LEGO Techniques - Pony Leg

Maybe you're familiar with the Pony Ear technique from the 80's.  That's the one where you place a plate sideways between the studs of another element.  The name comes from the likes of sets 372, 617, and 697.  You can also see it used in the likes of 605 and 611.

The Pony Leg technique gets its name from a similar aspect as the Pony Ear.  Instead of connecting studs on top you connect edge to studs.  Though in this case we're connecting edge to bottom.  In any given plate 2x or larger there is a little miracle of LEGOnomics.  The distance between the inside edge of the lip and the outside of the anti-stud is in a tight tolerance to 3.2mm.  If you've followed my posts or understand LEGO maths, you'll instantly recognize this as the width of a plate sans stud.


I made a brief allusion to this dimension in two previous posts.  The first was with the bucket handle.  I had declared the 3.2mm diameter of the bucket handle to be the frictional force in the skinny 180° SNOT connection.  I later found it to be something else as well.  The second one was the roller skates where I showed the skate element doing the same thing that I'm talking about now.

It's nothing fancy but with a Bx1 plate it will let you do SNOT with a plate and a half of width in between.  That's due to the stud being 4.8mm in diameter.  Or use a tile and get about a plate and a quarter in between.

Now if you want to get really tricky, put a Bx2 tile in there.  That will give you another 2.5 plates of thickness, added to the 1.25 plates of thickness normally achieved.  Wait, where have I seen that number before?

I sure do <3 LEGO.
