Secret Weapon Miniatures have posted a preview of work-in-progress versions of their upcoming Sewer Works – Round Lip bases.
From their website:
‘Sewer Works’ is the second set of bases coming to round lip before going to beveled (‘Iron Deck’ was the other). This is another set of hollow bases so you can add your favorite water product.
These three are work in progress masters and not resin casts. Each of these is made with plaster cast bricks. I will individually weather and chip the blocks to ensure a more realistic texture. I fill in the gaps with very thin sanded grout.
