Boys and Girls,

While following a totally unrelated bouncing ball…, a search of ”Leigh D4R” revealed quite a few reviews, blogs and projects centered around the jig. This indicates to me that there may be a wider range of members that relish in the benefit of their outlaid expense… (it wasn’t cheap).

If you hand cut your dovetails… bye.
If you use a PC dovetailer… or not a D4R... bye.

I’m not going to parrot past members contributions and little miss echo can go and have a sabbatical, however, if you are anything like me, the D4R is only brought out on special occasions like birthdays, bar mitzvahs, christenings, Ramadan, Christmas, goat sacrificial days and the occasional C19 lockdowns… and the specialised list goes on.

Needless to say, most of us D4R users have not memorised the manual (albeit one of the better instructional publication), and we cock up our board orientation and find we have to re-cut and route 1 or two extra boards. How many times have you pulled out a drawer only to find that the front actually pulls out… separating from the drawer itself, due to incorrectly cutting the tails on the front piece.
On this project, the sides got the pins,

For a cabinet, it was no biggie, but for a drawer it would’ve been an OOPSIE no-no.

Forget Mrs. Leigh’s henpeck of the Mr. with her inside and outside triangles…

Orientation the “box” based on esthetics and mark the boards S for sides and F for front (and back)…
Then remember the mantra,

FOP when you SIT
  • SITSide Inside Tail….
  • FOPFront Outside Pin…

Then when after you place the comb and mount the board, sing that mantra FOP when you SIT!!! And you won’t screw up… as often!

100% agree!

The manuals use of notation marks reminds me of the many crazy icon style signs that assault our eye

I still get hungry when I see this under the hand dryer in a restroom.

You forgot to mention that the D4 is beast. As with most beasts, you need to treat it with respect. Every time I use it, the the sacred user’s manual is opened, recited, and all of the sage advice contained within the tome is put forth into use.

Somehow, I still wind up with one or two “original” pieces that wind up with the wrong side out or tails where there should be pins.

I’ll leave the aftermath of the bacon in the dunny…

Aha, BTDT… remember the mantra and you’ll at least halve your odds… you’ll only wind up with ½ or 1 wrong pie...

The Wood Whisperer pretty much torched Leigh’s use of symbols in a video he did. He replaced the triangle and square symbols with an “I” and “O”

Get this, he proposed that the “I” stand for inside and the “O” stand for outside.

Yes it’s a good manual but you actually have to read it nearly every time you use it.
Therefore I use my Akeda.

Sooooo…. Bye.

I have to agree. With long times between using the jig, it is back to the manual each and every time. I will go through the book and add the I and O. That should keep me from #$%&**#^% it up again. I hope, but I know it will only be short time before I #$%^&*[email protected]%^ it up again.

Pinto – you just gave away the secret code for the D4. I write “inside” and “outside” on every board, and also include “top” as well as “front”, “back”, “left side”, and “right side”. Basically, I write a novella when I use the D4 but it helps things come out like they should more times than not.

After watching the spaghetti muncher and also used the I and O, I still managed to bugger it up…

Now I now write F and S for the position of the board as after I’ve decided which is which…
If I’m looking at a board marked F on one of it’s sides, I know it’s a FOP and ensure the chosen “outside face” is facing me and cut a pin or if the D4R is in the tail configuration, I work on the S boards…

Now, sing along with the duck…

♫♪♫
FOP when you SIT… tra la, FOP when you SIT… tra le, FOP when you SIT… tra li… O-o-ooo!

Download this, print it off, laminate it and glue it next to your D4R,
