Hope someone can point me in the right direction here.
I have a cross to get made for the outside of a church. The photo enclosed shows roughly of how the construction should look as this exists on the inside of the building.
The new sign will have to be durable, have large stand off’s and be lit from the inside to create a glow.
My problem is the shape, it looks like a propeller and has a rounded front, any idea what this could be made from and who could help here? Not looking for wood though

My first thought would be back lit GRP, but could be expensive due to making the moulds. Or perhaps HDU foam board and hand shape it and spray paint?

I’d go stainless steel built up all the way. Lasts pretty much forever. If that ever lets go of the wall it will be seen as the beginning of the apocalypse

if its an exact replicate of the above, and you can take that cross for a period.
you could have it vacuum formed multiple times pretty cheap and would be exact duplicates.
you could simply colour it with vinyl and illuminate it from the rear with LEDs.
take a liquid latex mould of the cross and backfill the mould with liquid resin and take multiple moulds.
again, back-illuminated with LED modules.
Digitise the shape, plot in vinyl. apply to the likes of a 2mm Foamex PVC sheet and CNC router or jigsaw the shape.
back illuminate in led modules.
Digitise the shape, plot in vinyl. apply to HDU sheet and CNC router or jigsaw the shape. easy sand and shape by hand into the desired shape. this creates a lightweight and very durable cross. you then prime and paint it, and back illuminate in led modules.
have one fabricated by a professional in metal. the issue, or at least the expense part I see looking at it, is yes the surface is curved, but then tapers off flatter near the ends of the cross. You then have the returns. looks simple enough but I think fabricating it from a flat sheet is more difficult than it looks.
3D scan or 3D generated on PC and have it routered in 3D.
3D scan or 3D generated and have it 3D printed.
oh, and use a shower curtain ring or similar to get the circle in the middle. 😆
joking, but if self fabricating you could easily buy a ring to use in the build.
the simplest way to do it "in-house" with "no expensive equipment" would be to digitise the shape, plot in vinyl and jigsaw from a thick flat sheet.
If I had to try it like this, ide would use HDU and shape it by hand. it really depends on whether your craft levels are good enough for this, but look on the bright side, you might have plenty of time to perfect during the lock-down? :awkward: 😆 😆

Thanks for all the replies. Years ago I would have made this from wood and aluminium skinned it as it was my trade.
I like Robs idea:quote Robert Lambie:
Anyone know of a company to do this?
Signfab always good just looking for one other to quote
