Never seen anything like that before.The stair nosing can be metal, rubber or vinyl. You will have to make (inside) relief cuts to bend the material. I've done many linear feet of curved steps. Normally we use vinyl. Rubber is a better choice and a higher cost. I cant recall such a sharp curve though. First thought go to the many school stages with about 3-5 30'-40' wide steps up but it's a very modest radius so mostly just warm the vinyl and dont even require relief cuts.
Here's another few photos. Real dirty iphone lens. It fell into the cove base pail. Anyways, I had to square up the concrete step for the cheap plastic nosing.Never seen anything like that before.
I have ideas in my head but they're fighting to get out.
I used air conditioning duct work for my last steam chamber and I sold the steamer my wife threw away so I don’t have that anymore good luck
That's why I wish I had a shop to play with this sort of thing. I've watched people pull wood out of a steam chamber and bend it and it's amazing. It just looks like something that can't be done..... But it's done. If you set up a jig, I suppose you could laminate together two quarter or 3/8 in thick pieces to make the nose of course you need a lot of clamps.....That’s genius!
That’s a pretty tight bend for wood. You gotta have a form, clamps n all that stuff to bend and even then the wood may split while bending it. Not saying it can’t be done but if this is your first time I’d prolly go for gluing, cutting and routing raw wood to make one fit as opposed to steaming one and bending it into shape.
I gotta dig through my old phone cus I have some pics of curved stair nose I made.
