Has anyone built their own dome port? I've used an 8" dome but was looking to test a ~17" dome for split shots on my Nauticam N120 DSLR housing. I looked at purchasing a dome port of this size and the Matty SMith ones look awsome but they are $2k+ which is way out of my budget. I've read a number of posts and watched videos online but didn't find anything on this forum.

I've read the "Barry Guimbellot designs DIY small dome port for CFWA" and it looks like there might be more info on wetpixels but I didn't get my account approved before it went down so I cannot access those forums.

I've wondered if the BluRov hemispherical dome ports could be used to make a fisheye port. They are cheap enough and very robust.

You need to contact this man, he's located in The Netherlands. https://www.corkuyvenhoven.nl

He built this ultra megadome for over/under shots.

And that's the other guy

Do you need 17"? the 12" domes are more affordable, about $US1500 delivered assuming you'll need to pay duties on the way in.

Nope, just wanted to experiment with larger domes and figured if I was going to make something I might as well go big, figured the larger I went from 8" the bigger the difference and if people are selling them there might be supplies available off the shelf to DIY, I assume they aren't getting custom molded domes. Truthfully I just want to experiment with one to see what it's like which is why I want to build one since I don't know how practical or useful it will be.

I have done my own dome ports, 4" with 3 different plexiglass curvature, I have change the plexiglass to a 8" old Sea&Sea dome port, for which I had to modify the fitting system,and a 17" dome port, which I don't have any picture right now and I lent it to a friend. When I have it again I can send you pictures, but basically is the same design of the pictures above.
