd end up with a bit of a ridged top? Is it right that you'd have an arch that'd be 12mm-15mm from highest to lowest point? So, if yo...

What about when I think I'm wrong @jamesbisset?

@tv101 You’re always right.

I originally planned to draw the moulds in a 3D program and then get them cut on a CNC machine. The technique for making this sort of complex shape in 3D is called lofting - from pre-computer aeronaut...

@jamesbisset awesome to see you are working on another guitar. Looking forward to see more 🙂

I’m guessing that you posted that design @jamesbisset just to check if we’d spot the deliberate mistake …. Am I right??

I started this project over two years ago (I know) here: I didn’t even know a laminated semi-hollowbody wasn’t an archtop. After all this time building the workshop, accumulating tools, buying parts,...

@wolframmalukker The consensus may have been 10mm a few days ago, I reduced my current build to 7mm yesterday, it still looks thick enough though, thats in mahogany. I was wrong, best stick with yo...

I am more concerned about glue joint area than I am side wall strength. My bridge and fretwire showed up today, so I got to ogle the guitar jewelry a bit this morning. (Schaller 3D-6 in gold) Now, I k...
