Compatibility of different inverse slopes?

uncleMonty

Hello, am attempting to plan brick purchases for an original build. I had a question about combining two different sizes of inverse 33 slope in a single sloping wall. Piece 3747 is the familiar 33 3x2 inverse slope, but there is also 4228 at the same angle, with dimensions 5 x 6 x 2. I haven't set hands on the larger one and am trying to visualise whether (and how) to combine both kinds of pieces, in a wall that isn't the right length for a whole number of 4228s. Can they be easily combined to make a wall of any (even) width in studs, and any height, that will look mostly uniform?

Thank you!

I don't have an actual 4228 part, but I did a quick comparison in LDD.

Hey thanks! The disparity in slope is acceptable for my purposes. How about building with one on top of the other (in either order), will that work too? Say I wanted a slope of height 5 bricks?

Also, sorry to ask for more, but: could you show me what your side-by-side construction looks like from the other side? (I can't use LDD myself until I update my super-old OSX install)

Just a suggestion, but you could always use 1x2 hinge brick and then make any angles you want and almost any length with brick and it would be uniform in terms of the slope as there would be no set backs because you could use brick instead of slope pieces

Unless you must use slope pieces, or the hinges would make it look weird, I would say you can try that

Simple geometry says you'll have the same slope no matter how you stack them.  It'll be 5 bricks high and 11 studs from front to back.  The little step will be nearer the top or bottom depending on what order you stack them, but the studs at the top will line up. 

Mind blown!  The 33 deg isn't actually the angle of the slope (i just got my protractor out!).  Looks like its 33 deg from centre of the anti-stud on the base of the brick, up to the base of the opposite stud at the top of the brick as shown rather crudely below.  Apparently I do learn something new every day :-)

You might want to check on quantities and cost for that giant inverted slope too. That has been out of production for many years and is probably not easy to come by.

Check colours as well, the big slope only comes in light grey, not the modern light blue-grey. If you want consistent colour you would have to get older small slopes as well.

If it's for a wall using just the small slopes will give a more even and realistic consistent 'stone' size, even allowing for a few other shades of grey to give better natural variation. Using 3x1 slopes with 3x2 also allowed for overlaps, stronger and again more realistic. Just depends what its for
