Beveled Box, Guilloche Inlay, Wooden Hinge

Postby Tailmaker » Sat Aug 04, 2018 7:23 pm

I had a glued up maple box sitting on my shelf for years from a finger joint experiment but the 3/4" wall was way too thick for its size and not usable. Now I pulled it out to reduce the wall thickness to 3/8" on the CNC. That allowed me also to give all edges a generous bevel and make the box look less "boxy". The lid is embellished with a v-carved guilloche pattern inlay and monogram and hinged with maple barrels on a 2mm steel rod. The guilloche pattern is generated with an external program and imported into Aspire for the v-carve inlay method and cut from padauk for good contrast with the maple lid.

Some pictures along the process in the following posts:

Shaping the outside of the box (held in place on the disposable board with vacuum). This is my longest reach 6" ballnose bit but it barely made it:

Shaping the inside:

Inlay male and female are cut. It did not carve that cleanly, maybe my bit was dull or cut too fast. But it did not affect the result much:

Inlay glued and sanded, hinge groove prepared:

Cutting the hinge barrels (end grain):

Barrels threaded on hinge pin with release film, glued and clamped:

Hinge is glued in place. After this the pins are pulled out, lid lifted off, release film removed and protruding tabs sawed off.

All surfaces including hinge are now sanded flush, finished with unpigmented oil stain, waxed and hinge pin installed.

And finished outside. It has some minor flaws from the original glue joints but I think it looks good enough for a gift.

I like that! Especially the hinge treatment.

BEAUTIFUL G. !! :D
Haven't tried radiusing a FingerMaker corner yet, but might now:)
Well done!

Scott, if you try this, make the fingers full or almost full length. Shortened fingers will just be cut off by the bevel radius.
I think I will also try another one with full fingers and in walnut. The "invisible hinge" crevices are still very visible in maple but might almost vanish in dark wood.

If there is interest I could sometimes post a more detailed description or tutorial of the hinge geometry and methods with tool paths. It took me a few failed projects to get this right.

I think a tutorial on the hinges would be great and something I am sure would appeal to a lot of members. A generous offer and I hope you get the time to share the knowledge

Very nice job. The hinge system is very smart.
Best regards

Thanks for the tip G.......Will do. :)
What glue for the for the VInlay(wondering if you ever did play with the translucent TB)?
Carnauba finish?
Beautiful chips by the way:)

I did use the translucent glue for another inlay project and it works well but I ran out and used TB1 for this one. If the vcarve job is done right it should almost not matter which glue is used because the glue gap is so small and the glue is invisible. However, in real life the end of the male part ridges may not be super sharp or chipped off and ideally the glue should be dyed in the color of the inlay to hide such minor imperfections. I did not do that, though and just used the TB1 out of the bottle.

The finish itself is 2 rubs of Minwax 70000444 natural (unpigmented) oil stain. Works pretty much like Danish Oil but is thinner and dries faster (also cheaper). I only used the Carnauba wax to give the surface some sheen and better feel after steel wool rub. One thing that bothers me with maple is that the end grain and all beveled surfaces becomes significantly darker after finishing but that is just the way it is.

The crescent shaped chips are kind of typical for the big ballnose bit since the entire ballnose radius cuts. However, one disadvantage I noticed doing serious wood removal with a big ballnose it tends to chatter much more than an endmill, especially when sticking out 5" from the collet. It takes a bit of ear adjustment of feed rate and spindle speed to minimize that. Once it starts chattering, the surface will be ruined in no time.

Thanks again G***!
scott

Oh...one thing that works pretty good for me if I don't want the contrast, is I'll go 1 or 2 grits finer on the end grain.
For instance these blocks are sugar maple, and all faces went 400G, and then end grain was 600G.
Even though they went through my hot soak Linseed/beeswax, you can see that the tops here(endgrain) are pretty close to the other faces.
Doesn't always work, but usually.
