Purple heart and huon pine box
Here is another one of my efforts that missed the Xmas 2106 deadline. Made for my youngest daughter to her specs. External dimensions 300 x 200 x 120
The sides are 10mm purple heart timber from Brazil. My wife found it while I was wandering around Trend Timbers up Windsor way, when we were last in Sydney for my niece's wedding. Some people that have seen it think it is dyed timber. Philistines, troglodytes, peasants
The lid is huon pine, floating in a 4mm rebate in the box sides to allow for expansion and contraction, with 1mm deep 90 deg V grooves for the rays, done by mounting a trimmer router in a sled and clamping the sled to the workpiece.
I still haven' perfected a way to cut the lid from the box. This was my latest effort with a Laguna Resaw King blade. Operator error shown in pics below!
The tray is made of a rare piece of 8mm northern silky oak, with all the 5mm dividers locked in place in blind rebates.
The box and tray are finished with Kunos #244 oil. It was important to get all the oil out of the grooves on the lid before it sets, or you end up with a grimy mess in the grooves.
The lining is red felt, and I was surprised to see how well it went with the purple. Had to be felt, by demand, not pigskin, as no animals were to be hurt in the making of this box. Bloody kids!
The following pics are taken prior to the finish coat:

Very nicely done indeed !
Do any finishes maintain the purple colour, or does it always fade back to brown on exposure to UV? Never tried purpleheart, but might have to pick some up next time I'm at Trend Timbers.
Cheers

My limited experience with Purple Heart is that when sanded it goes brown / grey, and exposure to UV restores the purple colour. That box was sitting on an outdoor patio table for a few weeks, not in direct sunlight, to get it to darken as much as possible before adding the oil finish.
Be interesting to see how the colour goes over time
Information from The Wood Database website says:
Color/Appearance: When freshly cut the heartwood of Purpleheart is a dull grayish/purplish brown. Upon exposure the wood becomes a deeper eggplant purple. With further age and exposure to UV light, the wood becomes a dark brown with a hint of purple. This color-shift can be slowed and minimized by using a UV inhibiting finish on the wood. For more information, see the article Preventing Color Changes in Exotic Woods.regards,

Excellent work there. Beautiful workmanship.
How did you clean up the bandsaw marks? I read about somebody using their jointer to do this. I have never considered it, but it should work in theory.
cheers,

Have some 1m long x 600 wide continuous sandpaper on order from The SandPaper Man, one of this Forum's sponsors. That will make it a lot easier, in one long piece on the glass 300 x 800. The box tends to tear into the joins of the adjacent sheets on the glass, even though they have been tamped down flat with a veneer rollerregards,

Hi Dengue, Nice work. I clean up the saw cuts from seperating the lid, by running it through the drum sander then, like you, sand the remaining marks out on a sandpaper board. I get a length of floor sanding paper and glue it to a sheet of 19mm ply, about 300 x 400mm, with aquadhere. I think it is a bit safer than glass. I find the drum sander gets the joint close, but not close enough. Still takes time to get a good job.

Thanks for the nice comment Alex.
Have you tried separating the lid cutting part way through with the table saw?regards,

I have recently ground a box and lid, put them each on a granite plate and found no wobble, but put them together prior to fitting the hinges and found the two planes are not coplanar - there is a gap on one side of the box/lid joinregards,

Dengue, before I use the sanding board, I will run a pencil line aound the edge to be sanded. That shoows me where it is not being sanded flat on the board. Drum sanders are not infallable, in spite of what the manufacturers say.

Nice job on the box! . . . although I'm not too keen on the red felt - but the customer is always right eh!
I just split a batch of 4 document boxes on the bandsaw last night for the first time and was pleasantly surprised with the results. Had assumed I was going to get some deep wobble marks from the brand new carbide-tip blade so I allowed 3mm extra between my keys to separate the lid, but even after removing the deepest cut marks, I had still only wasted 2mm - so now my key spacings don't balance . I used a sheet of the same paper you ordered but glued it to some melamine-chipboard instead which is as flat and stiff as you're ever going to need it. After sanding on the board, all four box lids sit perfectly flat on the bases - very happy with the result
I also used the sanding block to flatten the keys off after removing the bulk on the disc-sander - best result I've had on those suckers yet!
Making that block was one of the easiest but handiest things I've made for the shed - get's used a lot!
Only glitch I've had is the little hump near the middle that developed after a while - I suspect it is from the glue (contact spray) causing the backing to expand but after using it so much on these 4 boxes it has almost disappeared. Mulling over some ideas to just clamp the ends under tension for the next version
