Bows and curved slopes with matching curvature

Recommended Posts

  I am attempting to put together a reference list for bricks which share a matching vertical curvature as a family.  These parts are scattered over multiple categories on BrickLink, hence why a centralized list would be useful.  To make the list, the parts must be able to touch matching a curve anywhere on the end faces.  The ones I am looking at first have a curvature of one stud horizontally and three plates vertically:

6091.t2.png6091 - Slope, Curved 2 x 1 x 1 1/3 with Recessed Stud (One plate height before curve.)

37352.t2.png37352 - Slope, Curved 1 x 2 x 1

6191.t2.png6191/10314 - Slope, Curved 1 x 4 x 1 1/3 (One plate height before curve. 10314 has raised reinforcement so a stud fits under the center stud holder.)

6081.t2.png 6081 - Slope, Curved 2 x 4 x 1 1/3 with Four Recessed Studs (One plate height before curve.)

6215.t2.png6215 - Slope, Curved 3 x 2 x 1 with Four Studs

4744.t2.png 4744 - Slope, Curved 4 x 2 x 2 Double with Four Studs (One brick height before curve.)

30165.png 30165 - Slope, Curved 2 x 2 x 1 Double with Two Studs

6192.t2.png 6192 - Slope, Curved 2 x 4 Double

6216.t2.png6216 - Slope, Curved 4 x 2 x 2 Triple

30075.t2.png  30075 - Slope, Curved 6 x 2 x 3 Triple with Eight Studs

6214.t2.png6214 - Slope, Curved 8 x 2 x 4 Triple with Eight Studs

67810.t2.png67810 - Brick, Modified 2 x 2 x 1 1/3 with Curved Top (One plate height before curve.  Outside curvature on corner is actually only one stud like 1x1 round corner tile.)

65617.t2.png65617 - Brick, Round Corner 3 x 3 x 1 without Studs

24599.t2.png24599 - Brick, Round Corner 5 x 5 x 1 without Studs

  Let me know if I've missed anything, or if there's a non-matching curve profile on any of these I didn't have on hand to compare physically.  Please don't quote my entire post in a response, or this thread is gonna get messy quick!  Cite specific examples.  If this works out well, I will continue with other curvature families.

  On a related note, efferman just fulfilled my dream of a 4x4 variant of the 65617 3x3x1 corner, which I've just ordered from ShapeWays:

  In future, I really wish LEGO would produce variants of the 6091 and 67810 without the plate sticking out the side, and preferably one brick high instead of 1-1/3 like they did with the 37352 and 65617.  (I had to cut the side plate off 12 of the 6091's before the 37352 was released and solved my problem, but there's still no solution for odd-numbered stud lengths.)  I also don't understand why the 24599 5x5 corner was made with the 4x4 curve filled in -  now the 27507 4x4 macaroni tile, 48092 4x4 macaroni brick, and numerous other items also matching this radius can't fit inside.  And speaking of macaroni, 3x3 tile and brick would be great to match the radius of the various 6x6 round pieces, and also the 3x3 quarter dome.  (I'm starting to drift off-topic though, and I don't have any immediate applications for such things anyway.)

  The following family has a curvature of two studs horizontally and two bricks vertically.  It is important to note that there are two slightly different variants of the curvature, which I will refer to as "New" and "Old":

New Curvature

29816.png 92903 - Brick, Arch 1 x 3 x 2 Curved Top

33243.png  *33243 - Slope, Curved 3 x 1 x 2 with Stud.  Bricklink notes multiple curvatures for this part but does not list multiple mold numbers.  I have 33243 in my collection.

88293.png  88293 - Brick, Round Corner 3 x 3 x 2 Dome Top

87559.png87559 - Brick, Round Corner 6 x 6 x 2

Old Curvature

29816.png 6005 - Brick, Arch 1 x 3 x 2 Curved Top
33243.png  *ID unknown - Slope, Curved 3 x 1 x 2 with Stud.  Bricklink notes multiple curvatures for this part but does not list multiple mold numbers.

6183.png *6183 - Brick, Arch 1 x 6 x 2 Curved Top.  Bricklink lists alternate mold number 24434 but does not say if it differs.  I have 6183 in my collection.
  Please let me know if any of you have in hand, and can confirm, the curvature of the alternate/missing mold numbers.
