I originally had the idea of the “impossible chain” – a chain hanging from a beam which it itself supports – about a year ago, but, until I’d managed to come up with a way of making decent thin strips of wood, I couldn’t really go anywhere with it.
Having got the drill press (thanks to whoever it was on here that said I should get one, even though I thought I didn’t need one – edit – it was, of course, vipond33 , to whom – gratitude), I can now “manufacture” fairly evenly thicknessed thin strips of wood.
Anyway – my previous effort was but a dress rehearsal for this chappie – a chain-based ”two cups of coffee and a packet of biscuits, please”.
I’ve spent a long time looking at it, and, frankly, I’m a bit disappointed – It’s OK, and it works, and it’s pretty well (although not perfectly by a long chalk) made – but it doesn’t really look like a chain hanging freely from a beam that it itself is supporting – I haven’t yet worked out quite why – and that was the aimpoint.
Still, should you be interested, this is how it came about…

My last chain was done by making a block with rounded sides, which I then sliced into links which were then thicknessed. I decided to take a different approach here, since the thicknessing was a dusty hassle, in that first I thicknessed strips, onto which I then put the end shape.

(You can see in this last picture the specially imported chinese bamboo dowels I’m going to use – since they were 3.2mm wide, but variable, it needed to be a special order)
or, of you don’t believe that, as well you might not…
(You can see in this last picture the bamboo barbecue sticks I’m going to use for dowels – I had occasion to use one a while back and was impressed with the speckled pattern)

Of course, this method presented some challenges…
I drilled the dowel holes in all the strips, and held them together for the round over bit…

Chop into links, drill holes, and repeat…

And we have a bit of chain…

(these are cocktail sticks – about half a millimetre slimmer, so loose in the holes)

For the base I’m going to use a bit of this scruffy old goodess-knows-what I found 3 years ago in the bins at the DIY store.

It’s a bout 6 mill thick, so I mount it on a bit of plywood and spend many happy hours trying to get it smooth.

Some oak for the cross pieces…

Now I have to do a through tenon thing. This will involve chiselling, so I spend 3 days trying to work out how I might avoid that, but fail, so I resign myself to it…

Now the fun begins.
How to make the chains the shape I want?
After some pondering, and more pondering, I came up with this…

...nails in a bit of flooring mdf in the right places.
And…

...it works! Or at least it works before glue is added.
I cut some strips so I can clamp the links together once they’re in the right place. The cocktail sticks are just to keep things together, as soon as it’s clamped I’m going to remove them.
Note also that the whole chain isn’t glued – the links at each end can, and will be, removed.

First I attach 2 sets of 3 to the handle, using the bottom for positioning.

I’ve already glued the first links to the base (of which I forgot to take a picture)
Then glue it all together in 2 passes.
First at the bottom…

Then at the top…

————————————————————————————————-

I think I’m done with chains for now :-)

Fumed oak and ash and unknown wood.
Linseed oil on all but the base, which was polished up from Danish Oil.

That was a detailed description of te chain making process however I think I would have stayed with slicing off links from rounded over stock.

I did a similar process making false tenons only 3/16” think. The reason I did it that way was that I wanted to chamfer the exposed face and a piece 3/4” x 1-1/2” x 3/16” was just to small to even think about getting near a router. I sized my stock, rounded over the four edges,chamfered the four to be exposed edges, and sliced to thickness. I had to make 32 of these!

However, your results belie your process, everything worked out, and you have a beautiful project.

By the way, check out Woodworking for Mere Mortals as Steve has a beautiful process for making links.

That turned out really well! Thanks for the detailed instructions. One thought I had … if the tray is hanging from the beam by the chain then the chain would be taut (without slack) and an undersized piece on the bottom of the tray to give the illusion of floating (OK that’s two thoughts). Anyway, thanks for sharing!
