Floating
Tennon Joinery, using beadLOCK
The term "Floating
Tennon" means the tennon is not physically part of either members of
wood joined to gether - you cut 2 mortices, and the tennon fits in these -
This can be done by hand, I thought i'd try out something very new here in
the UK - the Beadlock.
Heres how its done....
 |
Many
thanks to beadLOCK
Here I will be demonstrating
the beadlock set up in 3/4" mode, the model I am using also has
1/2" for bigger jobs.
You get the beadlock
jig, some shims, and 3/4 & 1/2" guides, and the beadlock tennon
stock. |
 |
So here are the 2
bits of stock I wish to join, I have prepared them, and made sure all
the custs are at 90 degrees, and jointed the edges for accuracy. |
 |
Butt them up together,
and make a neat mark over the centre, like you would do when cutting
biscuit slots. |
 |
The jig has a
half moon slot, so offer it up to the timber, and align the straight
bit with the index mark - this must be accurate.
Clamp the jig firmly
to the work piece, and hold it down to a bench, or even put it in the
vice.
You can see the
guide block is currently set to position A - this is changed later. |
 |
I am using a 3/4"
drill bit to make the mortise, its simple, just use the 3 holes in the
guide block to guide you, I've also put a bit of tape on the drill bit
to guide the depth. |
 |
I've moved the
guide block to position B by loosening the screws, and sliding it over.
Then tighten and drill the holes.
The end hole will
be blocked, as this isnt needed in position B. |
 |
I'm repeating
the process on my other part of the wood.
Remember:
- Line up mark with halfmoon on jig
- Firmly clamp to work
- Drill 3 holes in position A
- Drill 2 holes in position B
- Clean out excess chippings |
 |
Here you can see
the tennon stock, and how we have formed a simple, but effective mortise
using a hand drill, and the bead lock jig. |
 |
Now its time to work
on the tennon, first thing i'm doing is checking the depth of each mortise
-about 20 mm per mortise, so the tennon will need to be a little less
than 40mm. |
 |
Cut the needed
amount off like I am doing here, a small saw will do the job neatly.
Remove any burs
with some sandpaper for better results. |
 |
Apply glue to the
tennon evenly, and I also have put it in the mortises. |
 |
Here we go, one
clean, professional and strong looking joint.
Clamp it until the
glue dries, and your ready for some serious useage!
Why not buy a beadlock
jig!!?
